摘要: PIN蛋白是生长素输出蛋白,具有多个跨膜结构域,能够介导生长素在整个植物体内的流动。番茄作为一种具有重要经济价值的果蔬,对其生长发育调控的研究具有重要的意义。研究表明,PIN蛋白对植物果实的生长发育起着重要的调控作用。本研究通过生物信息学的方法对番茄PIN基因组中10 个SlPINs的核酸和氨基酸序列进行分析,构建番茄SlPINs的进化树,并分析番茄SlPINs在不同组织和果实生长发育过程中的表达量变化,为进一步研究SlPINs的生物学功能提供理论依据。

Abstract: PIN-FORMED (PIN) proteins work as auxin efflux proteins with multiple transmembrane domains and mediate auxin flow throughout the plant. As tomato is an important cash crop, studies aimed to regulate its growth and development are of great significance. Studies have shown that PIN proteins play an important role in regulating the growth and development of fruits. In this study, we predicted the characteristics of ten tomato PIN members by using on-line software, constructed a phylogenetic tree for SlPINs, and analyzed expression changes of SlPINs in different tissues and during fruit growth and development. This study will provide a basis for future study on the biological functions of SlPINs.

Key words: tomato fruit, PIN gene, bioinformatic analysis, expression pattern
