Genome-wide Identification and Expression Analysis of the Expansin Gene Family in Potato
摘要
Abstract
As an important component of plant cell wall,expansins have effects on loosening and increasing the flexibility of cell wall,and are thought to have function in many process of plant growth. To study potential function of expansin gene family in potato,we investigated expansin gene family with the whole genome database to analyse its structure,phylogenetic relationship and expression profiles. Potato genome contained 33 expansin genes which belonged to 4 subfamilies (EXPA (21),EXPB (5),EXLA (1) and EXLB (6)) located on 11 different chromo-somes. Expansin proteins ranged from 194 aa to 488 aa in size and had conserved domains. All 33 Expansin pro-teins were predicted to localize in extracellular. Gene structure analysis revealed that seventy percent(23/33) ex-pansin genes had 2-3 introns. Transcriptome analysis showed that the potato expansin genes expressed highly in root,stem,stolon,mature fruit and tuber.关键词
