Genetic Mechanisms Regulating Root Cap Cell Renewal in Arabidopsis thaliana L.
Abstract
Synchronization of spatially separated processes of cells’ division and loss is crucial in renewal and maintenance of organ and tissue structure; however, genetic mechanisms of its regulation are poorly understood. In plants, root cap located at the root tip is quickly renewed protecting the stem cell niche against mechanical injury and performing some other important functions. In spite of continuous supply and differentiation of daughter cells from division of initials (stem cells), the root cap size does not increase because of regular sloughing of differentiated cells at its apex. In order to strictly maintain a permanent size of the root cap, it is important to synchronize divisions of stem cells with removal of the outer cell layer. In Arabidopsis thaliana, which is a model species in plant genetics, root cap structure is plain and well-ordered, and old cells are sloughed as a whole layer; that is why this species is a convenient object for investigation of the mechanisms responsible for root cap renewal. It this review, we will consider maintenance of root cap structure and size in A. thaliana and discuss the data concerning genetic control over this process and promising research avenues in this area.
期刊介绍:
Russian Journal of Plant Physiology is a leading journal in phytophysiology. It embraces the full spectrum of plant physiology and brings together the related aspects of biophysics, biochemistry, cytology, anatomy, genetics, etc. The journal publishes experimental and theoretical articles, reviews, short communications, and descriptions of new methods. Some issues cover special problems of plant physiology, thus presenting collections of articles and providing information in rapidly growing fields. The editorial board is highly interested in publishing research from all countries and accepts manuscripts in English.
