Abstract

A long-standing question in both agriculture and nature is why plants are resistant to most species among the vast community of bio-antagonists but not to all of them. One answer may be that strong resistance of a plant to one disease often incurs greater susceptibility to other diseases, particularly those with different trophic lifestyles. Another is that traits that maximise a plant’s ability to escape infection may not be optimal for growth and development. I will illustrate these points with examples from wheat and barley and I will discuss ways in which agriculture could draw on concepts from natural ecosystems to achieve durable, broad-spectrum disease resistance.
