male barren-1

locus: mb-1

locus_name: male barren-1

organism_type: B

chromosome_number: VII

chromosome_side:

link_group: VII

cultural_requirements: VII. Linked to nic-3 and wc-1 (23%) (1100, PB).Perithecial development is blocked when the mb-1 mutant is used as the male parent to fertilize an mb+ female: many perithecia are produced, mostly small, brown, without beaks or ascospores; a few perithecia mature and produce ascospores (1100). Perithecia are reported to be normal and fertile when the mb-1 mutant is the female parent fertilized by an mb+ strain (1128); however, some abnormality as the female has been observed cytologically after pachytene (N.B. Raju, personal communication). Homozygous barren (PB). Recessive in heterokaryons, complementing mb-2and mb-3(1101). One occurrence: allele 8455.
