Improving Nutrient Uptake Efficiency in Hydroponic Systems With Phytoremediation of Nitrate‐Nitrogen Contaminated Wastewater

ABSTRACTThis study evaluates the efficacy of a nutrient film technique (NFT) hydroponic system in phytoremediation of nitrate‐nitrogen contaminated wastewater using six plant species: vetiver grass (Chrysopogon zizanioides), golden pothos (Epiprennum aureum), crotons (Codiaeum variegatum), arrowhead plant (Syngonium podophyllum), spinach (Spinacia oleracea), and brinjal (Solanum melongena). This study examines how well different plant species remove nitrate‐nitrogen from wastewater in an NFT hydroponic system. It finds that all plants, but especially money plant and arrowhead plant, successfully lower nitrate levels at influent concentrations of 30 and 90 mg/L. The wastewater had average pH values of 5–6.5, temperature values of 24°C–25°C, electrical conductivity values (EC) of 1.5–2 mS/cm, and total dissolved solids (TDS) between 1062 ± 199.3 and 1400 ± 124.16 mg/L. The system for golden pothos (70.94%–90.3%), crotons (62.5%–83.1%), arrowhead plant (67.25%–90.03%), vetiver grass (45.42%–83.1%), spinach (47.15%–81.71%), and brinjal (59.52%–83.38%) has shown excellent biochemical oxygen demand (BOD5) elimination efficiency. These results suggest that nitrate‐nitrogen contaminated wastewater can be effectively cleaned up by NFT hydroponic systems, which employ certain plant species.

A Systematic Review on Ethnobotanical and Pharmacological Aspects of Croton plant Codiaeum variegatum (L.)

Codiaeum variegatum (L.) known as garden croton, is a vibrant decorative plant, often identified as variegated laurel. It belongs to Euphorbiaceae, a spurge family plant with colourful leaves. Traditionally, the leaves of the Codiaeum species were used to treat a variety of ailments, including cancer, constipation, diabetes, digestive issues, external wounds, diarrhoea, fever, inflammation, intestinal worms, hypercholesterolemia, malaria, pain, ulcers, and weight loss. The juice of plant leaves induce menstruation. So, it can also be used to induce abortion. The root extract is used to relieve stomach ache and tooth ache. The leaves and shoots of the plant are reported to have varied chemical constituents like cardiac glycosides, saponins, tannins, cardenolides, flavonoids and steroids, which are responsible for the mentioned pharmacological activities. The goal of this article is to explore the botanical diversity, the pharmacological profile of C. variegatum as well as its chemical constituents. Variegatum (L.) is a well-known medicinal plant with nutritional and therapeutic uses, according to scientific studies. Given that, ornamental plants are an extraordinarily rich source of bioactive chemicals, more study might open the door to the development of value-added products to treat contemporary ailments.

Leaf Anatomy Structure of Codiaeum variegatum (L.) Rumph. ex A. Juss Cultivars

Codiaeum variegatum (L.) Rumph. ex a. Juss is a common ornamental plant with a high variation of leaves shape and colour. This study aimed to analyze the leaves’ anatomy and the phenetic relationship between eight cultivars of C. variegatum which were defined by the differences in leaf morphology. The paraffin method prepared the transversal section of leaves, and anatomical characters were converted into binary data to calculate the similarity coefficient which was analyzed by Numerical Taxonomy System (NTSYS) 2.1 version. Leaves of eight cultivars of C. variegatum are varied in the anatomical structure of the primary vein and lamina. The eight cultivars of C. variegatum were clustered into four. The variations were found in 19 primary vein and lamina anatomy characteristics and the similarity coefficient is up to 0.59 between all cultivars. It can be concluded that the combination of leaf anatomical structures and midrib anatomical characters have notable taxonomic implications for future research.

The six-spotted spider mite, Eotetranychus sexmaculatus (Riley) (Trombidiformes: Tetranychidae) in Australia, New Zealand, Japan and USA: a revised morphological and molecular-based concept, synonyms, and related species.

Based on morphological and molecular evidence, Eotetranychus asiaticus Ehara is confirmed as a junior synonym of E. sexmaculatus (Riley). Eotetranychus queenslandicus Manson differs to E. sexmaculatus in some morphological characters states, and currently there is insufficient evidence to confirm if it is also a junior synonym. We therefore propose that it remains a valid species until fresh material can be collected from the type host (Codiaeum variegatum (L.) A.Juss.; Euphorbiaceae) in the type location (Freshwater, Queensland, Australia) for molecular analysis and further comparisons. Eotetranychus sexmaculatus is confirmed as present in Australia and New Zealand. Our analyses indicate that specimens identified as E. sexmaculatus from avocado (Persea americana Mill.; Lauraceae) in Western Australia and New Zealand, and specimens of E. asiaticus from the type host (Ficus erecta Thunb.; Moraceae) and type location (Tomigusuku, Okinawa, Japan) are conspecific with specimens of E. sexmaculatus recently collected from the type host (Citrus sp.; Rutaceae) and type location (Florida, USA), with 0-3.6% divergence in a fragment (451 bp) of cytochrome oxidase subunit I (COI), and 0-0.3% in the ribosomal internal transcribed spacer II (ITS2) gene. Herein we redefine E. sexmaculatus, providing a revised diagnosis, notes on leg chaetotaxy, and variation in the shape of the aedeagus-which is a keystone feature critical for determining species boundaries of spider mite species that have males. Our findings also reinforce the potential of the eupathidion on the palptarsus suζ (i.e. the spinneret) for species diagnoses.

Study of controlling the content heavy metals Pb, Cu, Cd, and Cr in land using hyperaccumulator plants

This study aimed to determine the types of hyperaccumulator plants that can absorb the heavy metal content of Pb, Cu, Cd, Cr based on the values of bioaccumulation factors (BAF) and translocation factors (TF). Results of the analysis showed that BAF value of the hanjuang plant (Cordyline fruicosa), for heavy metal Pb was 0.369; Cu 0.442; Cd 0.055; Cr 0.078 and TF value for heavy metal Pb 1.572; Cu 0.964; Cd 0.108; Cr 1.358. Croton plant (Codiaeum variegatum), had a BAF value of Pb 0.021; Cu 0.060; Cd 0.000; Cr 0.003 and TF value of Pb 3.638; Cu 0.000; Cd 0.000; Cr 1.399. Sansevieria plant (Sansevieria trifasciata) had a BAF value of Pb 0.090; Cu 0.036; Cd 0.015; Cr 0.002 and TF value of Pb 0.410; Cu 0.334; Cd 0.222; Cr 0.726. Sunflower plant (Helianthus annuus) had a BAF value of Pb 0.022; Cu 0.094; Cd 0.308; Cr 0.001 and TF value of Pb 1.930; Cu 0.399; Cd 1.383; Cr 1.361. Based on a comparison of BAF values, hanjuang plant was the best hyperaccumulator plant capable of accumulating Pb, Cu, Cr with a phytoextraction mechanism and accumulating Cd with a phytostabilization mechanism. At the same time, sunflower a hyperaccumulator plant with the best translocation factor where the roots of sunflower plants absorbed Pb, Cu, Cd, Cr, which were then translocated to the stems and leaves optimally through a phytoextraction mechanism.

Anatomical Identification of Leaf Stomatal Cell Types in The Family Euphorbiacea

Stomata, which are specialized cells on the surface of leaves, undergo modification to form structures containing two guard cells. These cells play a crucial role in facilitating the exchange of water vapor and gases between the plant's internal environment and the surrounding atmosphere. Typically located on plant parts exposed to air, such as leaves, stems, and rhizomes, stomata distribution varies among different species. While some plants exhibit stomata on both upper and lower leaf surfaces, others, like water lilies, exclusively feature stomata on the upper side.The objective of the current investigation was to analyze the stomatal anatomy of various plant species within the Euphorbiaceae family. Employing a qualitative descriptive approach, the study aimed to characterize and interpret the stomatal types present on the leaves of Euphorbiaceae plants in the Langsa City region. The findings revealed the presence of five Euphorbiaceae species in Langsa City, including Euphorbia mili (jade fern), Jatropha curcas (Jatropha curcas), Codiaeum variegatum 'Norma' (norma puring), Codiaeum variegatum Bi (jet puring), and Codiaeum finger (finger puring), all of which exhibited parasitic stomatal types.

First report of a 'Candidatus Phytoplasma australasiaticum'-related phytoplasma strain associated with shoot proliferation disease of variegated croton in Taiwan.

Codiaeum variegatum (family Euphorbiaceae) is a leaf ornamental commonly known as variegated croton, which is often found in gardens or grown as indoor plants. In December of 2022, two cutting-propagated variegated croton plants exhibiting abnormal shoot proliferation and little leaf symptoms (Fig. S1) were found in a nursery owned by a private breeder in Wanluan Township, Pingtung County, Taiwan. The plants were propagated from a single stock plant, which died during transplanting from a commercial nursery in Changzhi Township, Pingtung County. To determine the potential cause of such symptoms, leaf tissues were collected from the center of the two symptomatic plants. Their DNA were extracted with a Synergy 2.0 Plant DNA Extraction Kit (OPS Diagnostics, Lebanon, NJ) and used for further testing. As controls, two symptomless stock plants were collected from the commercial nursery in Changzhi Township and used to produce cutting-propagated plants; leaf DNA was extracted from each plant as described above. The DNA samples were subjected to PCR testing using the phytoplasma-specific primer pair P1/P7 (Schneider et al. 1995), and only DNA from the symptomatic plants produced the expected 1.8-kb amplicon. The two phytoplasma isolates detected in the plants were designated as CvaA and CvaB. After sequencing and analyzing the data using the iPhyClassifier program (Zhao et al. 2009), both CvaA and CvaB were classified to subgroup 16SrII-A (GenBank accession no. L33765) with a similarity coefficient of 1.0. The near-full-length 16S rDNA fragments of the detected isolates (GenBank accession no. OR794242) were also identical (1,463/1,463 bp) to that of NCHU2014 (GenBank accession no. CP040925, bp 537768-539230), a reference 'Ca. Phytoplasma australasiaticum'-related strain (16SrII-A) found in Taiwan (Chang et al. 2015; Rodrigues Jardim et al. 2023). To validate the results, the DNA samples were also tested with 16SrII group-specific semi-nested PCR targeting the elongation factor Tu gene. The outer and inner primer pairs used were TUF-II-F1/TUF-II-R1 and TUF-II-F2/TUF-II-R1, respectively (Al-Subhi et al. 2017). An expected amplicon was detected in the symptomatic samples but not in the symptomless counterparts. The amplified fragments' sequences (GenBank accession no. OR634931) were identical to that of the elongation factor Tu gene of the 'Ca. Phytoplasma australasiaticum'-related strain NCHU2014 (989/989 bp; GenBank accession no. CP040925, bp 139344-140332). The protein translocase gene secY of the detected phytoplasma was also amplified and sequenced using semi-nested primers SecYF1(II), SecYF2(II) and SecYR1(II) (Lee et al. 2010). Again, the sequences of the detected isolates (GenBank accession no. OR862773) were identical to that of NCHU2014 (1,263/1,263; GenBank accession no. CP040925, bp 192846-194108). The quality of the DNA samples was confirmed by PCR targeting the plant host's 28S rDNA using primer pair 28KJ/28C (Cullings 1992) and all symptomatic and symptomless samples produced the target amplicon (0.7 kb). 16SrII phytoplasmas have been detected in different host plants in Taiwan (Chang et al. 2015). To our knowledge, this is the first record of this group of pathogens infecting variegated croton in Taiwan. Branch-inducing phytoplasma has been used to improve the ornamental values of poinsettias, another Euphorbiaceae species (Lee et al. 1997). Further testing is needed to determine whether the phytoplasma detected in this work could be used for similar purposes.

Anti-cancer effects of the extracts of broad and spirale cultivars of Codiaeum variegatum (L.) Blume on MCF-7, HepG2, and HeLa cell lines

Introduction: Codiaeum variegatum (L.) Blume is a well-known ornamental foliage plant used as a vegetable in northern Thailand, and it is the source of numerous bioactive substances. This work explored the effects of leaf extracts of broad (BCE) and spirale (SCE) cultivars of C. variegatum on three cancer cells, including human breast, human liver, and human cervical cancer cells. Methods: Ethanolic plant extracts were prepared, and then, 2,2-diphenyl-1-picryhydrazyl (DPPH), ferrous iron chelating, and lipid peroxidation assays were used to examine the flavonoid and phenolic compounds. The proliferative inhibition, growth, and migration of MCF-7, HepG2, and HeLa cancer cells, as a result of exposure to the extracts, were investigated. The extracts were investigated for their anti-cancer activities using sulforhodamine B (SRB), clonogenic, and wound-healing methods. Results: The data demonstrated that BCE and SCE contained high phenolic compounds. However, both extracts showed inactive anti-oxidant activities. Both extracts had high cytotoxicity on three types of cancer cells in a dose- and time-dependent manner after 24-72 hours of incubation with IC50 values in a range of 208-830 µg/mL. Moreover, the prepared extracts of C. variegatum significantly inhibited colony-forming ability and cell migration on all types of cancer cells. Compared with BCE, SCE showed more potent anti-cancer activities. Conclusion: These findings revealed that SCE had higher anti-cancer activities on MCF-7, HepG2, and HeLa cancer cells than BCE. Consequently, the SCE might be used as an effective chemotherapeutic compound for the prevention and treatment of cancer.

Natural vs. Artificial Light: A Study on the Influence of Light Source on Chlorophyll Content and Photosynthetic Rates on Indoor Plants

Indoor landscaping is an environmentally friendly approach that enriches the environment and fosters productivity and comfort for occupants. The practice of incorporating plants into interior spaces requires meticulous care to ensure healthy growth and prolong the benefits of interior greening. This study explores the impact of natural and artificial light, represented by fluorescent lighting on the growth and physiological responses of Codiaeum variegatum and Ardisia japonica. A natural light chamber and an artificial light chamber of identical dimensions were constructed to compare the plants’ physiological responses under consistent temperature, humidity, and illuminance conditions. The results indicate that Codiaeum variegatum and Ardisia japonica exhibited higher chlorophyll content and photosynthetic rates under natural light conditions compared to fluorescent lighting. Furthermore, the study found that natural light offers a rich spectral distribution across various wavelengths, providing an advantage for plant growth. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, the study emphasizes the importance of considering the rich spectral distribution of natural light when designing artificial lighting systems for optimal plant growth. In conclusion, understanding the effects of natural and artificial light on indoor plants is crucial to supporting plant growth and creating more effective indoor gardening solutions. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, natural light provides a more advantageous environment for growth compared to fluorescent lighting, with Codiaeum variegatum and Ardisia japonica both exhibiting a higher chlorophyll content and photosynthetic rate under natural light conditions.

Biophysical, Biochemical, and Photochemical Analyses Using Reflectance Hyperspectroscopy and Chlorophyll a Fluorescence Kinetics in Variegated Leaves.

The adjustments that occur during photosynthesis are correlated with morphological, biochemical, and photochemical changes during leaf development. Therefore, monitoring leaves, especially when pigment accumulation occurs, is crucial for monitoring organelles, cells, tissue, and whole-plant levels. However, accurately measuring these changes can be challenging. Thus, this study tests three hypotheses, whereby reflectance hyperspectroscopy and chlorophyll a fluorescence kinetics analyses can improve our understanding of the photosynthetic process in Codiaeum variegatum (L.) A. Juss, a plant with variegated leaves and different pigments. The analyses include morphological and pigment profiling, hyperspectral data, chlorophyll a fluorescence curves, and multivariate analyses using 23 JIP test parameters and 34 different vegetation indexes. The results show that photochemical reflectance index (PRI) is a useful vegetation index (VI) for monitoring biochemical and photochemical changes in leaves, as it strongly correlates with chlorophyll and nonphotochemical dissipation (Kn) parameters in chloroplasts. In addition, some vegetation indexes, such as the pigment-specific simple ratio (PSSRc), anthocyanin reflectance index (ARI1), ratio analysis of reflectance spectra (RARS), and structurally insensitive pigment index (SIPI), are highly correlated with morphological parameters and pigment levels, while PRI, moisture stress index (MSI), normalized difference photosynthetic (PVR), fluorescence ratio (FR), and normalized difference vegetation index (NDVI) are associated with photochemical components of photosynthesis. Combined with the JIP test analysis, our results showed that decreased damage to energy transfer in the electron transport chain is correlated with the accumulation of carotenoids, anthocyanins, flavonoids, and phenolic compounds in the leaves. Phenomenological energy flux modelling shows the highest changes in the photosynthetic apparatus based on PRI and SIPI when analyzed with Pearson's correlation, the hyperspectral vegetation index (HVI) algorithm, and the partial least squares (PLS) to select the most responsive wavelengths. These findings are significant for monitoring nonuniform leaves, particularly when leaves display high variation in pigment profiling in variegated and colorful leaves. This is the first study on the rapid and precise detection of morphological, biochemical, and photochemical changes combined with vegetation indexes for different optical spectroscopy techniques.

Thickness of Leaf Anatomical Tissue Dicot Ornamental Plants at Different Light Intensities

Different light intensities affect the leaf anatomy. This study aims to measure the thickness of the anatomical tissue of the leaves of six types of dicot ornamental plants at different light intensities. This study used a quantitative experimental method with a completely randomized factorial design (CRD-Factorial). This design consisted of two factors, namely the main factors were six types of plants, namely Codiaeum variegatum (L.) A. Juss., Bougainvillea glabra Choisy, Tabernaemontana divaricata (L.) R, Br. Ex Roem. & Schult., Syzygium paniculatum Gaertn, Excoecaria cochinchinensis Lour., and Aerva sanguinolenta BI. The second factor is the different light conditions (open and shading) with three replications. Parameters measured were total leaf anatomical tissue thickness, upper and lower epidermis, palisade, and spongy using a modified paraffin method from Johansen. Data were analyzed using the CRD-Factorial ANOVA model followed by the LSD test. Correlation done between palisade, spongy, and lower epidermis thickness with total tissue thickness. The results showed that the leaf anatomy of six types of dicot ornamental plants varied. All plants have one layer of upper and lower epidermis tissue. In Codiaeum variegatum (L.) A. Juss., Syzygium paniculatum Gaertn, and Excoecaria cochinchinensis Lour. has two layers of palisade tissue while the Bougainvillea glabra Choisy, Tabernaemontana divaricata (L.) R,Br. Ex Roem. & Schult. and Aerva sanguinolenta BI has one layer of palisade tissue. Meanwhile, the spongy tissue in all plants has one layer of tissue. The thickness of the leaf tissue decreased in the shading area along with the depletion of the palisade, spongy, and lower epidermis tissue as indicated by a correlation from moderately strong to very strong. Shrinkage of palisade tissue, sponges, and lower epidermis is a plant's attempt to get optimal light in shading areas. The more lower epidermis srink, the thickness of leaf become thin while the thickness of palisade and sponge varied so the thickness of total leaf from each species also varied.

Hydro-Alcoholic Leaf Extract and Fractions of <i>Codiaeum variegatum</i> (var. Mollucanum) Exhibited an Improved Anti-Amoebic and Moderate Anti-Oxidant Potential

Amoebiasis, classified as the third intestinal parasitic infection, represents a public health problem in low-income countries where hygiene and sanitation conditions are poor. With the resurgence of resistant pathogenic strains as well as ancestral considerations in developing countries such as Cameroon, many people rely on medicinal plants to treat a plethora of diseases. This work aimed to highlight the anti-amoebic and anti-oxidant potential of Codiaeum variegatum extracts and fractions. The anti-amoebic potential of C. variegatum was assayed on the polyxenic culture of the clinical isolates of E. histolytica. Then, the anti-oxidant potential of the ethanolic/hydroethanolic extracts and fractions was evaluated through DPPH radical scavenging, iron reduction (FRAP), lipid peroxidation inhibitory potential and total antioxidant capacity tests followed by the determination of phenolic compound and flavonoid content. It was found that the fractionation process decreased the amoebicidal activities of C. variegatum leaf extracts. However hydroethanolic extract (CI50: 10.08 ± 0.42, 5.18 ± 0.09, 5.18 ± 0.09 μg/mL respectively after 24, 48 and 72 hours) was more active than ethanolic extract (CI50: 15.59 ± 6.17; 9.61 ± 2.37; 6.26 ± 3.22 μg/mL respectively after 24, 48 and 72 hours). Interestingly, the activities of hydroethanolic extract were significantly non-different compared to metronidazole CI50: 8.42 ± 0.44, 6.45 ± 0.22 and 3.42 ± 0.33 μg/mL, respectively after 24, 48 and 72 hours). Ethanolic extract and EF5 showed higher Phenolic compound contents and higher antioxidant activity than hydroethanolic extract and other fractions through DPPH radical scavenging power (EC50 = 311.50 ± 4.12 μg/mL) and total antioxidant capacity (44 ± 0.07 mgEAA/gF). However, these activities are significantly lower than those of ascorbic acid (EC50 = 31.20 ± 4.39 μg/mL, and 61.34 ± 4.42 μg/mL respectively). This low antioxidant activity was confirmed by poor phenolic and flavonoid compounds contents found in the extracts and fractions. The present result brings a new approach to the ethnopharmacological uses of C. variegatum against dysentery in cases associated with Amoebiasis in Cameroun.
