The control of cell fate was investigated in the root epidermis of Arabidopsis thaliana . Two
distinct types of differentiated epidermal cells are normally present: root-hair-bearing Cells …

A genetic analysis of root development in Arabidopsis thaliana has identified mutants that
have abnormal morphogenesis. Four of these root morphogenesis mutants show dramatic …

The role of the Arabidopsis homeobox gene, GLABRA 2 (GL2), in the development of the
root epidermis has been investigated. The wild-type epidermis is composed of two cell types, …

Root-hair initiation in Arabidopsis thaliana provides a model for studying cell polarity and its
role in plant morphogenesis. Root hairs normally emerge at the apical end of root epidermal …

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 …

The Arabidopsis root produces a position-dependent pattern of hair-bearing and hairless
cell types during epidermis development. Five loci (TRANSPARENT TESTA GLABRA [TTG], …

The roots of terrestriaf plants are involved in the acquisition of water and nutrients, anchorage
of the plant, synthesis of plant hormones, and storage functions. The development of a root …

Multicellular organisms possess a diverse array of cell types, which vary in size, shape,
composition, and function. Therefore, a fundamental feature of development in multicellular …

In plants, morphogenesis is largely determined by the orientation and extent of cell
enlargement. To define the molecular mechanisms regulating plant cell enlargement, we have …

The role of extracellular Ca 2+ in root-hair tip growth has been investigated in Arabidopsis
thaliana (L.) Heynh. Root-hair length was found to be dependent on the concentration of Ca 2…
