Proteome-wide analysis of cysteine reactivity in Arabidopsis associated with biotic stress response

ABSTRACT: We used a method for the enrichment of proteins with oxidative post-translational modifications that enabled the comprehensive identification and label-free quantification of reversibly oxidized thiols across the plant proteome. The redoxomes were characterized in wild-type and the top1top2 null mutants in the early stages of effector-triggered immunity.

A surge in the accumulation of oxidants generates shifts in the cellular redox potential during early stages of plant infection with pathogens and activation of effector-triggered immunity (ETI). The redoxome, defined as the proteome-wide oxidative modifications of proteins caused by oxidants, has a well-known impact on stress responses in metazoans. However, the identity of proteins and the residues sensitive to oxidation during the plant immune response remain largely unknown. Previous studies ...[more]

Proteome responses of Grapevine to Downy mildew

Project description:A comparative proteomic analysis of grapevine leaves from the resistant genotype V. davidii ‘LiuBa-8’ (LB) and susceptible genotype V. vinifera ‘Pinot Noir’ (PN) at 12 hpi was conducted to understand the complex relationship between grapevine and P. viticola and the molecular mechanisms between difference resistant vitis genotypes at the early stage of infection. A total of 444 and 349 differentially expressed proteins (DEPs) were identified in LB and PN respectively at 12 hpi by iTRAQ. MapMan analysis showed that the majority of these DEPs were related to photosynthesis, metabolism, stress and redox. More up-expressed DEPs involved in photosynthesis and less down-expressed DEPs involved in metabolism contribute to the resistance in LB. PR10.2, PR10.3, HSF70.2 and HSP90.6 are proposed to be key proteins in both compatible and incompatible interactions. Accumulation H2O2 established the ROS signaling in incompatible interaction and APXs, GSTs maybe associated with the resistance of grapevine against downy mildew. Moreover, we verified four proteins to ensure the accuracy of proteome data using PRM. Overall, these data provide new insights into molecular events and provide valuable candidate proteins that could be used to illuminate molecular mechanisms underlying the incompatible and compatible interaction in early stage and eventually to be exploited to develop new protection strategy against downy mildew in grapevine.

Application of data-independent acquisition approach to study the proteome dynamics of plant pathogenesis responses

Project description:Plants and pathogens are entangled in a continual arms race. The plants are evolved to have a dynamic defense and immune mechanisms to resist the infection and enhance the immunity for the second wave attacks from the same or different type of pathogenic species. Not only in the evolutionally or physiologically, the plant-pathogen interaction is also highly dynamic in the molecular level. Recently, the emerging quantitative mass spectrometry-based proteomics approach, data-independent acquisition (DIA), was developed for the analysis of proteome in a high throughput fashion. In this study, the DIA approach was applied to quantitatively trace the change of the plant proteome from the early to late stage of pathogenesis progression. This study revealed that the early stage of the pathogenesis response, the proteins directly related to the chaperon for the defense proteins. In the later stage, not only the defense proteins but also a set of the pathogen associate molecular pattern triggered immunity (PTI), effector triggered immunity (ETI) related proteins were highly induced. Our finding showed the dynamics of the regulation in protein level and demonstrated that the potential of using DIA approach for tracing the dynamics of the plant proteome during pathogenesis responses.

Ontogenic Resistance in Apple

Project description:Ontogenic scab resistance in apple leaves and fruits is a horizontal resistance against the plant pathogen VenturiaM- inaequalis and is expressed as decrease of disease symptoms and incidence with the ageing of the leaves. Several studies at biochemical level tried to unveil the nature of this resistance, however without any conclusive results. We decided therefore to investigate the genetic origin of this phenomenon by performing a full quantitative trascriptome sequencing and comparison of young (susceptible) and old (ontogenic resistant) leaves, infected or not with the pathogen. Two time points at 72 and 96 hours post inoculation were chosen for RNA sampling and sequencing. Comparison between the different conditions (young and old leaves, inoculated or not) should allow finding genes differentially expressed which may represent different induced plant defense reaction leading to ontogenic resistance or be the cause for a constitutive (not inoculated with the pathogen) shift toward resistance in old leaves. Differentially expressed genes were then characterized for their function by homology to A.M- thaliana and other plantsM-^R genes, particularly looking for genes involved in pathways already suspected of appertaining to ontogenic resistance in apple or other hosts, or to plant defense mechanisms in general.

Proteomics of non-host response in barley

Project description:Nonhost resistance, a resistance of plant species against all nonadapted pathogens, is considered the most durable and efficient immune system in plants. To increase our understanding of the response of barley (Hordeum vulgare L.) plants to infection by powdery mildew, Blumeria graminis f. sp. Tritici, we used quantitative proteomic analysis (LC-MS/MS). We compared the response of two genotypes of barley cultivar Golden Promise, wild type (WT) and plants with overexpression of phytoglobin (previously hemoglobin) class 1 (HO), which has previously been shown to significantly weaken non-host resistance. A total of 8804 proteins were identified and quantified, out of which the abundance of 1044 proteins changed significantly in at least one of the four comparisons (‘i’ stands for ‘inoculated’)- HO/WT and HOi/WTi (giving genotype differences), and WTi/WT and HOi/HO (giving treatment differences). Among these differentially abundant proteins (DAP) were proteins related to structural organization, disease/defense, metabolism, transporters, signal transduction and protein synthesis. More proteins changed in abundance in WT than in HO after inoculation and most DAP increased in abundance.

RNAs expression profiling in a resistant and a susceptible grapevine cultivar to Plasmopara viticola

Project description:Plasmopara viticola (Berk. and Curt.) Berl. and de Toni is the agent of the destructive disease known as grapevine downy mildew, for the control of which intensive fungicide treatments are required. Natural sources of resistance are available in several wild Vitis species, which are being used in traditional breeding approaches. However, molecular switches, signals and effectors involved in resistance are poorly understood. In this paper we report a microarray analysis of early transcriptional changes associated to P. viticola infection in both susceptible Vitis vinifera and resistant Vitis riparia plants (12 and 24 h post inoculation). To provide a biological basis to the choice of time points for transcriptome analyses, we performed microscopic examinations of infected tissues at 12, 24, 48 and 96 hpi. Data suggest that resistance in V. riparia is mainly a post-infectional event and involves a large reprogramming of host metabolism. Transcripts of signal transduction-related genes are specifically and often strongly accumulated in response to infection. Well known defence genes also show marked transcript increases, especially pathogenesis-related proteins PR-10 and stylbene synthases, and genes related to an hypersensitive reaction. On the other hand, V. vinifera mounts a much weaker transcriptional response, involving mainly defence genes, not effective enough in preventing pathogen infection. Leaves from one resistant (V. riparia cv. Gloire de Montpellier) and one susceptible (V.vinifera cv. Pinot Noir) grapevine cultivars grown in vitro were infected with the oomycete Plasmopara viticola, and transcriptome changes were investigated at 12h and 24h after infection. Three biological replicates were considered and each hybridization was performed twice. One color labeling was performed

Transcription profiling of Arabidopsis response to Erysiphe orontii infection - AtGenExpress

Project description:AtGenExpress: A multinational coordinated effort to uncover the transcriptome of the multicellular model organism Arabidopsis thaliana; The activity of genes and their encoded products can be regulated in several ways, but transcription is the primary level, since all other modes of regulation (RNA splicing, RNA and protein stability, etc.) are dependent on a gene being transcribed in the first place. The importance of transcriptional regulation has been underscored by the recent flood of global expression analyses, which have confirmed that transcriptional co-regulation of genes that act together is the norm, not the exception. Moreover, many studies suggest that evolutionary change is driven in large part by modifications of transcriptional programs. An essential first step toward deciphering the transcriptional code is to determine the expression pattern of all genes. With this goal in mind, an international effort to develop a gene expression atlas of Arabidopsis has been underway since fall 2003. This project, dubbed AtGenExpress, is funded by the DFG, and will provide the Arabidopsis community with access to a large set of Affymetrix microarray data. As part of this collaboration, we have generated expression data from 80 biologicaly different samples in triplicate. Responses to E. orontii infection were assayed in wild-type Col-0 plants at 6, 12, 18, 24, 48, 72, 96, and 120 hours after inoculation of adult leaves. Inoculation was done via settling tower, using 10 day old E. orontii cultures. Leaves number 7 to 10 were selected for profiling.
