Nonhost resistance and nonspecific plant defenses

Abstract

In the past year, most of the advances in our understanding of nonhost resistance to plant pathogens have been incremental. Highlights include the discovery of a general bacterial elicitor of plant defenses, the description of more similarities between the hypersensitive response and animal programmed cell death, and a growing appreciation of the cell wall as the site of initiation and expression of nonhost resistance towards fungi.
