Transcriptome Analysis of Short Fiber Mutant Ligon lintless-1 (Li1) Reveals Critical Genes and Key Pathways in Cotton Fiber Elongation and Leaf Development.

ABSTRACT: For efficient spinning and superior fabric production, long fiber length is a desired trait for cotton production. To unveil the molecular basis of the cotton fiber length regulation, a short fiber mutant, Ligon lintless-1 (Li1), is selected to compare with its corresponding wild type (WT). Li1 is a monogenic dominant cotton mutant causing extremely short fibers (<6mm) on mature seeds with visible pleiotropic effects on vegetative growth and development. In this research, we compared the transcriptome of fiber bearing ovules at 1 DPA, 3 DPA, 8 DPA and leaf between Li1 mutant and WT. A total of 7,852 differentially expressed genes (DEGs) were detected in ovules and leaves, which mainly participated in sugar, secondary metabolite and lipid metabolism pathways based on KEGG analysis.
