Identification of F-box gene family in Brassica oleracea and expression analysis in response to low-temperature stress

Unfavorable climatic conditions, such as low temperatures, often hinder the growth and production of crops worldwide. The F-box protein-encoding gene family performs an essential role in plant stress resistance. However, a comprehensive analysis of the F-box gene family in cabbage (Brassica oleracea var capitata L.) has not been reported yet. In this study, genome-wide characterization of F-box proteins in cabbage yielded 303 BoFBX genes and 224 BoFBX genes unevenly distributed on 9 chromosomes of cabbage. Phylogenetic analysis of 303 BoFBX genes was classified into nine distinct subfamily groups (GI-GIX). Analysis of the gene structure of BoFBX genes indicated that most genes within the same clade are highly conserved. In addition, tissue-specific expression analysis revealed that six F-box genes in cabbage showed the highest expression in rosette leaves, followed by roots and stems and the lowest expression was observed in the BoFBX156 gene. In contrast, the expression of the other five genes, BoFBX100, BoFBX117, BoFBX136, BoFBX137 and BoFBX213 was observed to be upregulated in response to low-temperature stress. Moreover, we found that the expression level of the BoFBX gene in the cold-tolerant cultivar “ZG” was higher than that in cold-sensitive “YC” with the extension of stress duration, while expression levels of each gene in “ZG” were higher than “YC” at 24 h. Knowledge of the various functions provided by BoFBXs genes and their expression patterns provides a firm theoretical foundation for explaining the functions of BoFBXs, thereby contributing to the molecular breeding process of cabbage.

Agronomic biofortification of calcium in cabbage (Brassica Oleracea var capitata) applied with different sources of liming in Ca deficient acidic soil of Coonoor, The Nilgiris (Typic Dystropept)

The human body needs calcium (Ca) to maintain strong bones and teeth and to build a strong structure, helping muscles contract and playing a crucial role in the structural and signalling process. However, low calcium consumption in the diet has related to a variety of disorders in humans, which can have long-term health repercussions. Therefore, this study aimed to evaluate the Ca biofortification capacity of cabbage (Brassica oleracea var capitata) supplied with different Ca-supplying inorganic fertilizer sources at various fixed levels based on soil liming potential grown in open field conditions where four hybrids of cabbage grown in Ca deficient acidic soil. Ca applied as Limestone (CaCO3) (150% and 175% liming potential) and Dolomitic limestone [CaMg(CO3)2]150% liming potential yield high Ca content in cabbage head and foliage (61.3 mg 100 g-1), high glucosinolates content (53.12 mg 100 g-1) and lower oxalate(0.31 mg 100 g-1) that produced firmer head as compared with Ca untreated control which also promoted high market value for Ca biofortified ones. On the other hand, Ca addition leads to lower Fe and Mg content in the cabbage tissues due to an antagonistic effect. All four hybrids of cabbage studied using the agronomic method of biofortification significantly(p≤0.05) improved Ca enrichment (20% more compared to control) without showing any toxicity symptoms making possibility to obtain Ca biofortified cabbage in acidic soil of a hilly ecosystem by application of liming.

Assessment of Physical Suitability of Soils for Vegetable Production in the Libga Irrigation Scheme, Northern Region, Ghana Using the Analytic Hierarchy Process and Weighted Overlay Analysis

Assessing the suitability of soils for agricultural production is critical in promoting sustainable agriculture. Knowledge gained from soil suitability analysis provides the sound basis for making informed decisions about soil management and crop selection in a given area. In view of this, this study was carried out to assess the physical suitability of soils in the Libga Irrigation Scheme for the sustainable cultivation of jute mallow (Corchorus olitorius), tomato (Solanum lycoperscum L.) and cabbage (Brassica oleracea var capitata). Soil samples were collected at 0–30 cm and 30–60 cm depths from 50 geo-referenced points located at the nodes of a 100 m × 100 m regular grid. Particle size distribution, bulk density, total porosity, field capacity, permanent wilting point, available water capacity, saturated hydraulic conductivity, electrical conductivity and pH were determined following standard laboratory protocols at the AGSSIP Laboratory of the University for Development Studies, Nyankpala campus, Ghana. Weighting of soil properties was achieved through the analytic hierarchy process (AHP). Soil suitability maps for the selected crops were produced using weighted overlay analysis in ArcGIS (10.5). The results showed that generally about 44.3 ha (76.4 %), 44.7 ha (82.2 %) and 55.7 ha (96.0 %) of the irrigation field are moderately suitable for jute mallow, tomato and cabbage production respectively. The major limiting factors for the crops were high BD and acidity levels. The AHP proved to be a very useful tool for the incorporation of farmers’ views into decision making about the suitability of soils for crop production.

Green synthesis of silver nanoparticles from anthocyanin extracts of purple cabbage (brassica oleracea var capitata) and its characteristics for dye-sensitized solar cells (DSSC) application

We extracted natural dye from purple cabbage (PCE) and green-synthesized the silver nanoparticle (AgNPs) from this extract for the light-harvesting material in DSSC. The anthocyanin was extracted with the maceration method for 24 hours with solvent variation (distilled water (DW), ethanol and methanol), followed by synthesized AgNPs. From FTIR, we found that the absorption area of anthocyanin at 1629 cm−1 correspond with stretch vibration of C=O shifted to 1608 cm−1 in AgNP, indicates the presence of amine group or flavanones group. The PCEs showed an amorphous non-Bragg diffraction peak at a range of (15-25)°. AgNP’s diffractogram showed an intense peak at around 37.94° originates from Ag. Visible light range absorption observed, peaked at (421, 480, 550, and 966) nm, (415 and 544) nm, and (409 and 544) for PCEs in DW, ethanol, and methanol, respectively. The peak at 550 nm that comes from aglycone group in anthocyanin would be disappeared in the AgNPs that was made by dissolving AgNO3 in DW, ethanol, and methanol. The energy gap was (2.37, 3.00, and 3.03) eV for PCEs in DW, ethanol, and methanol, respectively, and (3.20, 3.30, and 3.31) eV for AgNPs. The reduction current originated from the Faradaic process (dark and irradiated condition) was detected in the extract with DW and ethanol as solvent, while it was not noticeable in methanol. This reduction current was detected for all solvents in AgNP positioned at a positive voltage of 0.2V. To be used as a light absorber in DSSC, one must choose the dye solution with the smallest energy gap without or small reduction current.

Lowering Breast Pain Postpartum Cabbage (Brassica Var Capitata) and Aloe vera Compress

BACKGROUND: Pain was the body’s way of telling us that something was wrong. Breast engorgement caused pain which affected the breastfeeding process. In the Kamonji Health Center area, there were 47 postpartum mothers who experienced breast pain AIM: The purpose of this study was to determine the difference in the effectiveness of giving cabbage compresses (brassica oleracea var capitata) with Aloe vera compresses to reduce breast swelling pain in postpartum mothers in the Kamonji Health Center area METHODS: This type of research was quasi-experimental with a two-group pretest–posttest design. The sampling technique was consecutive sampling with samples n1 = n 2 = 15 for each group of cabbage compresses and A. vera compresses. Data processing used the paired sample t-test. RESULTS: The results showed that the reduction of breast pain in postpartum mothers by giving cabbage compresses (brassica oleracea var capitata) was more effective than A. vera compresses with an average difference of 0.267. However, the second intervention has the same effectiveness in reducing breast pain in postpartum mothers, this can be assumed by the significant value of the second intervention is 0.000 p < 0.05 CONCLUSIONS: This study concluded that postpartum mothers who experienced breast swelling pain could apply cabbage compresses with A. vera compresses as a non-pharmacological therapy to reduce breast swelling.

Intercropping with Oyster Mushroom (Pleurotus columbinus) Enhances Main Crop Yield and Quality

This research trial was conducted in the open field to assess the integrated cultivation of oyster mushroom Pleurotus columbinus and field-grown vegetable crops. Oyster mushroom intercropped within cabbage (Brassica oleracea var capitata) and cauliflower (Brassica oleracea var botrytis) rows at the beginning of even head or curd formation. Data revealed superior intercropped cabbage and cauliflower growth parameters and higher yields compared with the respective sole cultivation. Pleurotus columbinus fruiting bodies weight, cab diameter, and total yield were significantly higher for mushroom intercropped with cauliflower than with cabbage. However, no differences or inconsistent differences were observed in fruiting bodies number, cab thickness, stem length, and stem diameter. Analysis of some mushroom fruiting bodies chemical composition showed that mushroom/cabbages intercropping surpassed mushroom/cauliflower intercropping in total phenols. However, no significant difference was observed between cabbages and cauliflowers concerning crude protein, total antioxidant activity, and total flavonoids. It is concluded that oyster mushroom/cabbage or cauliflower intercropping can provide additional marketable protein-rich food as well as enhance cabbage and cauliflower crop productivity based on sustainable practice.

Effect of drought length on the performance of cabbage (Brassica oleracea var capitata) in the forest-savannah transition zone, Ghana

The drought tolerance of Cabbage, Brassica oleracea var capitata (Oxylus) was investigated by subjecting the initial, development and mid growth stages to varying drought lengths of 5, 7, 9, 11, 13 and 15 days in a 7 × 3 factorial experiment to determine the effect of each drought period at each growth stage on growth and yield. Data on number of opened leaves/plant, leaf area index (LAI), leaf chlorophyll content, head size and yield/ha were recorded due to drought effect at each growth stage. Analysis of variance at 5% probability level indicated that drought periods of 5–15 days at the initial stage significantly reduced number of leaves, LAI and head size. Significant reduction in chlorophyll content and yield were due to drought beyond 11 and 5 days respectively at the initial stage. Number of opened leaves increased significantly with increasing drought length at the development stage; critical at 11 days drought. Significant reductions in LAI at the development and mid stages were critical at 11 and 9 days respectively whilst chlorophyll content was significantly reduced at both the development and mid stages by all drought periods. Significant reduction in head size at the development and mid stages was critical at 7 days. Generally, the drought tolerance of cabbage increased from the initial to the mid-stage. To maintain economic yields of cabbage in the forest-savannah transition zone, the initial and development stages could tolerate drought stress up to 5 days whilst the mid stage could tolerate up to 7 days.

Anti-dandruff shampoo formulation with active substances Ethanol extract of Brassica oleracea var capitata L. and its verifying activity against fungus Malassezia furfur

Traditionally cabbage (Brassica oleracea var. capitate L.) is often used by Indonesian society to deal with itching on the scalp due to the fungus Malassezia furfur which causes dandruff. Based on the results of previous studies, the antifungal activity test of cabbage leaf ethanol extract shows that ethanol extract has antifungal activity against Malassezia furfur. fungus. This research, an anti-dandruff shampoo formulation was carried out with the active ingredient of cabbage ethanol extract and verifying its activity test on M. furfur by diffusion method for the perforation method. The results showed that the preparation of anti-dandruff shampoo with active ingredients of cabbage ethanol extract had antifungal activity against M. furfur. The greater the concentration of cabbage ethanol extract in the shampoo, the greater the inhibitory power produced against M. furfur. Shampoo preparations made with cabbage ethanol extract concentrations of 15% and 30% had color, odor, shape, viscosity, surface tension, pH, high foam, and potential for anti-dandruff to be sufficient, safe to use, and stable for 8 weeks of storage. The anti-dandruff shampoo with 45% cabbage ethanol extract experienced changes in color, odor, and decreased viscosity during storage. It concluded that formulation shampoo with 15% but not higher than 45% cabbage ethanol extract suitable for an anti-dandruff shampoo.

The impacts of traditional homegarden conversion into the commercial one: A case study in Sukapura Village of the Upstream Citarum Watershed, West Java, Indonesia

Prihatini J, Iskandar J, Partasasmita R, Nurjaman D. 2018. The impacts of traditional homegarden conversion into the commercial one: A case study in Sukapura Village of the Upstream Citarum Watershed, West Java, Indonesia. Biodiversitas 19: 1926-1940. In the past, rural homegardens in West Java were planted with various annual and perennial crops. As a result, the vegetation structure of traditional homegardens in rural areas of West Java, Indonesia was very complex, similar to that of forest vegetation. Nowadays, however, due to rapid development of market economic system in rural areas, many traditional homegardens in West Java have been converted into the commercial ones. Consequently, the structure and functions of the homegardens have drastically changed. For example, the vegetation structure has become simpler and dominated by commercial crops, and the gardens serve mostly economic function instead of providing various ecological, socio-economic and cultural functions. The aim of this study was to elucidate: (i) the ecological history of traditional homegardens, (ii) the changes of structure and functions of the homegardens converted from the traditional into the commercial one, and (iii) the positive and negative impacts of conversion of the traditional homegardens into the commercial ones in the Village of Sukapura, the Subdistrict of Kertasari, the District of Bandung, Upstream Citarum Watershed, West Java. The combination of qualitative and quantitative methods were used, while some techniques, including observations, and in-depth interviews with competent informants were applied in this study. The results of study showed that initially the traditional homegardens in Kertasari Village had been predominantly cropped with various annual and perennial crops. However, due to market economic development, the homegardens have been drastically changed. For example, the commercial vegetable crops, including Welsh onion (Allium fistulosum L), carrot (Daucus carota L) and cabbage (Brassica oleracea var capitata) have been predominantly cultivated in the commercial homegardens. Consequently, the household income of the village people who own the commercial homegardens increased, however, some ecological and socio-cultural functions of the commercial homegardens drastically decreased. In addition, some negative impacts of the commercialization of the homegardens have occurred. We suggest that to develop the sustainable village homegardens for the future, the diversity of plants must be maintained to provide ecological function or ecosystem services and the economic production must be improved to increase the income of the rural people.

Organic manure and arbuscular mycorrhizal use on cabbage production

La utilización de bioinoculantes e insumos naturales es una alternativa viable en la producción de cultivos. El propósito del estudio consistió en comparar el 100 % de fertilización convencional (100N-40P-00K, testigo) con el efecto de gallinaza, la inoculación del hongo micorrícico arbuscular (HMA) Rhizophagus intraradices (micorriza INIFAP) y 50 % de fertilización química, independientes o en combinación sobre variables de planta, macollo y rendimiento de repollo (Brassica oleracea var capitata, cv. ‘Copenhagen Market’). En semillero se comparó la emergencia de plántulas crecidas en sustrato con y sin HMA. En campo se evaluó clorofila, diámetro de planta, diámetro y peso de macollo y rendimiento. Además, el beneficio-costo (b/c) fue estimado para cada tratamiento. La inoculación micorrícica incrementó significativamente en 19 % la emergencia de plántulas en comparación con las no inoculadas. El crecimiento y rendimiento mostraron diferencias no significativas entre los tratamientos. Los resultados indicaron la factibilidad de restringir 50 % o sustituir la fertilización sintética convencional mediante el uso de gallinaza y micorriza arbuscular en la producción de repollo. El tratamiento más rentable (b/c= 4.7) fue el de inoculación micorrícica en almácigo y la adición del 50 % de la fertilización química (50N-20P-00K).

Effect of different levels of nitrogen and microbial inoculants on yield and quality of cabbage (Brassica oleracea var capitata) cv Pride of India

The present investigation was carried out at Bihar Agricultural University, Sabour during rabi season of 2010-11 in Factorial Randomized Block Design (RBD) for yield and quality contributing characters. The microbial inoculant (Azospirillum) significantly reduced the number of days taken to head initiation (54.74 days). The plants developed under nitrogen level of 150 kg N/ha along with microbial inoculant Azospirillum significantly produced the highest average head weight (1.653 kg) per plant. The highest head yield (527.09 q/ha) was obtained with the use of microbial inoculant Azospirillum and proved its superiority over Azotobacter. For quality components the lowest moisture content in head (80.00%) was associated with nitrogen level of 200 kg N/ha + Azospirillum. Moreover, the highest dry weight per head (117.62 g) was associated with nitrogen level of 150 kg N/ha. The plants grown at nitrogen level of N0 (0 kg N/ha) produced significantly maximum ascorbic acid in head (86.46 mg/100 g). Therefore, it may be concluded that application of microbial inoculants basically Azospirillum as seedling treatment as well as soil application of nitrogen @ 150 kg/ha was the most effective treatment combination for higher yield and quality in cabbage.

Assessment of Heavy Metals in Some Vegetables Sold in Urban Open Markets of Kathmandu Valley

Present study describes the extent of heavy metal contamination in two vegetable types viz., cabbage (Brassica oleracea var capitata) and cauliflower (Brassica oleracea var botrytis) sold in urban open markets of Kathmandu valley. A total of 18 vegetable samples collected from various market sites of the valley were analyzed for heavy metals viz., As, Cd, Cu, Hg, Pb and Zn using atomic absorption spectrophotometer (AAS). Results revealed that the metal concentrations in both the vegetables tested were found in the order as Zn>Cu>Pb>Cd. The metal levels in cabbage leaves irrespective of the market sites, ranged between 0.91–2.05 mg/kg for Cd, 14.32-28.31 mg/kg for Cu, 7.29–14.70 mg/kg for Pb and 36.33–108.09 mg/kg for Zn respectively. Similarly, the metal levels in cauliflower varied from 0.81–1.50 mg/kg for Cd, 19.29–26.77 mg/kg for Cu, 10.82–21.23 mg/kg for Pb and 62.45–73.72 mg/kg for Zn respectively. However, As and Hg were found below the detection limits in both the vegetables tested. It was also found that while the mean concentrations of Cd and Pb exceeded the maximum permissible limits for vegetables, Cu and Zn were found within the safe limits as recommended by FAO/WHO. From the present study, we conclude that a regular monitoring of heavy metals in vegetables is necessary for safe consumption as well as to prevent excessive buildup of these metals in the human food chain.DOI: http://dx.doi.org/10.3126/njst.v15i1.12008 Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 39-44
