Transcriptome analysis reveals key immune pathways and metabolites associated with resistance to Verticillium dahliae in GbMBL1.1A-overexpressing cotton.

ABSTRACT: Cotton (Gossypium barbadense L. and Gossypium hirsutum L.), a major economic crop, suffers severe yield losses due to Verticillium wilt caused by Verticillium dahliae Kleb. Although the lectin receptor-like protein GbMBL1.1A has been identified as a key activator of hypersensitive cell death in cotton resistance to this pathogen, its downstream defense mechanisms remain unknown. Here, we performed comparative transcriptome analyses between the GbMBL1.1A-overexpressing (OE) cotton line and its wild-type (WT) recipient counterpart (WC) under both normal (non-infected) and V. dahliae infected conditions. A total of 760 differentially expressed genes (DEGs) were identified by comparing GbMBL1.1A-OE and WT cotton lines under normal condition. Upon pathogen infection across three timepoints, the
