Technical Abstract: Aquaporins are intrinsic membrane proteins present across kingdoms. In plants, aquaporins play roles in intercellular and intracellular water movement in response to osmotic and hydraulic potentials resulting from changing environmental conditions. In higher plants, aquaporins consist of five subfamilies that are plasma membrane intrinsic proteins (PIP), tonoplast intrinsic proteins (TIP), NOD26-like intrinsic proteins (NIP), small basic intrinsic proteins (SIP), and previously unrecognized X-intrinsic proteins (XIP). In addition to the role as water channels, aquaporins are functionally versatile and have diverse substrate specificity to specific small, non-polar solutes. We are analyzing aquaporin gene sequences from different Gossypium species to determine the sub-genomic makeup of the cotton aquaporin gene family. The recent release of the genome sequence of a D-genome diploid ancestor (G. raimondii) will guide the analysis of the complex and large aquaporin gene family in the cultivated, tetraploid cotton genome (AD-genome).
