Abstract excerpt
In plants, water vapour is released into the atmosphere through stomata in a process called transpiration. Abscisic acid (ABA) is a key phytohormone that facilitates stomatal closure through its action on guard cells. Recently, ATP-binding cassette (ABC) transporter genes, AtABCG25 and AtABCG40, were shown to be involved in ABA transport and responses. However, the functions of many other AtABCG family genes are...
