Stomatal development.
TLDR
This review synthesizes what is known about the mechanisms and genes underlying stomatal development and contrast the functions of genes that act earlier in the pathway, including receptors, kinases, and proteases with those that act later in the cell lineage. 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
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. 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
The Arabidopsis R2R3 MYB Proteins FOUR LIPS and MYB88 Restrict Divisions Late in the Stomatal Cell Lineage
TLDR
The results suggest that two related transcription factors jointly restrict divisions late in the Arabidopsis thaliana stomatal cell lineage. Expand
Stomatal Development in Arabidopsis
TLDR
The molecular analysis of stomatal development promises advances in understanding intercellular signaling, the control of the plane and polarity of asymmetric division, the specification of cell fate, and the regulation of cell differentiation and shape. Expand
Plant gravity sensing.

  • International review of cytology
  • 1991
This review of plant gravity sensing examines sensing in organ gravitropism, sensing in single-cell gravitropism, and nongravitropic sensing. Topics related to sensing in organ gravitropism are (1)Expand
Plastids and gravitropic sensing

  • 1 September 1997
TLDR
The simplest interpretation of these data is that gravitropic sensing is plastid-based, since starchless and intermediate starch mutants show reduced grav itropic sensitivity. Expand
Ultrastructure of stomatal development in Arabidopsis (Brassicaceae) leaves.

  • 1 July 1999
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
Developmental regulation of CYCA2s contributes to tissue‐specific proliferation in Arabidopsis
TLDR
Downregulation of CYCA2s represents a critical mechanism to coordinate proliferation during plant development and is shown to require the stomatal transcription factors FOUR LIPS/MYB124 and MYB88, providing a direct link between developmental programming and cell‐cycle exit in plants. Expand
