TransgenicArabidopsis tester lines with dominant marker genes

Molecular and General Genetics MGG, 1996
The map positions of a set of eight T-DNA insertions in the Arabidopsis genome have been determined by using closely linked visible markers. The insertions are dispersed over four of the five chromosomes. Each T-DNA insert contains one or more of the chimeric marker genes neomycin phosphotransferase (neo), hygromycin phosphotransferase (hpt ...

Genetic mechanisms for dominant VH gene expression. The VHB512 gene.

The Journal of Immunology, 1992
Abstract A total of 37 mAb with reactivity for dextran B512 have been studied; 30 of them were products of independent rearrangements and 21 made use of the same VH gene, the VHB512 gene. These results unambiguously established that the immune response to dextran in the high responder mouse strain C57BL/6 was restricted.

Testing for the presence of a partially penetrant dominant gene

Mutation Research Letters, 1983
Favor, in the Appendix to a paper by Ehling and his collaborators (Ehling et al., 1982), develops a method that tests for the presence of a partially penetrant dominant cataract mutation in a suspected parent (showing lens opacity) outcrossed to a homozygous strain-101 mouse when no individual with lens opacity is observed in the progeny.

Functional dominance among Hox genes: repression dominates activation in the regulation of dpp

Development, 1998
ABSTRACT Here we investigate the mechanisms by which Hox genes compete for the control of positional identity. Functional dominance is often observed where different Hox genes are co-expressed, and frequently the more posteriorly expressed Hox gene is the one that prevails, a phenomenon known as posterior prevalence.

Polyoma tumorigenesis in mice: Evidence for dominant resistance and dominant susceptibility genes of the host

Virology, 1992
We have determined the tumor responses of nine inbred mouse strains and of two F1 hybrids following inoculation with polyoma virus. The results showed wide variations in the frequencies of mice developing tumors. Correlation with H-2 haplotype were evident.

On survival probabilities of mutant genes and the evolution of dominance

Theoretical Population Biology, 1976
Abstract Intrinsic biological resemblance between two types is measured in terms of a correlation between their fitnesses under various possible environmental conditions. A tendency toward dominance is defined as the intrinsic biological resemblance between homozygote and heterozygote.

Dominant maternal interactions with Drosophila segmentation genes

Roux's Archives of Developmental Biology, 1988
A systematic search for X chromosome loci showing a dominant maternal interaction with the segmentation genes Krüppel, hunchback, knirps and hairy was performed using deficiencies spanning 65% of the X chromosome. No interaction with the knirps gene was observed, but five regions of the X chromosome showed a maternal dominant interaction with the ...

Maximum Rate of Selection for Dominant Quantitative Genes

Nature, 1946
THE following formulae are proposed to measure the maximum rate of progress of selection for dominant quantitative genes. To simplify the problem, certain assumptions are made: (1) Selection begins in the F2 generation of a cross between two pure lines. (2) All genes are dominant in the positive direction.

pac Gene as Efficient Dominant Marker and Reporter Gene in Mammalian Cells

1992
Publisher Summary This chapter discusses the pac gene as efficient dominant marker and reporter gene in mammalian cells. The usefulness of a new dominant marker, such as pac gene, must be evaluated in the frame of other available ones. In view of its versatility, the only sensible comparison should include other antibiotic resistance markers, such as
