Genome Wide Identification of Respiratory Burst Oxidase Homolog (Rboh) Genes in Citrus sinensis and Functional Analysis of CsRbohD in Cold Tolerance.

ABSTRACT: Respiratory burst oxidase homologs (Rbohs) are critical enzymes involved in the generation of reactive oxygen species (ROS) that play an important role in plant growth and development as well as various biotic and abiotic stresses in plants. Thus far, there have been few reports on the characterization of the Rboh gene family in Citrus. In this study, seven Rboh genes (CsRbohA~CsRbohG) were identified in the Citrus sinensis genome. The CsRboh proteins were predicted to localize to the cell membrane. Most CsRbohs contained four conserved domains, an EF-hand domain, and a transmembrane region. Phylogenetic analysis demonstrated that the CsRbohs were divided into five groups, suggesting potential distinct functions and evolution. The expression profil
