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...
Climate change is driving extreme changes to the environment, posing substantial threats to global food security and bioenergy. Given the direct role of plant roots in mediating plant-environment interactions, engineering the form and function of root sy
Alternatively, if root hairs function as sensors for drought stress as recently suggested by Kwasniewski et al. (2016), this could also explain the observed differences. Is the root hair mutant rth3 showing plasticity in other root traits to compensate for the lower surface? What is the ...

Loss-of-function studies have revealed that FER is involved in many processes such as cell elongation, root hair development, responses to hormones, nutrition and plant defense (Li et al. 2016). In addition, loss-of-function studies of FER have shown defects in responses to mechanical stimuli...
Moving from the cell to the whole-organ level, we next asked if BL modulation of cell geometry is correlated with radial growth of the meristem. To address this question, radial growth of the different tissues along the meristem was quantified as a function of distance from the QC (as deter...

NO is also involved in root hairgrowth and development. The root epidermis is composed of two cell types: trichoblasts (or hair cells) and atrichoblasts (nonhair cells). InArabidopsis, as well as in lettuce, the NO scavenger cPTIO blocked the auxin-induced root hair elongation indicating tha...

Conclusion The study of root hairs and the superficial cells from which they arise has attracted many workers, partly no doubt because of their absorptive function and partly because their superficial position and relatively simple structure make them convenient for the study of cell enlargement. The...
