Possible involvement of locus-specific methylation on expression regulation of leafy homologous gene (CiLFY) during precocious trifoliate orange phase change process.

ABSTRACT: DNA methylation plays an essential role in regulating plant development. Here, we described an early flowering trifoliate orange (precocious trifoliate orange, Poncirus trifoliata L. Raf) was treated with 5-azacytidine and displayed a number of phenotypic and developmental abnormalities. These observations suggested that DNA methylation might play an important role in regulating many developmental pathways including early flowering trait, and then the expression level of five key or integrated citrus flowering genes were analyzed. Our results showed that flowering locus T (CiFT) relative expression level was increased with the increasing concentrations of 5-AzaC. However, leafy (CiLFY), APETELA1 (CiAP1), terminal flower1 (CiTFL1), and flowering locus C (CiFLC) showed highest relative expre
