【摘要】 介绍了植物中MADS-box基因和MADS-box蛋白转录因子的组成,MADS-box基因是一类序列特异的多基因家族,所编码的蛋白即为MADS-box转录因子,它是以二聚体化的形式通过其保守结构域与特定的DNA序列相结合来调控基因的表达.主要介绍了ABC模型及MADS-box基因与花的发育,并介绍了可促进开花的4种MADS-box基因-AGL20、AGL24、CO和SOC1及抑制开花的另外4种MADS-box基因-FLC、FLM、FRI和SVP,最后提出前景和展望.更多还原

【Abstract】 This article introuduced the constitutes of the MADS box gene and the MADS box transcriptional factor in the plants,the MADS box gene is a regulatory gene family and the encoded protein is a transcription factor,which combined with specific DNA sequences by its conservative sequence in the form of dimer to regulate the expression of gene.Maily introduced the model of ABC and the effect of MADS box gene to the development of flower,and listed 4 kinds of MADS box genes AGL20、AGL24、CO and SOC1,which could improve flower;and another 4 kinds of MADS box gene FLC、FLM、FRI and SVP,which could repress flower.In the final of the article made some expectations.更多还原
