Linkage disequilibrium mapping of the bolting gene in sea beet using AFLP markers
Genetical Research - Tập 77 Số 1 - Trang 61-66 - 2001
Mats Hansen, Thomas Kraft, SARA GANESTAM, Torbjörn Säll, Nils‐Otto Nilsson
The possibility of using linkage disequilibrium mapping in natural plant populations was assessed. In studying linkage disequilibrium among 137 mapped AFLP markers in four populations of sea beet (Beta vulgaris ssp. maritima (L.) Arcang.) it was shown that tightly linked loci could be detected by screening for associations. It was hy...... hiện toàn bộ
A world-wide survey of genetic variation in the yellow fever mosquito,Aedes aegypti
Genetical Research - Tập 34 Số 3 - Trang 215-229 - 1979
Walter J. Tabachnick, Jeffrey R. Powell
SUMMARYThirty-four populations ofAedes aegyptirepresenting the world-wide distribution of the species, were analysed for genetic variation at 19–22 isozyme loci. The species has an average expected heterozygosity of 0·129±0·045 based on 19 loci analysed in every population. Based on this genetic information, two major groups can be define...... hiện toàn bộ
The use ofp-fluorophenylalanine with ‘master strains’ ofAspergillus nidulansfor assigning genes to linkage groups
Genetical Research - Tập 6 Số 3 - Trang 352-359 - 1965
Kevin K. McCully, Emma Forbes
Four ‘master’ strains ofAspergillus nidulans, three of which are marked on each of the eight chromosomes, are used for assigning genes of unknown location to linkage groups. In this technique a heterozygous diploid is synthesized between one ‘master’ strain and a strain carrying an unlocated marker. This diploid is haploidized by growth onp... hiện toàn bộ
Mitotic non-conformity inAspergillus: successive and transposable genetic changes
Genetical Research - Tập 16 Số 1 - Trang 79-93 - 1970
João Lúcio de Azevedo, J. A. Roper
SUMMARYStrains ofAspergillus nidulanswith, a duplicate chromosome segment are mitotically unstable; in addition to phenotypically improved variants, arising following deletions in either duplicate segment, they give morphologically deteriorated types, some with, enhanced stability. In one isolate, deterioration and increased instability w...... hiện toàn bộ
The production and replica plating of micro-colonies ofAspergillus nidulans

The two-way selection of mutants and revertants in respect of acetate utilization and resistance to fluoro-acetate in Aspergillus nidulans
Genetical Research - Tập 6 Số 3 - Trang 317-329 - 1965
David Apirion
An extension of two-way selection (i.e. selection of mutant from wild-type and vice versa within the same locus and with the same efficiency) to four different mutational or segregational situations was made possible by using acetate, fluoro-acetate and other substances related to their metabolism.Two types of mutants resistant to fluoro-acetate were selected, the first of...... hiện toàn bộ
The genetics of tasting in mice: V. Glycine and cycloheximide
Genetical Research - Tập 52 Số 3 - Trang 207-212 - 1988
Ian E. Lush, Gail Holland
SummaryGlycine tastes both bitter and sweet to mice but there are differences between strains in their ability to detect each taste. With respect to the bitter taste, fifteen strains were classified as tasters and twelve strains as non-tasters. The difference is due to a single gene, Glb (glycine bitterness). Cycloheximide tastes bitter t...... hiện toàn bộ
Non-stringent tissue-source requirements for BMP ligand expression in regulation of body size inCaenorhabditis elegans
Genetical Research - Tập 93 Số 6 - Trang 427-432 - 2011
Cathy Savage‐Dunn, Ling Yu, KWESI GILL, Muhammad Uzair Awan, Thilini R. Fernando
SummaryInCaenorhabditis elegans, the Bone Morphogenetic Protein (BMP)-related ligand Dpp- and BMP-like-1 (DBL-1) regulates body size by promoting the larval and adult growth of the large epidermal syncytium hyp7 without affecting cell division. This system provides an excellent model for dissecting the growth-promoting activities of BMP l...... hiện toàn bộ
Polymorphism from environmental heterogeneity: models are only robust if the heterozygote is close in fitness to the favoured homozygote in each environment
Genetical Research - Tập 45 Số 3 - Trang 299-314 - 1985
Rolf F. Hoekstra, R. Bijlsma, A. J. Dolman
SummaryThe lack of robustness of models of the maintenance of polymorphism in a heterogeneous environment which has been pointed out by Maynard Smith & Hoekstra (1980), applies also to models based on habitat selection, on temporal variation and on density-regulated selection. Only if (partial) dominance ‘switches’ between environments such that the fitness of ...... hiện toàn bộ
Polymorphism in a varied environment: how robust are the models?
Genetical Research - Tập 35 Số 1 - Trang 45-57 - 1980
J. Maynard Smith, R. Hoekstra
SUMMARYThis paper shows that a number of models of the maintenance of polymorphism in a heterogeneous environment, including those of Levene and Dempster, can be derived from a simple assumption about the way in which the numbers and kinds of individuals emerging from a niche depend on the number of eggs laid in it. It is shown that for such models, unless selectiv...... hiện toàn bộ
