homothallic การใช้

• Unlike its close relatives that are heterothallic, H . moniliformis exhibits a homothallic sexual strategy.
• Homothallic " D . discoideum " strains AC4 and ZA3A are also able to produce macrocysts.
• A homothallic strain of Closterium forms selfing zygospores via the conjugation of two sister gametangial cells derived from one vegetative cell.
• In " D . mucoroides " ( DM7 ) homothallic mating, cells are directed towards sexual development by ethylene.
• Conjugation in the homothallic strain occurs mainly at low cell density and is regulated by an ortholog of a heterothallic sex-specific pheromone.
• When incubated with their bacterial food supply, heterothallic or homothallic sexual development can occur, resulting in the formation of a diploid zygote.
• Up until 2010, all truffle species were thought to be homothallic, that is, capable of sexual reproduction from a single organism.
• Instead, the lichen-forming fungi of these species reproduce sexually by self-fertilization ( i . e . they are homothallic ).
• Among those " Aspergillus " species that exhibit a sexual cycle, the overwhelming majority in nature are homothallic ( self-fertilizing ).
• In contrast, homothallic species display the oogonia and antheridia on either the same hyphal branch or on separate hyphal branches but within the same colony.
• 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.
