The Amazonian forest is an enormous and crucial ecosystem that encompasses a huge proportion of Earth’s biodiversity and stored carbon. By overlaying maps showing forest inventory plots and sites of ancient human impact, McMichael et al. observe that the inventoried plots from which we draw conclusions…

The Amazon rainforest stores 30% of land-based ecosystem carbon. How are carbon stores affected by selective tree removal and subsequent regrowth? Stored carbon continues to be lost for several years after logging due to damage-associated mortality of surviving trees. Piponoit et al. use data from more…

Disease-causing organisms attack as a population of diverse individuals. Is it possible to reduce the virulence of this population by introducing less-virulent individuals?  Some studies have shown such an effect; as an example, application of low-virulence strains of Aspergillus flavus can protect…

Two papers in Current Biology examine the genetics behind plant-pollinator interactions , focusing on genes controlling floral scent. Amrad et al. 10.1016/j.cub.2016.10.023 explore differences between bee, hawkmoth and hummingbird pollinated species of Petunia. They identify changes in expression in…

The autophagosome, a cellular compartment involved in the turnover of macromolecules, contributes to nutrient homeostasis, stress resilience and defense. Although several proteins have been identified as contributing to autophagosome formation and function, the precise origins of the autophagosome have…

Plants perceive microbial pathogens though cell-surface receptors that recognize conserved microbial patterns such as flagellin. Previous studies have identified the WRKY family of transcription factors as contributors to Microbial-Associated Molecular Pattern (MAMP)-Triggered Immunity (MTI). Birkenbihl…

When a plant species is introduced to a new region, it brings with it “hitchhikers” – other associated organisms. Sometimes, these hitchhikers negatively impact the environment into which they are introduced, for example by facilitating the host’s invasiveness, or through direct detrimental effects…

Orphan legumes, which include cowpea (Vigna unguiculata), Bambara groundnut (V. subterranea), grass pea (Lathyrus sativus) and marama bean (Tylosema esculentum), are important food sources for many farmers, but have largely been ignored by breeders and industry. Cullis and Kunert argue that some of these…
