Hemileia vastatrix is a fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease that is devastating to susceptible coffee plantations. The H. vastatrix monopustular isolate Hv-02, characterized as race XXXIII, was used in this work. Reference mapping of the approximately 260 million Illumina reads (130M read pairs) back to this genome assembly result in a 95.3% mapping rate. 2006. Cristancho, MA; Escobar C; Ocampo JD. Following quality screening, 5.73 Gbp comprised of 920,326 long-reads were obtained. Data were recorded at 12, 24, 48 and 72 hours after inoculation. Diniz et al [63] found similar result to our prior cytological observations and suggested that this rapid plant defense response, which prevents haustorium formation, may be the basis for durable resistance to races of this fungal species. In the basidiomycete fungi, U. maydis, and some Hemileia vastatrix isolates, genome size varies between 20 and 610 Mb (Kämper et al., 2006; http://bioinformatics.cenicafe.org/index.php/wiki/Genome_Size-Chromosome_Number). Illumina data from this study, and the 454 sequence data (NCBI SRA: SRR833265, SRR833266 –quality trimmed as previously described but to q>0.05) used to generate the previously existing genome assembly (HvCat) (NCB: GCA_003057935.1) [23], were mapped to the Hv33 assemblies. here. https://doi.org/10.1371/journal.pone.0215598.g004. Hemileia vastatrix HvCat : Hemileia vastatrix HvCat Genome sequencing Dataset . From this putative secretome, 111 proteins were identified as candidate effectors (EHv33) unique to H. vastatrix, and a subset consisting of 17 EHv33 genes was selected for a temporal gene expression analysis during infection. Funding acquisition, Affiliation As part of the Cenicafe Coffee Genome Project we are studying the coffee rust, Hemileia vastatrix. For many centuries, rust diseases have been a major threat to many crops, causing severe damage to farming activities. Long known in coffee-growing areas of Africa, the Near East, India, Asia, and Australasia, coffee rust was discovered in 1970 to be widespread in Brazil, the first known infected area in the Western Hemisphere. Current knowledge of the H. vastatrix genome is limited and only a small fraction of the total fungal secretome has been identified. https://doi.org/10.1371/journal.pone.0215598.t002.

Instituto Agronômico de Campinas, Centro de Citricultura “Sylvio Moreira”, Cordeirópolis, São Paulo, Brazil, Roles Construction of the first draft of the H. vastatrix genome. Analysis of methods for the estimation of genome size and chromosome number in the coffee rust. tritici (64.8 Mb), M. larici-populina (101,1Mb), and M. lini (189 Mb), have relatively smaller genomes [19] [21] [22]. The 111 (39+72) CSEPs of H. vastatrix were annotated using the Pfam software and no function has been assigned to them. Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee Arabica. Methodology, Affiliation Item Preview This project is in collaboration with scientists from Universidad de los Andes in Bogota and is financed by Colciencias-Renata. In addition, 39 protein sequences showed similarity with previously deposited sequences from H. vastatrix, and 72 returned no results, indicating their uniqueness to the H. vastatrix race XXXIII genome. The first library was sequenced using 15 Single Molecule Real Time (SMRT) cells and combinations of two chemistries, namely, XL-C2 (11 SMRT) and P4-C2 (4 SMRT). Yes GOUVEIA M., M.C. https://doi.org/10.1371/journal.pone.0215598.s002. (2019) Genome sequencing and transcript analysis of Hemileia vastatrix reveal expression dynamics of candidate effectors dependent on host compatibility. Losses reported by the coffee institutes for the 2012-2013 harvest in Central America Over the past 10 years, advances in Next Generation Sequencing (NGS) technologies and decreasing sequencing costs allowed an increase in the number of sequenced genomes, especially of plant pathogenic fungi causing important diseases in major agricultural crops. Another factor aggravating this disease is that the fungus has been able to overcome the resistance of recently released cultivars and has more than 50 physiological races described globally [3] [4]. Fungal structures can develop at different times depending on the host genotype. 8 Characterization of incomplete resistance to Hemileia vastatrix in the Icatu coffee population. In this way, the presence of the rust virulent race XXXIII in the field may impose a serious threat to any coffee orchard worldwide. Mycologia, 97: 396-404. Conditions (detailed below) were created to ensure the existence of sufficient concentration of fungal suspension for successive inoculations on seedlings. Characterization of LTR-retrotransposons on Hemileia vastatrix genome. The combined use of a single monopustular isolate and long read sequencing (PacBio) in our approach was fundamental for obtaining this assembled genome with a higher level of contiguity (N50 = ~10.0 kb; Table 1), than the previous assembly of HvCat genome (N50 = ~1.6 kb; total genome 330 Mbp [23]). Formal analysis, Spores were uniformly spread on polyethylene Petri dishes containing a thin layer of agar and water. The Illumina HiSeq platform produced 264,721,502 short-reads. CEGMA analysis found that 96.4% of expected core genes were found in the genome, while BUSCO identified 91.7% (13.1% fragmented) of expected single copy genes (from 1335 conserved Basidiomycota proteins) in the protein annotations (S1 Fig). The best results, were achieved by a hybrid de novo genome assembly approach (Fig 1, red boxes). B) The y-axis consists of GO-terms described in the biological process category for the hierarchical level #3. Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee Arabica. 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. Three technical replicates for each of three existing biological replications for each sample (resistant plants and susceptible plants) were performed at the following four time-points: 12, 24, 48, and 72 hours after inoculation (hai). The resulting set of scaffolds from both the SOAP de novo assembly and the HGAP/CLC Hybrid assembly were further joined and gaps were filled using PacBio long read data in PBJelly (v14.1.14; [29] in conjunction with the BLASR mapping tool ([30]; options: -minMatch 8 -minPctIdentity 70 -bestn 10 -nCandidates 20 -maxScore -500). This resistance response was observed in 18% of infection sites at 17hai, reaching 65% and 93% at 24hai and 96hai, respectively [35]. (Uredinales), or coffee rust. A total of 9234 transcripts were identified and annotated. Overview of the functional virulent genome of the coffee leaf rust pathogen Hemileia vastatrix with an emphasis on early stages of infection. We further analyzed whether the putative secreted proteins of H. vastatrix race XXXIII contained other effector-like sequences for the presence of cysteine residues, which are indicative signs of secretion in other plant pathogens. 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. Conceptualization, These proteins potentially represent novel genes and were considered unique to H. vastatrix, as they have not yet been described. In Brazil, previous studies differentiated 15 races named as I, II, III, VII, X, XIII, XV, XVI, XVII, XXII, XXIII, XXIV, XXV or XXXI, XXXIII, and XXXVII [3]. Germination and penetration studies on coffee rust (Hemileia vastatrix Berk & Br.). Dissertação de mestrado defendida na Universidade Federal de Viçosa. 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. HvCat refers to H. vastatrix isolate (GCA_003057935.1); Mp: Melampsora larici-populina 98AG31 (GCF_000204055.1); Ml: Melampsora lini CH5 (JGI Genome portal: https://genome.jgi.doe.gov/Melli1/Melli1.info.html); Pg: Puccinia graminis f. sp. Thus, they can be used as markers to identify resistant genotypes in coffee breeding programs. In this study, a survey of physiological races of Hemileia vastatrix was carried out on 34 coffee leaf rust populations collected at several coffee genotypes in Brazil. 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. It comprises 42 species occurring mainly in tropical to sub-tropical regions of Africa and Asia, mostly on uncultivated Rubiaceae and Apocyna-ceae plants (Ritschel, 2005). 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 … Euphytica 32: In press . Yes Having large genomes does not mean having more genes, as genome expansion may occur not only by acquisition of new genes, but also by increasing repetitive regions or by transposable element proliferation during the evolutionary process [52]. Annotation systems. For Illumina sequencing, approximately 10 μg of DNA from germinated urediniospores (protocol described above and the same material used for the PacBio sequencing) was used to construct four libraries and sequenced with paired-end 151 bp reads. Coffee plants are seriously affected by leaf rust (Hemileia vastatrix) and loss of resistance to emerging races is a current threat. Departamento de Fitopatologia, Universidade Federal de Viçosa, Viçosa, Minas Gerais, Brazil, Roles The aims of this project are: 1. 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. Overview of the functional virulent genome of the coffee leaf rust pathogen Hemileia vastatrix with an emphasis on early stages of infection. A) The y-axis consists of GO-terms described in the molecular function category for the hierarchical level #3. Overall, all these identified genes, pre- and post-haustorial candidate effectors, can be exploited to assist breeding programs, as biotechnological tools (effectoromics). Coffee plants are seriously affected by leaf rust (Hemileia vastatrix) and loss of resistance to emerging races is a current threat. Multiple strategies were tested for the hybrid genome assembly for the dual-platform sequencing, the most successful strategies are outlined in Fig 1. 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. Yes 3. A deep knowledge of the mechanisms of pathogenicity is necessary for better understanding the plant resistance mechanisms, particularly because the Coffea spp. Cristancho, MA; Escobar C 2008 Transferability of SSRs markers from related Uredinales species to the coffee rust (Hemileia vastatrix). 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. Interestingly, mapping of the same reads to only the contigs >2000 bp resulted in a very comparable mapping rate of 94.4%. While this indicates that these proteins may function as effectors, functional characterization assays are needed to decipher the molecular role of these proteins in pathogenesis and/or on pathogen fitness. Current knowledge of the H. vastatrix genome is limited and only a small fraction of the total fungal secretome has been identified. Departamento de Fitopatologia, Universidade Federal de Lavras, Lavras, Minas Gerais, Brazil, Roles R proteins encoded by resistance genes can recognize some of these effector proteins and thus trigger plant defense responses [17] [18]. Coffee leaf rust caused by Hemileia vastatrix Berk & Broome is the major disease of Arabica cultivated coffees (Coffea arabica L.) (Silva et al., 2006).

This assembly also did not validate well as it produced fewer annotated gene calls than other assemblies, a higher number of missing (20.2%) and fragmented (19.8%) conserved single-copy genes (BUSCO). 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. It is interesting to speculate that these effectors might play a role in defense and recognition by cognate R genes in the plant, however further experimentation is required to fully understand their functions. 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.

A functional clustering analysis was performed by using the Blast2GO program for 11,466 protein sequences found to be significantly similar (e-value < 10−5) to those obtained from GenBank and Uniprot databases. Six of these genes were significantly expressed in the incompatible interaction (Fig 4) and nine were expressed in the compatible interaction (Fig 5 and Fig 6). We have obtained around 500,000 genomic 454 sequences from H. vastatrix clustered in 45,224 contigs by Newbler assembler. tritici (88.6 Mb), P. striiformis f.sp. Only 39 sequences from the predicted secretome had similarity to the public sequences of H. vastatrix. 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. Candidate genes in coffee (Coffea arabica L.) leaves associated with rust (Hemileia vastatrix Berk. Construction of the first draft of the H. vastatrix genome. 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. No, Is the Subject Area "Transposable elements" applicable to this article? On the other hand, if the pathogen overcomes the pre-haustorial resistance, the resistant plants will likely delay fungal growth in early stages of infection. BUSCO was run in both genome and protein modes and using the basidiomycota_odb9 conserved genes library. Genome-wide analyses of these rusts revealed a large catalog of secreted proteins, some of which are candidate effectors. Discover a faster, simpler path to publishing in a high-quality journal.

H. vastatrix Sequencing Our study identified about 82% of scaffolds contained repetitive elements, from which 43.6% consisted of transposable elements (Table 2). Rust, caused by the biotrophic fungus Hemileia vastatrix, is the main disease of coffee, and is widely distributed in producing regions. C) The y-axis consists of GO-terms described in the cellular component category for the hierarchical level #3. Then, the predicted secretomes were clustered based on sequence similarities using OrthoVenn [47] (e-value: 10−5; inflation value: 1.5). 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. Microscopic observations in the pathosystem Híbrido de Timor and H. vastatrix race XXXII revealed that cytological responses induced by the fungus can be observed in stomatal cells by 17 hours after infection (hai) and corresponded to hypersensitive-like cell response. But those numbers drop to 452 after redundancy analysis. The period of 12 hours after inoculation was used as reference sample. and Br. The genome size of most rust species is unknown due, in part, to technical constraints, especially the difficulty in accessing spores to extract the nuclei for cytometry. Evaluation of algorithms for the characterization of the spatial distribution of H. vastatrix populations in Colombia. Biological Control 49(2):114-119. PacBio long reads were also independently assembled using the PacBio SMRT Portal HGAP algorithm (versions 1 and 2; [28]), with version 2 performing best.
