... heterogeneous in the leaf blade than in the midrib and petiole, correlating with higher local differences in growth rates between neighboring cells in the blade. This local growth variability coincides with developing stomata. Stomatal lineages follow a specific, time-dependent growth program that is different...

... duplicated SCR genes function redundantly in rice. Contrary to previous reports, we show that these genes are necessary for stomatal development, with stomata virtually absent from leaves that are initiated after germination of mutants. The stomatal regulator OsMUTE is downregulated in Osscr1;Osscr2 mutants...

... attributed. Summary: Discrete roles for cell polarity and the polarity protein BASL before and after asymmetric divisions are revealed through quantitative imaging and lineage tracking of plants expressing BASL at restricted points in the cell cycle. Stomata Asymmetric cell division Cell...

...Scott M. Zeng; Emily K. W. Lo; Bryna J. Hazelton; Miguel F. Morales; Keiko U. Torii ABSTRACT Stomata are epidermal valves that facilitate gas exchange between plants and their environment. Stomatal patterning is regulated by the EPIDERMAL PATTERING FACTOR (EPF) family of secreted peptides: EPF1...

... phases enables plants to alter leaf size and stomatal density in response to environmental conditions; however, transitions between phases must be complete and unidirectional to produce functional and correctly patterned stomata. Among direct transcriptional targets of the stomatal initiating factor...

... diversity in multicellular organisms. Several conventional genetics studies have attempted to elucidate the mechanisms underlying cell polarization in plants, but it remains largely unknown. In plants, stomata, which are valves for gas exchange, are generated through several rounds of asymmetric divisions...

...Robert S. Caine; Caspar C. Chater; Yasuko Kamisugi; Andrew C. Cuming; David J. Beerling; Julie E. Gray; Andrew J. Fleming The patterning of stomata plays a vital role in plant development and has emerged as a paradigm for the role of peptide signals in the spatial control of cellular...

...Soon-Ki Han; Keiko U. Torii Stomata are dispersed pores found in the epidermis of land plants that facilitate gas exchange for photosynthesis while minimizing water loss. Stomata are formed from progenitor cells, which execute a series of differentiation events and stereotypical cell divisions...

..., which acts as a tissue-specific regulator of epidermal pattern in Arabidopsis thaliana. Arabidopsis plants produce stomata, the cellular valves required for gas exchange, in virtually all aerial organs, but stomatal density and distribution differ among organs and along organ axes. Such regional...

...Tie Liu; Kyoko Ohashi-Ito; Dominique C. Bergmann Stomata are adjustable pores in the plant epidermis that regulate gas exchange between the plant and atmosphere; they are present on the aerial portions of most higher plants. Genetic pathways controlling stomatal development and distribution have...

... locus pattern formation stomata A common phenomenon occurring during the development of many organisms is the differentiation of a specialized cell type from a field of otherwise equivalent cells. Examples include the formation of bristles in the insect epidermis ( Artavanis-Tsakonas et al...
