What's the difference between autogamy and conjugation?

Autogamy


Definition:

  • (n.) Self-fertilization, the fertilizing pollen being derived from the same blossom as the pistil acted upon.

Example Sentences:

  • (1) This study examines the consequences of nutritional down-shift at various points within the cell cycle on the occurrence of autogamy.
  • (2) The clonal age in paramecia refers to the total number of vegetative divisions a clone has undergone since its origin at autogamy (self-fertilization).

  • (11) Autogamy, which leads to complete homozygosity, guarantees the expression of recessive mutations.
  • (12) Since micronuclei were not transplanted, the phenotypic reversion after autogamy is to be expected, and demonstrates that the transformation affects the macronucleus only.
  • (13) Processing of micronuclear DNA into new macronuclear DNA at conjugation and autogamy is under the control of the old macronucleus, and newly forming macronuclei become exactly like the old.
  • (14) Autogamy, which was checked with two closely linked marker genes, was frequent, but only during the period when lines were terminating.
  • (15) No degeneration of cilia is observed in natural autogamy of P. tetraurelia, whereas in chemically induced autogamy of P. caudatum degeneration occurs as in ordinary conjugation.
  • (16) Autogamy is a process of meiosis and fertilization which takes place in unpaired Paramecium cells, and which is triggered by starvation.
  • (17) If, however, the hybrid cell lines are brought to autogamy (which discards the existing macronucleus and forms a new one from sexual products derived from a micronucleus), then the lines revert to the ftA phenotype.
  • (18) If cells are refed at this point, or at later stages, autogamy continues.
  • (19) The level of starvation required for initiation of autogamy decreases progressively as cells age.
  • (20) Transfer of macronucleoplasm from the wild type to strain d48 caused d48 to revert to the wild type after autogamy.

Conjugation


Definition:

  • (n.) the act of uniting or combining; union; assemblage.
  • (n.) Two things conjoined; a pair; a couple.
  • (n.) The act of conjugating a verb or giving in order its various parts and inflections.
  • (n.) A scheme in which are arranged all the parts of a verb.
  • (n.) A class of verbs conjugated in the same manner.
  • (n.) A kind of sexual union; -- applied to a blending of the contents of two or more cells or individuals in some plants and lower animals, by which new spores or germs are developed.

Example Sentences:

  • (1) Mannose receptor mediated uptake by the reticuloendothelial system has been suggested as an explanation for the rapid removal of ricin A chain antibody conjugates from the circulation after their administration.
  • (2) Analysis of conjugated discharges ACHs showed that they appeared predominantly periodically (87% of cases).
  • (3) However, when conjugated to an antigen-bearing cell, a "non-antigen bearing" cell was labeled near the cell interaction area.
  • (4) This doxorubicin derivative did not bind to Sepharose which was conjugated with cardiac actin.
  • (5) Substances with a leaving group at the C-3 position form unsaturated conjugated cyclic adducts and are mutagenic only in the His D3052 frameshift strains with an intact excision repair system (no urvA mutation).
  • (6) Foreign antigens conjugated to alpha-2-Macroglobulin (alpha-2-M) were effectively taken up by murine macrophages via alpha-2-M receptors.
  • (7) Conjugational recombination in Escherichia coli was investigated by monitoring synthesis of the lacZ+ product, beta-galactosidase, in crosses between lacZ mutants.
  • (8) Cloned genes encoding pertussis toxin from B. pertussis were transferred into Bordetella bronchiseptica and Bordetella parapertussis by conjugation.
  • (9) Rates of PC in vitro metabolism by liver and kidney cytosolic cysteine conjugate beta-lyases (beta-lyases) were similar, but metabolism by renal mitochondrial beta-lyase occurred at a 3-fold higher rate than the rate obtained with hepatic mitochondrial beta-lyase.
  • (10) Additionally, cats excreted the taurine conjugate of hydratropic acid.
  • (11) This paper examines the chiral nature of the covalent conjugates formed upon reaction of acetylcholinesterase (AchE) with enantiomeric cycloheptyl, isopropyl, and 3,3-dimethylbutyl methylphosphonyl thiocholines.
  • (12) We evaluated the safety and efficacy of a conjugate vaccine that links the H. influenzae type b capsular polysaccharide to the outer-membrane protein complex (OMPC) of Neisseria meningitidis serogroup B.
  • (13) This fact suggested that TCTFP may be metabolized intensively by glutathione (GSH) conjugation and therefore, like hexachlorobutadiene, would be expected to be nephrotoxic.
  • (14) Bile flow was stimulated significantly by VPA and MCCA, but not by CCA; changes in bile flow correlated with the biliary excretion rate of base-labile conjugates rather than with excretion of the parent compounds themselves.
  • (15) In addition, a beta-linked sialic acid:nucleoside conjugate (Kl-8111) and an equimolar mixture of Kl-8110 and Kl-8111 (Kl-414) also inhibited the metastatic ability of NL cells to the same extent as Kl-8110 did.
