Boosting evidence indicated lipids play important roles in plants. To explore lipid function in cotton fiber development, the lipid composition and content were detected by untargeted and targeted lipidomics. Compared with rapid elongation fibers, the lipid intensity of 16 sub-classes and 56 molecular species decreased, while only 7 sub-classes and 26 molecular species increased in the fibers at the stage of secondary cell wall deposition.

Cotton fibers are extremely elongated single cells, which makes them an ideal model for studying cell development. Here, we used the sphingolipid biosynthesis inhibitor, fumonisin B1 (FB1), and found that it effectively suppressed the myeloblastosis (MYB) transcription factor GhMYB86, thereby negatively affecting fiber elongation.

Sphingosine-1-phophate (S1P) plays a key role in plant resistance to stress, but its specific impact on plant growth and development remains to be fully elucidated. Cotton fiber cells are an ideal material for investigating the growth and maturation of plant cells.
