    Waring out the carbon: is net primary productivity proportional to gross primary productivity?

    Gross primary productivity represents the total carbon fixed through photosynthesis in an ecosystem. Since plants also breakdown sugars produced through photosynthesis, releasing carbon and energy for metabolism, plant respiration uses up a substantial portion of gross primary production. Net primary productivity is the difference between these two processes and represents the carbon available to the […] More

    All good things come to an end…

    This Cuttings collection is the last that will appear in the Annals of Botany journal. Since the column was launched on an unsuspecting world in January 2010 it’s been my unalloyed pleasure and joy to share with you my thoughts (admittedly, not always fully-formed or sensible…) on many topics with a loosely plant-based theme. If […] More

    To drink, or not to drink – do trees coordinate their water supply with environmental conditions?

    Predicting future responses of trees to drought is notoriously difficult, requiring consideration of many factors, including temperature, soil type, and how trees regulate their water usage. Water regulation in trees can be described along a spectrum from isohydric (maintaining a constant leaf water status under a changing water supply) to anisohydric (allowing leaf water status […] More

    Non-Specific Phospholipase C2 (NPC2) in plant immune responses in Arabidopsis

    The non-specific phospholipases C (NPC) are recently discovered new subclass of plant phospholipases. Most of them have not yet been characterised thoroughly. Krčková et al. prepare and purify Arabidopsis thaliana NPC2 in a heterologous system, and experimentally proved its phospholipase activity in vitro. Using lines overexpressing NPC2: GFP. They determine its endomembrane (preferentially Golgi apparatus) […] More

    The Return of the Rainbow Rose

    One of our most popular posts is Roses are red – but they don’t need to be, if you know how to use food dyes and Fibonacci. In it, Anne Osterrieder explains how to make your own rainbow rose. Not everyone is convinced the method works. As the video above from Threadbanger shows, it’s really […] More
