Inheritance of resistance in two Triticum aestivum lines to Russian wheat aphid (Homoptera: Aphididae).
Resistance reactions of backcross, F2 and F3 seedlings in greenhouse tests indicated that resistance in each line is controlled by a single dominant gene and that these genes are independently inherited.
Development rate, fecundity and lifespan of apterae of the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae), under controlled conditions
The rate of development, fecundity and lifespan of apterae of Diuraphis noxia (Mordvilko) were determined at five sets of temperature and daylength conditions. The time required to complete
Association of a stem rust resistance gene (Sr45) and two Russian wheat aphid resistance genes (Dn5 and Dn7) with mapped structural loci in common wheat
The Russian wheat aphid resistance gene, Dn5, was loosely linked (32 ± 5 map units) to Ep-D1b, which occurs on a translocation derived from T. ventricosum, and to the cn?D1 locus on chromosome arm 7DL.
Chromosomal location of the Russian wheat aphid resistance gene, Dn5
An attempt was made to physically map the Dn5 gene employing the same source material previously used to describe, name, and map it and it was possible to derive monotelosomic 7DL plants carrying Dn4 on the telosome but such plants could not be developed for the short arm.
Targeting glycolysis in the malaria parasite Plasmodium falciparum
A weakness in the P. falciparum pathway design with respect to stability towards perturbations in the ATP demand is identified in a broader comparative analysis of glycolytic models.
Perceptions of effective relationships in an institutional care setting for older people
Orientation: The relocation of older people to residential facilities has implications for their relationships. Research purpose: This article reports older residents’ perceptions of effective
Constitutionalism, public policy and discriminatory testamentary bequests - a good fit between common law and civil law in South Africa's mixed jurisdiction
This Article investigates South African courts’ treatment of discriminatory testamentary bequests in the preand post-constitutional eras. It shows a change in judicial attitude towards such bequests
