image: Light microscopy images of the wild-type epidermis (left panel) and mutant epidermis (right panel). The wild-type epidermis features four-celled stomata consisting of two central guard cells and two lateral subsidiary cells, whereas the mutant epidermis features two-celled stomata only, which lack the lateral subsidiary cells. Two stomatal complexes are shown in both images, which are surrounded by large, rectangular pavement cells and smaller, round hair cells. This material relates to a paper that appeared in the March 17, 2017, issue of Science, published by AAAS. The paper, by M.T. Raissig at Stanford University in Stanford, Calif., and colleagues was titled, "Mobile MUTE specifies subsidiary cells to build physiologically improved grass stomata." view more
