摘要
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。
PIN gene family is one of the important efflux carrier regulating auxin translocation. Auxin transport mediated by Arabidopsis thaliana auxin efflux carrier PIN2 and auxin unsymmetrical distribution played an important role to the gravity response in the root（Pan et al., 2010）. Gravity of plant roots determineed the trend of root growth space. It had an important influence on plant nutrient absorption. This research chosed gene PIN2 from Arabidopsis thaliana which we already knew its functions as reference sequence and focused on the bioinformatics analysis, protein composition and physicochemical properties, phylogenetic analysis, protein structure prediction and transmembrane domains analysis. These results would be helpful for studying biology function of PIN2 of tomato.
