High impact information on Hybrid Vigor

  • Molecular basis for heterosis for myelin basic protein content in mice [1].
  • We therefore believe that heterosis for brain MBP content in the F1 hybrid may be regulated at the transcriptional or post-transcriptional level [1].
  • However, Esr2(+/-) mice do develop more severe clinical disease with an earlier onset indicating that heterosis at Esr2 plays a significant role in regulating EAE in males [2].
  • We propose that heterosis provides a mechanism to compensate for UCP1 deficiency [3].
  • Specificity controls eliminate the possibility that the differential uptake is due to Fc receptor binding or undefined effects of hybrid vigor [4].

Associations of Hybrid Vigor with chemical compounds

  • The results for both the DRD1 and DRD2 genes, which have opposing effects on cyclic AMP, were consistent with negative and positive heterosis, respectively [11].
  • It was concluded that multilocus probe DFP of pooled DNA samples show promise as predictors of heterosis [12].
  • F1 hybrids of crosses between two widely studied wild-type strains, N2 (var. Bristol) and Berg BO (var. Bergerac), were examined for rate of development, hermaphrodite fertility, and behavior; there was no heterosis for these life history traits [13].
  • Analysis of the whole brain for several myelin-associated constituents such as GM1 ganglioside, 2',3'-cyclic nucleotide 3'-phosphohydrolase (CNPase), 5'-nucleotidase, and carbonic anhydrase indicated that heterosis exists for these components [14].
  • Similarity indices between different parental combinations, calculated based on seed esterase polymorphism, showed a significant negative correlation (r = -0.479, P = 0.05) with heterosis for carotenoid content [15].
 

Gene context of Hybrid Vigor

  • The possible role of HUMMLC2B and its relation to porcine heterosis are discussed [16].
  • The positive heterosis effects with respect to nicotine addiction and personality support the idea that the TPH1 gene exerts pleiotropic effects [17].
  • With one exception, heterosis was not an important source of variation for shank width or shank depth and there was a low level of heterosis for shank length [18].
  • Heterosis was 8.2% for ADG [19].
  • Heterosis percentages were significant for AVBF (7.2%; P less than .01), BF10 (8.8%; P less than .01), DRS% (1.5%; P less than .01), ADG (11.5%; P less than .01), DFC (10.2%; P less than .01), LNGN (10.6%; P less than .01), and LNEF (6.0%; P less than .05) [20].
