Comprehensive Characterization of B-Box Zinc Finger Genes in Citrullus lanatus and Their Response to Hormone and Abiotic Stresses.

ABSTRACT: Plant B-BOX (BBX) zinc finger transcription factors play crucial roles in growth and development and the stress response. Although the BBX family has been characterized in various plants, systematic analysis in watermelon is still lacking. In this study, 25 watermelon ClBBX genes were identified. ClBBXs were grouped into five clades (Clade I, II, III, IV, and V) based on their conserved domains and phylogenetic relationships. Most of the ClBBXs (84%) might be localized in the nuclei or cytoplasm. The classification of ClBBXs was consistent with their gene structures. They were unevenly distributed in nine chromosomes except for Chr4 and Chr10, with the largest number of six members in Chr2. Segmental duplications were the major factor in ClBBX family expansion. Some BBXs</
