Larson, David L. Kelly, and A. Thomas Weber Department of Biology, University of Nebraska at Omaha, Omaha, NE 68182-0040 Trans. Am. Microscop. Soc., in press ABSTRACT A mutant of Dictyostelium mucoroides was isolated following treatment with nitrosoguanidine. This mutant produced morphologically aberrant sorocarps and macrocysts. The absence of a sorophore sheath and primary macrocyst wall was confirmed by light microscopy, fluorescence microscopy of both calcofluor and fluorescein- conjugated concanavalin A stained specimens, and by scanning electron microscopy. Mutant sorocarps formed without a sorophore sheath were normally proportioned, but had weak, curly, cellular stalks. Macrocysts without the primary wall did not cluster as did the wildtype macrocysts and often were irregular in shape rather than spherical. These results suggest a common origin for the pseudoplasmodial and sorophore sheath and the primary macrocyst wall in the cellular slime molds. ---------------------------------------------------------------------- Registration Form for 1994 Dictyostelium meeting in San Diego A copy of the registration form for the !994 International Dictyostelium Conference follows. Make copies for friends or anyone in the lab that may not be on either of the two lists. Others that are not as well connected should see the Cell add and thus will contact us directly for the form. We are trying to save at least the initial mailing costs since this helps reduce the costs a bit. As stated below, the mechanics of the meeting are being done by the UCSD Conference Center. Please note the dates for receipt of registration forms, prepayment, and for abstracts. We are looking forward to a great meeting and hope that as many people as possible will attend.

The meeting is being coordinated by the UCSD Conference Center and all fees and late charges are set by the Center and not by the organizers.
