internal standard for RT-PCR

[daemon at net.bio.net]

Hi everybody,
Does anybody know a good candidate gene to serve as internal standard in
RT PCR on Arabidopsis RNA. It has to fulfill these two requirements:
constitutively expressed in all organs and at every stage of
development, and very low expression (my gene of interest is itself low
expressed and I want to co-amplify the standard and the target). Any
advice is welcome.
Thank you very much.
