Annotated Information
Gene Symbol
- Os11g0592000 <=> OsPR4c,PR4c
Function
- PR4 proteins constitute a pathogenesis-related (PR) protein family with a conserved BARWIN domain.
- The rice PR4 genes are also involved in abiotic stress responses and tolerance in addition to their responsiveness to pathogen attacks.
Phenotypic analysis
- Transgenic rice with overexpression of OsPR4a showed enhanced tolerance to drought at both seedling and reproductive stages..
Expression
- OsPR4 genes showed diverse temporal–spatial expression patterns, and their expressions are responsive to Magnaporthe grisea infection. Interestingly, the OsPR4 genes are also responsive to abiotic stresses.
- Their expression levels were strongly induced by at least one of the stress treatments including drought, salt, cold, wounding, heat shock, and ultraviolet.
- The transcript levels of OsPR4 genes were also induced by some phytohormones such as abscisic acid and jasmonic acid.
Evolution
- The PR4 genes are located in tandem on chromosome 11 and constitute a gene cluster with high sequence similarity to each other.
- The OsPR4 proteins have high sequence similarity to reported PR4 proteins from monocotyledonous species and are predicted to be class II PR4 proteins.
- Distinct diversification of plant PR4 proteins exists between monocotyledonous and dicotyledonous plants.
