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 ...... 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 cells. Finally, theoretical considerations suggest promoter swapping and basal overexpression experiments by means of which we are able to discriminate three biologically meaningful variants of ...... |

Quantitative analysis of heterogeneous spatial distribution of Arabidopsis leaf trichomes using micro X-ray computed tomography. Kaminuma E, Yoshizumi T, Wada T, Matsui M, Toyoda T. Plant J. 2008 Nov;56(3):470-82. Epub 2008 Jul 4.Click here to read ...... proportion of large trichomes. The data reflect spatial heterogeneity in the radial direction, in that a greater number of trichomes were observed on the leaf blade margins relative to the non-margins, a distribution effect caused by the CAPRICE (CPC) and GLABRA3 (GL3) genes, which have previously been shown to affect trichome density. We further determined that the proportion of large trichomes on the blade mid-rib increases from the proximal end to the distal leaf tip in both ...... |

...... plants and GL3 mutants. Our results indicate that the CPC [corrected] gene affects trichome distribution, rather than trichome growth, causing trichome initiation at the proximal base rather than the distal tip. On the other hand, CPC does affect trichome growth and developmental progression. Hence, quantitative phenotyping based on microCT enables precise phenotypic description for elucidation of gene control in morphological mutants. ...... |

Arabidopsis CAPRICE-LIKE MYB 3 (CPL3) controls endoreduplication and flowering development in addition to trichome and root hair formation. Tominaga R, Iwata M, Sano R, Inoue K, Okada K, Wada T. Development. 2008 Apr;135(7):1335-45. ...... an additional homolog, CPC-LIKE MYB 3 (CPL3), which has high sequence similarity to CPC, TRY, ETC1 and ETC2. Overexpression of CPL3 results in the suppression of trichomes and overproduction of root hairs, as has been observed for CPC, TRY, ETC1 and ETC2. Morphological studies with double, triple and quadruple homolog mutants indicate that the CPL3 gene cooperatively regulates epidermal cell differentiation with other CPC homologs. Promoter-GUS analyses indicate that ...... |

TRICHOMELESS1 regulates trichome patterning by suppressing GLABRA1 in Arabidopsis. Wang S, Kwak SH, Zeng Q, Ellis BE, Chen XY, Schiefelbein J, Chen JG. Development. 2007 Nov;134(21):3873-82. ...... elevated expression of TCL1 has a glabrous (trichomeless) phenotype, whereas a loss-of-function mutation in TCL1 uniquely confers ectopic trichome formation on inflorescence stem and pedicels. Genetic analyses demonstrate that TCL1 and CAPRICE work synergistically to regulate trichome patterning on these organs. Interestingly, overexpression of TCL1 specifically suppresses the expression of GLABRA1 (GL1), a crucial component in the trichome initiation complex, whereas ...... |

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. ...... 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 similarly as observed ...... |

...... and CPC suggesting that ETC2 has similar biochemical properties. The etc2 single mutant shows an increase in trichome number on leaves and petioles. Double and triple mutant analysis indicates that the ETC2 gene acts redundant with TRY and CPC in trichome patterning. ...... |

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. ...... 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, and ETC1 overexpression ...... |

...... and excessive root hair production. The etc1 single mutant has no significant phenotype, but it enhances the effect of cpc and try on trichome and root hair development, which shows that ETC1 function is partially redundant with TRY and CPC. In addition, the etc1 try cpc triple mutant has novel phenotypes, revealing previously unrecognized roles for these regulators in epidermis development. An ETC1 promoter-reporter gene fusion is expressed in the developing trichome and ...... |

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. ...... 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 expressed in trichomes and act together during lateral inhibition. We further show that TRIPTYCHON and CAPRICE act redundantly in the position-dependent cell fate determination in the root epidermis. Thus, the same lateral ...... |
