Manganese limitations and the enhanced soil carbon sequestration of temperate rainforests
<p>Manganese (Mn) has been identified as a regulatory bottleneck in the accumulation of humus because of its role as an enzymatic co-factor in the breakdown of recalcitrant C by Mn-peroxidase (MnP). We tested this abiotic limit on decay via contrasting soils along a podzolization gradient of coastal British Columbia, where an inverse exponential relationship between soil organic carbon (SOC) and exchangeable Mn had been observed. Moderately weathered soils (Brunisols) had an average 3.6-fold increase in MnP activity within the upper soil profile in comparison to highly weathered Podzols. An ordination of the Agaricomycete fungal community, which are responsible for MnP production in soils, confirmed significant differences in assemblages across soil types for saprotrophic fungi, particularly species within the Agaricales, Trechisporales and Auriculariales. Ectomycorrhizal fungi of <i>Pseudotsuga</i> <i>menziesii</i> were equally aligned with soil type and select taxa more abundant on Brunisols may have supplemented MnP activity. A laboratory incubation with an Mn amendment produced significant interactions in MnP activity by soil type. Surprisingly, MnP activity of both Brunisol substrates declined substantially with an amendment (-56% and -40% for forest floor and mineral soil, respectively), in contrast to Podzols (-30% and +26%, respectively). This inhibitory response was linked to considerable uptake of the amendment, and underscores how Mn<sup>2+</sup> operates directly on fungi as a regulator of <i>mnp</i> transcription for MnP production. Our study highlights a new perspective concerning the abiotic drivers underpinning the large, expansive soil C stocks across perhumid temperate rainforests of the Pacific Northwest.</p>
Data from: Redox mediated carbon monoxide release from a manganese carbonyl—implications for physiological CO delivery by CORMs
<p><span>We evaluated the dynamics of hydrogen peroxide reactions with metal carbonyls. specifically a water-soluble manganese carbonyl. These files are the raw data for the quantitative mechanistic investigation of the H<sub>2</sub>O<sub>2</sub> oxidation of the water-soluble model complex <i>fac</i>-[Mn(CO)<sub>3</sub>(Br)(bpCO<sub>2</sub>)]<sup>2–</sup>, (<b>A</b>, bpCO<sub>2</sub><sup>2–</sup> = 2,2'-bipyridine-4,4'-dicarboxylate dianion). The method of intial rates was utilized in the experimental studies thus raw spectral data for the figures and results presented in RSOS-211022 were included. These data demonstrated pH-dependent kinetics. All the raw absorbance data used to determine the initial reaction rates and observed rate constant from pH 6.1-7.4, 8-32 mM [H<sub>2</sub>O<sub>2</sub>]. and 19.5- 42<sup>o</sup>C are present. For soluble homogenous experiments, UV-Vis, Fluorescence assay, and FT-IR spectral data for conditions included in the manuscript. For insoluble products of the experiments, X-ray diffraction and ICP-AES raw data are included.</span></p> <p>There are several untested hypotheses about the mechanisms of the reaction of manganese carbonyl with reactive oxygen species. We found that intracellular pH greatly influences the reaction rate and may be a control for redox-mediated CO release from mangense CORMs. Since the lysosome is more acidic and mitochondrial matrix is more basic than the cytosol it is likely different local rates of CO release would be observed. Furthermore, in considering the localization and diffusion of H<sub>2</sub>O<sub>2</sub> in biological systems, it is likely that a relatively slow reaction with manganese carbonyls (compared to catalase) can exhibit physiological effects. The cytotoxic effects of Mn(I) carbonyls have been associated with the generation of hydroxyl radicals, however we founs no appreciable quantities of hydroxyl radicals compared to known catalysts. Thus we conclude that these cytotoxic effects are more likely due to released CO interacting with heme-proteins vital to cellular respiration. Our mechanistic and kinetic findings provide literature precedence for researchers examining physiological effects of Mn(I) carbonyls.</p>
