Location of Wrp1
--M. G. Neuffer

The dominant wrinkled plant mutant (Wrp1) discovered by Bockholt and Smith (MNL63:56) was tested for location to chromosome with wx marked translocations. Linkages were found on three translocations involving chromosome 2 but not for any of the others.
The data from chromosome 2 are listed below:

From these data it appears likely that Wrp1 is located on the long arm of chromosome 2 between wx1 T2-9b and T2-9d breakpoints.
