FT/TFL Expression Pattern in Male and Female Floral of Vitis amurensis Rupr
To study FT/TFL genes expression pattern in female and male floral of V itis amurensis Rupr.,three male and three female strains were used to study the expression of three FT/TFL genes (VvFT,VvTFL1A and VvTFL1B) by Real-time PCR technology.The three genes expressed not only in female but also in male floral .The relative expression of VvFT gene in female were significantly higher than in male floral ,while the relative expression of VvTFL1A and VvTFL1B genes in male flowers slightly higher than in female floral .The peak value of VvFT gene expression appeared at inflorescence show stage (May 14);while VvTFL1A and VvTFL1B expression appeared one peak value at bud intumescence stage ( April 30 ) .It was suggested that FT genes may be involved in regulation of early flowers,and TFL genes played a role in floral organ development .
