Abstract
Cotton is a globally important fiber crop that faces significant yield losses due to Verticillium wilt caused by Verticillium dahliae. Short-chain dehydrogenase/reductases (SDRs) are NAD(P)(H)-dependent enzymes involved in metabolic pathways and stress responses, but their role in disease resistance is not well understood in cotton. The objective of this study was to investigate the function of GhSDR500 in cotton defense against V. dahliae. A combination of population genetics, pangenome analysis, gene expression profiling, transcription factor binding analysis, and functional validation through Virus-Induced Gene Silencing (VIGS) was employed. Population genetic analysis revealed a favorable GhSDR500 allele selected during cotton domestication. A G > C mutation causing a glycine-to-alanine substitution in the NAD domain was identified, with the G allele strongly favored in modern cultivars due to its association with enhanced resistance. Pangenome analysis further highlighted presence–absence variations and transposable elements around GhSDR500. Expression studies showed strong upregulation of GhSDR500 in resistant cotton varieties during early infection stages. VIGS confirmed its role in disease resistance, as silencing GhSDR500 increased susceptibility to V. dahliae and reduced expression of pathogenesis-related genes. Transcription factor binding analysis identified WRKY genes as key regulators. These results demonstrate that GhSDR500 plays a key role in resistance to V. dahliae and represents a potential target for breeding Verticillium wilt-resistant cotton varieties.
期刊介绍:
The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues.
Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and:
Lack of water (drought) and excess (flooding),
Salinity stress,
Elevated temperature and/or low temperature (chilling and freezing),
Hypoxia and/or anoxia,
Mineral nutrient excess and/or deficiency,
Heavy metals and/or metalloids,
Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection,
Viral, phytoplasma, bacterial and fungal plant-pathogen interactions.
The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
