SCHIZORIZA controls an asymmetric cell division and restricts epidermal identity in the Arabidopsis root.
The primary root of Arabidopsis has a simple cellular organisation. The fixed radial cell pattern results from stereotypical cell divisions that occur in the meristem. Here we describe the characterisation of schizoriza (scz), a mutant with defective radial patterning. In scz mutants, the subepidermal layer (ground tissue) develops root hairs. Root hairs normally only form on epidermal cells of...
متن کاملSCHIZORIZA Encodes a Nuclear Factor Regulating Asymmetry of Stem Cell Divisions in the Arabidopsis Root
Cell divisions generating daughter cells different in size, shape, identity, and function are indispensable for many developmental processes including fate specification, tissue patterning, and self-renewal. In animals and yeast, perturbations in factors required for well-described asymmetric cell divisions generally yield cells of equal fate. Here we report on SCHIZORIZA (SCZ), a single nuclea...
متن کاملSCHIZORIZA Controls Tissue System Complexity in Plants
The formation of different tissue systems in multicellular organisms depends on the activity of groups of undifferentiated cells called stem cells. In vascular plants, the three principal tissue systems--dermal, ground, and vascular--are derived from specific groups of stem cells that are laid down during embryogenesis. We show here that SCHIZORIZA (SCZ) is necessary for the early establishment...

Background and objectives: Many Nepeta species have been commonly used in Iranian folk medicine as tranquilizer, relaxant, carminative and restorative tonic for nervous and respiratory disorders. Inflammation is a problem in many diseases and has an important role in brain function that can cause neurodegenerative disorders. Inflamed glial cells can exacerbate neurodegenerative disease...
