Subject: Re: FlyBase Query (UB883)
Dear Chihiro,
yes UB883 is the rst-allele we mention in later papers.
We isolated the P-element induced allele UB883 and an X-ray induced inversion,
called 1R34 of the irreC-rst locus (no mostly called rst locus).
UB883 is now the rst allele irreC1
1R34 is now the rst allele irreC2
Best regards, Karl
