We routinely isolated RNA both total and polysomal from tissue that was
quick frozen in liquid nitrogen. Tissue was then stored at -70 for various
amounts of time. Some as long as a year. We never seemed to have any
trouble with degradation of the RNA. The tissue was from roots and
nodules. I suppect that the cryoquick and storage at -70 will be good.
