摘要: 被子植物花瓣锥形表皮细胞赋予花瓣特有的生物学功能,它直接影响到花瓣表面的颜色、气味、温度、湿度、光学作用等,从而优化花瓣与授粉者的特异性互作。Mixta基因直接决定了花瓣锥形表皮细胞的形成。Mixta编码一个MYB类转录因子,来源于金鱼草花瓣锥形表皮细胞;AmMYBML1Mixta出自于相同的祖先基因复制物,均能指导锥形细胞和毛状体在植物不同组织部位的形成,其时空表达的差异性决定了两个基因功能上的差别。本文中对花瓣锥形表皮细胞的形成及对授粉昆虫吸引作用机制的研究进展进行了综述。

Abstract: The petal conical epidermal cells of angiosperm which directly have effect on colour,smell,temperature,wettability and optical function of petal surface,optimize the specific interactions between petals and pollinators. The petal conical epidermal cells are determined by the Mixta gene. The Mixta which originated from the petal of Antirrhinum encodes a MYB transcription factor. AmMYBML1 and Mixta stem from the same ancestor gene replication. They can both guide the differentiation of conical epidermal cells and trichomes on different tissue of plants. The differences of both gene expressions decide on their different functions. This review elaborates the research progress on the mechanism of petal conical epidermal cells formation and attraction to pollinating insects.

Key words: petal, conical epidermal cell, biological property, trichome, Mixta gene, expression regulation
