Gene Details:

• MSU gene ID: LOC_Os05g32600
• RAPdb gene ID: Os05g0392300
• Gene Symbol: R2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• We have analyzed the expression of four rice (Oryza sativa) CDK genes, cdc2Os1, cdc2Os2, cdc2Os3, and R2, by in situ hybridization of sections of root apices.
• Transcripts of cdc2Os1, cdc2Os2, and R2 were detected uniformly in the dividing region of the root apex.
• When R2 was overexpressed in a CAK-deficient mutant of budding yeast, it suppressed the temperature sensitivity of the mutation.
• Increasing R2 abundance through a transgenic approach accelerated S-phase progression and overall growth rate in suspension cells.
• In planta, the CTD kinase activity of R2 was induced by a growth-promoting signal.
