-
(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, 2011-09-23)
-
(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, 2010)Sirex noctilio is a major pest to Pinus spp. and threat to the Forestry industry in the Southern Hemisphere. The varying level of efficacy of its primary biological control agent, Deladenus siricidicola, is also of serious ...
-
(University of Pretoria, 2009-10-29)Although the genetic aspects of mating are a rapidly expanding field of study, little information is available for the genus Ophiostoma. The first MAT information for the genus focussed on only three species and this was ...
-
(University of Pretoria, 2009)Leptographium is an anamorph genus within the Ophiostomatoid group of fungi and represents a unique case for molecular applications. The genus has a near complete sequence data available for three genes across all known ...
-
Mating locus structure in Ceratocystis moniliformis and a gene duplication in Ceratocystis species (University of Pretoria, 2014)No abstract
-
(University of Pretoria, 2011-02-08)Reproductive isolation is an essential stage in speciation. In Ascomycetes, the ubiquitous distribution of many species suggests that sympatric speciation through assertive mating should be an important factor. The MAT ...
-
(University of Pretoria, 2012-08-14)Ceratocystis fimbriata is the type species for the genus Ceratocystis and was first described as the causal agent of black rot in sweet potatoes. However, evidence from DNA sequence data suggests that C. fimbriata is in ...
-
(University of Pretoria, 2013)The objective of this study was to characterize the mitochondrial genomes of the species within the genus Ceratocystis and investigate the evolutionary process of the ribosomal RNA cistron found within these fungi. ...
-
(University of Pretoria, 2007-02-13)Armillaria spp. are important root pathogens that cause considerable plant mortality throughout the world. The nomeclatural and taxonomic placement of the genus has been intensely debated for a long time. Early identification ...
-
(University of Pretoria, 2003)Coniothyrium zuluense is the causal agent of a serious Eucalyptus stem canker disease in South Africa (Wingfield et al., 1997). Eucalypts are the most important hardwood plantations in the world, and in South Africa these ...
-
(University of Pretoria, 2006-05-20)The main objective of this thesis was the elucidation of the host-pathogen interaction between Pinus patula and Fusarium circinatum. This was accomplished by studying differential gene expression at the molecular level. ...

Molecular phylogenetic studies on Armillaria with specific reference to Southern Hemisphere species (University of Pretoria, 2005-05-19)Please read the Summary in the section 00front of this document
-
(University of Pretoria, 2005-09-06)Please read the summary in the section 00front of this document.
-
(University of Pretoria, 2000)Cryphonectria canker of Eucalyptus, caused by Cryphonectria cubensis, is considered to be one of the most important fungal diseases affecting Forestry in South Africa. This disease also occurs in other tropical and ...
-
(University of Pretoria, 2006-11-30)Phytopathogenic fungi parasitise plants for survival. Knowledge of the interactions between plants and these fungi is of importance in designing control strategies. In this thesis the interactions of Eucalyptus ...
-
(University of Pretoria, 2013)Ceratocystis is a genus of Ascomycete fungi residing in the family Ceratocystidaceae (Order: Microascales; Class: Sordariomycetes). Species of Ceratocystis are best-known as woundinfecting fungi, which are mostly carried ...
