摘要
MADS-box是植物体内一种重要的转录因子,其家族成员具有典型的MIKC结构、高度保守的N端MADS以及保守性较低的I域和C端.MADS-box基因广泛表达于植物的根、茎、叶、花、芽等组织部位,并参与调控花期、花器官发育、种子发育及非生物胁迫响应等过程.近年来的研究报道显示,不同MADS-box基因的表达模式不尽相同,其功能也存在较大差异.本文概述了大豆MADS-box基因家族的结构及分类,总结了大豆MADS-box基因家族花发育ABCDE模型中相关成员及SVP1 SOC1、FLC等基因的研究进展.最后对大豆MADS-box的研究提出了展望,为今后进一步挖掘和利用该类转录因子基因进行大豆遗传改良和种质创新提供参考依据.
Abstract
MADS-box is an important transcription factor in plants,and its family members have a typical MIKC structure,highly conserved N-terminal MADS,and less conserved I domains and C-terminals.MADS-box genes are widely expressed in the roots,stems,leaves,flowers,buds and other trophic tissue parts of plants,and are involved in regulating the flowering time,flower development,seed development and abiotic stress response.In recent years,researches have shown that the expression patterns of different MADS-box genes are distinct,and their functions are also quite different.This review introduces the structure and classification of soybean MADS-box gene family,and summarizes the research progress of related members of MADS-box genes in ABCDE model,such as SVP,SOC1,FLC and other genes in the flower development.Finally,the research on soybean MADS-box is prospected,which provides an essential information for further utilization of such transcription factor genes for soybean genetic improvement and germplasm innovation in the future.
