藜麦异戊烯基转移酶基因(CqIPT)家族的全基因组鉴定与分析

Genome-wide Identification and Analysis of Isopentenyltransferase Gene(CqIPT)Family in Quinoa(Chenopodium quinoa Willd.)

基于藜麦全基因组和转录组数据,利用生物信息学的方法对藜麦IPT(CqIPT)基因家族进行了鉴定和系统分析。结果表明,在藜麦基因组中鉴定到12个可分为4个亚组的CqIPT基因,同亚组CqIPT基因具有相似的基因结构和蛋白Motif结构;CqIPT基因家族所有成员的表达模式存在明显差异,CqIPT9仅在顶端分生组织和花序中显著表达,CqIPT5和CqIPT11在花和未成熟的种子及干种子中显著表达;非生物胁迫下的基因表达同样存在多种模式。本研究为深入研究藜麦CqIPT基因的功能提供了一定的理论基础。

The IPT gene family of quinoa is identified and systematically analyzed using bioinformatics methods based on the whole genome and transcriptome data of quinoa.The results show that 12 CqIPT genes are identified in the quinoa genome,which could be divided into 4 phylogenetic subgroups.The same phylogenetic subgroup CqIPT genes have similar gene structure and protein Motif structure.The expression patterns of CqIPT gene family members are significantly different.CqIPT9 only expresses in apical meristem and inflorescence.CqIPT5 and CqIPT11are highly expressed in flowers,immature seeds and dry seeds.There are also varied patterns of gene expression under abiotic stress.The results provide a theoretical basis for further study on the function of CqIPT gene in quinoa.
