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 […]
It’s like the plot of every spy movie you’ve ever seen. If you could infiltrate your opponent’s headquarters what would you target to disable your enemy? This is the question addressed in new work by Petre et al. More than ten years ago, a family of small proteins was identified, the RXLR proteins (named for […]
Two very exciting papers have come out this week in Nature that address a long-standing question about the relative contributions of two different plant immunity pathways. PTI (pathogen-triggered immunity) recognizes conserved pathogen signatures at the plant cell surface; a model system for PTI is the interaction between the bacteria flagellin protein (or the peptide flg22) […]
Review: Can smart nutrient applications optimize the plant’s hidden half to improve drought resistance? 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 […]
Light comes largely from above, and plants have evolved strategies to efficiently capture this light even when competing with other potentially shading plants. However, at a field-level, such competition may (and does) prevent plants from collectively maximizing light use efficiency, hence yield. In this comprehensive review, Slatterly and Ott provide an overview of years of […]
This is an engrossing paper. The authors start off with a simple mutant screen for abnormal root growth in rice seedlings, through which they identified three “long root” mutant alleles of a rice mutant in a gene encoding a histidine kinase, HK1. Careful analysis showed that the mutant roots fail to circumnutate (a growth pattern […]
