“…But the maximum RDSTI value was recorded in T 2 V 5 (95.78%) and T 2 V 4 had lowest RFSTI (71.22%) followed by T 2 V 6 (72.26%). These results are agreement with Dafalla et al, (2014); Kafi et al, (2013); Farooq et al, (2015); Queiroz et al, (2012).…”

An experiment was conducted at the growth chamber of Department of Crop Botany in the Bangladesh Agricultural University, Mymensingh, Bangladesh during March 2018 to observe morpho-physiology and anatomical response of sorghum. Six genotypes were grown in hydroponics with a full nutrient solution (NH4NO3-500 μM; Ca(NO3)2-500 μM; MgSO4-200 μM; KH2P04 -100 μM; FeC13-2μM; H2B03-11 μM; MnC12-2μM; ZnC12-0.35μM; CuCl2-0.2μM; (NH4)6Mo704-0.1 μM) and 100 mM salinity was imposed on 14 days seedlings. Data on morpho-physiological and anatomical parameters from seedlings were collected after 21 days and stress tolerant indexes of shoot and root were analyzed. Anatomical parameters like metaxylem and protoxylem thickness were also investigated. The results indicated that all the parameters viz. root length, shoot length, fresh and dry weight of shoot and root, stress tolerance index of root, and shoot, dry weight of shoot and root, relative chlorophyll content, photochemical efficiency (Fv/Fm), proline concentration, total root area, vascular cylinder area and root diameter were decreased with increasing salinity levels except leaf proline content. Genotypes BD 750 and BD 686 showed better performance considering tolerant indicators while the poor performance was exhibited by BD 747 and BD 753. Thus, based on overall observation BD 750 and BD 686 might be salt tolerant. The Agriculturists 2019; 17(1-2) 52-65

“…The Clion competes with nitrate for the binding site of the transporter. So to overcome the nitrate deficiency, PAL enzymes activate and convert the accumulated amino acid L-phenylalanine to ammonia [71]. The PAL also induces their upregulation in oxidative stress.…”

Halotolerant rhizobacteria Pseudomonas pseudoalcaligenes and Bacillus subtilis mediate systemic tolerance in hydroponically grown soybean (Glycine max L.) against salinity stress

et al. 2020

Salt stress is one of the devastating factors that hampers growth and productivity of soybean. Use of Pseudomonas pseudoalcaligenes to improve salt tolerance in soybean has not been thoroughly explored yet. Therefore, we observed the response of hydroponically grown soybean plants, inoculated with halotolerant P. pseudoalcaligenes (SRM-16) and Bacillus subtilis (SRM-3) under salt stress. In vitro testing of 44 bacterial isolates revealed that four isolates showed high salt tolerance. Among them, B. subtilis and P. pseudoalcaligenes showed ACC deaminase activity, siderophore and indole acetic acid (IAA) production and were selected for the current study. We determined that 10 6 cells/mL of B. subtilis and P. pseudoalcaligenes was sufficient to induce tolerance in soybean against salinity stress (100 mM NaCl) in hydroponics by enhancing plant biomass, relative water content and osmolytes. Upon exposure of salinity stress, P. pseudoalcaligenes inoculated soybean plants showed tolerance by the increased activities of defense related system such as ion transport, antioxidant enzymes, proline and MDA content in shoots and roots. The Na + concentration in the soybean plants was increased in the salt stress; while, bacterial priming significantly reduced the Na + concentration in the salt stressed soybean plants. However, the antagonistic results were observed for K + concentration. Additionally, soybean primed with P. pseudoalcaligenes and exposed to 100 mM NaCl showed a new protein band of 28 kDa suggesting that P. pseudoalcaligenes effectively reduced salt stress. Our results showed that salinity tolerance was more pronounced in P. pseudoalcaligenes as compared to B. subtilis. However, a detailed study at molecular level to interpret the mechanism by which P. pseudoalcaligenes alleviates salt stress in soybean plants need to be explored.

“…Moreover, EBL seed soaking recovered the contents of these elements under IMI toxicity. Amino acids like GABA and proline are supposed to be involved in increasing the resistance of plants under abiotic stress conditions (Queiroz et al 2012;Sharma et al 2015). Glycine, cysteine and phenylalanine are involved in triggering the antioxidative system of plants, as these amino acids also act as signaling molecules (Teixeira et al 2017).…”

“…Glycine, cysteine and phenylalanine are involved in triggering the antioxidative system of plants, as these amino acids also act as signaling molecules (Teixeira et al 2017). Moreover, the accumulation of other amino acids like arginine, alanine, tyrosine, isoleucine, serine, glutamine, histidine and valine were also related to the enhanced resistance of Glycine max plants subjected to salt stress (Queiroz et al 2012). Data are Mean ± SD (n = 3), Two-way ANOVA, Tukey's test.…”

Pesticides are applied to protect crops from a variety of insect pests but their application cause toxicity to plants that results, among others, in reduction of protein as well as amino acid contents. The present study is aimed at observing the effect of seed pre-soaking with 24-epibrassinolide (EBL) on the protein and amino acid content in the leaves of Brassica juncea L. grown in soil that is amended with pesticide imidacloprid (IMI). Soil amendment with IMI resulted in a decrease in the contents in leaves of total proteins and 21 amino acids studied. Seed soaking with 100 nM of EBL resulted in the recovery of total protein as well as amino acid contents in leaves, when compared with plants grown in only IMI amended soils.

Effect of salt on the growth and metabolism of Glycine max

Abstract: Ala and Gaba (via Glu) in the roots while the increase in Pro and Gaba could be related to the adaptation of the plant to salinity.
