Annotated Information
Function
Pathogenesis-related proteins(PR) have production/accumulation represents an essential component of the active plant defence repertoire.And they have been used as markers of plant defense responses.The dicot PR1 are recognized as reliable marker genes in defence/stress responses[1].
They are defined as plant proteins that are induced specifically in pathological or related situations.
Activation of OsPR1 genes is an important part of the defence/stress response(s) in rice.
Expression
The responses of individual genes to salicylic acid, jasmonic acid, and ethylene induced defense signaling pathways in rice are likely to be different from those in dicot plants. Transcript levels in healthy leaves, roots, and flowers varied according to each gene[2].
OsPR1a and OsPR1b genes were primarily characterized against jasmonic acid, ethylene and protein phosphatase 2A inhibitors. The dicot PR1 are recognized as reliable marker genes in defence/stress responses.SA, ABA and H2O2 up-regulate the expression of OsPR1a and OsPR1b genes(fig1)
