Data from: Association of extracellular dNTP utilization with a GmPAP1-like protein in cell wall proteomic analysis of soybean roots
Plant root cell walls are dynamic systems that serve as the first plant compartment responsive to soil conditions, such as phosphorus (P) deficiency. To date, evidence for the regulation of root cell wall proteins by P deficiency remains sparse. In order to facilitate understanding of roles played by soybean (Glycine max) root cell wall proteins (CWPs) in adaptation to P deficiency, iTRAQ proteomic analysis was conducted. A total of 53 CWPs with differential accumulation in response to P deficiency were identified. Subsequent qRT-PCR analysis correlated the accumulation of 21 of 27 up-regulated proteins, and 8 of 26 down-regulated proteins with corresponding gene expression patterns in response to P deficiency. One up-regulated CWP, the purple acid phosphatase 1-like (GmPAP1-like), was functionally characterized. Bean (Phaseolus vulgaris) transgenic hairy roots overexpressing GmPAP1-like displayed increased root associated acid phosphatase activity. Plus, relative growth and P content were significantly enhanced in GmPAP1-like overexpression lines compared to control lines when dNTP was applied as the sole external P source. Taken together, it suggests that modulation of cell wall proteins possibly regulates complex root system changes in response to P deficiency, and that the cell wall localized GmPAP1-like protein is involved in extracellular dNTP utilization in soybean.
Data from: Cell wall microstructure, pore size distribution and absolute density of hemp shiv
This paper, for the first time, fully characterises the intrinsic physical parameters of hemp shiv including cell wall microstructure, pore size distribution and absolute density. Scanning Electron Microscopy revealed microstructural features similar to hardwoods. Confocal Microscopy revealed three major layers in the cell wall: middle lamella, primary cell wall and secondary cell wall. Computed tomography improved the visualisation of pore shape and pore connectivity in three dimensions. Mercury intrusion porosimetry showed the average accessible porosity was 76.67 ± 2.03 % and pore size classes could be distinguished into micropores (3-10 nm) and macropores (0.1-1 µm and 20-80 µm). The absolute density was evaluated by helium pycnometry, mercury intrusion porosimetry (MIP) and Archimedes' methods. The results show that these methods can lead to misinterpretation of absolute density. The MIP method showed a realistic absolute density (1.45 g/cm3) consistent with the density of the known constituents: including lignin, cellulose and hemi-cellulose. However, helium pycnometry and Archimedes' methods gave falsely low values due to 10% of the volume being inaccessible pores, which require sample pretreatment in order to be filled by liquid or gas. This indicates that the determination of the cell wall density is strongly dependent on sample geometry and preparation.

Rice genome-scale network integration reveals transcriptional regulators of grass cell wall synthesis
<p><span><span><span><span><span><span><span><span><span><span><span>Grasses have evolved distinct cell wall composition and patterning relative to dicotyledonous plants. However, despite the importance of this plant family, transcriptional regulation of its cell wall biosynthesis is poorly understood. To identify grass cell wall-associated transcription factors, we constructed the Rice Combined mutual Ranked Network (RCRN). The RCRN covers >90% of annotated rice (<i>Oryza sativa</i>) genes, is high quality, and includes most grass-specific cell wall genes, such as mixed-linkage glucan synthases and hydroxycinnamoyl acyltransferases. Comparing the RCRN and an equivalent <i>Arabidopsis </i>network suggests that grass orthologs of most genetically verified eudicot cell wall regulators also control this process in grasses, but some vary significantly in network connectivity between these divergent species. Reverse genetics, yeast-one-hybrid, and protoplast-based assays reveal that OsMYB61a activates a grass-specific acyltransferase promoter, which confirms network predictions and supports grass-specific cell wall synthesis genes being incorporated into conserved regulatory circuits. In addition, 10 of 15 tested transcription factors, including six novel <u>w</u>all-<u>a</u>ssociated regulators (WAP1, WACH1, WAHL1, WADH1, OsMYB13a, and OsMYB13b), alter abundance of cell wall-related transcripts when transiently expressed. The results highlight the quality of the RCRN for examining rice biology, provide insight into the evolution of cell wall regulation, and identify network nodes and edges that are possible leads for improving cell wall composition.</span></span></span></span></span></span></span></span></span></span></span></p>
