Rust in peace: breeding and cultural practices to mitigate rust diseases in crops and forest trees

Описание: CPS Workshop: Thursday, June 9 , 2022
Among the 8,000 rust species described, many are known for their devastating impact on field crops and forest trees, challenging global food security and ecosystems health. Due to their biotrophic nature and the complexity of their lifecycle, rust fungi are challenging organisms to work with. However, with advancements in genetics and then genomics, significant progress in the identification of resistance and avirulence genes has been made in rust pathosystems since Harold H. Flor first demonstrated the molecular basis of the gene-for-gene hypothesis in 1947. This workshop follows up from the Special Issue on rust disease management and biology in the Canadian Journal of Plant Pathology published in December 2021. We will highlight and discuss some of the recent advances in resistance breeding and management practices for the mitigation of rust disease of field crops and forest trees.
