Systems-wide analysis of manganese deficiency-induced changes in gene activity of Arabidopsis roots

ABSTRACT: In this study, we undertook a comprehensive quantitative proteomic profiling of Arabidopsis roots from plants grown on Mn-deplete media, aiming at dissecting and cataloging the responses of Arabidopsis roots to Mn deficiency. We used LC-Q Exactive Orbitrap mass spectrometer to compile a near complete inventory of the Arabidopsis root proteome. We identified several novel components of cellular Mn homeostasis and show that many putatively important changes in response to Mn deficiency are only evident at one of the omics levels under investigation.

Manganese (Mn) is pivotal for plant growth and development, but little information is available regarding the strategies that evolved to improve Mn acquisition and cellular homeostasis of Mn. Using an integrated RNA-based transcriptomic and high-throughput shotgun proteomics approach, we generated a comprehensive inventory of transcripts and proteins that showed altered abundance in response to Mn deficiency in roots of the model plant Arabidopsis. A suite of 22,385 transcripts was consistently ...[more]

Arabidopsis col and rglg iron deficiency response

Project description:To dissect the mechanisms that control and mediate cellular iron homeostasis, we conducted quantitative high-resolution iTRAQ proteomics and microarray-based transcriptomic profiling of iron-deficient Arabidopsis thaliana plants. Proteomic and transcriptomic profiling of Arabidopsis Col and RING DOMAIN LIGASE1 (RGLG1) and RING DOMAIN LIGASE2 (RGLG2) double mutation in response to iron deficiency were conducted. This integrative analysis provides a detailed catalog of post-transcriptionally regulated proteins and allows the concept of a chiefly transcriptionally regulated iron deficiency response to be revisited.

RNA-seq of mutant Mycobacterium neoaurum producing steroid intermediates compared with wild-type strain

Project description:Mycobacterium neoaurum (Mn), an efficient sterol consumer, has been modified to transform sterols to produce valuable steroid intermediates, which can be widely used as precursors in the synthesis of steroid hormones.To deepen our understand of the underlying mechanisms of Mn to the in vitro and in vivo environment during growth on a critical carbon source of sterol and accumulation of valuable steroid intermediates, transcriptome studies were performed to characterize the differences between wide-type Mn and various mutant Mn strains for steroid accumulation. Totally, five Mn strains were investigated, including wide-type Mn ATCC25795 cultured without (Mn-C) and with sterol addition (Mn-CC), mutant Mn ATCC25795 strains producing 9OHAD (Mn-9OHAD), ADD (Mn-ADD), and 1,4-HBC (Mn-HBC), respectively.

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. We monitored the gene expression of Synechocystis PCC6083 at standard conditions and after 2 days of iron limitation (0Fe), manganese limitation (0Mn) and combined iron and manganese limitation (0Fe0Mn). Each timepoint and condition was sampled in triplicates. Due to strong deviations in one of the three repeats for the 0Mn and 0Fe0Mn conditions, the corresponding replicates were excluded from further analysis.

Identification of novel target antigens in Membranous Nephorphathy

Project description:Membranous nephropathy (MN) is an autoimmune kidney disease with the clinical hallmark of causing high level proteinuria. MN is caused by circulating antibodies binding to targeting antigens on the surface of podocytes â€“ specialized endothelial cells contributing to the formation of the glomerular filtration barrier. Histomorphologically MN is characterized by a deposition of IgG along the glomerular basement membrane (GBM) â€“ predominantly IgG4 in primary MN â€“ as well as an accumulation of the respective target antigen, thickening of the GBM and effacement of podocyte foot processes. The predominant MN target antigen in 70-80% of MN patients is the phospholipase A2 receptor 1. Additional target antigens, which occur with lower frequencies, have recently been described. The aim of the study was the identification of a novel MN target antigen, which fulfills the typical criteria of MN target antigen: being a podocytic membrane protein, which is recognized by IgG4 subclass specific autoantibodies. Performing a mass spectrometry analysis based on a TMT-based relative quantification approach of immunoprecipitated samples resulted in the identification of Netrin G1 (NTNG1) as a novel MN target antigen. The results were validated using immunohistochemistry, Western Blot and ELISA. The molecular characterization of patients with MN will allow a better diagnosis and clinical management of these patients in the future.

Comparative Qualitative Phosphoproteomics Analysis Identifies Shared Phosphorylation Motifs and Associated Biological Processes in Flowering Plants

Project description:In this work we carried out a comparative bioinformatics analysis of pre-existing phosphoproteomics data in the public domain: PXD000033 and PXD000421 (Arabidopsis. thaliana) and PXD002222 and PXD000923 (O. sativa; rice). The aim of the analysis was to profile two model species representing the largest subclasses in flowering plants the dicot Arabidopsis thaliana and the monocot Oryza sativa, to understand the extent to which phosphorylation signaling and function is conserved across evolutionary divergent plants. From data set re-analysis, we identified 6,537 phosphopeptides from 3,189 phosphoproteins in Arabidopsis and 2,307 phosphopeptides from 1,613 phosphoproteins in rice. The relative abundance ratio of serine, threonine, and tyrosine phosphorylation sites in rice and Arabidopsis were highly similar: 88.3: 11.4: 0.4 and 86.7: 12.8: 0.5, respectively. In addition, tyrosine phosphorylation shows features different from those of the serine and threonine phosphopeptides and was found to be more frequent in doubly-phosphorylated peptides in Arabidopsis. We identified protein sequence motifs in the two species to explore the similarities, finding nineteen pS motifs and two pT motifs that are shared in rice and Arabidopsis; among them are five novel motifs that have not previously been described in both species. The majority of shared motif-containing proteins were mapped to the same biological processes with similar patterns of fold enrichment, indicating high conservation of these pathways. We also identified shared patterns of crosstalk between phosphoserines with motifs pSXpS, pSXXpS and pSXXXpS, where X is any amino acid, in both species indicating this is an evolutionary conserved signaling mechanism in flowering plants.

Single cell RNA-sequencing of polyA tailed RNA from mutant SOD1 and isogenic control human motor neurons

Project description:Amyotrophic Lateral Sclerosis is a fatal neurodegenerative disorder that affects motor neurons (MN). We used single cell RNA-seq of degenerating human MN derived from ALS patients to understand molecular drivers of MN degeneration. Patient-derived iPSC bearing a point mutation in the SOD1 gene (SOD1 E100G) were differentiated into MN. MN derived from CRISPR-Cas9 corrected isogenic control iPSC (SOD1 E100E) were used as control. Survival analysis indicated that at 44 days of in vitro differentiation, ALS MN dislpayed survival deficits. At this point, cells were harvested for single cell transcriptomics using the Fluidigm C1 system.
