Abstract: 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.

Key words: cotton, aquaporin, salt tolerance, drought resistance, molecular clustering
