Special Issue Information

Dear Colleagues,

Salt stress, drought stress, high temperatures, and low temperatures are major abiotic stressors that can severely limit plant growth, distribution, and crop yield. The study of plant genetics has major economic impacts: many staple crops are genetically modified to increase yields and provide resistance to stress. Transcription factors have the ability to respond to changes in the external environment by regulating their own expression and employing the spatiotemporal specificity of gene expression to activate target genes. Next-generation sequencing (NGS) technologies accelerate crop improvement methods by enabling the rapid and cost-effective sequencing of entire genomes and transcriptomes.

This Special Issue will address a selection of recent research topics and current review articles in the field of plant genomics and genetics. Bioinformatics papers, up-to-date review articles, and commentaries are also welcome. This Special Issue is supervised by Dr. Hengling Wei and assisted by our Guest Editor's Assistant Editor, Dr. Shoujiang Sun (China Agricultural University, Beijing, China).

Cotton fiber is one of the most important natural fiber sources in the world, and lipid metabolism plays a critical role in its development. However, the specific role of lipid molecules in fiber development and the impact of fatty acid alterations on fiber quality remain largely unknown. In this study, we demonstrate that the downregulation of GhROD1, a gene encoding phosphatidylcholine diacylglycerol cholinephosphotransferase (PDCT), results in an improvement of fiber fineness. We found that GhROD1 downregulation significantly increases the proportion of linoleic acid (18:2) in cotton fibers, which subsequently upregulates genes encoding small heat shock proteins (sHSPs). This, in turn, reduces H2O2 production, thus delaying secondary wall deposition and leading to finer fibers. Our findings reveal how alterations in linoleic acid influence cellulose synthesis and suggest a potential strategy to improve cotton fiber quality by regulating lipid metabolism pathways.
