When is a genome-edited plant a GMO (and subject to GMO-restrictions)? Wolter and Puchta summarize two important papers that show that CRISPR/Cas genome editing can be achieved in wheat and rice without the introduction of foreign DNA (making these plants “not GMO”), by delivering complexes of enzyme…

Evolution starts with molecular variation and phenotypic diversity, upon which selection acts. Flood and Hancock review the approaches used to detect adaptive evolution. The top down approach starts with the phenotype and works to identify its genomic basis; examples are quantitative trait locus (QTL)…

The idea that the microbes on and within an organism (the microbiota) influence an organism in positive, neutral and negative ways has been a hot topic in popular science, especially the role of the gut microbiota in human health and nutrition. Plants are similarly influenced by their microbiota, as…

The formation of a maize kernel requires growth coordination between embryo, endosperm, and surrounding maternal tissues. Key molecular actors in this coordination are hormones, sugars, peptides and transcription factors. Doll et al. review recent advances in our understanding of maize kernel development,…

As photosynthetic autotrophs, plants have the potential to convert sunlight into a vast array of useful products: to act as little green metabolic factories. Of course, they already provide us with everything from carbohydrates and vitamins to stimulants and medicinal compounds, but with a few small…

Did you know that bananas are: one of the top ten world food crops, the world’s most popular fruit, eaten in nearly every country, and an important food security crop in regions where they are grown? Did you also know that most bananas are triploid and usually sterile, making conventional breeding…

Activity-based protein profiling is a proteomics approach that involves covalently labeling reporter tags to subsets of proteins based on their active sites. Morimoto and van der Hoorn define different types of probes and the types of proteins that they bind to. Activity profiling can reveal different…

The ability of trees to offset carbon emissions has been questioned after a Western Sydney University study found common Australian trees are unable to store as much carbon as previously thought. Published in the Nature Climate Change journal, the research found that Australia's iconic Eucalyptus…
