Tartalmi leírás:
One of the most typical and best
studied type of plant resistance is the hypersensitive response (HR), a form of
localized programmed cell death associated with restriction or even killing of
pathogens that often leads to macroscopically visible localized tissue
necrosis. It is generally assumed that cell death and resistance within the HR
are physiologically and genetically linked. However, there has been
considerable speculation about whether cell death is an absolute requirement
for resistance conditioned by the HR. This review discusses the relation of
cell death and resistance in the HR, in particular, the importance of cell
death in this process. We intend to focus on the increasing amount of research
evidence showing that in several plant-pathogen
interactions, the two main components of the HR-resistance and cell death-can be physiologically, genetically and temporally
uncoupled. In other words, HR should be considered as a combination of
resistance and cell death responses, where cell death may be dispensable for
the plant resistance response. The varying contribution of these two components
(i.e. cell death and resistance) generates an array of defense strategies -
ranging from extreme resistance to“systemic
HR”- applied by resistant host plants in the battle against
pathogen infections.
