Programmed cell death in plant disease: the purpose and promise of cellular suicide.

The interaction of pathogens with plants leads to a disruption in cellular homeostasis, often leading to cell death, in both compatible and incompatible relationships. The mechanistic basis of this cellular disruption and consequent death is complex and poorly characterized, but it is established that host responses to pathogens are dependent on gene expression, involve signal transduction, and...

The promise and limitations of DNA microarray analysis: comment on the editorial by Firestein and Pisetsky.
