Live Imaging of Root Hairs
(Springer, 2015)
Root hairs are single cells specialized in the absorption of water and nutrients. Growing root hairs requires intensive cell wall changes to accommodate cell expansion at the apical end by a process known as tip growth. ...
Abscisic acid and nitric oxide modulate cytoskeleton organization, root hair growth and ectopic hair formation in Arabidopsis
(Academic Press Inc Elsevier Science, 2018-11)
Abscisic acid (ABA) and nitric oxide (NO) are two plant growth regulators that participate in many signaling cascades in different organs all along the plant life. Here, we were interested in deciphering the effects of ABA ...
High auxin and high phosphate impact on rsl2 expression and ros-homeostasis linked to root hair growth in arabidopsis thaliana
(Frontiers Research Foundation, 2018-08)
Root hair size determines the surface area/volume ratio of the whole roots exposed to the nutrient and water pools, thereby likely impacting nutrient and water uptake rates. The speed at which they grow is determined both ...
Nitric oxide is essential for vesicle formation and trafficking in Arabidopsis root hair growth
(Oxford University Press, 2012-03)
The functions of Nitric Oxide (NO) in processes associated to root hair growth in Arabidopsis were analyzed. NO is located at high concentrations in the root hair cell files at any stage of development. NO is detected ...
Knock-down of arabidopsis PLC5 reduces primary root growth and secondary root formation while overexpression improves drought tolerance and causes stunted root hair growth
(Oxford University Press, 2018-10)
Phospholipase C (PLC) is a well-known signaling enzyme in metazoans that hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP 2) to produce inositol 1,4,5-trisphosphate and diacylglycerol as second messengers involved in ...
Auxin and Cellular Elongation
(American Society Of Plant Biologist, 2016-03)
Auxin is a crucial growth regulator in plants. However, a comprehensive understanding of how auxin induces cell expansion is perplexing, because auxin acts in a concentration- and cell type-dependent manner. Consequently, ...
A genome-wide association scan in admixed Latin Americans identifies loci influencing facial and scalp hair features
(Springer Nature, 2016)
We report a genome-wide association scan in over 6,000 Latin Americans for features of scalp hair (shape, colour, greying, balding) and facial hair (beard thickness, monobrow, eyebrow thickness). We found 18 signals of ...
Autocrine regulation of root hair size by the RALF-FERONIA-RSL4 signaling pathway
(Wiley Blackwell Publishing, Inc, 2020-02)
Root hair (RH) size has vital physiological implications, since it influences the surface area of the root and thus the ability of the plant to absorb water and nutrients from the soil. Arabidopsis ROOT HAIR DEFECTIVE ...
RSL4 Takes Control: Multiple Signals, One Transcription Factor
(Elsevier, 2017-05)
Root hair growth dramatically expands the root surface area, thus facilitating water and nutrient uptake. Until recently, the molecular mechanism underlying root hair growth was unknown. Recent studies have revealed that ...
The Root Hair Specific SYP123 Regulates the Localization of Cell Wall Components and Contributes to Rizhobacterial Priming of Induced Systemic Resistance
(FRONTIERS MEDIA SA, 2016-07)
Root hairs are important for nutrient and water uptake and are also critically involved the interaction with soil inhabiting microbiota. Root hairs are tubular-shaped outgrowths that emerge from trichoblasts. This polarized ...
