Advances in root hairs in Gramineae and Triticum aestivum

Abstract

Relevant literatures in the past ten years showed that lots of research activities have been conducted in diverse 
aspects of root hairs, in particular, of the model plant, Arabidopsis thaliana. However, data on Gramineae root hairs 
are unsystematic. Much more research activities have been done theoretically than practically, and qualitatively than 
quantitatively. There are few studies relating active, quantitative and precise regulation and control of root hairs. 
With regards to wheat root hairs, literatures are insufficient. Particularly, data concerning the kinetics of formation, 
morphology and structure of root hairs in situ in the actual wheat production are still lacking. Future research need 
to be conducted before we could actively control development and improve physiological functions of wheat root 
hairs. Moreover, although careful observations found a hairy structure named ‘special root hair’ on the basal portion 
of a nodal root in wheat, little is known about its morphology, structure, among others.
