AI Article Synopsis
- - The cotton industry faces a significant threat due to a decline in yield and quality caused by infection; however, the mechanisms behind cotton's resistance to this infection are not well understood, hindering the development of resistant cultivars.
- - Researchers studied two upland cotton cultivars (resistant JK1775 and susceptible Z8) using transcriptome sequencing to analyze their defense responses at different stages of infection, discovering that JK1775 displayed a higher number of differentially expressed genes (DEGs) compared to Z8.
- - The study found that both cultivars had DEGs enriched in the MAPK signaling pathway and the phenylpropanoid metabolic pathway, indicating that certain genes involved in lignin and coumarin biosynthesis
Article Abstract
Introduction: causes a serious decline in cotton yield and quality, posing a serious threat to the cotton industry. However, the mechanism of resistance to in cotton is still unclear, which limits the breeding of resistant cultivars.
Methods: To analyze the defense mechanisms of cotton in response to infection, we compared the defense responses of two upland cotton cultivars from Xinjiang (JK1775, resistant; Z8,susceptible) using transcriptome sequencing at different infection stages.
Results: The results revealed a significant differential expression of genes in the two cotton cultivars post infection, with the number of DEGs in JK1775 being higher than that in Z8 at different infection stages of . Interestingly, the DEGs of both JK1775 and Z8 were enriched in the MAPK signaling pathway in the early and late stages of infection. Importantly, the upregulated DEGs in both cultivars were significantly enriched in all stages of the phenylpropanoid metabolic pathway. Some of these DEGs were involved in the regulation of lignin and coumarin biosynthesis, which may be one of the key factors contributing to the resistance of upland cotton cultivars to in Xinjiang. Lignin staining experiments further showed that the lignin content increased in both resistant and susceptible varieties after inoculation with .
Discussion: This study not only provides insights into the molecular mechanisms of resistance to Verticillium wilt in Xinjiang upland cotton but also offers important candidate gene resources for molecular breeding of resistance to Verticillium wilt in cotton.

Cotton GhMAX2 positively regulates fiber elongation by mediating the degradation of GhS1FA, which transcriptionally represses GhKCS9 expression. Strigolactones (SLs) are known to promote cotton fiber development. However, the precise molecular relationship between SL signaling and fiber cell elongation remains unclear.

Cotton leaf curl disease (CLCuD) is a major constraint for production of cotton (Gossypium sp.) in Northwest India. CLCuD is caused by a monopartite, circular ssDNA virus belonging to the genus Begomovirus in association with betasatellites and alphasatellites, and ttransmitted by a whitefly vector (Bemisia tabaci).

Background: Drought stress is a significant global challenge that negatively impacts cotton fiber yield and quality. Although many drought-stress responsive genes have been identified in cotton species (Gossypium spp.), the diversity of drought response mechanisms across cotton species remains largely unexplored.

Debate over resistance management tactics for genetically engineered (GE) crops expressing insecticidal toxins is not new. For several decades, researchers, regulators, and agricultural industry scientists have developed strategies to limit the evolution of resistance in populations of lepidopteran and coleopteran pests. A key attribute of many of these events was insecticide resistance management (IRM) strategies designed around a presumed high-dose expression sufficient to kill 99.
