Cowpea (Vigna unguiculata) is a legume consumed as a high-quality plant protein source in many parts of the world. High protein and carbohydrate contents with relatively low fat content and complementary amino acid pattern to that of cereal grains make cowpea an important nutritional food in the human diet. Cowpea has gained more attention recently from consumers and researchers worldwide due to its exerted health beneficial properties including anti-diabetic, anti-cancer, anti-hyperlipidemic, anti-inflammatory and anti-hypertensive properties...

There is increasing interest in the development of effective mosquito repellents of natural origin to reduce transmission of diseases such as malaria and yellow fever. To achieve this we have employed an in vitro competition assay involving odorant-binding proteins (OBPs) of the malaria mosquito, Anopheles gambiae, with a predominantly female expression bias to identify plant essential oils (EOs) containing bioactive compounds that target mosquito olfactory function. EOs and their fractions capable of binding to such OBPs displayed repellence against female mosquitoes in a laboratory repellence assay...

The cold-induced metabolic pathway and anthocyanin biosynthesis play important roles in plant growth. In this study, we identified a bHLH binding motif in the MdMYB15L protein using protein sequence analyses. Yeast two-hybrid and pull-down assays showed that MdMYB15L could interact with MdbHLH33. Overexpressing MdMYB15L in red-fleshed callus inhibited the expression of MdCBF2 and resulted in reduced cold tolerance but did not affect anthocyanin levels. Chip-PCR and EMSA analysis showed that MdMYB15L could bind the type II cis-acting element found in the MdCBF2 promoter...

Water insolubility is one of the major bottlenecks restricting the commercial availability of such food proteins as rice proteins (RPs), zein, etc. Here, we report that the structural hybridization of RPs and casein in a mass ratio of 1:0.01 can boost the solubility of RPs to over 90%. A structural analysis demonstrated that the backbones of the RPs and casein were integrated in basic solution (pH 12.0) and folded together into higher structures with subsequent neutralization. The hybrid backbones obtained improved the molecules' resistance to structural changes during neutralization, and formed protein bodies with appreciable exposed polar groups, which may have been buried in the absence of casein...

BACKGROUND: Targeting autophagy is emerging as a promising strategy in cancer therapeutics in recent years. Autophagy can be modulated to drive cancer cell deaths that are notoriously resistant to apoptotic-inducing drugs. In addition, autophagy has been implicated as a prosurvival mechanism in mediating cancer chemoresistance. Our previous study has demonstrated that Panduratin A (PA), a plant-derived active compound exploits ER-stress-mediated apoptosis as its cytotoxic mechanism on melanoma...

The present study aimed to determine whether hesperidin, a plant-based active flavanone found in citrus fruits, can prevent high glucose-induced retinal pigment epithelial (RPE) cell impairment. Cultured human RPE cells (ARPE-19) were exposed to a normal glucose concentration (5.5 mM) for 4 d and then soaked in either normal (5.5 mM) or high (33.3 mM) concentrations of D-glucose with or without different concentrations of hesperidin (10, 20, or 40 µM) for another 48 h. The survival rates of the cells were measured using a 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide reduction assay...

Meju, a cooked and fermented soy bean based food product, is used as a major ingredient in Korean traditional fermented foods such as Doenjang. We developed a novel type of Meju using single and combined extracts of Allium sativum (garlic clove), Nelumbo nucifera (lotus leaves), and Ginkgo biloba (ginkgo leaves) at 1% and 10% concentrations to improve the safety of Meju-based fermented products. Biogenic amines (BAs) in protein-rich fermented food products pose considerable toxical risks. The objective of this study was to investigate the effects of adding selected plant extracts in Meju samples during fermentation...

Quantitative real-time reverse transcriptase PCR (qRT-PCR) has become the method choice for quantification of gene expression changes, however, the accuracy of the method depends on the stability of reference genes. Ralstonia pseudosolanacearum (R. pseudosolanacearum) is an important plant pathogen, infecting >450 plant species and causing bacterial wilt. In order to identify stable reference genes in R. pseudosolanacearum CQPS-1 under different environment stresses. We used five tools (△Ct method, GeNorm, NormFinder, BestKeeper, and RefFinder) to evaluate the stability of seven candidate reference genes including phosphoglycerate kinase (PGK), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), 16S ribosomal RNA (16S), cell division protein ftsZ (ftsZ), DNA gyrase subunit A (gyrA), Ribosomal protein L13 (rplM), and phosphoserine aminotransferase (serC) under biotic (growth phases) and abiotic stress (temperature, hydroxycoumarins, nutrition)...

Pearl millet is a cereal crop known for its high tolerance to drought, heat and salinity stresses as well as for its nutritional quality. The molecular mechanism of drought tolerance in pearl millet is unknown. Here we attempted to unravel the molecular basis of drought tolerance in two pearl millet inbred lines, ICMB 843 and ICMB 863 using RNA sequencing. Under greenhouse condition, ICMB 843 was found to be more tolerant to drought than ICMB 863. We sequenced the root transcriptome from both lines under control and drought conditions using an Illumina Hi-Seq platform, generating 139...

Wheat ( Tritium aestivum L.) production is essential for global food security. Infection of barley yellow dwarf virus-GAV (BYDV-GAV) results in wheat showing leaf yellowing and plant dwarfism symptom. To explore the molecular and ultrastructural mechanisms underlying yellow dwarf symptom formation in BYDV-GAV-infected wheat, we investigated the chloroplast ultrastructure via transmission electron microscopy (TEM), examined the contents of the virus, H₂O₂, and chlorophyll in Zhong8601, and studied the comparative transcriptome through microarray analyses in the susceptible wheat line Zhong8601 after virus infection...

Mitogen-activated protein kinases (MPKs) play a central role not only in plant growth and development, but also in plant responses to abiotic and biotic stresses, including pathogens. Yet, their role in herbivore-induced plant defenses and their underlying mechanisms remain largely unknown. Here, we cloned a rice MPK gene, OsMPK4 , whose expression was induced by mechanical wounding, infestation of the striped stem borer (SSB) Chilo suppressalis , and treatment with jasmonic acid (JA), but not by treatment with salicylic acid (SA)...

Adipose tissue is a key organ with substantial senescent cell accumulation under both obesity and aging conditions. Chia seed is an ancient seed and is the richest plant source of α-linolenic acid. We aimed to determine how cellular senescence markers will be altered in adipose tissue of senescence-accelerated mouse-prone 8 (SAMP8) mice fed with high-fat diets (HFDs); and how chia seed can affect the above markers. SAMP8 mice and their control senescence-accelerated mouse-resistant 1 (SAMR1) were divided into four groups, that is, SAMR1 low-fat diet group (R1LF), SAMP8LF group (P8LF), SAMP8 high-fat group (P8HF), and SAMP8HF group supplemented with 10% chia seed (P8HC)...

The tea plant is an important commercial horticulture crop cultivated worldwide. Yield and quality of this plant are influenced by abiotic stress. The bHLH family transcription factors play a pivotal role in the growth and development, including abiotic stress response, of plants. A growing number of bHLH proteins have been functionally characterized in plants. However, few studies have focused on the bHLH proteins in tea plants. In this study, 120 CsbHLH TFs were identified from tea plants using computational prediction method...

Soybean is an important oil-producing crop in the Fabaceae family and there are increasing demands for soybean oil and other soybean products. Genetic improvement of soybean is needed to increase its production. In order to provide genetic diversity and resources for identifying important genes, a new ethyl methane sulfonate (EMS) mutagenized soybean population was generated using the newly released germplasm, JTN-5203 (maturity group V). Treatment of soybean seeds with 60 mM EMS concentration was found to be suitable for inducing mutation...

Lectin receptor-like kinases (LecRLKs) play important roles in plant development and stress responses. Although genome-wide studies of LecRLKs have been performed in several species, a comprehensive analysis including evolutionary, structural and functional analysis has not been carried out in soybean (Glycine max). In this study, we identified 185 putative LecRLK genes in the soybean genome, including 123 G-type, 60 L-type and 2 C-type LecRLK genes. Tandem duplication and segmental duplication appear to be the main mechanisms of gene expansion in the soybean LecRLK (GmLecRLK) gene family...

Previous studies suggest that GRAS transcription factors act as essential regulators, not only in plant growth and development but also in response to biotic and abiotic stresses. Recently, 53 GRAS proteins have been identified, but only a few of them have been functionally studied in tomato. Here, we isolated a novel GRAS transcription factor SlGRAS26, its down-regulation generated pleiotropic phenotypes, including reduced plant height with more lateral shoots, internode length, leaf size, even leaflets, accelerated flowering transition and decreased trichome number...

The 12 amino acid peptide derived from the Arabidopsis soluble secretory protein CLAVATA3 (CLV3) acts at the cell surface in a signalling system that regulates the size of apical meristems. The subcellular pathway involved in releasing the peptide from its precursor is unknown. We show that a CLV3-GFP fusion expressed in transfected tobacco protoplasts or transgenic tobacco plants has very short intracellular half-life that cannot be extended by the secretory traffic inhibitors brefeldin A and wortmannin. The fusion is biologically active, since the incubation medium of protoplasts from CLV3-GFP-expressing tobacco contains the CLV3 peptide and inhibits root growth...

Phosphoenolpyruvate carboxylase (PEPCase) mainly produces oxaloacetic acid for tricarboxylic acid (TCA) cycle. Here we reported that GhPEPC2 silencing with PEPC2-RNAi vector could regulate oil and protein accumulation in cottonseeds. In GhPEPC2 transgenic plants, PEPCase activities in immature embryos were significantly reduced, and the oil content in seed kernel was increased 7.3 percentages, whereas total proteins decreased 5.65 percentages. Compared to wild type, agronomical traits of transgenic plant were obviously unaffected...
