摘要
开花是高等植物从营养生长向生殖生长转变的过程,该过程受到众多基因的调控,涉及6个开花信号途径。其中,FLOWERING LOCUS T(FT)基因是一个非常关键的成花整合因子,该基因也被证实在柑橘中具有促进开花的功能。本文结合近年来国内外有关柑橘FT同源基因的研究,从4个方面进行了综述:柑橘不同属间FT同源基因克隆鉴定情况;柑橘FT同源基因在不同组织及季节的表达分析差异;柑橘FT同源基因在促进开花功能上的研究现状;影响FT基因表达的环境条件。并对今后有待解决的问题及研究方向进行展望。
Flowering is the transition stage from vegetative growth to reproductive growth in higher plants,which is regulated by multiple genes and involves six flowering signal pathways.Among them,FT gene is a key floral integrator and a citrus orthologue FT has been confirmed to promote flowering in citrus. Combined with the latest researches,four aspects are reviewed in this paper： cloning identification of FT gene in different species of citrus; expression analysis of citrus orthologue FT gene in different tissues and seasons; research status on the function of promoting flowering by citrus orthologue FT gene; environmental conditions affecting the expression of citrus orthologue FT gene.Finally,several unsolved problems and research interests are listed for future studies.
