Since root hairs can also contribute to the plant's water uptake their importance could change over the course of a growing season. It was our objective to investigate the role of root hairs under field conditions. Methods The root hair mutant rth3 of Zea mays and the corresponding wild-...
In this review, we highlight recent advancements in understanding the molecular mechanisms behind root meristem maintenance, cell differentiation, lateral root growth, root hair development, and crown root formation. Additionally, we explore how abiotic stresses such as drought, salinity, nitrate ...
Root architecture adaptions to drought stress are diversely characterized in cereals [18]. In general, drought stress under field conditions leads to an increased root-shoot ratio and tap root growth [19, 20] as well as a reduced root dry weight, volume, diameter and lateral root formation [...
water transport, secondary metabolism, and cell wall. In particular, we foundchitinases, aquaporins, terpene synthases, expansins, protein EXORDIUM, formin-like and extensin-like proteins, as well asxyloglucan endotransferases(Online Resource 4, Supplementary TableS3; ...

regulation of root meristem activity (Yang et al.2014), root cell differentiation (Tsukagoshi et al.2010), root elongation (Tsukagoshi et al.2010; Chen et al.2016; Liu et al.2016), lateral root emergence (Orman-Ligeza et al.2016), and root hair formation (Sundaravelpandian et al.2013...
In WinRhizo the automated threshold or a manual adaption of the threshold was done by choosing the tonal value with the best noise to root relation. All pixels above this value are assumed as background while all pixels below this value are considered as root. The threshold value of WinRhizo...
Our results showed an interaction effect between tree provenances and soil lithology on root surface area (RSA), root length (RL), root volume (RV), root biomass (RB), specific root surface area (SRA) and specific root length (SRL). The RV, RSA, RL, RB, and SRL of the DY provenanc...
cell-wall extention. On the right, the effect of drought or Al on cell-wall extension is shown: reduced hydration of the cell wall and Al-inhibited XET activity, and strong binding of Al to pectins and xyloglucans reduce cell-wall extensibility. Al and drought-enhanced crosslinking of cell...
(Os03t0736300 and Os04t0497200). CesA up-regulation can promote root hair elongation, thus improving the absorption of water and nutrients by roots [50,51]. Interestingly, a previous study found that high expression ofOsGLU3(Os04t0497200) can affect root cell wall cellulose synthesis and ...
