Comparative Studies among Different Genotypes of Soybean (Glycine max L.) against Salinity Stress

Abstract

Soybean (Glycine max L.) is a significant legume of food and plays a vital role in human livelihood. It is rich in proteins (40%), which contain major essential amino acids, and edible oil (20%). Salinity stress affects soybean yield 30-80%. Salinity stress significantly reduces net photosynthetic rates, increases energy losses for the mechanism of salt exclusion, substantially decreases nutrient intake and ultimately results in reduced plant growth. Present investigation was conducted to show how morphological and biochemical changes occur due to the stress of salinity on the soybean plant genotypes. Stress with salinity resulted in increased protein and proline content to withstand stress with salinity. Better root length, shoot length fresh weight and dry weight were observed of JS-355 variety. The JS-355 variety demonstrated the better response to all concentrations of salt stress used from 40 mM to 280 mM. As the salt concentration increases, so does the protein and proline concentration. The JS-355 variety showed the better results at all salt concentrations. The highest protein and proline content at high salt concentration was observed in varietyJS-355.

Viral delivery of CRISPR/Cas9 genome editing for rapid crop improvement: A promising approach to enhance crop resilience against biotic and abiotic stresses

“…Enhanced abiotic stress tolerance is another essential area where viral delivery of CRISPR/Cas9 has shown great promise in improving crop resilience. Abiotic stresses, such as drought, salinity, extreme temperatures, and nutrient deficiencies, pose significant challenges to agricultural productivity worldwide (Pawar et al, 2020;Siddiki et al, 2020) [87,109] . By leveraging the precision and efficiency of CRISPR/Cas9 technology delivered through viral vectors, researchers have made significant strides in developing crops with increased tolerance to these adverse environmental conditions.…”

“…For example, the Cas13a protein has been incorporated, allowing for precise epigenome editing in plants (Dreissig et al, 2017) [36] . Additionally, the use of RNA viruses as delivery systems for CRISPR/Cas9 components has demonstrated great potential in achieving heritable gene editing in wheat, maize, and other crops (Uranga et al, 2023) [109] ; (Beernink et al, 2022) [14] ; (Begum et al, 2019) [15] . This viral delivery system for CRISPR/Cas9 has also been harnessed for targeted gene activation (K. Chen et al, 2019; Sasse et al, 2019) [94] and targeted DNA demethylation (Ghoshal et al, 2020) [44] , further expanding its applications in plant research.…”

Ameliorating effect of nanoparticles and seeds’ heat pre-treatment on soybean plants exposed to sea water salinity

“…Therefore, new strategies should be developed to counteract the negative impact of salinity on the agriculture. Soybean ( Glycine max L.) is an important crop for human nutrition and animal feeds because of its seeds contain about 40 % protein and 20 % edible oil as well as 30 % carbohydrates including 10 % of total sugar [ 3 ]. The global demand for soybean is ever increasing as it is used as input for numerous industries [ 4 ].…”
