摘要

Fusarium wilt in cabbage, caused by Fusarium oxysporum f. sp. conglutinans (Foc), was investigated through early-stage transcriptome profiling of two susceptible cultivars exhibiting distinct rates of disease progression. At 3 days post-inoculation, 119 commonly regulated genes were identified, with upregulated genes including those involved in cell wall remodeling (e.g., PAE9, XTHs) and downregulated genes including key immune regulators such as NIA1, BIK1, and CIPK9. qRT-PCR confirmed these patterns. These early transcriptional responses may reflect Foc-mediated suppression of basal defenses and offer candidate markers for resistance breeding in cabbage via marker-assisted selection strategies.
