--Yong-Bao Pan and Peter A. Peterson
Our genetic tests have indicated that the activated Uq element
at the mn-866248U mutant locus (MNL 61:6; 62:5-6) is not the standard
type of Uq. This conclusion is derived from the following observations:
1) The mn Uq, whether in the original mutant or in an a sh2/a
sh2 construct, is capable of transactivating the standard a-ruq
reporter allele resulting in a miniature spotted phenotype which distinctly
differs from the spotting type produced by the standard Uq/a-ruq
interaction (data not shown); 2) it does not transactivate a Uq-responsive
c-ruq reporter allele (data not shown). This is in contrast to most
standard tests with Uq elements, where a-ruq and c-ruq
always show corresponding responses.
