Abstract
Powdery mildew (Erysiphe graminis) reduces the UK barley crop by some 10%. Its vigour is a function of the host nutrient and water status. Moreover, its localised site of contact with the host makes it a useful tool for studying barley leaf solute and water relations at the cell level. The interactions of these relations between barley epidermal cells and the parasite will be analysed with single-cell microanalysis and pressure-probe techniques. Two objectives will be sought. i) The localisation of key factors of the disease triangle between host/parasite and non-biotic environment - eg. nutrient (K+, Ca2+. phosphate, NO3-) and water status. ii) Mapping the pathways of solute and water flow within the healthy leaf and the influence of the parasite upon these.
