摘要
CO is an important regulator of photoperiodic response and flowering. However, the biological functions of CO and COL genes in tomato (Solanum lycopersicum) remain elusive. Here we identified 13 members in CO/COL family from the tomato genome. They were divided into three groups, and each group had specific characteristics in gene structures and protein domains. The SlCO/SlCOL genes showed different tissue-specific expression patterns and circadian rhythms, indicating their functional diversity in tomato. Moreover, among 13 members, the expression of SlCOL, SlCOL4a, and SlCOL4b was negatively correlated with flowering time variation in ten tomato lines. Through interaction network prediction, we found three FLOWERING LOCUS T (FT) orthologs, SINGLE FLOWER TRUSS (SFT), FT-like (FTL), and FT-like 1 (FTL1), which functioned as candidate interactors of SlCOL, SlCOL4a, and SlCOL4b. Further expression analyses suggested that SFT coincided with the three SlCOL genes in ten tomato lines with varied flowering time. These findings implied that SlCOL, SlCOL4a, and SlCOL4b are potential flowering inducers in tomato, and SFT may act as their downstream target. Thus, our study built a foundation for understanding the precise roles of SlCO/SlCOL family in plant growth and development of tomato, especially in flowering.
