Identification of VcRBOH genes in blueberry and functional characterization of VcRBOHF in plant defense.

ABSTRACT: Reactive oxygen species (ROS) serve as signal molecules in plant defense responses, and the respiratory burst oxidase homolog (RBOH) enzyme plays a crucial role in their production. Although numerous RBOH family members have been identified in various plants, little is known about the RBOH genes in blueberries. In this study, we identified six VcRBOH genes from the blueberry genome. Phylogenetic analysis revealed that these VcRBOH genes can be classified into three subgroups. Conserved domain and motif analysis demonstrated high sequence similarity among VcRBOH proteins. Analysis of cis-acting elements suggested that VcRBOH genes may be involved in stress, light, and phytohormone responsiveness. Based on transcriptome data, we observed low expression levels of VcRBOHB, VcRBOHC, and VcRBOHE
