FT homologs are crucial for the flowering process, playing a vital role as 'florigens' in plants. In this study, we isolated and characterized an FT homolog, FaFT1, from cultivated strawberry. Nucleotide sequence analysis revealed a 531-bp open reading frame in FaFT1, encoding a putative protein with typical DPDxP and GxHR motifs belonging to the PEBP family proteins. For vegetative tissues or organs, qRT-PCR revealed that FaFT1 was primarily expressed in leaves. Notably high expression levels were detected in flowers and fruits, including the pith and cortex of the receptacle. Analysis of potential putative cis-acting regulatory elements (CREs) in this gene promoter indicated that many of them are associated with plant hormonal responses and abiotic stress responses. Expression detection confirmed that GA3 treatment enhanced the expression of FaFT1. When ectopically expressed in Arabidopsis, FaFT1 could promote the flowering process under SD conditions. These results suggested the possible role of FaFT1 in the regulation of reproductive development in cultivated strawberry. [ABSTRACT FROM AUTHOR] |
