The 17 longest read SMRT cells (P5-C3 chemistry) were used for this approach, as computational limitations prevented all 32 from being used. Characterization of LTR-Retrotransposons on Hemileia vastatrix genome. Departamento de Fitopatologia, Universidade Federal de Viçosa, Viçosa, Minas Gerais, Brazil, Roles Therefore, those five candidate effectors identified can play important function in coffee resistance to the rust pathogen. Contigs that were produced using the HGAP assembly of PacBio long-read data (Fig 1, blue boxes) were leveraged as guide reads for a subsequent assembly of Illumina short-reads using the CLC Genomic Workbench. For instance, the range of predicted CSEPs, from 659 to 775, observed by [23], is indeed dependent on the prediction program used (659 CSEPs predicted using PProwler and 775 CSEPs using SignalP) and did not considered the analysis by TargetP (for subcellular localization of proteins) and TMHMM (to discriminate soluble and membrane proteins), which would decrease the predicted number. PLoS ONE 14(4): 5. in order to survive. Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee Arabica. https://doi.org/10.1371/journal.pone.0215598.g001. and Br. Development of a Web-based information system for the search and visualization of the H. vastatrix genome. Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee Arabica. Yes tritici (385) and M. larici-populina (109). A total of 9234 transcripts were identified and annotated. Click through the PLOS taxonomy to find articles in your field. Funding acquisition, These residues confer stability to proteins in extracellular space by means of formation of intra-molecular disulfide bridges that are characterized by their importance for structure and function. The discovery of species-specific proteins and effectors is not trivial; while searches typically utilize criteria like being small and cysteine-rich to identify candidates, not all will function as effectors, and not all effectors will possess these hallmarks [54]. Characterization of LTR-retrotransposons on Hemileia vastatrix genome. The x-axis consists of protein sequences found for each GO-term in this category. The analysis performed for the hierarchical levels numbers 6 and 8, led us to confirm that as these proteins are essentially associated with the nucleus, cytosol, ribosome, mitochondria, Golgi apparatus, and endoplasmic reticulum (S2D Fig). Six effectors showed expression during the incompatible interaction with Híbrido de Timor, the majority showing expression peaks at 24 hours after inoculation followed by a decrease. Current knowledge of the H. vastatrix genome is limited and only a small fraction of the total fungal secretome has been identified. Yes Characterization of a resistance locus to coffee leaf rust (Hemileia vastratrix ) in coffee trees: genomic organization, diversity and development of tools for functional gene validation Latest: Plant-Microbe Interaction-The Good And The Bad Jinhushen Biological Acquires 67% Stake In Its Controlling Shareholder Wairarapa Water Ltd. Candidate genes in coffee (Coffea arabica L.) leaves associated with rust (Hemileia vastatrix Berk. The fungus is widespread in coffee growing regions causing significant yield losses and its chemical control can lead to increased production costs. Coffee plants are seriously affected by leaf rust (Hemileia vastatrix) and loss of resistance to emerging races is a current threat. (B) EHv33_5: the highest level of gene expression was recorded at 24 hai and, then, decreased over time. More CSEPs were highly expressed in the compatible interaction than the incompatible interaction, which is expected as the effectors play a role in manipulating host defense and contribute to disease development. Table 1. tritici (64.8 Mb), M. larici-populina (101,1Mb), and M. lini (189 Mb), have relatively smaller genomes [19] [21] [22]. No, Is the Subject Area "Genome analysis" applicable to this article? 2007 Evolution of races of Hemileia vastatrix in Colombia. (2019) Genome sequencing and transcript analysis of Hemileia vastatrix reveal expression dynamics of candidate effectors dependent on host compatibility. (B) EHv33_1: the highest level of gene expression was recorded at 24 hai and, then, decreased over time. By Wolf Psort analyses (Table 3), most of the secreted proteins had subcellular location assigned as mitochondria (241) and extracellular space (186). We are currently testing PCR amplification of 100 SSR primers that were developed from the genomic sequences to study the evolution of this pathogen in Colombia. However, a major drawback is that it is highly susceptible to Hemileia vastatrix Berkeley and Broome (1869), the coffee leaf rust pathogen. Hemileia vastatrix The most damaging pathogen of coffee is Hemileia vastatrix Berk. Besides, reference mapping of the Illumina data back to the contigs resulted in higher rates of broken read pairs (61.9%) and a low rate of reference coverage (33% of the reference did not align reads) relative to other strategies. 98 A.B. This resulted in a 547 Mb genome of H. vastatrix race XXXIII (Hv33), with 13,364 predicted genes that encode 13,034 putative proteins with transcriptomic support. No, Is the Subject Area "Genome annotation" applicable to this article? All sequencing was performed at the University of Delaware Sequencing and Genotyping Center (Delaware Biotechnology Institute, Newark, DE, USA). tritici is publicly available [19] and can be used for further detailed comparative analysis of both pathogens. The classical secretory pathway [56] delivers the majority of effector proteins of the plant pathogenic fungi described thus far. Sequences of proteins of H. vastatrix, which did not have a hit, were compared with secreted proteins described in [36, 48] using the search tools BLASTp (e-value = 10−5) and BLASTx (e-value = 10−10), as described above. In this work, a 454-pyrosequencing transcriptome analysis of H. vastatrix germinating urediniospores (gU) and appressoria (Ap) was performed and compared to previously published in planta haustoria-rich (H) data. & Br, is one of the most threatening diseases for Coffea arabica L. It is hypothesized that host tolerance to CLR relies on non-race-specific resistance genes. here. tritici may not be solely because they belong to the same order, but also because they may have a similar gene content necessary for pathogenicity and may employ a similar pathogenic process. Secreted proteins were found to be significantly similar (e-value < 10−5) to protein sequences obtained from NCBI and UNIPROT databases by using the Blast2GO bioinformatics platform. RNA-Seq from urediniospores was used to guide the de novo annotation of the H. vastatrix gene … The integrity of PCR amplification products was verified by electrophoresis in 1.2% agarose gel. To date, genomes of five important rust fungi have been published: Melampsora larici-populina (101.1 Mb, [19]), Puccinia graminis f. sp. In this study, only libraries obtained from incompatible interaction in two inoculation periods, i.e., 12 and 24 hours after inoculation were used. tritici (88.6 Mb), P. striiformis f.sp. Interestingly, mapping of the same reads to only the contigs >2000 bp resulted in a very comparable mapping rate of 94.4%. These proteins potentially represent novel genes and were considered unique to H. vastatrix, as they have not yet been described. GRASSO V.; SIEROTZKI H.; GARIBALDI A.; GISI U. Relatedness Among Agronomically important Rusts Based on Mitochondrial Cytochrome b Gene and Ribosomal ITS Sequences. Using BLASTp, none of our 615 CSEPs were found in the study by [55]. Following this, residues of cysteine and motifs characteristic of effectors, such as [YWF]xC, CxxC and CxxxC, were searched for in each secreted protein identified. Background. For many centuries, rust diseases have been a major threat to many crops, causing severe damage to farming activities. In this work, a 454-pyrosequencing transcriptome analysis of H. vastatrix germinating urediniospores (gU) and appressoria (Ap) was performed and compared to previously published in planta haustoria-rich (H) data. The proteins flagged as related to secretory pathway signal peptide (SP) were selected by TargetP version 1.0 [44]. These reads totaled >100X coverage for the expected genome size of H. vastatrix (~733.5 Mb according to [24]). These resulting scaffolds were further filled and joined using PBJelly software, and a final error polishing step mapping Illumina reads back to the improved assembly. Thus, we can infer that the following genes are effector candidates possibly translocated into host cells via haustorium: EHv33_7, EHv33_2, EHv33_10, EHv33_4 and EHv33_16. While the Hv33 genome assembly remains fragmented, it exhibited increased genome coverage, contiguity, and performs better for reference mapping of high-throughput sequencing data than the previous assembly. The largest number of proteins was associated with transferase activity, ion binding and hydrolase activity (Fig 2). No, Is the Subject Area "Plant fungal pathogens" applicable to this article? genome of H. vastatrix (c. 797 Mbp) conceals great pathological diversity, with more than 50 physiological races. Like all rust fungi, H. vastatrix is an obligate parasite that requires living host cells. This strategy is known as post-haustorial resistance [64] [10] and is usually shown after the formation of primary haustorium, which occurs about 48 hours after inoculation of H. vastatrix on coffee leaves. Besides, by CLC Genomics Workbench, the HvCat assembly were mapped using both the default read mapping settings (80% identity over 50% read length) and a higher stringency setting (90% identity over 90% read length). This low similarity can be explained by the small number of proteins of H. vastatrix available in the GenBank to date. Formal analysis, The x-axis consists of protein sequences found for each GO-term in this category. Coffee leaf rust caused by the fungus Hemileia vastatrix is the most damaging disease to coffee worldwide. Of sequences with a blast hit (e-value < 10−5), 72.2% were most similar to Puccinia graminis, 27.0% were more similar to Melampsora larici-populina, and 0.8% were most similar to sequences from H. vastatrix that had already been deposited in the databases. Similarly, assembled transcripts from another H. vastatrix race HvCat downloaded from NCBI SRA (SRR1124793; [23]; and 352,146 NCBI downloaded ESTs from H. vastatrix CIFC isolate 178a (ERR106426; [36]) were used. Some of these selected genes did not match with any other sequence in the queried databases (see methods for details) and other genes were identified as secreted protein of H. vastatrix, thus suggesting they are likely unique to H. vastatrix. We used in silico methods to predict secreted proteins, and a subset of their corresponding genes were subject to time course-based, gene expression studies. All the new findings can be useful in the development of molecular markers to distinguish races and, thus, provide a helpful tool to outperform difficulties found in the use of differential coffee cultivars. Repetitive elements were identified in 118,162 scaffolds using the Repeat Masker software [51]. No, Is the Subject Area "Gene expression" applicable to this article? The fungal suspension was obtained by adding 2 mg of urediniospores in 2.0 ml sterile microfuge tubes containing 1000 μl of sterile distilled water. PLOS ONE promises fair, rigorous peer review, In order to obtain a more comprehensive understanding of its secretome, we aimed to sequence and assemble the entire H. México, C.P. After redundancy analysis, this number dropped to 452 CSEPs (S3 Table). The Blast2GO program was used for functional clustering of 543 proteins found to be similar to sequences of proteins obtained from the NCBI and UNIPROT databases. Reference mapping of the underlying sequence data from the HvCat assembly to Hv33 resulted in 80.8% of reads mapping, while a reciprocal analysis mapping our raw data to the HvCat genome resulted in a mapping rate of 60.4%. The work is made available under the Creative Commons CC0 public domain dedication. The period of 12 hours after inoculation was used as reference sample. Another nine genes were significantly induced after haustorium formation in the compatible interaction. 2 1 Agronomy School, Instituto Tecnológico de Costa Rica, San Carlos, Alajuela, Costa Rica Closest known homologs for the predicted protein coding genes with transcriptome support from the H. vastatrix genome (Hv33) were determined using BLAST version 2.6.0 [41] to search the GenBank non-redundant database (GenBank nr) and UniProt Knowledgebase (UniProtKb) using BLASTp (e-value < 10−5). Green rectangles refer to the second assembly strategy, which included a de novo assembly using reads obtained on the Illumina platform with SOAP de novo 2 assembler and subsequently improved with 32 SMRT cells of PacBio reads using PBJelly software. The expression level of target genes was normalized by using two endogenous genes of H. vastatrix, namely, β-tubulin and CytIII. The expression level of target genes was normalized by using two endogenous genes of H. vastatrix, namely, β-tubulin and CytIII.

At the end of each reaction, a dissociation curve analysis was performed by heating the amplicon from 60 to 95°C in order to confirm the specificity of the amplification. Hemileia vastatrix Red indicates a relatively high level of up-regulated, whereas green indicates a relatively low level of up-regulation. Project administration. Coffee leaf rust caused by Hemileia vastatrix Berk & Broome is the major disease of Arabica cultivated coffees (Coffea arabica L.) (Silva et al., 2006). Roles Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee ( Coffea sp. ) This approach produced a significant number of long contigs, however they were error prone (particularly short insert/deletion) and did not cover the complete genome. C) The y-axis consists of GO-terms described in the cellular component category for the hierarchical level #3. The data were analyzed with REST software proposed by [50]. tritici proteins, whereas only 17.7% (109) are similar to M. larici-populina proteins. (Uredinales), or coffee rust. The. CLC Genomics Server version 6.0.4 (CLC bio, Aarhus, Denmark) was used for quality trimming (q<0.001 with no ambiguous nucleotides), adapter removal, and filtering of any reads shorter than 35bp. The period of 12 hours after inoculation was used as reference sample. Many effectors secreted by germinating spores are involved in signal transduction and establishment of the infection processes, in an attempt to suppress PAMP-triggered immunity (PTI), and then are recognized by plant receptors in resistant plants, triggering defense responses (effector-triggered immunity or ETI) [36] [61] [48]. Project administration, Since 2008, Colombia has been experiencing an epidemic of the coffee rust Hemileia vastatrix.The altitude range of the disease has expanded, and nursery and young plants that were usually not attacked by the disease are now significantly affected. B) The y-axis consists of GO-terms described in the biological process category for the hierarchical level #3. The RT-PCR was carried out as an initial measure of amplified products using cDNA synthesized from RNA of pathogen samples, cDNA synthesized from RNA of coffee leaf samples only, and negative control consisting of nuclease-free water. In order to obtain a more comprehensive understanding of its secretome, we aimed to sequence and assemble the entire H. vastatrix genome using two next-generation sequencing platforms and a hybrid assembly strategy. The secretome of H. vastatrix was predicted using a pipeline combining different bioinformatics approaches. Current knowledge of the H. vastatrix genome is limited and only a small fraction of the total fungal secretome has been identified. The infection process of H. vastatrix on coffee leaves starts with the germination of urediniospores on the abaxial leaf surface, formation of appressoria over a stoma and subsequent penetration, spread of penetration hypha into the substomatal chamber, and further inter and intracellular colonization. Writing – original draft, Affiliation https://doi.org/10.1371/journal.pone.0215598.g007. BUSCO was run in both genome and protein modes and using the basidiomycota_odb9 conserved genes library. The short lifespan of plant pathogenic organisms, however, makes them reproduce more often than their hosts, consequently evolving faster. Of the expected BUSCO single-copy genes, 3.7% were duplicated which is in line with or lower than four existing reference genome assemblies from other species in the order Pucciniales. and Br. Of these predicted genes, 13,364 protein coding genes could be supported by the currently available H. vastatrix transcriptomic data available with a Maker AED score less than 1. Studies involving different species responsible for leaf rusts, as P. striiformis f.sp. In this work, a 454-pyrosequencing transcriptome analysis of H. vastatrix germinating urediniospores (gU) and appressoria (Ap) was performed and compared to previously published in planta haustoria-rich (H) data. Conditions (detailed below) were created to ensure the existence of sufficient concentration of fungal suspension for successive inoculations on seedlings. Pycnial/ spermagonial and aecial stages have not been observed. Hemileia vastatrix, necrosis suppression, plant immunity, Pseudomonas syringae pv.

Coffee leaf rust caused by the fungus Hemileia vastatrix is one of the most important leaf diseases of coffee plantations worldwide. The best of these approaches as determined by criteria including N50, longest contig/scaffolds, and read mapping accuracy criteria are summarized in Fig 1, although many additional approaches were also applied. The CLC HGAP strategy was employed to take advantage of the PacBio long read data to produce long contigs (Fig 1, blue boxes). This resistance response was observed in 18% of infection sites at 17hai, reaching 65% and 93% at 24hai and 96hai, respectively [35]. Then, the predicted secretomes were clustered based on sequence similarities using OrthoVenn [47] (e-value: 10−5; inflation value: 1.5). description: Coffee rust Genome sequencing. In this study, some effector candidates showed high expression levels in susceptible genotypes from 48 to 72 hours after inoculation. The large size of the fungal nuclear genome was measured by flow cytometry, as ranging from 733.5 Mb [24] to 796.8 Mb [25]. View Category:Genomics -> Projects -> Hemileia vastatrix Genome Project The aims of this project are: 1. Final SOAP and CLC/HGAP assemblies were evaluated using these data, as well as annotation results from each. Due to the high quality of its beverage, C. arabica is the species most cultivated worldwide. After germination, urediniospores were scraped from Petri dishes, frozen in liquid nitrogen, and stored at -80°C until further processing. Núcleo de Análises de Biomoléculas, Universidade Federal de Viçosa, Viçosa, Minas Gerais, Brazil, Roles Writing – original draft, Affiliation Conceptualization, The efficiency of the cDNA synthesis process was assessed by PCR using the following reference genes: β-tubulin and Cytochrome c oxidase subunit III. Thus, the greater number of cysteine residues in an effector protein, the faster is its capacity for changes under any environmental selection pressure, thus favoring the evolution of new effectors and even new fungal physiological races.
