Manganese (Mn) oxides are among the strongest oxidants and sorbents in the environment, and Mn(II) oxidation to Mn(III/IV) (hydr)oxides includes both abiotic and microbially-mediated processes. While white-rot Basidiomycete fungi oxidize Mn(II) using laccases and manganese peroxidases in association with lignocellulose degradation, the mechanisms by which filamentous Ascomycete fungi oxidize Mn(II) and a physiological role for Mn(II) oxidation in these organisms remain poorly understood. Here we ...[more]

Interplay between manganese and zinc homeostasis in the human pathogen Streptococcus pneumoniae

Project description:ICP-MS analysis of Streptococcus pneumoniae D39 reveals a high cell-associated manganese (Mn(II)) concentration that is comparable to that of zinc (Zn(II)). Stressing these cells with 100-200 µM Zn(II) leads to a slow-growth phenotype and a reduction in total Mn(II) concentration, with no decrease in the concentrations of other metal ions. Supplementation of the growth media with as little as 10 µM Mn(II) fully restores wildtype growth patterns and normal levels of cell-associated Mn(II). DNA microarray analysis reveals that zinc stress induces the expected upregulation of czcD (encoding a zinc effluxer), but also a pleiotropic transcriptional response suggestive of mild cell wall stress. Genes encoding a nitric oxide detoxification system (nmlR) and the Mn(II) uptake system (psaABC) are also induced. We conclude that Zn(II) toxicity results in a cytoplasmic Mn(II) deficiency, possibly caused by competition at the Mn(II) uptake transporter protein PsaA.

The hierarchy of transition metal homeostasis: Iron controls manganese accumulation in a unicellular cyanobacterium.

Project description:Iron and manganese are part of a small group of transition metals required for photosynthetic electron transport. Here, we present evidence for a functional link between iron and manganese homeostasis. In the unicellular cyanobacterium, Synechocystis sp. PCC 6803 Fe and Mn deprivation resulted in distinct modifications of the function of the photosynthetic apparatus. For example, iron limitation modifies the rate of QA re-oxidation in photosystem II, a complex that contains more Mn than Fe. The intracellular elemental quotas of Fe and Mn are also linked. Fe limitation reduces the intracellular Mn quota. Mn limitation did not exert a reciprocal effect on Fe quotas. Microarray analysis comparing Mn and Fe limitation revealed a stark difference in the extent of the transcriptional response to the two limiting conditions, reflective of the physiological data. The effects of Fe limitation on the transcriptional network are widespread while the effects on Mn limitation are highly specific. Our analysis also revealed an overlap in the transcriptional response of specific Fe and Mn transporters. This overlap provides a framework for explaining Fe limitation induced changes in Mn quotas. Fe transporters can serve as a low affinity Mn transport system. Under iron limitation the specificity of the Fe transport system changes, making it a less efficient Mn transport system.

Comparative transcriptome analysis of manganese transportation in different leaves in soybean under manganese stress

Project description:Manganese (Mn) stress is known to be a major limitation for development of soybean, and legume crop productivity globally. However, very little information is available on the adaptive mechanisms, particularly in the important legume crop soybean (Glycine Max L.), which enable leaves to respond to high-Mn availability. Thus, to elucidate these mechanisms in soybean leaves at molecular level, we used an RNA sequencing approach to investigate transcriptomes of the leaves under Mn-sufficient and Pi-excessive conditions. Our investigation revealed that more genes showed altered expression patterns in old leaf than in young leaf under Mn excess, suggesting that the Mn excess-more-sensitive old leaf required expression change in a larger number of genes to cope with high-Mn stress than the Mn excess-less-sensitive young leaf. The functional classification of differentially expressed genes (DEGs) was examined to gain an understanding of how leaves respond to Mn stress, caused by soil Mn excess. As a result, more DEGs involved in nodulation, detoxification, nutrient/ion transport, transcriptional factors, key metabolic pathways, Mn remobilization and signalling were found in Mn-excessive induced old leaves than in Mn-excessive induced young leaves. Our findings have enabled the identification of molecular processes that play important roles in the acclimation of leaves to Mn excess, ultimately leading to the development of Mn-efficient soybean suitable for Mn-excessive soils.

Shotgun proteomics of Mn (II)-oxidizing Serratia marcescens

Project description:In order to gain insight into how bacteria respond to manganese (II) and relate to oxidation, the shotgun proteomics approach was applied to a potential Mn (II) oxidizing Serratia marcescens strain cultivated in the absence and presence of Mn (II). The LG1 strain, which grew equally well in these two conditions, presented a set of proteins related to the cellular processes vital to its survival and proteins that ensured its good adaptation and tolerance to Mn (II). The multicopper oxidase CueO was identified, indicating its probable participation in the Mn (II) bio-oxidation, but its expression was not modulated by the presence of Mn (II).Through these findings, we reiterate the ability of LG1 to be applied successfully in the bioremediation of Mn (II) environments and the efficiency of the shotgun approach in obtaining the first total shotgun proteome of this specie.

Manganese detoxification by Staphylococcus aureus

Project description:Manganese (Mn) is an essential micronutrient critical for the pathogenesis of Staphylococcus aureus, a significant cause of human morbidity and mortality. Paradoxically, excess Mn is toxic, therefore maintaining intracellular Mn homeostasis is required for survival. To identify gene candidates that contribute to manganese detoxification, we compared the transcriptional response of S. aureus cells exposed to 1 mM MnCl2 and those that were untreated.

Defective mitochondrial dynamics underlie manganese-induced neurotoxicity

Project description:Rats were exposed to manganese (Mn) at 25mg/kg for 15 days. After the exposure, the RNA was collected from the striatum tissue (specific part the brain) of the control group (untreated) and Mn-exposed group, and submitted for RNA sequencing to elucidate the transcriptional changes of Mn-induced toxicity in the striatum.

Stylosanthes guianensis-LC-MS - Physiological responses and proteomic changes reveal insights into Stylosanthes response to manganese toxicity

Project description:Manganese (Mn), an essential element for plants, can be toxic when present in excess. Stylo (Stylosanthes) is a pioneer tropical legume with great potential for Mn tolerance, but its Mn tolerance mechanisms remain poorly understood. In this study, the mechanisms underlying stylo response to Mn toxicity were investigated using two stylo genotypes with contrasting Mn tolerance. Results showed that stylo genotype RY5 exhibited Mn tolerance superior to that of genotype TF2001, showing lower reductions in leaf chlorophyll concentration, maximum quantum yield of photosystem II (Fv/Fm) value and plant dry weight under Mn toxicity. Furthermore, RY5 tolerance to Mn toxicity could be attributed to stimulation of antioxidant protection and regulation of Mn homeostasis. Subsequently, a label-free quantitative proteomic analysis was conducted to investigate the protein profiles in the leaves and roots of stylo in response to Mn toxicity. A total of 356 differentially expressed proteins (DEPs) were identified, including 206 proteins from leaves and 150 proteins from roots, which consisted of 71 upregulated, 62 downregulated, 127 strongly induced and 96 completely suppressed proteins. These DEPs were mainly involved in defense response, photosynthesis, carbon fixation, metabolism, cell wall modulation and signaling. The qRT-PCR analysis verified that 10 out of 12 corresponding gene transcription patterns correlated with their encoding proteins after Mn exposure. Furthermore, stylo plants coped with Mn toxicity may be through enhancement of defense response and phenylpropanoid pathway, adjustment of metabolic process, and modulation of protein synthesis and turnover. Taken together, this study increases our understanding of tropical legume responses to Mn toxicity.
