Comparative transcriptome analysis reveals evolutionary divergence and shared network of cold and salt stress response in diploid D-genome cotton.

ABSTRACT:

Background

Wild species of cotton are excellent resistance to abiotic stress. Diploid D-genome cotton showed abundant phenotypic diversity and was the putative donor species of allotetraploid cotton which produce the largest textile natural fiber.

Results

A total of 41,053 genes were expressed in all samples by mapping RNA-seq Illumina reads of G. thurberi (D₁), G. klotzschianum (D_3-k), G. raimondii (D₅) and G. trilobum (D₈) to reference genome. The numbers of differently expressed genes (DEGs) were significantly higher under cold stress than salt stress. However, 34.1% DEGs under salt stress were overlapped with cold stress in four species. Notably, a potential shared network (cold and salt response, including 16 genes) was mined
