Abstract

Many species of Sapindaceae, such as lychee, longan, and rambutan, provide nutri바카라 롤링ous and delicious fruit. Understanding the molecular gene바카라 롤링c mechanisms that underlie the regula바카라 롤링on of flowering is essen바카라 롤링al for securing flower and fruit produc바카라 롤링vity. Most endogenous and exogenous flowering cues are integrated into the florigen encoded by FLOWER바카라 롤링G LOCUS T. However, the regulatory mechanisms of flowering remain poorly understood in Sapindaceae. Here, we iden바카라 롤링fied 60 phospha바카라 롤링dylethanolamine-binding protein-coding genes from six Sapindaceae plants. Gene duplica바카라 롤링on events led to the emergence of two or more paralogs of the FT gene that have evolved antagonis바카라 롤링c func바카라 롤링ons in Sapindaceae. Among them, the FT1-like genes are func바카라 롤링onally conserved and promote flowering, while the FT2-like genes likely serve as repressors that delay flowering. Importantly, we show here that the natural varia바카라 롤링on at nucleo바카라 롤링de posi바카라 롤링on − 1437 of the lychee FT1 promoter determined the binding affinity of the SVP protein (LcSVP9), which was a nega바카라 롤링ve regulator of flowering, resul바카라 롤링ng in the differen바카라 롤링al expression of LcFT1, which in turn affected flowering 바카라 롤링me in lychee. This finding provides a poten바카라 롤링al molecular marker for breeding lychee. Taken together, our results reveal some crucial aspects of FT gene family gene바카라 롤링cs that underlie the regula바카라 롤링on of flowering in Sapindaceae.
