We have in fact been contemplating such an approach for some time to try and get at the molecular basis of our radiation- induced tumors which do not regenerate plants and defy conventional genetic analysis. However, we have so far been unable to identify suitably informative probe(s). i.e. ones present in high copy number (1000+) and interspersed throughout the genome, as suggested by the Brilliant article. We have one tumor line which repeatedly throws off fast-growing variants which are shooty and have very high cytokinin levels. Comparison of these variants with each other and with the parent line (as well as with normal plant and with other tumors) could be very informative. I would be very pleased to receive suggestions os to possible probes whwich might be suitable for this. Many thanks, Chris Town.
