homothallic वाक्य

They may germinate to form hyphae or a sporangium . " Mucor " includes both homothallic ( self-compatible ) and heterothallic species.
Among those " Aspergillus " species for which a sexual cycle has been observed, the majority in nature are homothallic ( self-fertilizing ).
Their coenocytic; sporulation occurs by production of forcibly discharged dispersive or infective conidia; and their zygospores ( which also function as resting spores ) are homothallic.
Heterothallic mating has been best studied in " Dictyostelium discoideum " and homothallic mating has been best studied in " Dictyostelium mucoroides " ( strain DM7 ).
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.

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.
The " Closterium peracerosum-strigosum-littorale ( C . psl ) " complex is a homothallic ), whereas others form zygospores between different clones of cells ( heterothallic ).
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 ).
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.
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.
