A chromosome-level, fully phased genome assembly of the oat crown rust fungus Puccinia coronata f. sp. avenae: a resource to enable comparative genomics in the cereal rusts

bioRxiv, 2022
Advances in sequencing technologies as well as development of algorithms and workflows have made it possible to generate fully phased genome references for organisms with non-haploid genomes such as dikaryotic rust fungi.

Southern corn rust caused by Puccinia polysora Underw: a review

Phytopathology Research, 2021
Southern corn rust (SCR) caused by Puccinia polysor a Underw is one of the most devastating maize diseases, resulting in substantial yield losses worldwide. The pathogen is an obligate biotrophic parasite that is difficult to culture on artificial media.

Analysis of the transcriptomic, metabolomic, and gene regulatory responses to Puccinia sorghi in maize

Molecular plant pathology, 2021
Common rust, caused by Puccinia sorghi, is a widespread and destructive disease of maize. The Rp1‐D gene confers resistance to the P. sorghi IN2 isolate, mediating a hypersensitive cell death response (HR).

Investigation on types of corn rust in eastern Yunnan ecology and analysis of population genetic structure of its rusts

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2022
Corn rust disease can be classified into four types: common corn rust, southern corn rust, tropical corn rust and stem corn rust. In this paper, 270 samples of corn rust gathered from Yunnan province were identified by observation of symptom and pathogen

A polysaccharide deacetylase from Puccinia striiformis f. sp. tritici is an important pathogenicity gene that suppresses plant immunity

Plant Biotechnology Journal, 2020
Summary The cell wall of filamentous fungi, comprised of chitin, polysaccharide and glycoproteins, maintains the integrity of hyphae and protect them from defence responses by potential host plants.

Increased virulence of Puccinia coronata f. sp.avenae populations through allele frequency changes at multiple putative Avr loci

PLoS Genetics, 2020
Pathogen populations are expected to evolve virulence traits in response to resistance deployed in agricultural settings. However, few temporal datasets have been available to characterize this process at the population level.

Pest categorisation of Puccinia pittieriana [PDF]

EFSA Journal, 2017
The Panel on Plant Health performed a pest categorisation of Puccinia pittieriana, the causal agent of common rust of potato, for the EU. The pathogen is a single taxonomic entity and reliable methods exist for its detection and identification. Cultivated potato (Solanum tuberosum) and tomato (Solanum lycopersicum) are the main hosts of P. pittieriana.

Effect of abiotic factors on pathotypes causing yellow and brown rust in wheat

Journal of Agrometeorology, 2023
An attempt was made to determine the most favourable abiotic factors influencing germination of urediniospores of different pathotypes of Puccinia species. The causal organism of rusts in wheat is Puccinia spp.
