Novel applications of the tomato microbiome: Roles and considerations for agriculture, human health, and society

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants, like humans, have a microbiome that helps them grow, defend themselves against pathogens, acquire nutrients, and protect themselves against environmental stresses. The microbiome of tomatoes, a staple crop grown worldwide, could be utilized not only to reduce fertilizer and pesticide applications, but also to clean up harmful pollutants ...

An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

open access: yesPest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...
