A novel root hair mutant, srh1, affects root hair elongation and reactive oxygen species levels in wheat. [PDF]

Front Plant Sci
BackgroundRoot hairs are single-celled projections on root surfaces, critical for water and nutrient uptake. Here, we describe the first short root hair mutant in wheat (Triticum aestivum L.), identified in a mutagenized population and termed here short ...

Regulation of Phytohormones on the Growth and Development of Plant Root Hair

Frontiers in Plant Science, 2022
The tubular-shaped unicellular extensions of plant epidermal cells known as root hairs are important components of plant roots and play crucial roles in absorbing nutrients and water and in responding to stress.

Root hair‐specific expansins modulate root hair elongation in rice [PDF]

Plant Journal, 2011
SummaryRoot hair growth requires intensive cell‐wall modification. This study demonstrates that root hair‐specific expansin As, a sub‐clade of the cell wall‐loosening expansin proteins, are required for root hair elongation in rice (Oryza sativaL.). We identified a gene encodingEXPA17(OsEXPA17) from a rice mutant with short root hairs.

Glucose-TOR Signaling Regulates Root Hair Elongation in <i>Arabidopsis</i> via the RHD6-RSL4 Transcriptional Cascade. [PDF]

Plants (Basel)
Root hairs are tubular protrusions of root epidermal cells that expand the root surface area to facilitate water and nutrient uptake. The target of rapamycin (TOR) kinase has been identified as a positive regulator of root hair elongation, and the RHD6 ...

Drought-induced SlCLE10 coordinates ethylene biosynthesis and root hair development to enhance osmotic stress tolerance in tomato. [PDF]

Plant Commun
CLAVATA3/EMBRYO SURROUNDING REGION-related (CLE) peptides are key regulators of cell division in root, shoot, and vascular meristems. However, their roles in the regulation of root hair growth remain poorly understood.

Plant elicitor Peptides regulate root hair development in Arabidopsis. [PDF]

Front Plant Sci
Plant Elicitor Peptides (Peps) induce plant immune responses and inhibit root growth through their receptors PEPR1 and PEPR2, two receptor-like kinases. In our study, we found a previously unknown function of Peps that enhance root hair growth in a PEPRs-

Evolution and genetics of root hair stripes in the root epidermis [PDF]

Journal of Experimental Botany, 2001
Root hair pattern develops in a number of different ways in angiosperm. Cells in the epidermis of some species undergo asymmetric cell divisions to form a smaller daughter cell from which a hair grows, and a larger cell that forms a non-hair epidermal cell. In other species any cell in the epidermis can form a root hair.

Cytokinin signaling is involved in root hair elongation in response to phosphate starvation. [PDF]

Plant Signal Behav
Root hair, single-celled tubular structures originating from the epidermis, plays a vital role in the uptake of nutrients from the soil by increasing the root surface area.

Characterization of Root Hair Curling and Nodule Development in Soybean-Rhizobia Symbiosis. [PDF]

Sensors (Basel)
Soybean plants form symbiotic nitrogen-fixing nodules with specific rhizobia bacteria. The root hair is the initial infection site for the symbiotic process before the nodules.

SUPRA-PHYSIOLOGICAL LEVELS OF GIBBERELLINS / DELLAS ALTER THE PATTERNING, MORPHOLOGY AND ABUNDANCE OF ROOT HAIRS IN ROOT TIPS OF ARABIDOPSIS THALIANA SEEDLINGS [PDF]

Journal of Plant Development, 2021
In spite of the role of gibberellins/DELLAs in leaf hair production, no investigations have assessed their function in the production of root hairs. To this aim, the effects of supra-physiological levels of GAs/DELLAs on the gene expression patterning of
