NO is also involved in root hair growth and development. The root epidermis is composed of two cell types: trichoblasts (or hair cells) and atrichoblasts (nonhair cells). In Arabidopsis, as well as in lettuce, the NO scavenger cPTIO blocked the auxin-induced root hair elongation indicating...
RABA2 and RABA3 also mark the distinctive domain on the TGN in non-dividing cells, and accumulate on the extending edges of the cell plates in dividing root cells (Chow et al.2008). Lines of evidence suggest that plants use secretory and recycling machineries to deliver cell wall materials ...
PI4Kβ at the TGN is required for polarized secretion of cell wall components during root hair growth [[77]]. Another effector of RABA4b is the E3 ligase PUB13 (PLANT U-BOX13), which binds GTP-bound RABA4b and PI4P and is required for ligand-induced degradation of FLS2 (FLAGELLIN ...
The Organic Foods Production Act (OFPA), which is a title of the 1990 Farm Bill, intended to set national standards for the production and handling of foods and fibers labeled as organic. Therefore the National Organic Program (NOP) was set up, which was to establish these national standards...
and found that they were mainly enriched in developing xylem and hair cells. This distribution was notably modified in the subset of differentially expressed genes with phloem pole-associated pericycle and lateral root initials being the cell populations where a significant part of the changes occurred...
90 s. Eight microliters of the reaction buffer was subjected to SDS-PAGE and blotted using biotinylated AAL (Vector Labs, cat# B-1395) with a dilution of 1:1000 and HRP-labeled Streptavidin (Sangon, cat# B110053) with a dilution of 1:5000 as the primary and secondary antibodies, ...
Therefore, plants have evolved mechanisms to maximize Pi accessibility/availability, such as increased root hair growth, lateral root branching, and induction of phosphate transporters and phosphatases [29]. Certain phosphate starvation-induced genes have evolved to release phosphate from plasma membranes ...
[4,33,42]. In previous studies, 90 of the 126 AtMYBs were grouped into 25 subfamilies. However, the remaining 36 genes were not included in the phylogenetic analysis because of low statistical support. To compare our results with these previous studies, we labeled the clades previously ...
Given the key importance of the root hair length to the extent of the P depletion zone and P acquisition (see also Chapter 12), such an enhancing effect of AM on P uptake is to be expected. In mycorrhizal plants, P uptake rate per unit root length can be 2-3 times higher than in ...
TF target genes are labeled on the right. Clusters specific to flower-, root-, leaf- or seed- related tissues are highlighted. Representative of enriched GO terms for the highlighted clusters are indicated. b Genome browser views of tissue-specific chromatin accessibility at the four chosen gene...
