Genome-wide identification of SABATH gene family in soybean relate to salt, aluminum, chromium toxicity

Le résumé fourni par la source

SABATH gene family in plants participates in metabolic processes such as methylation of various hormones and plays an essential role in plant response to abiotic stress. In this study, we identified and sequenced 28 SABATH genes in soybean and divided them into three groups. Genome mapping annotation suggested that tandem repeat was the cause of SABATH gene amplification in soybean. Phylogenetic and homology analyses show that the three groups may have originated from different ancestors. Transcriptome analysis was performed in six soybean tissues using data from public transcriptome. In addition, transcriptome and gene expression analyses revealed their expression patterns under different soybean varieties and various abiotic stresses. These results reveal the differential expression of GmSABATHs gene under these stresses, indicating their potential role in the mechanism of soybean adapting to environmental challenges. These results provide reference information for the evolutionary study of the SABATH family and the potential role of GmSABATHs in soybean resistance to abiotic stress.
