At the moment I'm setting up some repeat mutation experiments with Cladosporium and then I'll junk the organism. I am now going ahead with some ideas on nuclear and possibly somatic recombination in [ . . . ]. We have a Canadian, Clayton Person who is going to join Johnson at Winnipeg this fall, working in our cytology lab. He finds large nuclei which have two nucleoli in sectiared stem [ . . . ] material. They occur rarely but look like diploid nuclei.
