Characterization of some early defence responses of leaf rust-infected wheat
(University of the Free State, 2007)
The aim of this study was to investigate the early events following the infection of wheat with leaf rust. An attempt was made to identify and characterize genes putatively involved in these early events. More specifically, ...
Proteomic analysis and physiological response of wheat treated with a triglyceride purified from Lupinus albus L. seed
(University of the Free State, 2013)
English: The agricultural use of bio-stimulants to increase crop yield is increasing as a result of the ever growing human population. Since bio-stimulants do not have the negative environmental effects usually associated ...
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 ...
Combining wheat rust and fusarium head blight resistance genes and QTL using marker-assisted selection
(University of the Free State, 2014-01)
English: Wheat (Triticum aestivum) is one of the most important cereal crops worldwide and cultivated in a wide range of environments. The production of wheat, based on consumption and other demands, needs to be increased ...
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 ...
Targeting quantitative trait loci for adult plant stripe rust resistance in wheat
(University of the Free State, 2007-11)
English: Stripe rust, caused by Puccinia striiformis West. f. sp. tritici is one of the most damaging
diseases of wheat (Triticum aestivum L.) globally. The South African wheat cultivar Kariega
expresses APR and has ...
Molecular markers for and quality assessment of near isogenic palmiet and SST66 wheat lines for Pmeudocercosporella herpotrichoides (eyespot) resistance
(University of the Free State, 2000-11)
English: 1. The aim of this study was to determine whether the presence of the Pch 1
gene, has an effect on breadmaking quality and yield in two genetic
backgrounds, to find a molecular marker linked to the gene, using ...
Isolation and characterization of a possible polygalacturonase: inhibiting protein from wheat
(University of the Free State, 2001)
English: The presence and possible role of polygalacturonase-inhibiting protein (PGIP) in
wheat (Triticum aestivum) as part of the plant's defense reaction following leaf rust
(Puccinia triticina) infection were ...
Molecular and biochemical characterisation of rust and Fusarium head blight resistant wheat lines
(University of the Free State, 2013-06)
English:
Wheat is one of the most important food crops and consumption in the past year was higher than production worldwide, which indicates improved wheat cultivars need to be developed to maintain the demand for wheat. ...
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 ...
