Previous Article Variant PRC1 Complex-Dependent H2A Ubiquitylation Drives PRC2 Recruitment and Polycomb Domain Formation. Next Article A Hierarchical Map of Regulatory Genetic Interactions in Membrane Trafficking When a pathogen is capable of causing disease on a particular host species, two outcomes are possible: A compatible response is an interaction that results in disease, while an incompatible response is an interaction that results in little or no disease at all. Although a particular plant species may be a susceptible host for a particular pathogen, some individuals may harbor genes that help. Similarly, host defence reactions can range from non-specific stress-induced responses to very specific reactions based on the presence of individual genes in both the host and pathogen; the gene-for-gene interaction as described by Flor (1971). Climate-change factors also may differentially effect these interactions, as inducement of general. The following evidence suggests that OsPAD4 may not be the functional ortholog of AtPAD4 in host-pathogen interactions, however, considering that OsPAD4 is a plasma membrane protein and that AtPAD4 is a cytoplasmic and nuclear protein.
