Genome-Wide Identification and Characterization of the Abiotic-Stress-Responsive LACS Gene Family in Soybean (Glycine max)

Long-chain acyl-CoA synthases (LACSs) are a key factor in the formation of after fatty acid hydrolysis and play an important role plant stress resistance. This gene family has not been research soybeans. In this study, soybean (Glycine max (L.) Merr.) whole genome was identified, LACS genes were screened, bioinformatics, tissue expression, abiotic stress, drought co-expression transcription factors analyzed to preliminarily clarify function soybean. A total 17 screened from sequencing data. bioinformatics analysis GmLACS carried out aspects phylogeny, structure, conserved sequence promoter homeopathic element. The spectra GmLACSs different organs stresses used by qRT-PCR. genes, which co-expresses significant response factors. results showed that all have highly AMP-binding domains, divided into 6 subfamilies. Transcriptome indicated gene-encoding expression profiles under alkali, low temperature, stress. GmLACS9/15/17 significantly upregulated temperature Co-expression there close correlation between responded These provide theoretical empirical basis for clarifying mechanism
