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.
Key words: Research prospects, root hair, Gramineae, Triticum aestivum L.
