Phylogenetic tree, gene domain, and structure analysis of VvRCHCs in grapevine. a The phylogenetic tree of VvRCHCs was constructed using the ML method. Different background colors represent different grouping branches. b Domain analysis of VvRCHCs proteins. At the bottom of the line, different colored squares represent different types of conserved amino acid sequences and based on MEME analysis. The modules of different colors above the line represent the functional domains that have been identified. c Genetic structure of VvRCHCs, the CDS sequence is represented by a blue square/rectangle, the introns by black lines
