PIN基因家族是调控生长素运输的重要输出载体。拟南芥PIN2介导的生长素极性运输在生长素不对称分布在根的向重力性反应中起着关键性调控作用(潘建伟等,2010)。植物根系的重力性决定着根系空间生长的趋势,对植物养分的吸收有着重要的影响。本研究选择功能已知的拟南芥PIN2基因为参考序列,对番茄PIN2基因开展了蛋白组分和理化性质,系统进化分析,蛋白结构预测,跨膜结构分析等生物信息学研究,为番茄PIN2基因的生物学功能及分子机理提供理论基础。
The PIN gene family is an important export vector for the regulation of auxin transport. Arabidopsis PIN2-mediated auxin polar transport plays a key regulatory role in the gravitropic response of auxin to the auxin distribution (Pan et al., 2010). Gravitropism of plant roots determines the trend of root space growth, the absorption of plant nutrients has an important impact. In this study, we selected the known Arabidopsis PIN2 gene as a reference sequence and carried out bioinformatics studies on the protein components, physicochemical properties, phylogenetic analysis, protein structure prediction and transmembrane structural analysis of tomato PIN2 gene. Genes provide the theoretical basis for the biological function and molecular mechanism.
