TL;DR: It is shown here that RHD2 is an NADPH oxidase, a protein that transfers electrons from NADPH to an electron acceptor leading to the formation of reactive oxygen species (ROS) and that ROS accumulate in growing wild-type (WT) root hairs but their levels are markedly decreased in rhd2 mutants.

TL;DR: The anatomy of the developing root of Arabidopsis is described using conventional histological techniques, scanning and transmission electron microscopy and a model of meristem activity is proposed, which underpins future work on the developmental genetics of root morphogenesis.

TL;DR: A genetic analysis of root development in Arabidopsis thaliana has identified mutants that have abnormal morphogenesis, and genetic combinations of the four mutants have provided insight into the regulation of growth and cell shape duringArabidopsis root development.

TL;DR: Ectopic hairs are present in the ctr1 root epidermis suggesting that a Raf protein kinase may play a role in pattern formation/differentiation in theroot epider Mis and that ethylene may be a diffusible signal involved in specifying pattern in the root epidersmis.

TL;DR: The panel of anti-AGP monoclonal antibodies now available indicates groups of cells within the root meristem that may reflect an early pre-pattern of the tissues of the mature root structure and suggests extensive modulation of cell surface AGPs during cell development and the positioning of cellswithin the apex.
