Abstract

Germlings of E. graminis develop abnormal infection structures on many artificial and some potential host plant surfaces. The role of the fungal primary germ tube in recognising the plant surface and the subsequent involvement of intracellular signalling for further germling development will be explored. The potential to interfere with the recognition and response process, and thus to convey disadvantage to the pathogen, will be assessed by various means including studies of artificial surfaces, and using eceriferum barley mutants and non-host grass species. The effects of external factors (e.g. light) on the maturation of appressoria will be explored. Many fungi produce extracellular material during attack. The possibility that E. graminis does so as part of the recognition/response sequence will be investigated. The role of host `wall' degrading enzymes (e.g. cutinase, cellulases) during germling development will be examined.
