Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

open access: yesIbis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

open access: yesJournal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.
