Transcriptome-wide Association study identifies putative Elicitors/Suppressor of Puccinia graminis f. sp. tritici that Modulate Barley rpg4-mediated Stem Rust Resistance

Project description:Transcriptomic profiling was done on barley samples incoulated with different Puccinia graminis f. sp. tritici (Pgt) isolates of varying virulence profile on barley stem rust resistance gene rpg4/5 and Rpg1. Several differentally expressed host and pathogen genes were identified while comparing gene expression profiles between group of samples inoculated with isoaltes of varying virulence. Several variants with genes of pathogen were idnetified that are possibly associated with virulence to rpg4/5.

Gene expression analysis of four conditions for Puccinia graminis f. sp. tritici

Project description:Puccinia graminis f. sp. tritici is the cause of wheat stem rust. A microarray was designed from genes predicted from the P. graminis f. sp. tritici genome assembly, and gene expression measured for four conditions which include wheat or barley infecting growth stages initiated by urediniospores. mRNA was prepared from fresh urediniospores, uredinospores germinated for 24 hr, wheat seedlings infected with urediniospores for 8 days, and barley seedlings infected with urediniospores for 8 days. The asexual uredinial infection cycle on wheat produces additional urediniospores, which can start new cycles of wheat infection and are readily spread by aerial transport. This expression data is further described in Duplessis et al, Obligate Biotrophy Features Unraveled by the Genomic Analysis of the Rust Fungi, Melampsora larici-populina and Puccinia graminis f. sp. tritici

A three-dimensional chromatin contact map of Puccinia graminis f.sp. tritici

Project description:Puccinia graminis f.sp. tritici (Pgt), the causal agent of stem rust disease in wheat, is one of the most destructive pathogens and can cause severe yield losses. Here, we utilize Hi-C sequencing technology to scaffold and phase the haplotypes for the genome assembly of a US Pgt isolate 99KS76A-1.

Transcription analysis by RNAseq of adult wheat after inoculation with Puccinia graminis f. sp. tritici

Project description:The RNA sequencing analysis was undertaken to investigate the transcriptomic changes in adult wheat inoculated with Puccinia graminis f. sp. tritici the causal agent of stem rust disease. The project firstly aims to compare gene expression in one susceptible wheat line with two wheat lines exhibiting adult plant resistance to the stem rust. Secondly, the project aims to examine the temporal changes in gene expression in wheat after inoculation. Wheat plants was grown until maturity under greenhouse conditions. Plants were inoculated with Puccinia graminis f. sp. tritici and the flag leaf sheath sampled for RNA sequencing. The project aims to give essential insight into the adult plant resistance response in wheat to Puccinia graminis f. sp. tritici inoculation.

Dynamic Reconfiguration of Switchgrass Proteomes in Response to Rust (Puccinia novopanici) Infection

Project description:Switchgrass (Panicum virgatum) can be infected by the rust pathogen (Puccinia novopanici) resulting in lowering biomass yields and quality. Here, two cultivars with divergent rust resistance were used to evaluate the dynamic changes in proteomes following rust inoculation. Label-free quantitative proteomics was conducted on leaf extracts harvested from a susceptible cultivar Summer at 7, 11, and 18 DAI, and leaves collected at 18 DAI from controls and infected plants of the more resistant cultivar Kanlow.
