520 |a Cotton (Gossypium hirsutum) is an important cash crop, providing people with high quality natural fiber. Lignin is the main component of cotton fiber, second only to cellulose. As a main substance filled in the cellulose framework during the secondary wall thickening process, lignin plays a key role in the formation of cotton fiber quality. However, the mechanism behind it is still unclear. In this research, we screened candidate genes involved in lignin biosynthesis based on analysis of cotton genome and transcriptome sequence data. The authenticity of the transcriptome data was verified by qRT-PCR assay. Total 62 genes were identified from nine gene families. In the process, we found the key gene GhCAD7 that affects the biosynthesis of S-lignin and the ratio of syringyl/guaiacyl (S/G). In addition, in combination with the metabolites and transcriptome profiles of the line 0-153 with high fiber quality and the line sGK9708 with low fiber quality during cotton fiber development, we speculate that the ratio of syringyl/guaiacyl (S/G) is inseparable from the quality of cotton fiber. Finally, the S-type lignin synthesis branch may play a more important role in the formation of high-quality fiber. This work provides insights into the synthesis of lignin in cotton and lays the foundation for future research into improving fiber quality
