Molecular Characterization of FLOWERING LOCUS T-Like Genes of Apple (Malus × domestica Borkh.)

Abstract: The two FLOWERING LOCUS T (FT)-like genes of apple (Malus x domestica Borkh.), MdFT1 and MdFT2, have been isolated and characterized. MdFT1 and MdFT2 were mapped, respectively, on distinct linkage groups (LGs) with partial homoeology, LG 12 and LG 4. The expression pattern of MdFT1 and MdFT2 differed in that MdFT1 was expressed mainly in apical buds of fruit-bearing shoots in the adult phase, with little expression in the juvenile tissues, whereas MdFT2 was expressed mainly in reproductive organs, including fl… Show more

“…Abnormality in the number of floral parts of MdFToverexpressing transgenic apples has been reported previously (Kotoda et al 2010;Tränkner et al 2010;Yamagishi et al 2011). This finding indicated that FT overexpression was able to cause early flowering in apple, but was unable to maintain the induction of floral organ development.…”

“…The two genes are expressed mainly in floral tissues and at different stages of flower development, which suggests that the two genes play different roles in the onset and maturation of apple flowers (Kotoda et al 2010). Transgenic apple plants that express 35S::MdFT1 show early flowering and promotion of flower development within a year after transformation (Kotoda et al 2010;Tränkner et al 2010). Similarly strong promotion of flowering by FT overexpression has been reported for the woody plants poplar, citrus, pear and plum (Endo et al 2005;Hsu et al 2006;Matsuda et al 2009;Srinivasan et al 2012).…”

“…FT homologs have been shown to promote flowering in many perennial species (Endo et al, 2005;Böhlenius et al, 2006;Hsu et al, 2006;Kotoda et al, 2010), but at least in Populus trichocarpa, FT is also involved in the control of growth cessation (Böhlenius et al, 2006). Detailed analyses of two Populus FT paralogs have shown that seasonal changes in their expression control the cycling of reproductive and vegetative growth.…”
