Whole plant chamber to examine sensitivity of cereal gas exchange to changes in evaporative demand (Plant Methods)
Plant Science Research WeeklyStomata represent the entry point into the leaf for CO2 that will be fixed by rubisco in photosynthesis and the exit point of water as it is lost to the atmosphere. As such, they are subject to tight regulation in response to the environment so that water loss is minimised and a supply of CO2 is…
Rate of photosynthetic acclimation to fluctuating light varies widely among genotypes of wheat (bioRxiv)
Plant Science Research WeeklyThe speed at which photosynthesis is induced during shade-sun transitions, such as sun-flecks, contributes towards determining crop yield. The speed of induction can be limited by the dynamics of stomatal and mesophyll conductance, deactivation rates of photoprotective mechanisms, the acclimation rate…
Expert View: The nitrogen cost of photosynthesis (J Exp Bot)
Plant Science Research WeeklyModern crop production is intimately linked to the availability of nitrogen. Photosynthetic proteins (including rubisco) account for most of the nitrogen in leaves, a significant amount of which is removed during harvesting and must be replenished primarily through the application of synthetic nitrogen…
Review: Discovery of the canonical Calvin–Benson cycle (Photosynth Res)
Plant Science Research WeeklyIt has been over seventy years since Melvin Calvin and Andrew Benson first started on their journey to discovering the Calvin-Benson cycle – the series of biochemical reactions in which the Sun’s energy is converted to chemical energy stored inside the cells of plants, cyanobacteria and algae. …

Biologists, ecologists, foresters and naturalist increasingly argue that plants speak and the human can learn…
Autophagy and Chloroplast Quality Control: Fatty Acid Synthesis Counts
Plant Physiology, Plant Physiology: News and ViewsPlants devote more than 70% of their available nitrogen to maintaining chloroplast function (Makino and Osmond, 1991). During senescence or under stress conditions, chloroplasts are degraded and their constituent components are recycled. Chloroplasts can be degraded through at least three pathways: (1)…
