Abstract

Cottonseed is a globally significant oilseed crop due to its high contribution to vegetable oil supply. The process of lipid accumulation is essential for seed maturation and oil buildup. In this study, we analyzed lipid metabolites and gene expression patterns related to fatty acid synthesis in two cotton genotypes with varying oil content. Our lipid analysis identified 588 kinds of lipids in developing embryos of upland cotton, with glycerophospholipids (64.29 %), glycerolipids (17.69 %), and saccharolipids (13.61 %) being the main components. Transcriptome analysis of key genes involved in fatty acid biosynthesis and lipid droplet formation revealed potential regulatory regions influencing lipid content in developing embryos of upland cotton. This research provides valuable insights into the lipidome profiles during embryo development and lays the groundwork for future investigations on lipid accumulation in economically important crops.

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
