Over-expression of EjLFY-1 Leads to an Early Flowering Habit in Strawberry (Fragaria × ananassa) and Its Asexual Progeny.

ABSTRACT: As a master regulator involved in flower development, LEAFY-like gene has been demonstrated to play a key role in the flowering process regulation of angiosperms. Expression analysis of EjLFY-1, a LEAFY (LFY) homolog of loquat (Eriobotrya japonica Lindl.), indicated its participation in the regulation of flowering in loquat. To verify its function and potential value in the genetic engineering to shorten the juvenile phase, ectopic expression of EjLFY-1 in strawberry (Fragaria × ananassa) was achieved using Agrobacterium-mediated gene transfer of a plant expression vector with the loquat EjLFY-1 gene driven by the CaMV 35S promoter. Totally 59 plantlets were verified to be the transformants. The presence, expression and
