摘要
为揭示棉花耐盐分子机制,筛选出棉花盐胁迫应答相关基因.文章从4个新疆主栽棉花品种中筛选得到一个对盐胁迫具有强耐受性的‘新陆中69号’,并在盐胁迫下对棉花根系进行了转录组分析.结果表明:有891个基因表达量上调,666个基因表达量下调;GO富集分析结果表明:差异表达基因数量较多的主要集中在分子功能、细胞组分、生物学过程中;KEGG分析结果表明:差异表达基因主要参与木质素生物合成和植物MAPK信号通路.
Cotton is one of the most important economic crops in China,especially in Xinjiang.However,in the process of cotton production,it is often subject to salinity stress,which is an important environmental limiting factor,for the growth and development of cotton.A cotton cultivar named xinluzhong No.69,with strong tolerance to salt stress,was screened from 4 main cotton cultivars in Xinjiang,to reveal the molecular mechanism of cotton salt tolerance.The results of transcriptome analysis showed that 891 genes were up-regulated and 666 genes were down-regulated in cotton roots.The results of GO enrichment analysis showed that the majority of differentially expressed genes were concentrated in molecular functions,cellular components and biological processes.KEGG analysis showed that the differentially expressed genes were mainly involved in lignin biosynthesis and plant MAPK signaling pathway.
