The protein complex ARP2/3 is responsible for nucleating actin, and its loss results in multiple defects in young seedlings of Arabidopsis thaliana. Sahi et al. show that plants lacking the ARP2/3 complex have defects...
Pollen tubes are rapidly growing, photosynthetically inactive cells that need high rates of energy to support growth. Energy can derive from internal and external storage sources. The lack of carbon sources can cause...
What is it that makes a plant get up and stay up? A new review looks at the creation of secondary cell walls. These microscopic features are the key to understanding the architecture of the plants we see around us.
Arguably, one of the best known ‘structure-function’ relationships in plant biology is the role played by cellulose microfibrils within the walls of the guard cells in stomatal opening. Stomata* are the controllable...
Much of plant biomass is in roots but we know much less about root properties that affect decomposition rates than we do about above-ground tissues. Aulen and Shipley measure decomposition rates of 17 species of trees...
