(1) Although growth of two yeast strains characterized by consistent production of two diploid spores per ascus was inhibited in complex presporulation media containing amitrole, a fraction of the cells produced were able to form asci with more than two spores after transfer to acetate sporulation medium.

(5) The proportion of spindle overlap and recombinational asci within the group did not change as shown by ascus dissection.
(6) Diploids carrying these suppressors upon sporulation yield asci with only two live spores, both lacking the suppressor.
(7) In the three spored asci, which occur rarely, only one nucleus is surrounded by a spore wall after meiosis I; the other nucleus undergoes meosis II before the onset of spore wall formation.
(8) The isolate resembles M. cannonballus in the type of ostiole developed but M. eutypoides in having mainly two-spored asci.

(10) In cdc1-7, cdc5-120, cdc17-L16 and cdc18-46 no abnormalities were observed; cdc10-129, cdc20-M10, cdc21-M6B, cdc23-M36 and cdc24-M38 formed four-spored asci but with a low efficiency; cdc22-M45 was completely defective in meiosis, but could conjugate and formed zygotes with a single nucleus.
(11) Two of the sg-mutants (sg 2 and sg3) produced abundant cleistothecia with asci and ascospores when back crossed to parents of opposite mating type.
(12) Yeast vegetative cells were stained reddish purple, but zygotic asci were bluish.
(13) The increase in spore numbers per ascus is attributed either to the induction by amitrole in growth medium of cells with more than one nucleus or to the restoration of normal meioses in the multispored asci.
(14) Summation of results for 10 individually sized AscI fragments estimated the genome length to be 1,861 kb for the four strains (H, PAC1.0, PO2, and JBL1350) with identical fingerprints.
(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.
(17) The Eight-spore gene E, which shows variable penetrance, was used to obtain N. tetrasperma asci in which two to eight spores are small and homokaryotic.
(18) In one case of suppression, the asci also show segregation at the plasmid level.
(19) Each plasmid segregated from an intact unpaired copy of chromosome I at the first meiotic division in a significant majority (63-93%) of the asci examined.
(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.
