Arabidopsis trichomes are an excellent model system to study all aspects of cell differentiation including cell fate determination, cell cycle regulation, cell polarity and cell expansion. Genetic analysis had initially identified mutants affecting trichome development at different developmental stages. During recent years, molecular analysis of the corresponding genes has revealed a first glimpse of the underlying molecular mechanisms. This paper summarizes some of the recent insights…

Characterization of New Players in Planar Polarity Establishment in Arabidopsis
Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide m…
An overview of the gene regulatory network controlling trichome development in the model plant, Arabidopsis
TLDR
It has been demonstrated that the activities of the key regulatory proteins involved in trichome development are controlled by the 26S/ubiquitin proteasome system (UPS), highlighting the complexity of the regulatory network controlling this developmental process.
A Systems Approach Reveals Regulatory Circuitry for Arabidopsis Trichome Initiation by the GL3 and GL1 Selectors

Epidermal patterning in Arabidopsis: models make a difference.
TLDR
The leaf and root epidermis in Arabidopsis provide ideal systems in which to explore the mechanisms that underlie the patterned assignment of cell fates during development, and a number of recent studies using mathematical models have begun to study this network.

TLDR
The current state of understanding of genes affecting trichome development in Arabidopsis is examined, which indicates the process is amenable to genetic analysis because many mutations that affecttrichome differentiation do not alter other aspects of plant development.
Cell morphogenesis of trichomes in Arabidopsis: differential control of primary and secondary branching by branch initiation regulators and cell growth.
TLDR
It is suggested that primary branching is genetically distinct from subsequent branching events and that the latter, secondary events are initiated in response to positive and negative regulators of branching as well as subject to control by cell growth.

The control of trichome spacing and number in Arabidopsis.
TLDR
Clonal analysis of epidermal cell lineages ruled out a role for cell lineage in generating the observed minimum-distance spacing pattern, and the identification of a new locus, Reduced Trichome Number (RTN), which affects the initiation of trichomes.
SIAMESE, a gene controlling the endoreduplication cell cycle in Arabidopsis thaliana trichomes.
TLDR
A new genetic locus, SIAMESE (SIM), is described, required for coordinating cell division and cell differentiation during the development of Arabidopsis trichomes (epidermal hairs), and may function as a repressor of mitosis in the endoreduplication cell cycle.
Tissue layer and organ specificity of trichome formation are regulated by GLABRA1 and TRIPTYCHON in Arabidopsis.
Ectopic D-type cyclin expression induces not only DNA replication but also cell division in Arabidopsis trichomes
TLDR
It is shown that the expression of the D-type cyclin CYCD3;1 in endoreduplicating Arabidopsis trichome cells not only induced DNA replication but also cell divisions.
