Exploring pathogenic microRNAs of rice sheath blight pathogen

Project description:We constructed seven small RNA libraries of Rhizoctonia solani AG1 IA and sequenced using Illumina GA II. The seven samples include mycelium cultured on PDA without rice incubated, 6 different stages at 10 hours (10h), 18h, 24h, 32h, 48h and 72h spanning the Rhizoctonia solani AG1 strains infection rice. We identified miRNA-like small RNAs (milRNAs) using MIREAP and mirdeep2. The milRNAs were used for further analysis of interactions between milRNA and mRNA that may involve in plant-infection.

Evolution and Pathogenic Mechanism of Rice Sheath Blight Pathogen

Project description:Analysis of RNA expression of Rhizoctonia solani AG1 IA. mRNA-seq of R. solani AG1 IA at 6 timepoints during the plant infection were sequenced. Cufflinks was used for calculating expected fragments per kilobase of transcript per million fragments sequenced (FPKM) values. Expression and regulation were identified. Analysis provides suggestion for discovering novel effectors and understanding pathogen factors.

Expression data in whole Arabidopsis seedlings after treatment with Rhizoctonia solani AG8 and AG2-1

Project description:Rhizoctonia solani is an economically important soil-borne necrotrophic fungal pathogen, with a broad host range and for which little effective resistance exists in crop plants. Arabidopsis is resistant to the R. solani AG8 isolate but susceptible to R. solani AG2-1. Affymetrix microarray analysis was performed to determine genes that are affected in common and specifically by AG8 and AG2-1. 3 biological samples were taken from 3 treatments: non-infected control, R. solani AG8 infection and R. solani AG2-1 infection.

Differentially expressed genes during the potato-Rhizoctonia solani AG3 interaction

Project description:Differential analysis of the potato-Rhizoctonia solani AG3 interaction. Samples were extracted from R. solani inoculated potato sprouts at two time points. R. solani is one of the most prominent fungal pests of potato and therefore of great economic relevance.

The pangenome analysis of the soil-borne fungal phytopathogen Rhizoctonia solani and development of a comprehensive web resource: RsolaniDB

Project description:Rhizoctonia solani Kühn is a soilborne basidiomycetous fungus that causes significant damage to many economically important crops. R. solani isolates are classified into 13 Anastomosis Groups (AGs) with interspecific subgroups having distinctive morphology, pathogenicity and wide host range. However, the genetic factors that drive the unique fungal pathology are still not well characterized due to the limited number of available annotated genomes. Therefore, we performed genome sequencing, assembly, annotation and functional analysis of 13 R. solani isolates covering 7 AGs and selected subgroups (AG1-IA, AG1-IB, AG1-IC, AG2-2IIIB, AG3-PT, AG3-TB, AG4-HG-I, AG5, AG6, and AG8). Here, we report a pangenome comparative analysis of 13 R. solani isolates covering important groups to elucidate unique and common attributes associated with each isolate, including molecular factors potentially involved in determining AG-specific host preference. Finally, we present the largest repertoire of annotated R. solani genomes, compiled as a comprehensive and user-friendly database, viz. RsolaniDB. Since 7 genomes are reported for the first time, the database stands as a valuable platform for formulating new hypotheses by hosting annotated genomes, with tools for functional enrichment, orthologs and sequence analysis, currently not available with other accessible state-of-the-art platforms hosting Rhizoctonia genome sequences.

Rhizoctonia solani AG8 infection of wheat seedling roots

Project description:Rhizoctonia solani is a nectrotrophic fungal pathogen that causes billions of dollars of damage to agriculture worldwide and infects a broad host range including wheat, rice, potato and legumes. In this study we identify wheat genes that are differentially expressed in response to the R. solani isolate, AG8-1, using microarray technology. A significant number of wheat genes identified in this screen were involved in ROS production and redox regulation. Levels of ROS species were increased in wheat root tissue following R. solani infection as determined by NBT, DAB and titanium sulphate measurements/stainings. Pathogen/ROS related genes from R. solani were also tested for expression patterns upon wheat infection. TmpL, a R. solani gene homologous to a gene associated with ROS regulation in Alternaria brassicicola, and OAH, a R. solani gene homologous to oxaloacetate acetylhydrolase which has been shown to produce oxalic acid in Sclerotinia sclerotiorum, were highly induced in R.solani when infecting wheat. We speculate that the wheat germin-like protein (GLP) is induced to inactivate the oxalic acid that is produced by the R. solani OAH.

RNA-seq of Medicago truncatula A17 and the ethylene insensitive sickle mutant interacting with the fungal root pathogen, Rhizoctonia solani AG8

Project description:This study compares the response of wild type (A17) and ethylene insensitive mutant (sickle) lines of the model legume Medicago truncatula to infection by the root-infecting necrotrophic fungal pathogen, Rhizoctonia solani AG8 (WAC10335). Two time points were taken, 2 and 7 days after inoculation along with corresponding mock-treated controls.
