Tackling Conifer Needle Cast and Ash Dieback with Host-Derived Microbial Antagonists Exhibiting Plant Growth-Promoting Traits

mycolabadmin

Scientists discovered native bacteria from European ash and Scots pine trees that can fight two destructive forest diseases: ash dieback and needle cast. These bacteria not only inhibit the disease-causing fungi but also help trees grow better by improving nutrient uptake. This natural approach offers an eco-friendly alternative to fungicide sprays for protecting forests.

Controlled inoculation provides insight into western redcedar resistance to multiple root- and butt-rot pathogens

Scientists tested western redcedar trees with eight different wood-decaying fungi to understand which ones cause disease and how resistant the trees are. They used two methods to infect young trees in a greenhouse and tracked disease development over 18 months. They discovered that while some fungi caused visible damage, others caused hidden infections that still harmed tree growth even without obvious symptoms. These findings can help tree breeders develop redcedar varieties that better resist these diseases.

Researchers discovered native bacteria living in European ash and Scots pine trees that can fight two destructive forest diseases: ash dieback and needle cast. These bacteria not only inhibit pathogen growth but also help trees absorb nutrients better, making them excellent natural candidates for protecting forests without harmful chemicals. The study identified several bacterial species that showed strong disease-fighting ability, with one strain preventing needle cast fungus growth by up to 80%.

Genomic Exploration of Climate-driven Evolution and Evolutionary Convergence in Forest Pathogens

This study examined three fungal diseases that harm forests to understand how they adapt to different climate conditions. Researchers found that all three pathogens rely on similar genetic changes to adapt to wet and humid environments, despite being very different species. Using computer models, they predicted how these diseases might spread differently as climate changes in the future, which could help forest managers prepare and protect trees.
