棉花水通道蛋白序列生物信息学初步分析

摘要

Aquaporin(AQP) is a kind of inner epicyte protein which efficiently transports water molecule relevant to drought resistance and plays an important role in water regulation. To evaluate and analyze cotton AQP sequence resources preliminarily, the latest 52 AQP sequences from cotton public database were selected and analyzed by molecular clustering, multi-sequence alignment and distribution and location of AQP genes in subtype cell. The results indicated that AQPs were roughly divided into seven categories with a rich diversity, and AQP genes played an important role in the transportation through membrane and photosynthesis. Besides, 328 AQP sequences from rice, soybean , maize, Arabidopsis and the latest online 52 AQP sequences available in cotton were carried out with molecular clustering. The results showed that 48 out of the 52 AQP sequences in cotton and soybean gathered for a clustering with a closer genetic distance.%水通道蛋白(aquaporin,AQP)是高效转运水分子的膜内在蛋白,在调控植物的水分关系中有重要作用,和抗旱性能紧密相关.为初步评价分析棉花AQP序列资源,对网上最新且仅有的52条棉花AQP序列进行分子聚类,同时将其进行多序列比对及亚细胞定位,结果表明:棉花AQP大致分为7类,具有丰富的多样性,AQP基因在跨膜转运以及光合中起重要作用.另外,来自水稻、大豆、玉米、拟南芥的328条AQP序列和52条棉花AQP序进行分子聚类,结果表明:有48条棉花AQP和大豆聚为一类,遗传距离较接近.
