<i>Gh_FBL43</i> regulates the resistance of <i>Gossypium hirsutum</i> to Verticillium wilt through jasmonic acid and flavonoid-related pathways.

ABSTRACT: F-box-LRR (FBL) genes play crucial roles in the response of plants to pathogen stress. This study involved a systematic analysis of the evolution of the FBL gene family in Gossypium hirsutum from a whole-genome perspective, and through expression pattern analysis combined with virus-induced gene silencing (VIGS), Gh_FBL43 was identified as a gene associated with resistance to Verticillium wilt in G. hirsutum. Further RNA-seq analysis revealed key pathways and genes regulated by Gh_FBL43. The G. hirsutum genome contains 57 FBL genes, which can be divided into five subgroups that were relatively conserved during the evolution of cotton. Expression analysis revealed that the expression level of Gh_FBL43 significantly increased under Verticillium wilt
