Plants experience stress in response to changes in the environment including drought, heat, pests and diseases (see my blog post about plant stresses). When plants experience extreme stress it can be relatively easy to detect. Wilting can indicate drought and heat stress, yellowing of leaves can suggest nutrient deficiency, whilst browning of leaves can indicate … More Eye in the sky for crop stress
Working at the James Hutton Institute means there is a massive scope of research all around me! From hydrology just down the corridor, analytical sciences downstairs and social science two floors down, the range of expertise in one building is amazing (there’s even more at the Dundee site!). Once a year this expertise is brought together … More Hutton Symposium 2018
Unlike animals, plants run away from danger. The environment often puts multiple stresses on a plant at once, such as heat and drought stress during the summer or a pest and disease attacking at the same time (1). Plants therefore need to detect and respond to the environment as it changes around them. However, responses … More Ahhhhh stressed plants!
Trace concentrations of metals such as nickel, cadmium and selenium are present in most soils. Plants require very low concentrations of many metals as micronutrients, but high concentrations can be toxic. High metal concentrations can occur naturally in some soils due to underlying geology or can occur through human activities such as mining, pesticide application and … More Poison or Protection?
