The density and length of root hairs are enhanced in response to cadmium and arsenic by modulating gene expressions involved in fate determination and morphogenesis of root hairs in Arabidopsis [PDF]
Frontiers in Plant Science, 2016 Root hairs are tubular outgrowths that originate from epidermal cells. Exposure of Arabidopsis to cadmium (Cd) and arsenic [arsenite, As(III)] increases root hair density and length.

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

Imaging of calcium gradient oscillations in plant root hairs by light sheet fluorescence microscopy [PDF]
EPJ Web of Conferences, 2023 Root hairs are a delicate single-cell system whose growth is regulated by a fine mechanism characterised by the presence of a tip-high Ca2+ gradient that shows regular oscillations in growing root hairs.

Response of in situ root phenotypes to potassium stress in cotton [PDF]
PeerJ, 2023 Potassium plays a significant role in the basic functions of plant growth and development. Potassium uptake is closely associated with morphological characteristics of the roots.

Root structure syndromes of four families of monocots in the Middle Urals
Plant Diversity, 2023 The present article tests the following general assumption: plant taxa with different specializations towards mycorrhizal interactions should have different root syndromes. Roots of 61 species common in boreal zone were studied: 16 species of Poaceae, 24

Uncovering genes and ploidy involved in the high diversity in root hair density, length and response to local scarce phosphate in Arabidopsis thaliana. [PDF]
PLoS ONE, 2015 Plant root hairs increase the root surface to enhance the uptake of sparingly soluble and immobile nutrients, such as the essential nutrient phosphorus, from the soil.

Plant Signaling & Behavior, 2011 Root hairs are single cells specialized in the absorption of water and nutrients from the soil. Growing root hairs require intensive cell-wall changes to accommodate cell expansion at the apical end by a process known as tip or polarized growth. We have recently shown that cell wall glycoproteins such as extensions (EXTs) are essential components of ...

Frontiers in Plant Science, 2021 The rice root system develops a large number of nodal roots from which two types of lateral roots branch out, large L-types and fine S-types, the latter being unique to the species. All roots including S-types are covered by root hairs.

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

Contribution of Root Hair Development to Sulfate Uptake in Arabidopsis
Plants, 2019 Root hairs often contribute to nutrient uptake from environments, but the contribution varies among nutrients. In Arabidopsis, two high-affinity sulfate transporters, SULTR1;1 and SULTR1;2, are responsible for sulfate uptake by roots.
