(University of Pretoria, 2019-11)African horse sickness virus (AHSV) is an orbivirus in the Reoviridae family that causes severe disease in horses, with major economic implications. The viral genome consists of ten double-stranded RNA segments, encoding ...
-
(University of Pretoria, 2019-09)The Botryosphaeriaceae is a large family of fungi including many plant pathogenic species that cause diseases of important plants such as fruit trees, grapevine, eucalypts, pines and wheat. Members of this family are ...
-
(University of Pretoria, 2020-02)South African forests have become fragmented due to both historical events and current human activities. Fragmentation may have increased population differentiation by reducing the gene flow between plants isolated in ...
-
(University of Pretoria, 2019-12)The global avocado industry has experienced significant growth throughout the past two decades, with annual production doubling over that time. However, increased production is accompanied by an ever-increasing threat from ...
-
(University of Pretoria, 2020-01)When a trait enhances fitness and arose as a result of natural selection, it is termed an adaptation. The optimization strategy employs selection thinking which makes the explicit assumption that the globally best trait ...
-
(University of Pretoria, 2020-01)Trees play a pivotal role in the global carbon cycle through the fixation and storage of carbon as polysaccharide and phenolic biopolymers in the secondary cell walls of xylem fibre cells (wood). Driven by the need to ...
-
(University of Pretoria, 2020-01)In the mid-2000s an outbreak of bacterial blight and dieback caused by Xanthomonas vasicola pv. vasculorum was observed on a single Eucalyptus grandis clone in KwaZulu-Natal. It was suggested that this outbreak was as a ...
-
(University of Pretoria, 2019)Addressing the concerns of microbial diseases affecting natural forests, particularly those caused by wood-rotting Basidiomycetes, is of paramount importance for the protection of these woody ecosystems. This is of particular ...
