Researchers notice pattern on surface of leaves, uncover new clue about plant evolution

A doctoral student has identified a long-overlooked pattern in how plants evolved their equivalent of lungs -- tiny pores on the surfaces of leaves called stomata. Using specialized imaging techniques and a plant species not often found in laboratories, researchers say this discovery reveals a key difference in the evolution of plants that live on land versus those that can grow in water.
