How a liverwort reacts to wounding: tracing the evolution of defence responses in the nonvascular plant Marchantia polymorpha New Phytol. (IF 8.3) Pub Date : 2024-06-24 Claudia Beraldo, Alessandro Alboresi
In natural environments, plants are continuously exposed to biotic and abiotic stressors that can damage their tissues. Insects feeding on xylem or phloem sap, attacks of herbivores and climate challenges are some examples of harmful events to plant integrity. The mechanical damage from these stressors leads to the loss of nutrients and water and serves as entry points for pathogens. The transmission

Putting soil microbes on first: identifying the engines of home‐field advantage in litter decomposition New Phytol. (IF 8.3) Pub Date : 2024-06-22 Ashley D. Keiser
Litter decomposition is a key pathway through which carbon (C) and nutrients are cycled from senesced plant material into soil pools. This pathway is a critical determinant of site fertility and contributes to soil C pools. Ecologists have widely measured litter decomposition to help refine patterns in C and nutrient cycling across terrestrial ecosystems. Home-field advantage (HFA) has become a prevalent
