Interpretive Summary: This manuscript reviews our understanding of an important plant defense response called the hypersensitive defense response or HR. HR is a rapid, localized cell death at the point of pathogen infection. It is often very effective in conferring disease resistance but it has potentially severe costs if activated inappropriately. The review discusses the consequences of HR and how it is controlled. Technical Abstract: The plant hypersensitive defense response is found in all higher plants and is characterized by a rapid cell death at the point of pathogen ingress. It is usually associated with pathogen resistance, though, in specific situations, it may have other consequences such as pathogen susceptibility, growth retardation and, over evolutionary timescales, speciation. Due to the potentially severe costs of inappropriate activation, plants employ multiple mechanisms to suppress inappropriate activation of HR and to constrain it after activation. The ubiquity of this response among higher plants despite its costs suggests that it is an extremely effective component of the plant immune system. |
