root hair and non-hair cells (Kim & Dolan, 2011;Marzec, Melzer, & Szarejko, 2013). InA. thaliana,ROOT HAIRLESS SIX LIKE(RSL) class I basic helix-loop-helix transcription factors generate root hair formation competency in specific cell files and activate RSLclass II genes, which are ...
differentiated hairy root culture may be preferred as an alternative to undifferentiatedcell suspension culture. This method has some advantages: (i) high efficiency, (ii) applicability to large-scale reactor systems, (iii)geneticand biochemical stability and (iv) phytohormone-independent rapid growth....
root hair - thin hairlike outgrowth of an epidermal cell just behind the tip; absorbs nutrients from the soil prop root - a root that grows from and supports the stem above the ground in plants such as mangroves bark - tough protective covering of the woody stems and roots of trees and ...
The root hair mutant rth3 of Zea mays and the corresponding wild-type were grown for two years under field conditions on sand and loam. Results Shoot growth and P and K uptake of the plants were promoted by the presence of hairs at all growth stages. Differences between genotypes were grea...

Tip growth of plant root hairs is basic and deceptively simple.Asingle cell has awall that is cylindricalwith a prolate spheroid as an end cap. The growth takes place in the end cap. The mechanical loading whichdrives the growth consists of turgor pressure of magnitude 5鈥 10 atmospheres.A...
Even a simple property, such as the soil thickness, can range from a few centimetres to many metres, depending on the intensity and duration of weathering, episodes of soil deposition and erosion, and the patterns of landscape evolution. Nevertheless, in spite of this variability, soils have a...
Simple SynComs have already demonstrated potential utility in the field, exhibiting greater stability and performance on plants compared to single-strain inoculations132. In contrast, the top-down approach aims to modify the metagenome of entire native communities, capturing as much natural diversity ...
or combing and inadvertent snagging.) A telogen root (Fig. 8), without a sheath, indicates that the hair fell out naturally. If the root is not present, an even break with regular edges indicates that it was cut off, and an irregular break generally means that the hair was broken off....
Pi deprivation attenuates primary root growth via the coordination of rapid cessation of cell elongation (<2 h) in the transition zone [50••] and progressive inhibition of cell division (<2 days) in the RAM [51••] (Figure 1). Continued Pi limitation stimulates root hair formation...
