Are you planning to be in San Diego in January for the Plant and Animal Genome (PAG) meeting? The American Society of Plant Biologists (ASPB) is exhibiting there and we would love to meet you. Come by and see us at booth 634. Learn more about our journals, The Plant Cell, Plant Physiology, and Plant […]
Since most of us will have a few days off this coming week as we welcome in 2020, I’d like to highlight some of the engrossing reviews in this special issue of Current Opinion in Biotechnology, edited by Ralf Reski, Gary Foster & Ed Rybicki. Several of the articles focus on Molecular Pharming, or the […]
Much of our understanding of abiotic stress response comes from studies on short-lived annual plants, for good reasons: they are small and easy to study, their short-generation time makes them amenable to genetic studies, and most of our food comes from annual plants. Trees are more difficult to study, but no less important in their […]
The first line of defense is detection. Plants have numerous cell-surface receptor proteins (Pattern Recognition Receptors, PRRs) that recognize potentially harmful pathogens as well as endogenous molecules that suggest damage, known as Damage Associated Molecular Patterns or DAMPS and phytocytokines (not to be confused with cytokinins!). If you’re not working in this area, it can […]
Legumes benefit from mutualistic symbioses with Rhizobia bacteria, which are induced to fix nitrogen when inside of the nodules produced by the plant. Cereals also associate with Rhizobia, but without nodules they don’t fix nitrogen. Ryu et al. set out to engineer inducible nitrogenase activity in free-living Rhizobia and other bacteria that associate with cereals. […]
Biosensors have provided abundant information about the distribution of target enzymes, for example auxin, revealing much about their roles in plant physiology and development. Ethylene is a tiny (C2H4) gaseous hormone that hasn’t been very amenable to the development of biosensors. Here, Vong et al. describe the development of an albumin-based artificial metalloenzyme (ArM) that […]
Numerous genes have been identified that modify shoot architecture, which has allowed breeding of varieties for specific purposes and environments. Here, Kwon et al. describe how they have used gene editing to modify several of these genes to produce tomatoes and groundcherries that are compact and rapid cycling, so are optimized for restricted growth environments […]

Reading this review by Diaz et al. feels a bit like reading a bad report card. Although we know we’re failing in our role as Earth’s stewards, we don’t always want to be reminded of this. But, in this case we need to read and act on the suggestions for improvement. The authors review the […]
