Genome-Wide Identification and Expression Analyses of CONSTANS-Like Family Genes in Cucumber (Cucumis sativus L.)

Abstract The CONSTANS - like ( COL ) gene family is one of the plant-specific transcription factor families that play important roles in plant growth and development. However, knowledge COLs related cucumber limited, their biological functions, especially photoperiod-dependent flowering process, are still unclear. In this study, twelve CsaCOL genes were identified genome. Phylogenetic conserved motif analyses provided insights into evolutionary relationship between CsaCOLs . Further, comparative genome analysis revealed different species, collinearity pairs to CsaCOL5 Ten kinds cis-acting elements vividly detected promoter regions, including five light-responsive elements, which echo diurnal rhythm expression patterns seven under SD LD photoperiod regimes. Combined with data developmental stage, three involved network pivotal for floral induction process. Our results provide useful information further elucidating structural characteristics, patterns, functions many plants
