(University of Pretoria, 2005-05-20)Please read the summary in the section 02back (Appendix 1) of this document
-
(University of Pretoria, 2011-06-27)Diuraphis noxia Kurdjumov (Hemiptera: Aphididae: Macrosiphini) is a major agricultural pest that causes extensive economic losses to the wheat and barley industries. Resistant cultivars were relatively successful in ...
-
(University of Pretoria, 2011-08-06)DNA micro-array technology is a new and powerful technology that could substantially increase the speed of forest tree breeding programmes. This thesis represents a compilation of investigations that focus on the exploitation ...
-
(University of Pretoria, 2005-12-01)Factors that determine the molecular basis of African horsesickness virus (AHSV) virulence are unclear. Several proteins and different events in the viral replication cycle together with different environmental factors are ...

-
(University of Pretoria, 2007-11-08)VP6 is one of the minor structural core proteins of African horsesickness virus. The minor core proteins VP1, VP4 and VP6 are presumed to constitute the dsRNA dependent RNA polymerase transcription complex of the virus. ...

(University of Pretoria, 2006-06-19)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2018)Ticks and tick-borne diseases have a negative impact on the quality and quantity of livestockderived products. As such, effective control strategies against these parasites are needed. Currently, acaricides are the most ...
-
(University of Pretoria, 2018)The recalcitrance of lignocellulosic biomass to enzymic digestion remains a significant obstacle to the adoption of an environmentally and economically sustainable strategy for the synthesis of biomaterials. Traditional ...
-
(University of Pretoria, 2017)Facial appearance is thought to indicate immunity in humans, but very few studies have tested this relationship directly. The aim of the work in chapter 2 was to test the relationship between direct measures of immunity, ...
-
(University of Pretoria, 2014)Forests are complex ecosystems that provide a variety of valuable products, such as timber, fuel wood, fiber and non-wood forest products and they also contribute to socio economic development. Pest problems have a ...

(University of Pretoria, 2007-09-06)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2015)Lignocellulosic biomass is an important feedstock for the bioeconomy, particularly for biorefinery and biomaterial application. This is due to the characteristic secondary cell walls composed of a matrix of cellulose and ...
-
(University of Pretoria, 2014)Wood formation is heavily exploited for the manufacturing of pulp, paper, sustainable biomaterials and, potentially, biofuels. Eucalyptus is a favourable fast-growing, short rotation plantation crop grown over millions of ...
-
(University of Pretoria, 2005)Knowledge of the genetic variation of crop collections is essential for their efficient use in plant breeding programs. The Ethiopian Highland Maize Germplasm Collection Mission was launched throughout the highlands of ...
-
(University of Pretoria, 2012-09-14)The Gibberella fujikuroi species complex accommodates Fusarium spp. in the section Liseola that are unified by a common Gibberella sexual state. These are ubiquitous and economically important pathogens of plants, resulting ...
-
(University of Pretoria, 2016)Nesterenkonia sp. AN1 was isolated from soil samples obtained from the Miers Valley, McMurdo region in eastern Antarctica, where the organism survives under 'extreme' environmental conditions, including extreme cold, osmotic ...
-
(University of Pretoria, 2017)Microbial communities inhabit many environmental niches including the nutrient-rich gut systems of animals, where they are involved in a number of important processes. Insect gut microbiota may assist the host with several ...
-
(University of Pretoria, 2017)Breast cancer (BC) has become the leading cancer amongst women in South Africa. The overall life time risk for developing this disease is one in 12 (National Cancer registry, 2000- 2011). A strong family history (≥3 ...
-
(University of Pretoria, 2009)Individual-based simulation modelling is an excellent method for testing hypotheses, while including realistic and stochastic population parameters. This thesis considers the evolution of dispersal or inbreeding through ...
