ATG8 is a well-characterized protein involved in autophagy that binds to the double-membrane enclosed phagophore. In a new preprint, Julian et al. explore their finding that ATG8 binds to the single-membrane enclosed vacuolar membrane (tonoplast). They observed that this binding is enhanced by treatments…

Cannabis sativa, also known as hemp or marijuana, is a widely cultivated plant for a variety of reasons. It is perhaps best known as a producer of an intoxicating chemical, THC, produced by glandular trichomes on female flowers, but low-THC producers (hemp) are cultivated for fibers. Flowering time affects…

The concept of pollination syndromes posits that floral diversity arises from shifts among pollinator groups, yet their predictive accuracy for pollinator identification is debated. Kopper et al. leveraged machine learning, utilizing 44 floral traits from 252 species with known pollinator interactions,…

Review: The plant immune system: From discovery to deployment A review of the past 50 years of plant immunity by Jones, Staskawicz, and Dangl? Yes please! I particularly enjoy historical perspectives of a discipline, as they frame conceptual breakthroughs with the benefit of hindsight. As the article…
