The Arabidopsis STICHEL gene is a regulator of trichome branch number and encodes a novel protein.
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 alleles. The STI gene encodes a protein of 1,218 amino acid residues containing a domain with sequence similarity to the ATP-bindi...
متن کاملGenetic control of trichome branch number in Arabidopsis: the roles of the FURCA loci.
We are using trichome (hair) morphogenesis as a model to study how plant cell shape is controlled. During a screen for new mutations that affect trichome branch initiation in Arabidopsis, we identified seven new mutants that show a reduction in trichome branch number from three branches to two. These mutations were named furca, after the Latin word for two-pronged fork. These seven recessive mu...
متن کاملGL3 encodes a bHLH protein that regulates trichome development in arabidopsis through interaction with GL1 and TTG1.
Arabidopsis trichome development and differentiation is a well-studied model for plant cell-fate determination and morphogenesis. Mutations in TRANSPARENT TESTA GLABRA1 (TTG1) result in several pleiotropic defects including an almost complete lack of trichomes. The complex phenotype caused by ttg1 mutations is suppressed by ectopic expression of the maize anthocyanin regulator R. Here it is dem...
متن کاملIRREGULAR TRICHOME BRANCH1 in Arabidopsis encodes a plant homolog of the actin-related protein2/3 complex activator Scar/WAVE that regulates actin and microtubule organization.
The dynamic actin cytoskeleton is important for a myriad of cellular functions, including intracellular transport, cell division, and cell shape. An important regulator of actin polymerization is the actin-related protein2/3 (Arp2/3) complex, which nucleates the polymerization of new actin filaments. In animals, Scar/WAVE family members activate Arp2/3 complex-dependent actin nucleation through...
متن کاملTRICHOMELESS1 regulates trichome patterning by suppressing GLABRA1 in Arabidopsis.
The patterning of epidermal cell types in Arabidopsis is a simple and useful model for studying the molecular basis of cell specification in plants. The distribution of different cell types in the Arabidopsis epidermis is regulated by a lateral inhibition mechanism that relies on interactions between transcription factors. However, it is unclear how temporal- or organ-specific differences in ep...
