“…Genetic resistance to rust infection has been identified as either race-specific (also known as seedling or qualitative resistance) or non-race-specific resistance (Periyannan et al, 2017). More than 150 wheat rust resistance genes have been genetically defined in wheat or wild relatives, most conferring race-specific resistance (McIntosh et al, 1995(McIntosh et al, , 2013.…”

Wheat is one of the primary staple foods throughout the planet. Significant yield gains in wheat production over the past 40 years have resulted in a steady balance of supply versus demand. However, predicted global population growth rates and dietary changes mean that substantial yield gains over the next several decades will be needed to meet this escalating demand. A key component to meeting this challenge is better management of fungal incited diseases, which can be responsible for 15%-20% yield losses per annum. Prominent diseases of wheat that currently contribute to these losses include the rusts, blotches and head blight/scab. Other recently emerged or relatively unnoticed diseases, such as wheat blast and spot blotch, respectively, also threaten grain production. This review seeks to provide an overview of the impact, distribution and management strategies of these diseases. In addition, the biology of the pathogens and the molecular basis of their interaction with wheat are discussed.

“…Non-race-specific resistance, often referred to as adult plant resistance (APR), confers quantitative resistance against wheat rusts (Periyannan et al, 2017). In these cases, the characteristic partial resistance phenotypes limit inoculum build-up and the likelihood of the occurrence of epidemics.…”

“…Oat crown rust resistance may be mediated by race-specific or non-race-specific mechanisms (Carson, 2011;Leonard, 2002;Periyannan et al, 2017). Race-specific resistance is underpinned by the concept of the gene-for-gene interaction, which has been fundamental in the breeding of disease-resistant crop varieties (Dodds and Rathjen, 2010;Flor, 1971), and has been extensively exploited in oat breeding programmes to control crown rust since the early 1900s (Ohm and Shaner, 1992).…”

Most crown rust management strategies involve the use of rust-resistant crop varieties and the application of fungicides. The attainment of the durability of resistance against Pca is difficult as it is a highly variable pathogen with a great propensity to overcome the genetic resistance of varieties. Thus, adult plant resistance is often exploited in oat breeding programmes to develop new crown rust-resistant varieties.

“…Physical barriers, such as rigid cell walls and waxy cuticles as well as preformed antimicrobial compounds are some of the constitutive obstacles that explain why plants are immune to most microbes. Nevertheless, certain microbes have evolved strategies to overcome these barriers, and in such instances plant-microbe incompatibility is based upon pathogen recognition and the induction of plant defense responses (Heath 2000, Periyannan et al 2017).…”

Oat crown rust caused by Puccinia coronata f. sp. avenae is the most destructive foliar disease of cultivated oat. Characterization of genetic factors controlling resistance responses to Puccinia coronata f. sp. avenae in non-host species could provide new resources for developing disease protection strategies in oat. We examined symptom development and fungal colonization levels of a collection of Brachypodium distachyon and B. hybridum accessions infected with three North American P. coronata f. sp. avenae isolates. Our results demonstrated that colonization phenotypes are dependent on both host and pathogen genotypes, indicating a role for race-specific responses in these interactions. These responses were independent of the accumulation of reactive oxygen species. Expression analysis of several defense-related genes suggested that salicylic acid and ethylene-mediated signaling, but not jasmonic acid are components of resistance reaction to P. coronata f. sp. avenae. Our findings provide the basis to conduct a genetic inheritance study to examine if effector-triggered immunity contributes to non-host resistance to P. coronata f. sp. avenae in Brachypodium species.
