Role of a positive regulator of root hair development, CAPRICE, in Arabidopsis root epidermal cell differentiation.
In Arabidopsis, root hairs are formed only from a set of epidermal cells named trichoblasts or hair-forming cells. Previous studies showed CAPRICE (CPC) promotes differentiation of hair-forming cells by controlling a negative regulator, GLABRA2 (GL2), which is preferentially expressed in hairless cells. Here, we show that CPC is also predominantly expressed in the hairless cells, but not in the...
متن کاملEnvironmentally induced plasticity of root hair development in Arabidopsis.
Postembryonic development of plants is dependent on both intrinsic genetic programs and environmental factors. The plasticity of root hair patterning in response to environmental signals was investigated in the Columbia-0 wild type and 19 Arabidopsis mutants carrying lesions in various parts of the root hair developmental pathway by withholding phosphate or iron (Fe) from the nutrient medium. I...
متن کاملGenetic Control of Root Hair Development in Arabidopsis thaliana.
Visual examination of roots from 12,000 mutagenized Arabidopsis seedlings has led to the identification of more than 40 mutants impaired in root hair morphogenesis. Mutants from four phenotypic classes have been characterized in detail, and genetic tests show that these result from single nuclear recessive mutations in four different genes designated RHD1, RHD2, RHD3, and RHD4. The phenotypic a...
متن کاملThe Arabidopsis root hair mutants der2-der9 are affected at different stages of root hair development.
Root hairs are an excellent model system to study cell developmental processes as they are easily accessible, single-celled, long tubular extensions of root epidermal cells. In a genetic approach to identify loci important for root hair development, we have isolated eight der (deformed root hairs) mutants from an ethylmethanesulfonate (EMS)-mutagenized Arabidopsis population. The der lines repr...
متن کاملRoot Hair Growth in Arabidopsis thaliana
We study the factors that affect the root hair growth in the Arabidopsis thaliana plant. From experimental data, we measure how the average velocities of growth and tip shapes of the root hairs are affected by pressure and nutrients. Then using a biomechanical model, we can compute the physical parameters of the root hair and aim to correlate our model with experiments by using image processing...
