Lieve DeceuninckDear Forum
Bonjour Forum

Literature request : Mycotaxon 81: 243-249 (2002) A natural mutant of Ascobolus michaudii


In 2011 on chambre cultured dung of rabbit an Ascobolus was cultivated.  All asci that contains ripe spores shows four ripe and four immature spores.
This anisospory by the genus Ascobolus also is described by Van Brummelen (Persoonia 1967) p 45 en 46 but I'm looking forward some extra literature .


Does anybody can send me the article below? Thanks in advance. Lieve Deceuninck.


Diana A. & María E. Ranalli. A natural mutant of Ascobolus michaudii (Ascomycotina, Pezizales).
Mycotaxon 81: 243-249. 2002.


ABSTRACT: Wild strains of Ascobolus michaudii produce 8-spored asci and uninucleate ascospores with thick anastomosing lines in the exosporium.
A natural mutant in heterozygous condition with ascospores showing a thin verrucosely ornated exosporium was isolated.
The exosporium types segregated in a ratio of 4:4 in the ascus, suggesting a typical Mendelian outcome controlled by a single allele pair.
Six expected patterns were observed. Since mutant ascospores germinate normally, mutant homozygous cultures were obtained.
Cultural studies using various media show no interference with the segregation pattern.
