【摘要】 成花是植物生活周期中的最重要事件之一,受外部环境和内部因素的调节,植物体内一系列基因参与对成花的调控。FT基因是调节植物成花的重要基因之一,编码约含175氨基酸残基的小分子量蛋白,称为成花素。FT蛋白的序列及结构在不同植物种之间具有较高的保守性,其主要功能是调节植物成花。本文主要对近年来国内外分离的FT基因及其功能进行了总结,并对FT基因表达调控机制和FT蛋白调控植物成花的分子机制进行综述,以期为植物成花机制的深入研究提供一些参考。更多还原

【Abstract】 Flowering, which regulated by external environmental and endogenous factors, is one of the most important evidences in the life cycle of higher plant. A set of genes including FT participates in the regulation on flowering. FT encodes a small protein, which is named florigen consisting of 175 amino acids. FT proteins are considerable conservative in consequence and structure among higher plants and its main function is promoting flowering. Genes, which isolated from higher plants in recent years, and its functions were summarized in this review. Providing some reference for thorough research on flowering mechanism, the latest progress in the molecule mechanism, of which FT gene expression regulation and flowering regulation of FT protein, was presented in the paper.更多还原
