They may germinate to form hyphae or a sporangium . " Mucor " includes both homothallic ( self-compatible ) and heterothallic species.
12.
Among those " Aspergillus " species for which a sexual cycle has been observed, the majority in nature are homothallic ( self-fertilizing ).
13.
Their coenocytic; sporulation occurs by production of forcibly discharged dispersive or infective conidia; and their zygospores ( which also function as resting spores ) are homothallic.
14.
Heterothallic mating has been best studied in " Dictyostelium discoideum " and homothallic mating has been best studied in " Dictyostelium mucoroides " ( strain DM7 ).
15.
When starved for their bacterial food supply and exposed to dark, moist conditions, heterothallic or homothallic strains can undergo sexual development that results in the formation of a diploid zygote.
16.
However, homothallic meiosis may be maintained in " Closterium peracerosum " as an adaptation for surviving under stressful conditions such as growth in nitrogen depleted media at low cell density.
17.
The " Closterium peracerosum-strigosum-littorale ( C . psl ) " complex is a homothallic ), whereas others form zygospores between different clones of cells ( heterothallic ).
18.
Among the 250 known species of aspergilli, about 36 % have an identified sexual state Among those Aspergillus species that exhibit a sexual cycle the overwhelming majority in nature are homothallic ( self-fertilizing ).
19.
These are outcrossing ( in heterothallic fungi ) in which two different individuals contribute nuclei to form a zygote, and self-fertilization or selfing ( in homothallic fungi ) in which both nuclei are derived from the same individual.
20.
Members of the Mycetozoa group are able to undergo sexual reproduction either by homothallic mating An analysis of meiosis-related genes in the " Dictyostelium discoideum " genome revealed that 36 of the 44 genes tested were present in the genome.
