The sweetpotato whitefly, Bemisia tabaci, are devastating crop pests that lower yields and transmit viruses. They feed off more than 600 species, most of which produce toxic phenolic glycosides. Xia et al. investigated how the whiteflies manage to avoid the effects of the toxin. They found convincing evidence that this group of insects, but not […]
Update: Lateral root formation and nutrients: nitrogen in the spotlight We marvel at the ability of starfish to regenerate an arm, or a lizard a new tail, but even more impressive than these feats is the ability of a plant root system to create lateral roots when and where they are needed. This root system […]
Roots and shoots exist in different environments and have different functions, but each depends on the actions of the other. In recent years, many factors have been identified that move from root to shoot or vice versa to integrate their actions; these include hormones, small RNAs, peptides, and transcription factors. This fascinating review article takes […]
The effects of light on plant growth are incredibly complex and depend on where it is perceived, light quantity, light quality (wavelength), and when within the circadian cycle it is perceived. Romanowski et al. examined the effect of late-day far-red light perception in Arabidopsis leaves. This treatment is known to induce shade-avoidance syndrome, which is […]
Genetic studies have provided us with countless examples of regulatory switches that transduce a signal into a response. Mutant analysis is usually sufficient to identify these controlling elements, but often in an all-or-nothing way. Here, Ghusinga et al. have taken a theoretical kinetic approach to examine how three types of switch architectures affect the properties […]
Review: Microbiota-root-shoot-environment axis and stress tolerance in plants ($) Roots and shoots exist in different environments and have different functions, but each depends on the actions of the other. In recent years, many factors have been identified that move from root to shoot or vice versa to integrate their actions; these include hormones, small RNAs, […]

Please help us envision and achieve a better Society Take a moment to imagine what the ideal professional society would be. How would decisions be made, opportunities allocated, scientists supported? Are we there yet? We hope we’re close, but we know that the best ASPB will be the one that continues to grow with our […]
The root system has three key functions: support/anchoring, uptake of water, and uptake of nutrients. Many questions remain about how roots integrate all of these functions into the architecture of a single system. Here, Bardhan et al. explore whether modifying the nutrient environment (hence root’s foraging responses) can enhance root water uptake capabilities. The authors […]
