Stomata are epidermal structures that modulate gas exchange between a plant and its environment. During development, stomata are specified and positioned nonrandomly by the integration of asymmetric cell divisions and intercellular signaling. The Arabidopsis mitogen-activated protein kinase kinase kinase gene, YODA, acts as part of a molecular switch controlling cell identities in the epidermis. Null mutations in YODA lead to excess stomata, whereas constitutive activation of YODA eliminated… Expand
Stomatal development and movement
TLDR
This mini-review summarizes the roles of MAPK signaling in stomatal development and movement and discusses how MAPK specificity is maintained inStomatalDevelopment and movement is discussed. Expand
Stomatal Development in Arabidopsis
TLDR
Linking the networks that control stomatal development promises to bring advances to the understanding of signal transduction, cell polarity, and cell-fate specification in plants. Expand
Arabidopsis Stomatal Initiation Is Controlled by MAPK-Mediated Regulation of the bHLH SPEECHLESS
TLDR
It is found that a unique domain in a basic helix-loop-helix (bHLH) stomatal initiating factor, SPEECHLESS, renders it a MAPK phosphorylation target in vitro and modulates its function in vivo. Expand
Signaling to stomatal initiation and cell division
TLDR
A mini review focuses on the signaling involved in stomatal initiation and in divisions in the cell lineage in Arabidopsis. Expand
Stomatal Patterning and Differentiation by Synergistic Interactions of Receptor Kinases
TLDR
This work reports that three ERECTA (ER)–family leucine-rich repeat–receptor-like kinases (LRR-RLKs) together control stomatal patterning, with specific family members regulating the specification ofStomatal stem cell fate and the differentiation of guard cells. Expand
The MAPK substrate MASS proteins regulate stomatal development in Arabidopsis
TLDR
Three MAPK SUBSTRATES in the Stomatal Lineage (MASS) proteins are functionally characterizing that they are plasma membrane-associated, positive regulators of stomatal production, providing a functional divergence of the YDA-MPK3/6 cascade in the regulation of plant developmental processes. Expand
Molecular control of stomatal development
TLDR
This work reviews the current understanding of the biochemical interactions between the epidermal patterning factor ligands and the ERECTA family of leucine-rich repeat receptor kinases and discusses how this leads to activation of a kinase cascade, regulation of the bHLH transcription factor SPEECHLESS and its relatives, and ultimately alters stomatal production. Expand
The secretory peptide gene EPF1 enforces the stomatal one-cell-spacing rule.
TLDR
A gene of Arabidopsis thaliana is reported that encodes a small secretory peptide expressed in stomatal cells and precursors and that controlsStomatal patterning through regulation of asymmetric cell division. Expand
Hormonal and environmental signals guiding stomatal development
TLDR
This review of recent findings summarizes recent findings that reveal the mechanism of these three groups of signals in controlling stomatal formation, and discusses how these signals are integrated into the coreStomatal development pathway. Expand
The missing link? Arabidopsis SPCH is a MAPK specificity factor that controls entry into the stomatal lineage
TLDR
Findings suggest that SPCH activity may be directly affected by environmental conditions to enable the plant to modify stomatal development in response to suboptimal climates. Expand

Control of Stomatal Distribution on the Arabidopsis Leaf Surface
TLDR
Arabidopsisstomata regulate gas exchange and are distributed across the leaf epidermis with characteristic spacing, and TMM appears to function in a position-dependent signaling pathway that controls the plane of patterning divisions as well as the balance between stem cell renewal and differentiation in stomatal and epidermal development. Expand
A subtilisin-like serine protease involved in the regulation of stomatal density and distribution in Arabidopsis thaliana.
TLDR
It is proposed that SDD1 acts as a processing protease involved in the mediation of a signal that controls the development of cell lineages that lead to guard cell formation in Arabidopsis thaliana. Expand
Stomatal development: cross talk puts mouths in place.
TLDR
Emerging data indicate that cell-cell signaling conveys spatial information about cell identity and location that might pattern stomata by orienting the plane of asymmetric division and might control stomatal number by regulating division frequency. Expand

TLDR
The tobacco SIPK gene (orthologous to Arabidopsis MPK6) appears to positively regulate programmed cell death and the tobacco MPK4 gene appears to negatively regulate salicylic acid-mediated defense responses and positively regulate jasmonic acid-induced responses. Expand
A MAPKK Kinase Gene Regulates Extra-Embryonic Cell Fate in Arabidopsis
TLDR
The Arabidopsis zygote divides asymmetrically into an embryonic apical cell and a basal cell with mostly extra-embryonic fate, and a MAPKK kinase gene, named YODA, that promotes extra- embryonic cell fates in the basal lineage is identified. Expand
Ultrastructure of stomatal development in Arabidopsis (Brassicaceae) leaves.
TLDR
Analysis of cell wall patterns indicates that meristemoids can divide asymmetrically a variable number of times, and this identification of stages in stomatal development in wild-type Arabidopsis provides a foundation for the analysis of relevant genes and of mutants defective inStomatal patterning, cell specification, and differentiation. Expand
The too many mouths and four lips mutations affect stomatal production in Arabidopsis.
TLDR
This work screened cotyledons from ethyl methanesulfonate-mutagenized seeds of Arabidopsis by light microscopy to identify mutants with altered stomatal morphology and found the double mutant exhibits aspects of both parental phenotypes. Expand
Plant development: Signals from mature to new leaves
TLDR
It is shown that mature leaves of Arabidopsis thaliana detect and transmit this external information to new leaves of the same plant, producing an appropriate adjustment of stomatal development. Expand
Oriented Asymmetric Divisions That Generate the Stomatal Spacing Pattern in Arabidopsis Are Disrupted by the too many mouths Mutation
TLDR
It is shown that wild-type patterning largely results when divisions next to a preexisting stoma or precursor are oriented so that the new meristemoid is placed away, and that TMM is necessary for two position-dependent events in leaves: the orientation of asymmetric divisions that pattern stomata, and the control of which cells will enter the stomatal pathway.

Suppression of auxin signal transduction by a MAPK cascade in higher plants
TLDR
It is shown that a specific plant MAPKKK, NPK1, activates a MAPK cascade that leads to the suppression of early auxin response gene transcription, suggesting that auxin sensitivity may be balanced by antagonistic signalling pathways that use a distinctMAPK cascade in higher plants. Expand
