菊花GT-2型Trihelix转录因子参与低温诱导成花的机制解析

菊花等花卉产品消费具有时令性特点，通过精准花期调控以实现应时供应是确保花卉产品生产效益的关键。因此，成花转化一直是菊花乃至花卉领域的研究热点。我们的前期工作发现：GT-2型Trihelix转录因子基因受低温诱导表达，参与了菊花成花转化。本项目拟通过对GT-2型Trihelix转录因子调控成花功能的遗传学和表观遗传学分析，解析GT-2型Trihelix转录因子参与低温诱导菊花成花的作用机制。本项目的实施，有望为阐明低温诱导菊花成花的分子机制提供新的认知，也为节能型精准调控花期的菊花周年生产提供理论依据。

The consumption of chrysanthemum has the characteristics of timeliness. The key to ensure the production efficiency of chrysanthemum flowers is to realize timely supply through precise regulation of flowering time. Therefore, research about flowering time is an important aspect in the field of ornamental horticulture. Our preliminary work found that a gene encoding GT-2 type Trihelix transcription factor can be induced by low temperature in chrysanthemum, and the function analysis indicated the gene is involved in flowering time of chrysanthemum. In this study, we aim to investigate the involvement mechanism of GT-2 type Trihelix transcription factor in low temperature induction of flowering in chrysanthemum, through genetic and epigenetic analyses of the function of GT-2 Trihelix transcription factor in regulation of flowering in chrysanthemum. Our results will be valuable for understanding the mechanism of flowering in response to low temperature, and will provide a theoretical basis for the precise regulation of the annual production of flowering in chrysanthemum.
