Arabidopsis root hairs do not only grow at their tip - Nature
WEBNov 1, 2022 — Root hairs have long been considered to elongate exclusively by so-called tip growth, in which the new building material is deposited at the root hair apex. Using a set of newly developed...
Root hair - Wikipedia
WEBRoot hair, or absorbent hairs, are outgrowths of epidermal cells, specialized cells at the tip of a plant root. They are lateral extensions of a single cell and are only rarely branched. They are found in the region of maturation, of the root.

WEBApr 4, 2002 — Photograph of a root tip showing the progressive development of root hair cells. This chapter provides a summary of the development, structure, and function of root hairs in Arabidopsis. Particular emphasis is placed on recent findings on the molecular genetics of root hair development.
Root hairs: development, growth and evolution at the plant-soil ...
WEBJun 23, 2011 — Root hairs are tip-growing extensions from root epidermal cells that play important roles in nutrient uptake and in plant-soil interactions. In this review, we discuss the major environmental, physiological and genetic factors that regulate the differentiation and growth of root hairs in angiosperms.
Through form to function: root hair development and nutrient …
WEBFeb 1, 2000 — Calcium. The tube-like growth pattern of root hairs is essential to their function in root anchorage and for increasing the area of soil exploitable by the plant 1. Root hairs form from root epidermal cells. Their development occurs in four phases: cell fate specification, initiation, subsequent tip growth and maturation (Fig. 1).
Cytoskeleton and Root Hair Growth | SpringerLink
WEBOct 29, 2010 — Root hairs are highly polarized outgrowths of a subset of root epidermis cells, the so-called trichoblasts. The biological function of root hairs is to increase the surface area of roots in order to facilitate the absorption of water and nutrients from soil.
Microtubules guide root hair tip growth - Sieberer - 2005 - New ...
WEBJul 25, 2005 — The shape of root hairs is produced by a very special form of polarized growth, called tip growth. In tip-growing cells, the actual growth process is restricted to the very tip (Derksen & Emons, 1990; Shaw et al., 2000; Dumais et al., 2004), also known as the apex or apical dome.
