Patterning of Arabidopsis epidermal cells: epigenetic factors regulate the complex epidermal cell fate pathway
摘要：
Cell fate determination in the Arabidopsis epidermis has been extensively studied for over a decade. Epidermal cells become either trichoblasts (hair-forming cells) or atrichoblasts (non-hair-forming cells). In Arabidopsis, two types of trichoblasts are formed in defined patterns: trichomes and root hairs. Both cell types are specified through the action of a common set of transcriptional regulators that define cell pattern. Recent studies also characterize epigenetic factors in the determination of cell fate in the root, suggesting a default pattern for epidermal cell fate that can be overridden by environmental stimuli. These results reveal how plant cell developmental plasticity is controlled at the molecular level.
