Biochemistry of Russian wheat aphid resistance in wheat: involvement of lipid-like products
(University of the Free State, 2007-11-03)
Physical damage and disease are known to cause changes in the lipid composition of plants. The biochemical pathways that lead to changes in the lipid composition were investigated in a comparative study using Russian wheat ...
Genetic variability for Russian wheat aphid, Diuraphis noxia resistance in South African wheat genotypes
(University of the Free State, 2006-07)
Near-isogenic genotypes 1684/Tugela and 2199/Tugela containing D. noxia resistance ex SA1684 [PI 137739 (Dn1)] and SA 2199 [PI 262660 (Dn2)] were studied in terms of antibiosis, antixenosis and tolerance, population ...
Aspects of ß-1,3-glucanase expression in wheat associated with Russian wheat aphid resistance
(University of the Free State, 2003-11)
The aim of the study was to learn more about the expression of b-1,3-glucanase during the resistance response of wheat to the RWA (Diuraphis noxia)(Mordvilko). The different resistance genes (Dn1, Dn2 and Dn5) used in the ...
