Best of 2016: Top Topics in Plant Physiology jounal

We’ve highlighted some of the Plant Physiology papers that were widely shared, liked, blogged, retweeted and otherwise garnered high-levels of attention this year. Perhaps you can use some of that holiday-season quiet time to catch up on those you missed. The breakaway attention-getter from Plant…

Improving Rubisco

/
Rubisco (Ribulose-1,5-bisphosphate carboxylase / oxygenase) is the enzyme responsible for fixing almost all inorganic carbon into organic form, but it is not optimized for current conditions. As temperature and CO2 levels increase, there is an opportunity to increase photosynthetic efficiency by engineering…

Review: Biogeochemical effects of early life on land

/
Earth colonization by life happened billions of years ago. Weathering of soils by microbial mats leave a characteristic signal that can be used to shed light on the mechanisms involved in colonization. In this review, Lenton and Daines discuss the growing mass of evidence that points to the biogeochemical…

Transcript, protein and metabolite dynamics in CAM-plant Agave ($)

/
Crassulacean acid metabolism (CAM) is a specialized form of photosynthesis that greatly increases water-use efficiency by taking up CO2 through stomata that are open at night (when evapotranspiration is low). Engineering plants that can switch to CAM during periods of drought is a key goal towards…

Molecular basis for plant growth responses in shade and under competition for light ($)

/
The wavelenghts of light perceived by a plant are information-rich, and plants integrate information from photoreceptors tuned to different wavelenghts to optimize their growth and development. Because plants absorb red light but not far-red light, a low ratio of red to far-red light indicates vegetative…

Commentary: Chemical nature of the root-shoot signals

/
Unravelling the mechanism and signals originating from roots and able to contribute to stomatal control has been the subject of research for decades. In this commentary, Tardieu summarizes and discusses many studies and models on root-shoot signals, including work in the same issue by Visentin et…

Field of Genes: Uncovering EGRINs (Environmental Gene Regulatory Influence Networks) in Rice That Function during High-Temperature and Drought Stress

/
IN BRIEF by Jennifer Lockhart jlockhart@aspb.org Heat and drought stress greatly restrict crop productivity, but most of what we know about a plant’s response to these stresses comes from controlled laboratory studies. This factor, along with the complex nature of these responses, has hampered efforts…
