The too many mouths and four lips mutations affect stomatal production in Arabidopsis.
Stomata regulate gas exchange through the aerial plant epidermis by controlling the width of a pore bordered by two guard cells. Little is known about the genes that regulate stomatal development. We… Expand
Stomata are cellular epidermal valves in plants central to gas exchange and biosphere productivity. The pathways controlling their formation are best understood for Arabidopsis thaliana where stomata… Expand
Oriented Asymmetric Divisions That Generate the Stomatal Spacing Pattern in Arabidopsis Are Disrupted by the too many mouths Mutation
Wild-type stomata are spaced by intervening cells, a pattern disrupted in the Arabidopsis mutant too many mouths (tmm). To determine the mechanism of wild-type spacing and how tmm results in pattern… Expand
Control of Stomatal Distribution on the Arabidopsis Leaf Surface
Stomata regulate gas exchange and are distributed across the leaf epidermis with characteristic spacing. Arabidopsisstomata are produced by asymmetric cell divisions. Mutations in the gene TOO MANY… Expand
The Arabidopsis R2R3 MYB Proteins FOUR LIPS and MYB88 Restrict Divisions Late in the Stomatal Cell Lineage
The two guard cells of a stoma are produced by a single symmetric division just before terminal differentiation. Recessive mutations in the FOUR LIPS (FLP) gene abnormally induce at least four guard… Expand
Stomatal Development in Arabidopsis
Abstract Stomata consist of two guard cells around a pore and act as turgor-operated valves for gas exchange. Arabidopsis stomata develop from one or more asymmetric divisions followed by the… Expand

Abstract. Data and theories about the identity of the mass that acts in gravitropic sensing are reviewed. Gravity sensing may have evolved several times in plants and algae in processes such as… Expand
Ultrastructure of stomatal development in Arabidopsis (Brassicaceae) leaves.
Stomatal development was studied in wild-type Arabidopsis leaves using light and electron microscopy. Development involves three successive types of stomatal precursor cells: meristemoid mother… Expand
Developmental regulation of CYCA2s contributes to tissue‐specific proliferation in Arabidopsis
In multicellular organisms, morphogenesis relies on a strict coordination in time and space of cell proliferation and differentiation. In contrast to animals, plant development displays continuous… Expand
