<p><span><span><span><span><span><span><span><span><span><span><span>Litter-decomposing Agaricales play key role in terrestrial carbon cycling, but little is known about their decomposition mechanisms. We assembled datasets of 42 gene families involved in plant-cell-wall decomposition from seven newly sequenced litter decomposers and 35 other Agaricomycotina members, mostly white-rot and brown-rot species. Using sequence similarity and phylogenetics, we split the families into phylogroups and compared their gene composition across nutritional strategies. Subsequently, we used Raman spectroscopy to examine the ability of litter decomposers, white-rot fungi, and brown-rot fungi to decompose crystalline cellulose. Both litter decomposers and white-rot fungi share the enzymatic cellulose decomposition, whereas brown-rot fungi possess a distinct mechanism that disrupts cellulose crystallinity. However, litter decomposers and white-rot fungi differ with respect to hemicellulose and lignin degradation phylogroups, suggesting adaptation of the former group to the litter environment. Litter decomposers show high phylogroup diversity, which is indicative of high functional versatility within the group, whereas a set of white-rot species shows adaptation to bulk-wood decomposition. In both groups, we detected species that have unique characteristics associated with hitherto unknown adaptations to diverse wood and litter substrates. Our results suggest that the terms white-rot fungi and litter decomposers mask a much larger functional diversity.</span></span></span></span></span></span></span></span></span></span></span></p>
Class-A penicillin binding proteins do not contribute to cell shape but repair cell-wall defects
Cell shape and cell-envelope integrity of bacteria are determined by the peptidoglycan cell wall. In rod-shaped Escherichia coli, two conserved sets of machinery are essential for cell-wall insertion in the cylindrical part of the cell: the Rod complex and the class-A penicillin-binding proteins (aPBPs). While the Rod complex governs rod-like cell shape, aPBP function is less well understood. aPBPs were previously hypothesized to either work in concert with the Rod complex or to independently repair cell-wall defects. First, we demonstrate through modulation of enzyme levels that aPBPs do not contribute to rod-like cell shape but are required for mechanical stability, supporting their independent activity. By combining measurements of cell-wall stiffness, cell-wall insertion, and PBP1b motion at the single-molecule level, we then present evidence that PBP1b, the major aPBP, contributes to cell-wall integrity by repairing cell wall defects.

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.
