Comparative Transcriptomic Analysis Reveals the Molecular Responses in Two Contrasting Hazelnut Varieties against Botrytis cinerea Infection

Botrytis cinerea, a pathogenic fungus that causes necrosis in plants, is one of the most destructive pathogens hazelnuts. This responsible for causing Husk Brown Rot, significant threat to hazelnut production. The plant’s defense mechanism against this pathogen, as well other pathogens, complex biological process involves changes at molecular, biochemical, and physiological levels. To better understand molecular responses plants B. cinerea infection, we conducted comparative transcriptome profiling study between cinerea-resistant Ping’ou hybrid variety (Dawei; DW) susceptible (Qiuxiang; QX). Our focused on profiles DW QX after three days infection. results our showed moderate strategies both response Specifically, observed expression 14 disease-resistant genes was significantly different QX. analysis revealed had higher number immunity-related differentially expressed compared QX, which indicates these play crucial role inducing innate resistance highlights plant like controlled by multiple pathways, each playing specific role. findings provide new insights into development varieties are resistant By using candidate identified study, it may be possible enhance reduce impact Rot
