Understanding metabolic interactions and successive cross-feeding in native microbiomes illuminates the mechanisms behind plant disease promotion and suppression, enhancing our ability to manipulate microbiomes toward specific functions of interest.

New archaeobotanical data from Negev Highland rubbish middens demonstrate that crop diversity in the Southern Levant expanded more during the first millennium CE than in any earlier period, yet with minimal consequences for consumption and production patterns.

Major neuron classes are activated when the fly walks, whether it chooses or is forced to do so.

Preimplantation screening of embryos using polygenic risk scores may substantially reduce risk for a given complex disease, but this effect depends on several quantifiable factors and raises significant ethical issues.

Flowers did bloom in the Early Jurassic.

The first crystal structure of an active plant asparaginyl endopeptidase reveals a tetrahedral intermediate state in its active site, which may help to explain why these enzymes have been independently recruited to perform peptide macrocyclization.

Identification of two arbuscular mycorrhiza-specific lipid biosynthesis mutants and fatty acid transfer experiments reveal that host plant lipids are transferred to symbiotic fungi and needed for their development.

Phylogenetic and biochemical analyses reveals a shared evolutionary path between biosynthesis and transport of defense metabolites in plants.
