Citrus sinensis challenged with LotP

ABSTRACT: Infiltrating purified LotP protein in healthy citrus leaf induces chlorosis and provoke plant stress. Further proteomic analysis of the affected tissue using TMT11MS/MS revealed a significant abundance of plant proteins associated with stabilizing and processing mRNA transcripts and miRNAs. Interestingly, a subset of transcription factors directly connected to pathways coordinating the innate plant defense were also more abundant in the damage tissue two days post infiltration. Inhibiting the formation of LotP multimers via direct mutation of critical residues of the N terminal domain significantly decreases the chlorotic response in infiltrated leaf as well as the intensity of the associated proteome reaction.

Frontiers in microbiology 20210804

'Candidatus Liberibacter asiaticus' is known as the most pathogenic organism associated with citrus greening disease. Since its publicized emergence in Florida in 2005, 'Ca. L. asiaticus' remains unculturable. Currently, a limited number of potential disease effectors have been identified through in silico analysis. Therefore, these potential effectors remain poorly characterized and do not fully explain the complexity of symptoms observed in citrus trees infected with 'C ...[more]

Transcriptome analysis of cucumber response to nitrogen deficiency

Project description:Nitrogen is the most important mineral nutrient of plant. As a worldwide and economically important vegetable, cucumber (Cucumis sativus L.) has a strong nitrogen-dependence. We took whole transcriptome sequencing approach to compare the gene expression profiles of cucumber leaves and roots grown under sufficient or insufficient nitrate supply. Analysis of the transcriptome data revealed that the root and leaf adapt different response mechanisms to long-term nitrogen deficiency. Photosynthesis and carbohydrate biosynthetic process were pronouncedly and specifically reduced in leaf, while the ion transport function, cell wall and phosphorus-deficiency response function seem systematically down-regulated in root. Genes in nitrogen uptake and assimilation are decreased in root, but some are increased in leaf under nitrogen deficiency. Several lines of evidence suggest that the altered gene expression networks support the basic cucumber growth and development likely through successful nitrogen remobilization involving in the induced expression of genes in ABA and ethylene pathways. cucumber leaf and root mRNA of 28-day after sowing nitrogen deficiency and sufficiency deep sequencing, using Illumina HiSeq 2000

Bicarbonate induced redox proteome changes in Arabidopsis suspension cells

Project description:Climate change as a consequence of increasing atmospheric CO2 affects plant growth and productivity. CO2 is not only a carbon donor for photosynthesis but also an environmental signal that can perturb cellular redox homeostasis and lead to modifications of redox-sensitive proteins. Although redox regulation of protein functions has emerged as an important mechanism in several biological processes, protein redox modifications and how they function in plant CO2 response remain unclear. Here iodoTMTRAQ proteomics technology was employed to analyze changes in protein redox modifications in Arabidopsis thaliana suspension cells in response to bicarbonate (mimic of elevated CO2) in a time-course study. A total of 47 potential redox-regulated proteins were identified with functions in carbohydrate and energy metabolism, transport, ROS scavenging, cell structure modulation and protein turnover. This inventory of previously unknown protein redox switches in Arabidopsis thaliana bicarbonate responses lays a foundation for future research toward understanding the molecular mechanisms underlying plant CO2 responses.

Comparative proteomics of salt stressed own rooted and 110R grafted Thompson Seedless grapevines

Project description:Salt stress is a rising threat to agriculture system. The accumulation of salts near the plant roots hampers the normal uptake of water causing osmotic stress and ionic toxicity to the plant. Thompson Seedless is a popular table grape variety of Vitis vinifera L., which is sensitive to salt stress when grown on its own roots; grafting it onto a wild rootstock such as 110 Richtor (110R) makes it tolerant to salt stress. In the present study, shotgun-proteomics approach was used for the investigation of salt stress induced molecular response of own rooted and 110R grafted Thompson Seedless grapevines. A salt stress experiment was conducted on sixteen month old potted grapevines. The grapevines were treated with 150mM NaCl solution for seven days and the control vines were irrigated with tap water. The young leaf samples were collected from control and treated vines at three time-points viz. 6 hours, 48 hours and 7 days of salt stress. The stress responsive proteins identified through statistical analysis revealed a distinct response to salinity in both the vines.

Transcription profiling of E. coli BW25113 fhlAL/pCA24N-FhlA133 vs fhlA/pCA24N-FhlA in modified-complex 20 mM formate at 37A?C

Project description:Variant FhlA133 (Q11H, L14V, Y177F, K245R, M288K, and I342F) had eight- fold higher hydrogen production than FhlA wild-type under 30 min of anaerobic incubation in modified-complex 20 mM formate at 37ÂºC. The mechanism by which the FhlA133 mutations increase hydrogen production is by increasing the transcription of all of the genes activated by the native FhlA (FHL complex). Experiment Overall Design: Strains: E. coli BW25113 fhlA/pCA24N-FhlA wild-type and E. coli BW25113 fhlA/pCA24N-FhlA133 (Q11H, L14V, Y177F, K245R, M288K, and I342F). Experiment Overall Design: Medium: Modified-complex 20 mM formate Experiment Overall Design: 1 mL of overnight culture in modified - complex 20 mM formate + Cm 30 Âµg/mL was inoculated in 9 mL of fresh modified - complex 20 mM formate + Cm 30 Âµg/mL and incubated anaerobically at 37oC in 27 mL glass vials.

Broad Kinase Inhibition Mitigates Early Neuronal Dysfunction in Tauopathy

Project description:Tauopathies are a group of more than twenty known disorders that involve progressive neurodegeneration, cognitive decline, and pathological tau accumulation. Current therapeutic strategies provide only limited, late-stage symptomatic treatment. This is partly due to lack of understanding of the molecular mechanisms linking tau and cellular dysfunction, especially during the early stages of disease progression. In this study, we treated tau transgenic mice with a multi-target kinase inhibitor to identify novel targets that contribute to cognitive impairment and exhibit therapeutic potential. Drug treatment significantly ameliorated brain atrophy and neuronal function as determined by behavioral testing and a sensitive imaging technique called manganese-enhanced magnetic resonance imaging (MEMRI) with quantitative R1 mapping. Surprisingly, these benefits occurred despite unchanged hyperphosphorylated tau levels. To elucidate the mechanism behind these improved cognitive outcomes, we performed quantitative proteomics to determine the altered protein network during this early stage in tauopathy and compare this model with the human AD proteome. We identified a cluster of preserved pathways shared with human tauopathy with striking potential for broad multi-target kinase intervention. We further report high confidence

Unveiling grapevine-Plasmopara viticola dynamics through a combined analysis of leaf and apoplast proteome modulation at 6 hours of interaction

Project description:Plant apoplast is the first hub of plant-pathogen communication. Indeed, during interaction, pathogen effectors are recognized by plant defensive proteins and cell receptors and several signal transduction pathways are activated. Within this first contact, a defence response is triggered by the plant involving several extra and intracellular proteins. In grapevine, little is known about the communication between cells and apoplast in the context of plant-pathogen interactions, also apoplast dynamics, particularly considering the role of apoplastic proteins in response to pathogens still remains a blackbox. In this study we focused on 6 hours after Plasmopara viticola inoculation to evaluated grapevine proteome modulation both in the apoplastic fluid (APF) and total leaf tissue. Plasmopara viticola secretome was also assessed enabling a deeper understanding of plant and pathogen communication. Our results showed that oomycete recognition, plant cell wall modifications, ROS signalling and disruption of oomycete structures are triggered in Regent after P. viticola inoculation. Also, our results highlight a strict relation between the apoplastic pathways modulated and the proteins identified in ‘Regent’ total leaf proteome. On the other hand, P. viticola proteins related to growth/morphogenesis and virulence mechanisms were the most predominant. This pioneer study highlights the early dynamics of extra and intracellular communication between grapevine and defence activation leading to the successful establishment of an incompatible interaction

Transcription profiling of Arabidopsis Pwer::GFP protoplasts with over-expressed dominant negative mutant isoforms of Aux/IAA transcription factors

Project description:Transient genetic modification of plant protoplasts is a straightforward and rapid technique for the analysis of numerous aspects of plant biology. One drawback in the analysis of transformed protoplast suspensions is that they are a heterogeneous mix of cells that have and have not been successfully transfected. To overcome this problem, we have developed a system that employs a fluorescent positive selection marker in combination with flow cytometric analysis as well as fluorescence activated cell sorting (FACS) to isolate responses in the transfected protoplasts exclusively. This recombinase-compatible system enables high-throughput screening of genetic circuitry. Moreover, the use of FACS allows in depth downstream analysis. Lastly, over-expression is an effective means to dissect regulatory networks, especially where redundancy exists. Here, this system has been applied to the study of auxin signaling in order to investigate reporter gene activation and genome-wide transcriptional changes in response to manipulation of the auxin-response network. We have transiently over-expressed dominant negative mutant isoforms of Aux/IAA transcription factors (IAA7mII and IAA19mII; Tiwari et al., 2001) in Arabidopsis Pwer::GFP root protoplasts, making use of a RFP fluorescent positive selection marker and FACS to isolate the dually labeled (IAAnmII expressing and Pwer::GFP-positive) cells. We have compared the transcriptional differences between an empty vector control, IAA7mII and IAA19mII protoplasts that had either been treated with 5microM IAA or mock-treated for 3 hours. Experiment Overall Design: 18 samples with 3 replicates for each condition and transformation vector: 3x empty vector mock treated, 3x empty vector IAA treated, 3x IAA7mII over-expressor mock treated, 3x IAA7mII over-expressor IAA treated, 3x IAA19mII over-expressor mock treated and 3x IAA19mII over-expressor IAA treated.
