The diversity of stomatal development regulation in Callitriche is related to the intrageneric diversity in lifestyles.

ABSTRACT: Stomata, the gas exchange structures of plants, are formed by the division and differentiation of stem cells, or meristemoids. Although diverse patterns of meristemoid behavior have been observed among different lineages of land plants, the ecological significance and diversification processes of these different patterns are not well understood. Here we describe an intrageneric diversity in the patterns of meristemoid division within the ecologically diverse genus Callitriche (Plantaginaceae). Meristemoids underwent a series of divisions before differentiating into stomata in the terrestrial species of Callitriche, but these divisions did not occur in amphibious species, which can grow in both air and water, in which meristemoids differentiated directly into stomata. These fi
