Abstract
Highlights • Necrotrophic pathogens are now recognized as serious threats to global wheat yield. • Genome-wide association and QTL mapping are powerful tools for effector identification. • Necrotrophic effectors now have known roles in the suppression of PAMP-triggered immunity. • The intractability of wheat is the biggest hurdle to understanding the molecular basis of these diseases. For many years pathogens of wheat have remained poorly understood. Hindered by an inaccessible host and the obligate nature of many of the pathogens, our understanding of these interactions has been limited compared to other more amenable pathosystems. However, breakthroughs over recent years have shed new light on diseases of wheat, particularly those caused by the genetically tractable necrotrophic pathogens. We now understand that many of the necrotrophic fungal pathogens do interact with wheat in a strict gene-for-gene relationship, and that pathogen and host partners in these interactions have now been identified. This improved understanding of necrotrophic effector biology has fundamentally changed the way we consider these important wheat diseases. [ABSTRACT FROM AUTHOR]
