GLABROUS1 overexpression and TRIPTYCHON alter the cell cycle and trichome cell fate in Arabidopsis. Szymanski DB, Marks MD. Plant Cell. 1998 Dec;10(12):2047-62. ...... control the distribution of trichomes on the Arabidopsis leaf. The GLABROUS1 (GL1) gene has a dual role in that it is required for trichome initiation, but GL1 overexpression reduces trichome number. We have found that a mutation in the TRIPTYCHON (TRY) gene partially suppresses the GL1 overexpression phenotype but not in a way that indicates that TRY directly controls an epidermal inhibition pathway. Surprisingly, cauliflower mosaic virus 35S::GL1 try plants contain a subclass of ...... |

Tissue layer and organ specificity of trichome formation are regulated by GLABRA1 and TRIPTYCHON in Arabidopsis. Schnittger A, Jurgens G, Hulskamp M. Development. 1998 Jun;125(12):2283-9. ...... a distinct set of cell types. To investigate the role of tissue-layer-specific cues in generating plant cellular diversity we studied the spatial regulation of an epidermal cell type, trichomes (hairs), by the two genes, GLABRA1 (GL1) and TRIPTYCHON (TRY). Ubiquitous expression of the positive regulator GL1 in the absence of the negative regulator TRY leads to ectopic trichome formation not only on additional organs but also in subepidermal tissue layers. Trichomes in inner tissue ...... |

A competitive complex formation mechanism underlies trichome patterning on Arabidopsis leaves Digiuni S, Schellmann S, Geier F, Greese B, Pesch M, Wester K, Dartan B, Mach V, Srinivas BP, Timmer J, Fleck C, Hulskamp M. Mol Syst Biol. 2008;4:217. Epub 2008 Sep 2 ...... patterning system, we developed a new theoretical model that allows the direct testing of the effect of experimental interventions and in the prediction of patterning phenotypes. We show experimentally that the trichome inhibitor TRIPTYCHON is transcriptionally activated by the known positive regulators GLABRA1 and GLABRA3. Further, we demonstrate by particle bombardment of protein fusions with GFP that TRIPTYCHON and CAPRICE but not GLABRA1 and GLABRA3 can move between ...... |

Comprehensive analysis of single-repeat R3 MYB proteins in epidermal cell patterning and their transcriptional regulation in Arabidopsis. Wang S, Hubbard L, Chang Y, Guo J, Schiefelbein J, Chen JG. BMC Plant Biol. 2008 Jul 21;8:81 ...... are critical components of the lateral inhibition machinery that mediates epidermal cell patterning in plants. Sequence analysis of the Arabidopsis genome using the BLAST program reveals that there are a total of six genes, including TRIPTYCHON (TRY), CAPRICE (CPC), TRICHOMELESS1 (TCL1), and ENHANCER of TRY and CPC 1, 2, and 3 (ETC1, ETC2 and ETC3) encoding single-repeat R3 MYB transcription factors that are approximately 50% identical to one another at the amino acid level. ...... |

Constitutive Expressor Of Pathogenesis-related Genes5 affects cell wall biogenesis and trichome development. Brininstool G, Kasili R, Simmons LA, Kirik V, Hulskamp M, Larkin JC. BMC Plant Biol. 2008 May 16;8:58. ...... less paracrystalline cellulose and had an altered wall carbohydrate composition. We also found that the effects of cpr5 on trichome size and endoreplication of trichome nuclear DNA were epistatic to the effects of mutations in triptychon (try) or overexpression of GLABRA3, indicating that these trichome developmental regulators are dependant on CPR5 function for their effects on trichome expansion and endoreplication. CONCLUSION: Our results suggest that CPR5 is unlikely to be ...... |

Participation of the Arabidopsis bHLH factor GL3 in trichome initiation regulatory events. Morohashi K, Zhao M, Yang M, Read B, Lloyd A, Lamb R, Grotewold E. Plant Physiol. 2007 Nov;145(3):736-46. ...... (GL3) basic helix-loop-helix transcription factor. Within this developmental window, GL3 binds to the promoters of at least three genes previously implicated in the development and patterning of trichomes (GL2, CAPRICE, and ENHANCER OF TRIPTYCHON AND CAPRICE1) and activates their transcription. The in vivo binding of GL3 to the promoters of these genes requires the presence of the R2R3-MYB factor GL1, supporting a model in which a GL3-GL1 complex is part of the trichome initiation ...... |

Analysis of gene expression in cotton fiber initials. Taliercio EW, Boykin D. BMC Plant Biol. 2007 May 16;7:22. ...... Staining ovules with a fluorescent dye confirmed an increase in Endoplasmic Reticulum (ER) occurred in fiber initials on the day of anthesis, persisted through 3 dpa and was absent in a fiberless mutant. Two genes similar to the CAPRICE/TRIPTYCHON (CPC) gene that inhibits differentiation of leaf trichomes in Arabidopsis were also characterized. Genes associated with novel regulation of brassinosterols, GTP mediated signal transduction and cell cycle control and components of a Ca+2 ...... |

ENHANCER of TRY and CPC 2 (ETC2) reveals redundancy in the region-specific control of trichome development of Arabidopsis. Kirik V, Simon M, Wester K, Schiefelbein J, Hulskamp M. Plant Mol Biol. 2004 May;55(3):389-98. ...... development. Their function is difficult to assess because most of them belong to multigene families and appear to act in a redundant fashion. In this study we identified an enhancer of the two root hair and trichome patterning mutants triptychon (try) and caprice (cpc), enhancer of try and cpc2 (etc2). The ETC2 gene shows high sequence similarity to the single-repeat MYB genes CPC and TRY. Overexpression results in the suppression of trichomes and overproduction of root hairs ...... |

The ENHANCER OF TRY AND CPC1 gene acts redundantly with TRIPTYCHON and CAPRICE in trichome and root hair cell patterning in Arabidopsis. Kirik V, Simon M, Huelskamp M, Schiefelbein J. Dev Biol. 2004 Apr 15;268(2):506-13. ...... The development of trichomes and root hairs in Arabidopsis provide useful models for the study of cell fate determination in plants. A common network of putative transcriptional regulators, including the small MYB proteins TRIPTYCHON (TRY) and CAPRICE (CPC), is known to influence the patterning of both cell types. Here, we used an activation tagging strategy to identify a new regulator, ENHANCER OF TRY AND CPC 1 (ETC1). The ETC1 sequence is similar to TRY and CPC, ...... |

TRIPTYCHON and CAPRICE mediate lateral inhibition during trichome and root hair patterning in Arabidopsis. Schellmann S, Schnittger A, Kirik V, Wada T, Okada K, Beermann A, Thumfahrt J, Jurgens G, Hulskamp M. EMBO J. 2002 Oct 1;21(19):5036-46. ...... Trichome patterning in Arabidopsis is a model for the generation of a spacing pattern from initially equivalent cells. We show that the TRIPTYCHON gene that functions in lateral inhibition encodes a single-repeat MYB-related transcription factor that lacks a recognizable activation domain. It has high sequence similarity to the root hair patterning gene CAPRICE. Both genes are ...... |

Ectopic expression of the Arabidopsis AtMYB23 gene induces differentiation of trichome cells. Kirik V, Schnittger A, Radchuk V, Adler K, Hulskamp M, Baumlein H. Dev Biol. 2001 Jul 15;235(2):366-77. ...... AtMYB23 gene under the control of the viral CaMV 35S promoter causes the development of ectopic trichomes. The formation of ectopic trichomes depends on TRANSPARENT TESTA GLABRA1 but not on GLABRA1. The absence of the negative regulator TRIPTYCHON leads to branching of the ectopic trichomes on cotyledons and the formation of ectopic trichomes in the leaf subepidermal cell layer. The CaMV 35S promoter-controlled expression of AtMYB23 can partially rescue the glabra1 mutant ...... |

SIAMESE, a gene controlling the endoreduplication cell cycle in Arabidopsis thaliana trichomes. Walker JD, Oppenheimer DG, Concienne J, Larkin JC. Development. 2000 Sep;127(18):3931-40. ...... relative to WT trichome nuclei. Endoreduplication is also reduced in dark-grown sim hypocotyls relative to WT, but not in light-grown hypocotyls. Double mutants of sim with either of two other mutants affecting endoreduplication, triptychon (try) and glabra3 (gl3) are consistent with a function for SIM in endoreduplication. SIM may function as a repressor of mitosis in the endoreduplication cell cycle. Additionally, the relatively normal morphology of multicellular sim ...... |

Generation of a spacing pattern: the role of triptychon in trichome patterning in Arabidopsis. Schnittger A, Folkers U, Schwab B, Jurgens G, Hulskamp M. Plant Cell. 1999 Jun;11(6):1105-16. ...... Trichomes in Arabidopsis are single-celled hairs that exhibit a regular spacing pattern. Here, the role of TRIPTYCHON (TRY) in the generation of this spacing pattern is studied. By using genetic mosaics, we demonstrate that the formation of trichome clusters in try mutants is not correlated with cell lineage, indicating that TRY is required to single out ...... |

Trichome cell growth in Arabidopsis thaliana can be derepressed by mutations in at least five genes. Perazza D, Herzog M, Hulskamp M, Brown S, Dorne AM, Bonneville JM. Genetics. 1999 May;152(1):461-76. ...... Leaf trichomes in Arabidopsis are unicellular epidermal hairs with a branched morphology. They undergo successive endoreduplication rounds early during cell morphogenesis. Mutations affecting trichome nuclear DNA content, such as triptychon or glabra3, alter trichome branching. We isolated new mutants with supernumerary trichome branches, which fall into three unlinked complementation groups: KAKTUS and the novel loci, POLYCHOME and RASTAFARI. They map to chromosomes IV, II, ...... |
