甘蓝型油菜PHT1家族的全基因组鉴定、结构及特征
首发时间:2016-05-26
摘要:植物PHT1磷转运蛋白家族在植物磷吸收、体内磷分配及再利用等过程中发挥了重要作用。本研究从公共数据库中查找了甘蓝型油菜PHT1家族的全部成员,并利用生物信息学的方法分析了该家族成员的结构、进化及理化性质等基本特征。研究结果表明,甘蓝型油菜全基因组中至少存在48个PHT1家族成员,分布在除A1、A10和C1外的16条染色体上,mRNA长度为1152 bp ~2771 bp,氨基酸长度为281~805,其中39个成员含有10~12个跨膜结构域,少部分成员可能由于序列缺失或膜退化原因导致其跨膜结构域个数较少。进化分析表明甘蓝型油菜PHT1家族成员至少被分成4个的亚组,主要与双子叶植物同源基因聚在一类。本研究为深入探讨PHT1家族成员在油菜磷吸收转运中的作用奠定了基础。

Whole-genomic identification and characterization of PHT1 family genes in Brassica napus
Abstract:Plant PHT1 family have played vital important roles in phosphorus (P) absorption, P distribution and recycling in plants. In the present study, we identify all the members of PHT1 family in Brasscia napu from public data. In the present study, the structure, evolution and physicochemical properties of B. napus PHT1 family members are analyzed by bioinformatics tools. Our results show that there are 48 members in the whole genome of B. napus, scattering over 16 chromosomes except A1, A10 and C1. The mRNA length of all members varies from 1152 bp to 2771 bp, while the amino acid length ranges from 281 to 805. Among them, 39 members contain 10 to 12 transmembrane domains, except some with sequence deletion or membrane degradation. Phylogenetic analysis shows that PHT1 family genes can be divided into at least four groups, together with dicots. Our results provide basis for further research of the role of B. napus PHT1 family members in P uptake and transportation.
