Gene Details:

• MSU gene ID: LOC_Os03g04310
• RAPdb gene ID: Os03g0135700
• Gene Symbol: RAI1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• RAI1 encodes a putative basic helix-loop-helix transcription factor.
• In this study, we have identified RAI1 as the first transcription factor acting downstream of OsRac1.
• The PAL1 and OsWRKY19 genes were also up-regulated by sphingolipid and chitin elicitors, and the RAI1 activation-tagged plants had increased resistance to a rice blast fungus.
• These results indicated that RAI1 is involved in defense responses in rice.
• In addition, we observed changes in RAI1 levels during blast infection, which led to identification of OsRPT2a, a subunit of the 19S regulatory particle of the 26S proteasome.
