Gene network of oil accumulation reveals expression profiles in developing embryos and fatty acid composition in Upland cotton

Cotton is widely cultivated in temperate regions across the world and is often constrained by a short planting window that is bookended by low, suboptimal temperatures. With the growing interest in early season planting, improvements in the cold germination ability of cotton will be necessary to ensure the production stability of early planted crops. The importance of saturation levels of membrane and storage lipids in enhancing cold tolerance in plants, as well as improving cold germination ability in seeds have been widely researched in a range of plant species. While studies have shown that higher levels of unsaturated lipids can enhance cold germination ability and reduce seedling injury in other crops, similar efforts have been fairly limited in cotton. This review looks at the functional properties of membrane and storage lipids, and their role in membrane stability and reorganization during the early stages of germination. Additionally, the importance of storage lipid composition as an energy source to the growing embryo is described in the context of cellular energetics (i.e., fatty acid catabolism). Finally, perspectives in improving the cold germination of upland cotton by manipulating the fatty acid composition of both membrane and storage lipid content of seeds are presented.

Abstract Nitric oxide (NO) is a key signaling molecule regulating several plant developmental and stress responses. Here, we report that NO plays an important role in seed oil content and fatty acid composition. RNAi silencing of Arabidopsis S-nitrosoglutathione reductase 1 (GSNOR1) led to reduced seed oil content. In contrast, nitrate reductase double mutant nia1nia2 had increased seed oil content, compared with wild-type plants. Moreover, the concentrations of palmitic acid (C16:0), linoleic acid (C18:2), and linolenic acid (C18:3) were higher, whereas those of stearic acid (C18:0), oleic acid (C18:1), and arachidonic acid (C20:1) were lower, in seeds of GSNOR1 RNAi lines. Similar results were obtained with rapeseed embryos cultured in vitro with the NO donor sodium nitroprusside (SNP), and the NO inhibitor NG-Nitro-L-arginine Methyl Ester (L-NAME). Compared with non-treated embryos, the oil content decreased in SNP-treated embryos, and increased in L-NAME-treated embryos. Relative concentrations of C16:0, C18:2 and C18:3 were higher, whereas C18:1 concentration decreased in rapeseed embryos treated with SNP. Proteomics and transcriptome analysis revealed that three S-nitrosated proteins and some key genes involved in oil synthesis, were differentially regulated in SNP-treated embryos. Therefore, regulating NO content could be a novel approach to increasing seed oil content in cultivated oil crops.
