Os07g0129200

The rice Os07g0129200 was reported as PR1A in 2000 by researchers from Japan.

Annotated Information

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
Activation of OsPR1a gene is an important part of the defence/stress response(s) in rice.

The OsPR1a gene was found to be cut-inducible, whereas the phytohormones JA, salicylic acid (SA), 3-indoleacetic acid, gibberellin, and ethylene (using ethylene generator ethephon, ET) enhanced accumulation of OsPR1a transcript, as well as the protein phosphatase inhibitors cantharidin (CN) and endothall (EN).
Induced expression of OsPR1a gene by JA, CN or EN, and ET was light/dark- and dose-dependent and was almost completely inhibited by cycloheximide.
Dark downregulated CN-, EN-, and ET-induced OsPR1a gene expression, whereas it was further enhanced with JA. SA and abscisic acid blocked JA-induced OsPR1a transcript.
