Genome-wide analysis of the CCT gene family in Liriodendron chinense highlights potential functions in light signaling and chlorophyll biosynthesis.

ABSTRACT:

Background

CCT (CONSTANS, CO-LIKE, and TIMING OF CAB EXPRESSION 1) domain-containing genes play essential roles in regulating photoperiod flowering, circadian rhythms, and environmental adaptation in plants. However, their composition, evolutionary dynamics, and potential functions remain largely unexplored in Liriodendron chinense, an ecologically and economically important relict tree species.

Results

In this study, we conducted a genome-wide identification and characterization of the CCT gene family in L. chinense, identifying 30 LcCCT genes unevenly distributed across 15 chromosomes. Phylogenetic, conserved motif, and gene structure analyses revealed distinct domain architectures among the three major subfamilies (COL, PRR, and CMF), suggesting functional diversification
