Identification of new loci for salt tolerance in soybean by high-resolution genome-wide association mapping

Abstract: Background Salinity is an abiotic stress that negatively affects soybean [ Glycine max (L.) Merr.] seed yield. Although a major gene for salt tolerance was identified and consistently mapped to chromosome (Chr.) 3 by linkage mapping studies, it does not fully explain genetic variability for tolerance in soybean germplasm. In this study, a genome-wide association study (GWAS) was performed to map genomic regions for salt tolerance in a diverse panel of 305 soybean accessi… Show more

“…In this context, QTL mapping and GWASs provide a suitable opportunity to identify genes responsible for quantitative trait variation such as salt tolerance. In this regard, genetic factors associated with salt stress have been previously investigated in several crops, such as rice [ 41 , 196 , 197 ], barley [ 198 , 199 ], wheat [ 200 , 201 ], chickpea [ 202 ], sesame [ 203 ], cotton [ 204 , 205 ], and soybean [ 206 ].…”

“…The edit(s) can be made in the actual gene, and hence, there are no position or dosage effects. Gene expression can be totally knocked out, which has previously been difficult using RNAi approaches, which usually lead to a diminution of gene expression but rarely to zero (Eamens et al, 2008). This also means that editing of candidate genes enables clear identification of single gene action.…”

“…Interestingly, the most significant SNP related to LSS was pinpointed in GmCHX1 gene, which explained 63% variation of the phenotype (Patil et al ., 2016). Likewise, GWAS of 234 lines elucidated genomic architecture of salinity tolerance in soybean with significant MTAs for leaf scorch score, chlorophyll content ratio, leaf sodium content and leaf chloride content (Do et al ., 2019).…”

“…Overexpression of fatty acid desaturases (FAD3 and FAD7) enhanced tolerance to cold stress in tomato (Dominguez et al ., 2010). In recent years, some novel genes/transcription factors have been characterized for modulating stress responsive genes associated with abiotic stress tolerance by genome-wide characterization (Li et al ., 2019;Do et al , 2019). Efforts have also been made to enhance abiotic stress tolerance in soybean by manipulating expression of several genes/transcription factors (Jumrani & Bhatia., 2019;Zhanget al ., 2019;Chen et al , 2019).…”
