Genome-wide identification and characterization of transcription factors involved in defense responses against Sclerotinia sclerotiorum in Brassica juncea.

ABSTRACT: Sclerotinia sclerotiorum could cause significant yield losses of up to 70% in rapeseed cultivation. Nevertheless, the availability of immune or highly resistant germplasm and mechanisms to combat S. sclerotiorum, particularly in B. juncea, remains insufficient. Transcription factors (TFs) are recognized for their critical role in plant defense against S. sclerotiorum. In the present study, a total of 4807 TFs from 48 families were expressed and identified at 12, 24, and 36 h after inoculation (HAI) in two B. juncea lines: G21-912, exhibiting higher S. sclerotiorum resistance (HR), and G21-853, displaying lower S. sclerotiorum resistance (LR). The number of differentially expressed TFs (DETs) between the HR and the LR lines peaked at 24 HAI, with 202 upregulated and 105 downregulated TFs. T
