马铃薯SOS基因及其盐胁迫共表达转录因子分析
SOS Gene Family and Their Co-expression Transcription Factor Network under Salt Stress in Solanum tuberosum L
摘要
Abstract
Salt stress impacts plant physiological metabolism through osmotic stress and ion toxicity,and the SOS(Salt Overly Sensitive)signaling pathway plays a critical role in plant resistance to salt stress.In this study,we identified the sequence characteristics of the SOS1,SOS2,and SOS3 proteins in potato(Solanum tuberosum L.)using bioinformatics methods and analyzed their conservation and specificity across different species.Through transcriptomic data analysis,we constructed a co-expres-sion transcription factor network of the SOS1/2/3 genes under salt stress,revealing distinct regulato-ry mechanisms in root and leaf tissues.The results indicate that the SOS1/2/3 gene is co expressed with multiple salt tolerant candidate transcription factors(such as SR1,NF-YA1,TCP20,etc.),sug-gesting that potato salt tolerance depends on a multi-level regulatory network.关键词
