Hormone helps plants build leaves' ventilation system

As the world heats up, plants face a dilemma – the same tiny holes they have to open to exchange gases also let out water. They can close the holes, called stomata, to stay hydrated in hotter, drier conditions but, in doing so, may miss out on critical carbon dioxide. Researchers in Professor Dominique Bergmann's  lab at Stanford has shown how one hormone pathway in plants regulates the way leaves build their epidermal layer with the right number of breathing pores, giving plants a strategy to optimize their productivity while taking into account changes in the environment. The study was published September 6 in Developmental Cell.
