Oxidant Status

Effect of tannery effluent on the growth and anti oxidant status of Vigna radiata (L.) R. Wilcz. was investigated in 2009. Plants were grown in two dilutions and the results were compared with the control plants grown simultaneously in the same condition. Enzymic and non-enzymic antioxidants were analyzed in the grains. The antioxidant enzyme superoxide dismutase was found increased when the concentration of the effluent increased. Where, the concentration of catalase, peroixidase, glutathione system, polyphenol oxidase, ascorbic acid, tocopherol, polyphenol, lycopene and carotenoid were decreased when the concentration of the effluent increased. This study proves that Vigna radiata should not be grown in the soil having highest level of tannery effluent for maintaining human health and the environment.

The Impact

Background: In our previous study, six cultivars of Mungo (Vigna radiata) were exposed to 100-250 mM NaCl and studied for changes in growth and biomass. Among them AEM-96 cultivar of the Mung bean [Vigna radiata (L.) Wilczek cv.] was found to tolerate the NaCl stress at 250 mM. Objective: The soluble proteome of salt-tolerant mungo cultivar (AEM-96) was compared to the proteome of control mungo to work out the possible mechanism of salinity tolerance. Methods: Gel-based two-dimensional gel electrophoresis was employed for comparative proteomics. PDQuest-based image analysis of 2D SDS-PAGE was performed. Scatter plots were prepared and total spots were analysed for 2-fold changes in abundance of protein spot intensities in control and treated gels. Results: In total 517 protein spots were detected; 36 with high significance. Among these 36 spots, 2-fold expression change was analysed in 27 protein spots. Seven spots were upregulated, eight spots were down-regulated, 3 were newly induced and 9 were silenced, while as 9 did not change their abundance 2-fold under salinity. Protein spots (9 in total) which were 2-fold upregulated and newly induced were excised from the respective gels. The spots were tryptically digested and run on LC-MS/MS for generating peptides and performing a comparative fingerprinting of the proteins. The peptide signal data was loaded on the Mascot (Swissprot) database to retrieve protein IDs. Proteins with the best score were selected, namely isomers of oxygen-evolving enhancer protein 1 (S1-S3), RuBisCO (S4), oxygen-evolving enhancer protein 2 (S5), Heat shock protein 70 isomers (S6-S7), RuBisCO activase (S8), rubber elongation factor (S9) and pathogen-related protein 10 (S10). Conclusion: The identified proteins were found to play important roles in photosynthesis, stress response and plant growth.

  A hydroponic experiment was conducted to evaluate and compare the efficiency of Ca and K ions and different maize genotypes with imposed salinity. Two levels of K+ and Ca++ (5 and 10 mM) each were tested on two maize genotypes (Pioneer-3335 and Syngenta-8441) under 100 mM NaCl stress. Saline treatment adversely affected the plant physiological parameters and disturbed the ionic balance and resulted in poor plant growth. However, Syngenta-8441 was more prone to salt stress as compared to Pioneer-3335. Both of the inorganic ions showed significant effects on physiological and ionic components of both genotypes. Among the inorganic ions K was found to be more efficient than Ca in improving the plant growth. Improved physiological and ionic traits were observed more significant with 10 mM K ion treatment followed by 5 mM K. Among Ca treatments higher level of Ca (10 mM) showed more significant results as compared to 5mM Ca++. This study revealed that Ca++ and K+ both are compulsory for maintaining the crop growth because of their mutual effects under salt stress. However, the alleviative efficiency of  K is far better than Calcium but its (Ca++) role could not be neglected, while regarding genotypic differential response imposes the fact that Pioneer-3335 is more tolerant to salinity menace as compared to Syngenta- 8441 but both of the genotypes were significant in their recovery from stress to applied Ca++ and K+.

K Transport

Potassium (K+) is one of the most important cations that plays a significant role in plants and constitutes up to 10% of plants’ dry weight. Plants exhibit complex systems of transporters and channels for the distribution of K+ from soil to numerous parts of plants. In this study, we have identified 39 genes encoding putative K+ transport-related genes in Vigna radiata. Chromosomal mapping of these genes indicated an uneven distribution across eight out of 11 chromosomes. Comparative phylogenetic analysis of different plant species, i.e., V. radiata, Glycine max, Cicer arietinum, Oryza sativa, and Arabidopsis thaliana, showed their strong conservation in different plant species. Evolutionary analysis of these genes suggests that gene duplication is a major route of expansion for this family in V. radiata. Comprehensive promoter analysis identified several abiotic stresses related to cis-elements in the promoter regions of these genes, suggesting their role in abiotic stress tolerance. Our additional analyses indicated that abiotic stresses adversely affected the chlorophyll concentration, carotenoids, catalase, total soluble protein concentration, and the activities of superoxide and peroxidase in V. radiata. It also disturbs the ionic balance by decreasing the uptake of K+ content and increasing the uptake of Na+. Expression analysis from high-throughput sequencing data and quantitative real-time PCR experiments revealed that several K+ transport genes were expressed in different tissues (seed, flower, and pod) and in abiotic stress-responsive manners. A highly significant variation of expression was observed for VrHKT (1.1 and 1.2), VrKAT (1 and 2) VrAKT1.1, VrAKT2, VrSKOR, VrKEA5, VrTPK3, and VrKUP/HAK/KT (4, 5, and 8.1) in response to drought, heat or salinity stress. It reflected their potential roles in plant growth, development, or stress adaptations. The present study gives an in-depth understanding of K+ transport system genes in V. radiata and will serve as a basis for a functional analysis of these genes.
