(15) Dissection of asci from these clones yielded some single-spore clones which showed mating reactions with one or the other or both haploid tester strains, and further selection produced strains which on sporulation and dissection yielded single-spore clones which were apparently bisexual and sporulated freely.
(16) The SMO genetic locus in strains of the fungus Magnaporthe grisea that infect weeping lovegrass, directs the formation of correct cell shapes in asexual spores, infection structures, and asci.

(20) A physical map of the chromosome was constructed for NotI, AscI, and SrfI by using single and double digests, or partial NotI digests obtained at random or by cross-protection of NotI sites by FnuDII methylase, and linking clones.
