Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

open access: yesNew Phytologist, EarlyView.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Genetic and Phenotypic Diversity of European Triticale: GWAS of Yellow Rust Resistance and Agronomic Traits

open access: yesPlant Breeding, EarlyView.
ABSTRACT Triticale (x Triticosecale Wittmack) is an interspecific hybrid of wheat and rye. It is a promising grain and forage crop that thrives in poorer soils and low‐input farming systems. It can serve as a viable alternative to traditional small grains such as wheat and barley, bringing diversity to crop rotations and enhancing biodiversity in ...

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

open access: yesPlant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.
