Improved CTAB method for RNA extraction of thick waxy leaf tissues from sago palm (Metroxylon sagu Rottb.)

BackgroundThere is a growing interest in transcriptomics studies parallel to the advancement of transcriptome databases and bioinformatics, which provided the opportunity to study responses to growths, stimuli and stresses. There is an increase in demand for excellent RNA extraction techniques. General RNA extraction protocols can be used in RNA extraction, but the quality and quantity vary in different types of tissues from different organisms. Hence, a specific RNA extraction method for each organism’s tissue type is required to obtain the desired RNA quality and quantity.ResultsThe improved CTAB RNA extraction method is superior to the PCI method and MRIP method for thick waxy leaves that were applied for mature sago palm (Metroxylon sagu Rottb.) leaf tissue and produce total RNA extract with good purity (OD 260/280 ≥ 1.8, OD 260/230 ≥ 2.0) and integrity (RIN ~ 7). RNA sequencing was conducted with the extracted samples and showed good assembly results (Q20 ≥ 97, Q30 ≥ 91%, assembly mean length ≥ 700 bp).ConclusionThe improved CTAB RNA extraction method enables rapid, cost-effective, and relatively simple RNA extraction from waxy, fibrous and high-in-polyphenol sago palm (M. sagu Rottb.) leaf tissue with next-generation RNA sequencing recommended quality.Graphical

Karakteristik kematangan beberapa jenis sagu (Metroxylon sagu sp) siap panen menurut pemahaman masyarakat kampung Randawaya distrik Teluk Ampimoi kabupaten Kepulauan Yapen provinsi Papua

The purpose of this study was to study the maturity characteristics of several types of sago (Metroxylon sago sp) ready to harvest according to the Randawaya community, Kepulauan Yapen Regency. This research can give useful information for stakeholders in identifying the natural maturity of sago. This research was conducted using a descriptive method with a qualitative approach. From the results of interviews with the community, there are three stages of maturity of sago ready to harvest, such as: the early ripening phase which is marked by the opening of sago midrib, and the sago shoots shortening with the starch content is still low; the ripe phase which is marked by the midrib wrapping up to release shoots resembling a stump, and the starch is very dense; the late-ripe phase is characterized by the appearance of fingers resembling deer antlers and the sago sheath begins to wear off with the starch content of sago begins to decrease.

Direct Energy Conversion from <i>Metroxylon sagu</i> via Multienzyme Catalysis in Enzymatic Biofuel Cell

Biomass substrates have been used extensively in the production of biofuel by the simultaneous saccharification and fermentation (SSF) method. Biomass sources from the plant are preferable to produce biofuel because of the high sugar content. Adapting the SSF method, this work reported on the direct energy conversion from Metroxylon sagu via multienzyme catalysis in an enzymatic biofuel cell (EBFC). Metroxylon sagu locally called Sago is an industrial crop mainly found in Mukah, Sarawak. Sago is a type of starch that consists mainly of amylose and amylopectin structures. In this study, the polysaccharides are converted to glucose using alpha-amylase (α-amylase) and glucoamylase (GAmy) enzymes. The factors influencing the multienzyme catalysis, such as the substrate concentration, enzymes loading, pH and time, were varied to obtain the optimized condition for glucose production. The results of the glucose content using a microplate reader indicate that glucose was successfully produced via multienzyme catalysis. The oxidation of glucose employed in the EBFC was confirmed by the cyclic voltammogram (CV) analysis. The performance of EBFC was also assessed based on its maximum power density (MPD) and open circuit voltage (OCV) values. This multienzyme catalysis simplifies the multi-step process involved in converting polysaccharides to glucose.

Effects of Annealing on the Properties of Gamma-Irradiated Sago Starch.

The increase in health and safety concerns regarding chemical modification in recent years has caused a growing research interest in the modification of starch by physical techniques. There has been a growing trend toward using a combination of treatments in starch modification in producing desirable functional properties to widen the application of a specific starch. In this study, a novel combination of gamma irradiation and annealing (ANN) was used to modify sago starch (Metroxylon sagu). The starch was subjected to gamma irradiation (5, 10, 25, 50 kGy) prior to ANN at 5 °C (To-5) and 10 °C (To-10) below the gelatinization temperature. Determination of amylose content, pH, carboxyl content, FTIR (Fourier Transform Infrared) intensity ratio (R1047/1022), swelling power and solubility, thermal behavior, pasting properties, and morphology were carried out. Annealing irradiated starch at To-5 promoted more crystalline perfection as compared to To-10, particularly when combined with 25 and 50 kGy, whereby a synergistic effect was observed. Dual-modified sago starch exhibited lower swelling power, improved gel firmness, and thermal stability with an intact granular structure. Results suggested the potential of gamma irradiation and annealing to induce some novel characteristics in sago starch for extended applications.

Exploratory Studies on the Technical Viability of Bioethanol Production from Fermented Sago (Metroxylon sagu) Starch

This study was conducted to assess the viability of production of bioethanol from Metroxylon sagu Rottb. The experimental setup included different levels of yeast and molasses in the substrate. There were nine treatments examined in this experiment. The YIM1 (50g yeast, 150g molasses), Y2M1 (100g yeast, 150g molasses), Y3M1 (150g yeast, 150g molasses), Y1M2 (50g yeast, 200g of molasses), Y2M2 (100g yeast, 200g molasses), Y3M2 (150g yeast, 200g molasses), Y1M3 (50g yeast, 250g molasses), Y2M3 (100g yeast, 250g molasses), Y3M3 (150g yeast, 250g molasses). Experiment was monitored by their brix, temperature and time of fermentation. The results shows that higher the brix measured, has high yield of ethanol produced, among the treatments Y2M3 (100g yeast, 250g of molasses) gained higher yield of ethanol with 40.33% produced during first distillation. On the other hand, the lowest yield was Y3M1 (150g yeast, 150g molasses) with 17% gained of distillate from the mixture and has longer fermentation period. Using Analysis of Variance, RCBD, the level of significance was determined.

An in vitro study: prebiotic effects of edible palm hearts in batch human fecal fermentation system.

Edible palm hearts (EPH), known as palmito, chonta or swamp cabbage in America or umbut in Malaysia, is a type of vegetable harvested from palm tree species. EPH is firm and smooth and described as having a flavor resembling artichoke. It has underlying prebiotic potential that selectively stimulates the growth and activity of beneficial colonic microbiota, thus enhancing the host's health. This study is the first to present results of EPH from local species such as oil palm (Elaeis guineensis), sago palm (Metroxylon sagu) and coconut (Cocos nucifera) using in vitro colonic fermentation with human fecal slurry. Samples obtained at 0, 6, 12 and 24 h were evaluated by bacterial enumeration using fluorescent in situ hybridization (FISH), and short-chain fatty acids (SCFA) were analyzed by high-performance liquid chromatography (HPLC). All EPH samples revealed induction effects towards Bifidobacterium spp., Lactobacillus-Enterococcus and Bacteroidaceae/Prevotellaceae populations similar to those in inulin fermentation. A significant decrease (P ≤ 0.05) in pathogenic Clostridium histolyticum group was observed in the response of raw sago palm hearts. In general, all samples stimulate the production of SCFA. Particularly in the colonic fermentation of sago palm heart, acetate and propionate revealed the highest concentrations of 286.18 and 284.83 mmol L-1 in raw and cooked form, respectively. This study concluded that edible palm hearts can be a potential prebiotic ingredient that promotes human gastrointestinal health, as well as discovering a new direction towards an alternative source of functional foods. © 2022 Society of Chemical Industry.

Assessment of the genetic variations of sago palm Metroxylon sagu in three regions of Sarawak, Malaysia using amplified fragment length polymorphism (AFLP) marker

BackgroundSago palm (Metroxylon sagu) is an important staple crop in the rural area of Sarawak, Malaysia. The palms grow well in the rough, swampy peat, from low flooded areas to uplands and acidic to neutral soils. Among the starch-producing crops, this palm is the most productive and promising, where it can store a significant amount of carbohydrate in the trunk. Due to the lack of molecular study of sago palm, the work described here aimed to develop molecular markers for identifying M. sagu and accessing the genetic variations of sago palm in different locations of Sarawak.ResultsAmplified fragment length polymorphism was employed to determine the genetic variations of sago palm between fifteen populations collected from three different locations: Mukah, Pusa and Samarahan. Based on 35,016 polymorphic fragments generated from 32 primer combinations, polymorphic information content (PIC), marker index (MI) and resolving power (RP) averaged 0.269, 0.005157 and 51.52039 per primer combination, respectively, were obtained, signifying the effectiveness and accuracy of the AFLP marker. Mukah showed higher diversity (I = 0.428, H = 0.232), while Pusa showed the lowest (I = 0.367, H = 0.240). The average value of the Shannon information index was 0.404. AMOVA showed 99% of the variation was found within the population. The Mantel test was performed with 9999 permutations. A significantly positive correlation (r = 0.220, p = 0.010) was observed between the genetic divergence of the population (Nei genetic distance) with the geographical distance.ConclusionsOur study considered AFLP is as an effective and reliable method to assess the genetic variations and the identification of M. sagu.Graphical

Productivity of sago palms on smallholder plantations after rewetting in previously drained peatland: a case study on Tebing Tinggi Island, Riau Province, Indonesia

Sustainable land use through rewetting is becoming increasingly important in drained peatlands. We assessed the recovery of productivity of smallholder paludiculture using sago palm (Metroxylon sagu) in a rewetted peatland on Tebing Tinggi Island, Riau Province, Indonesia, which had been drained and burned in 2014. Stand structure and productivity of sago palms in smallholder plantations were measured in December 2016, November 2017, and March 2020. The sago stands were divided into three stands structure groups (pre-harvest stands, mid- to post-harvest stands, and growing period stands) according to gaps in the harvesting cycle, which were distributed in a mosaic pattern. Only those sago palms that had reached their maximum size were harvested, and as a result the mosaic pattern varied over time (spatial variation). The estimated harvest trunk height after rewetting was 8.9±1.5 m (mean±SD), which was not significantly different from that before drainage (9.7±0.4 m). The average annual yield of sago was 26.8 trunks ha－1, and there was large annual variation. Annual yield of paludiculture conducted after rewetting recovered to the same yield as that before drainage (26.0 trunks ha－1). Such size distribution patterns and large fluctuations in yield are characteristic of semi-traditional smallholder sago cultivation. Despite fluctuations in annual yield, harvesting only suitable individuals allows sago palms to be supplied every year. The findings obtained in this study will contribute to national and regional efforts to initiate paludiculture using sago palms.

Characteristics of sago growth and production in two sago-producing centers in the Kendari Peninsula, Southeast Sulawesi

Sago is an alternative food source crop, especially in Southeast Sulawesi. From year to year, the area of sago crops tends to decrease due to conversion and limited cultivation levels. Therefore, to preserve sago, it is necessary to identify and characterize sago growing in Kendari Peninsula. This study aims to identify and describe morphologically the types of sago found in sago-producing centers in the Kendari peninsula, Southeast Sulawesi. Observations were made on the different types of sago growing at two locations of sago planting centers. Parameter measurements were carried out on stem height, bark thickness, leaf width, leaf length, stem diameter, harvest age, and production per stem. The results showed that there were four types of sago found, namely roe (Metroxylon sagu R.), runggamanu (Metroxylon rumphii M.), and barowila (Metroxylon longispinum M.) and sago rui (Metroxylon microcantum). There are differences in sago vegetative and generative growth due to differences in growing environmental conditions and local climate. In general, the dominant types of sago in both locations were sago roe (Metroxylon sagus R.) and sago runggamanu (Metroxylon rumphii M.).

Association among Lepironia articulata Cyperaceae, peat soil and people in Wanggate, Mappi, Papua

Wanggate is a small village that is surrounded by water like a small island in the wetland area. A creek connecting to a main river is a mean of transportation to reach Mappi or another nearby village. Next to the river, population of grass were living and periodically waterlogged by the river. L. articulate, a species under Cyperaceae family, grows abundantly in small lake or pool that has connection to the river. Dark green color is a sign of L. articulata presence. The grass could reach up to 2 m tall and lives above water. Relationship among people, plants with peat soil has been present since a long time. The research was undertaken to understand more about the association. The nature of this study was descriptive with interviews to obtain ethnobotanical data. Fifty plot-wise sampling technique was used to collect data. The result shows that L. articulata shrub was the habitat of freshwater fishes like nila (Oreochormis niloticus), Channa sp. and shrimps. People has been dependent to fisheries from the lake and grasses for living. They make bags, arm straps, traditional hats, umbrellas, mats, kitchen utensils like baskets and plates, clothes and roofs from L. articulata. Peat soil was found in 31 plots and 28 of those plots were covered by L. articulata. Association index between of L. articulata and peat soil was 0.875 and dominance index of the plant was 0.868. The other plants, Melaleuca cajuputi, were found in 3 plots. The research discovered Paspalum conjugatum, grass-type vegetation, which associated with mineral soil like sago palm (Metroxylon sago).

Identification of gene transcripts contributing to trunking and non-trunking sago palm (Metroxylon sagu Rottb.)

Sago palm (Metroxylon sagu Rottb.) is an economically valuable crop and cultivated widely in Sarawak, Malaysia, for its storage starch. Under certain conditions, such as deep peat areas, some sago palms do not develop well and become stunted, described as non-trunking sago palms. Morphologically, this type of sago palm is abnormal, leading to wastage of various resources and affecting starch production. The research objective was to understand the molecular process that affects non-trunking and starch synthesis in sago palm. Representational Difference Analysis was performed to identify the differences between trunking and non-trunking sago palm transcriptome. This subtractive hybridisation technique detects the differences in gene expression. After three rounds of hybridisation, the differentiated RDA products were cloned and 24 DNA sequences obtained were compared with the sequences in the NCBI database. Results showed that the differentiated genes in response to the non-trunking sago palm have similarities to genes implicated in plant growth, cell metabolism, and salt or osmotic stress. Some of these genes are related to growth, development and signaling involving neutralising the imbalance in plant stress. The information obtained through this work could be used to develop a database on related genes and enzymes contributing to trunking and non-trunking sago palm.

Waterlogged Conditions Influence the Nitrogen, Phosphorus, Potassium, and Sugar Distribution in Sago Palm (Metroxylon sagu Rottb.) at Seedling Stages.

Sago palm (Metroxylon sagu Rottb.) grows in well-drained mineral soil and in peatland with high groundwater levels until complete submersion. However, the published information on nutrient uptake and carbohydrate content in sago palms growing under waterlogging remains unreported. This experiment observed sago palm growth performance under normal soil conditions (non-submerged conditions) as a control plot and extended waterlogged conditions. Several parameters were analyzed: Plant morphological growth traits, nitrogen, phosphorus, potassium, and sugar concentration in the plant organ, including sucrose, glucose, starch, and non-structural carbohydrate. The analysis found that sago palm morphological growth traits were not significantly affected by extended waterlogging. However, waterlogging reduced carbohydrate levels in the upper part of the sago palm, especially the petiole, and increased sugar levels, especially glucose, in roots. Waterlogging also reduced N concentration in roots and leaflets and P in petioles. The K level was independent of waterlogging as the sago palm maintained a sufficient level in all of the plant organs. Long duration waterlogging may reduce the plant’s economic value as the starch level in the trunk decreases, although sago palm can grow while waterlogged.

Ethnobotanical knowledge of Marind-Anim Tribe in utilizing sago (Metroxylon sagu) in Merauke, Papua, Indonesia

Abstract. Kadir A, Suharno, Reawaruw Y, Komari, Mahuze A. 2021. Ethnobotanical knowledge of Marind-Anim Tribe in utilizing sago (Metroxylon sagu) in Merauke, Papua, Indonesia. Biodiversitas 23: 264-272. Sago (Metroxylon sagu Rottb.) is one of the biological resources utilized by several communities, mainly in New Guinea and Moluccas region. In Papua (Indonesia New Guinea), sago is a source of food and is also used for the living needs of local people for generations. This study aims to explore the ethnobotanical knowledge regarding the utilization of sago by the Marind–Anim tribe in Merauke, Papua, Indonesia based on local wisdom. Data were collected using survey method and the analysis was done using qualitative approach. The research was conducted in 7 villages representing 6 sub-districts (Merauke, Sota, Tanah Merah, Kurik, Animha, Marind) in Merauke District. The results show that sago is an important resource for the Marind-Anim community to fulfill a wide range of needs from foods, building materials, and cultural activities. Each sub-tribe has a different perspective in grouping sago based on local knowledge. The difference is based on an understanding of the size of the tree trunk, the absence of thorns on the leaves, the height of the plant, the shape and size of the leaves, and the color of the stems/leaves. Based on local knowledge, there are at least five clusters of sago in the Merauke area across the villages surveyed. In Merauke, sago is processed into a traditional food called Sep, which is different from the people in the northern region of Papua, who process it into Papeda. In addition to Sago Sep, the community also knows other types of sago processing, namely Sago Ebayak, Sago Kwetahuk, and Sago Sinoli. The community has conducted conservation efforts based on local knowledge in Sar, Quality Sar, and selective cutting. The goal of such efforts is to maintain the sustainability of sago in meeting the needs for foods.

The Floodplain Forests of the Mamberamo Basin, Papua, Indonesia (Western New Guinea): Vegetation, Soils, and Local Use

New Guinea is the world’s largest, most speciose, and most culturally rich tropical island, and the little-studied Mamberamo Basin of Papua (Indonesian New Guinea) is recognised among the region’s most-important areas for biological diversity. Here, we examined the floodplain forests in the indigenous territory of Papasena, within the Mamberamo-Foja Wildlife Reserve in the Mamberamo Basin. As part of a training activity with local researchers, students, and civil servants, and with the permission and assistance of the local people, we employed various methods including the field surveys detailed here. We used variable-area tree plots, transects for non-trees and soil sampling, and local informants to document 17 plots: four in old-growth dryland forest, five in old-growth swamp forests (two seasonally flooded and three permanently wet including one dominated by sago, Metroxylon sagu Rottb.), five in secondary forest (fallows), and three in gardens (two in swamps and one on dryland). In total, we measured 475 trees over 10 cm in diameter at 1.3 m (dbh). The swamp forests had high local basal areas (highest value 45.1 m2 ha−1) but relatively low statures (20 m but with emergent trees over 40 m). In total, 422 morphospecies from 247 genera and 89 different families were distinguished. These included 138 tree species and 284 non-tree plant species. A quarter (105) of the morphospecies lacked species-level identifications. The woody families Rubiaceae, Araceae, Moraceae, and Euphorbiaceae were especially diverse, with 20 or more morphospecies each. Tree richness was highest in dryland forest (plot 7 having 28 species in 40 stems over 10 cm dbh) with more variation in the flooded forests. Non-tree vegetation showed similar patterns ranging from 65 species in one 40-by-5 m primary forest plot to just 5 in one seasonally flooded forest plot. The local people identified many plants as useful. Among trees, at least 59 species were useful for construction (the most common use), while, for non-trees, medicinal uses were most frequent. Inceptisols dominated (12 plots), followed by Ultisols and Entisols (3 and 2 plots, respectively). Drainage appeared poor and nutrient availability low, while land-suitability criteria implied little potential for crops aside from sago. We discuss the implication of local practises and more recent developments that may threaten the conservation of these floodplain systems. We underline the key role of local people in the oversight and protection of these ecosystems.

Rapid Ultrasound-Assisted Starch Extraction from Sago Pith Waste (SPW) for the Fabrication of Sustainable Bioplastic Film.

The present study was conducted to optimize the extraction yield of starch from sago (Metroxylon sagu) pith waste (SPW) with the assistance of ultrasound ensued by the transformation of extracted starch into a higher value-added bioplastic film. Sago starch with extraction yield of 71.4% was successfully obtained using the ultrasound-assisted extraction, with the following conditions: particle size <250 µm, solid loading of 10 wt.%, ultrasonic amplitude of 70% and duty cycle of 83% in 5 min. The rapid ultrasound approach was proven to be more effective than the conventional extraction with 60.9% extraction yield in 30 min. Ultrasound-extracted starch was found to exhibit higher starch purity than the control starch as indicated by the presence of lower protein and ash contents. The starch granules were found to have irregular and disrupted surfaces after ultrasonication. The disrupted starch granules reduced the particle size and increased the swelling power of starch which was beneficial in producing a film-forming solution. The ultrasound-extracted sago starch was subsequently used to prepare a bioplastic film via solution casting method. A brownish bioplastic film with tensile strength of 0.9 ± 0.1 MPa, Young’s modulus of 22 ± 0.8 MPa, elongation at break of 13.6 ± 2.0% and water vapour permeability (WVP) of 1.11 ± 0.1 × 10−8 g m−1 s−1 Pa−1 was obtained, suggesting its feasibility as bioplastic material. These findings provide a means of utilization for SPW which is in line with the contemporary trend towards greener and sustainable products and processes.
