What's the difference between zygosis and zymosis?
Zygosis
Definition:
(n.) Same as Conjugation.
Example Sentences:
(1) The results are discussed in terms of possible conjugation-associated changes that, at high Hfr to F(-) ratios, lead to lethal zygosis.
(2) Temporary sensitivity to lethal zygosis in these and in standard F(+) strains can be induced by the formation of F(-) phenocopies.
(3) The existence of SVP1 and at least two other fertility plasmids, SVP2 and SVP3, was detected in S. venezuelae by 'lethal zygosis' elicited by a plasmid-plus mycelium in contact with a plasmid-minus mycelium.
(4) A lethal zygosis-sensitive mutant of Streptomyces erythreus, ER720, was isolated.
(5) However, analysis of a series of strains with deletions in the F factor, extending from the right into the tra region, suggests that a gene for immunity to lethal zygosis is located within the tra region.
(6) We have suggested that there is an immunity to lethal zygosis (Ilz(+)) associated with the F factor and discuss the results in terms of this hypothesis.
(7) The relationship between lethal zygosis and the various stages of conjugation is discussed.
(8) The decrease of recombinants was accompanied by a less marked decrease of viability in the recipient population in a manner resembling lethal zygosis.
(9) Whereas most Hfr strains capable of producing normal yields of recombinants showed killing activity, no F(+) and only one F' donor produced lethal zygosis.
(10) A Rec+ recipient shows no lethal zygosis in these experiments performed without aeration.
(11) This phenomenon of lethal zygosis is associated with conjugation and is observed as a continuous fall in F(-) viable cells during liquid mating, or as inhibition of F(-) growth on solid media.
(12) Tracking of mitochondria of different genotypes was made possible by positive identification of each mitochondrial population before zygosis, and by the low degree of mixing (less than 10%) of mitochondrial populations before first bud septation.
(13) The clones isolated demonstrate one or more of the following F-specified functions: inhibition of female-specific phage (T7) multiplication, formation of F pili, surface exclusion, or immunity to lethal zygosis.
(14) The absence of lethal zygosis with filtrates and supernatant fluids from donors suggests a dependence on direct cell-cell contact as found in conjugation.
(15) Hfr, F+, and F-prime cells are, unlike F- cells, insensitive to an excess of Hfr donor cells, indicating that there is an F factor mediated immunity to lethal zygosis (I1z).
(16) pMEA100 was found to be self-transmissible, eliciting the lethal zygosis phenotype, and is possibly involved in fertility in N. mediterranei.
(17) Evidence is presented showing that lethal zygosis was accompanied by changes in the physiology of the recipient cells, including (i) inhibition of deoxyribonucleic acid synthesis, (ii) inhibition of beta-galactosidase induction, (iii) altered transport and accumulation of galactosides, and (iv) leakage of beta-galactosidase into the supernatant fluid.
(18) One class of survivors, which arose in the zones of inhibition on solid media, was no longer sensitive to lethal zygosis and exhibited the following properties: sensitivity to male-specific phage, donor ability, and surface exclusion.
(19) We have described and discussed the parameters affecting this phenomenon of lethal zygosis, and these include the cultural conditions of both donor and recipient cells prior to mixing and the use of aeration throughout the period of the experiment.
(20) pLG5 (5.5 kb) and pLG10 (6.5 kb) both carry the thiostrepton resistance (TsrR) and lethal zygosis (Ltz+) markers and have single cloning sites within a non-essential region and the tsr gene.
Zymosis
Definition:
(n.) A fermentation; hence, an analogous process by which an infectious disease is believed to be developed.
