The document discusses the roles of the phytohormones auxin and ethylene in promoting root hair elongation in Arabidopsis thaliana. Through genetic and physiological studies, it was found that mutants deficient in auxin or ethylene response exhibit significantly shorter root hairs, indicating that both hormones are essential for normal root hair development. The study also highlights the effects of synthetic auxin (2,4-D) and ethylene precursor (ACC) treatments on root hair length, demonstrating their positive regulatory roles. Overall, the findings suggest a complex interaction between auxin and ethylene in regulating root hair elongation.

Can ethylene stimulate arabidopsis hypocotyl elongation in the light?

Ethylene inhibits hypocotyl elongation in etiolated Arabidopsis seedlings. However, when Arabidopsis was grown in the light in the presence of ethylene or its precursor 1-aminocyclopropane-1-carboxylic acid (ACC), a marked induction of hypocotyl elongation occurred.

Does ethylene promote root growth and root hair formation?

Ethylene promotes root hair growth through coordinated EIN3/EIL1 and RHD6/RSL1 activity in Arabidopsis | PNAS.

What gives rise to root hairs?

The root hairs are thus preceded at the root tip by the zone of cell division (where cell division takes place as the root grows) and the zone of elongation (where cells and tissues elongate as the root pushes through the soil). Root hairs (orange) are an extension of the epidermis of plant roots.

What is the hormonal control of root development?

The fundamental role of auxin-mediated signaling in controlling all major aspects of root growth, from cell division, differentiation, and elongation, can be visualized, as well as the antagonistic regulation of auxin by cytokinins, and secondary regulation by other hormones, including ABA, ethylene, GA,

Does auxin promote root elongation?

The hormone auxin is known to inhibit root elongation and to promote initiation of lateral roots. Here we report complex effects of auxin on lateral root initiation in roots showing reduced cell elongation after auxin treatment.

What promotes root hair development?

Root hairs are an extensive structure of root epidermal cells and are critical for nutrient acquisition, soil anchorage, and environmental interactions in sessile plants. The phytohormone ethylene (ET) promotes root hair growth and also mediates the effects of different signals that stimulate hair cell development.

What hormone promotes root hair development?

Ethylene. The gaseous hormone ethylene is a positive regulator of root hair development, and frequently found to functionally interact with auxin signalling (Dubois et al., 2018).

Which hormone promotes root growth?

Auxin (indole-3-acetic acid, IAA), produced in young shoot organs, promotes root development and induces vascular differentiation.
