Abstract: | Background Cotton (Gossypium spp.) is produced in over 30 countries and represents the most important natural fiber in the world. One of the primary factors
affecting both the quantity and quality of cotton production is water. A major facilitator of water movement through cell
membranes of cotton and other plants are the aquaporin proteins. Aquaporin proteins are present as diverse forms in plants,
where they function as transport systems for water and other small molecules. The plant aquaporins belong to the large major
intrinsic protein (MIP) family. In higher plants, they consist of five subfamilies including plasma membrane intrinsic proteins
(PIP), tonoplast intrinsic proteins (TIP), NOD26-like intrinsic proteins (NIP), small basic intrinsic proteins (SIP), and
the recently discovered X intrinsic proteins (XIP). Although a great deal is known about aquaporins in plants, very little
is known in cotton. |
