Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

PLANTS, PEOPLE, PLANET, EarlyView.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...
