Epidermal fate map of the Arabidopsis shoot meristem.
Schnittger A, Grini PE, Folkers U, Hulskamp M. Dev Biol. 1996 May 1;175(2):248-55.

...... (L2 and L3). The origin of adult structures has previously been fate mapped to the primary meristem for L2 and L3 tissues. In this work we constructed a fate map of L1 cells in the embryonic shoot meristem. Using the trichome mutation stichel as an epidermal marker, we analyzed 153 plants that included 178 sectors. Sectors on early leaves were found to be smaller and occurred more frequently than those on late leaves. Sectors on late leaves also appeared often to affect more ......

The Arabidopsis STICHEL gene is a regulator of trichome branch number and encodes a novel protein.
Ilgenfritz H, Bouyer D, Schnittger A, Mathur J, Kirik V, Schwab B, Chua NH, Jurgens G, Hulskamp M. Plant Physiol. 2003 Feb;131(2):643-55.

...... Here, we analyze the STICHEL (STI) gene, which plays an important role in the regulation of branch number of the unicellular trichomes in Arabidopsis. We have isolated the STI locus by positional cloning and confirmed the identity by sequencing seven independent sti ......

Trichome morphogenesis: a cell-cycle perspective.
Schnittger A, Hulskamp M. Philos Trans R Soc Lond B Biol Sci. 2002 Jun 29;357(1422):823-6. Review.

...... Arabidopsis leaf hairs (trichomes) are polyploid epidermal cells with a predictable branching pattern. More than 15 genes have been identified that are involved in the regulation of branching. The cloning of the ZWICHEL, ANGUSTIFOLIA and STICHEL genes points to two mechanistic aspects of branch formation: (i) a role of the microtubule cytoskeleton; and (ii) a link to the regulation of cell divisions. The latter aspect is supported by the recent identification of an Arabidopsis ......
