Role of Aquaporins in Determining Carbon and Nitrogen Status in Higher Plants
Aquaporins (AQPs) are integral membrane proteins facilitating the transport of water and some small neutral molecules across cell membranes. In past years, much effort has been made to reveal the location of AQPs as well as their function in water transport, photosynthetic processes, and stress resp...
