-
(University of Pretoria, 2019)Pre-mature nodule senescence is a naturally occurring process that often has a negative impact on plant growth and development. Nodule senescence is regulated by a class of enzymes known as cysteine proteases. In this ...
-
(University of Pretoria, 2019)Medicinal plants are important and valuable natural resources. South Africa is well-endowed with very diverse flora and fauna that include a considerable number of medicinal plant species. Most medicinal plants have gained ...
-
(University of Pretoria, 2020)Increased demand for sustainably produced, healthy, and nutritious food has seen certain segments of the world agricultural sector flourish in the past few decades. The macadamia nut industry in particular has expanded at ...

(University of Pretoria, 2020)The Coalfields of the Republic of South Africa (RSA) discharge approximately 360 Ml d-1 of mine impacted water, referred to as Acid Mine Drainage (AMD), requiring neutralization to reduce risk to the environment. High ...
-
(University of Pretoria, 2020-08-12)The encroachment of rangelands by woody plants causes an imbalance in the grass:bush ratio leading to decline in ecosystem services including grazing capacity, biodiversity, and water yield. This study assessed the historical ...
-
(University of Pretoria, 2020-07-15)Numerous studies in high-Si accumulators found physiological and biochemical adaptation processes were enhanced by Si application in crops stressed by cold conditions. Meanwhile, there is relatively little information on ...
-
(University of Pretoria, 2020-08)World-wide population is rising, and pressure is mounting on already limited resources targeted for agricultural productivity. Resources like water and crop nutrient sources are getting limited every day to sustain the ...
-
(University of Pretoria, 2020)The Miombo woodland vegetation of southern Africa has been subjected to anthropogenic pressures in recent years, resulting in a change in its cover and floristic-structural composition, and the population status of important ...
-
(University of Pretoria, 2020-07-14)Abstract Management of the large Ntabelanga Catchment for development of a water reservoir in the Eastern Cape has to consider the scattered, very small and fragmented natural forests within the matrix of montane grasslands. ...
-
(University of Pretoria, 2020)Natural products derived from indigenous plant species continue to gain interest in the medicinal and cosmetics industries. This places pressure on plant populations and ecosystems. Therefore, this necessitates domestication ...
-
(University of Pretoria, 2019)Avocado is a globally significant fruit tree crop. However, Phytophthora root rot, caused by Phytophthora cinnamomi (Pc), is the primary limitation to production in most countries. This soil borne oomycete pathogen infects ...

-
(University of Pretoria, 2018)Maize and sugarcane production has been threatened by declining soil quality due to long-term unsustainable management practices, which have increased the reliance on inorganic fertilization. This study reports on long-term ...
-
(University of Pretoria, 2019)The discovery of antibiotics has been one of the major breakthroughs in the history of medicine for the treatment of microbe-related infections. Soil-borne microorganisms have been known to potentially produce clinically ...
-
(University of Pretoria, 2019)The prevalence of Zinc (Zn) deficiency in plants is a common global phenomenon. Soils with inherent low Zn contents are found, but it is often induced by high carbonate or organic matter contents in soils, high soil pH, ...
-
(University of Pretoria, 2019)Therapeutic recombinant proteins such as antibodies, hormones, enzymes, and anticoagulants can be used in medicine, for food production, agriculture and bioengineering industries. Recombinant proteins are currently being ...
-
(University of Pretoria, 2019)Wetland soils are highly effective ecosystems for long term storage of carbon. Prolonged periods of soil saturation stimulate high rates of productivity by appropriately adapted hydrophytic vegetation and cause a depletion ...
-
Rhizobacteria-induced priming against Fusarium crown rot and desiccation stress in Sorghum bicolor (University of Pretoria, 2019)Untargeted ultra-high performance liquid chromatography-high definition mass spectrometry (UHPLC-HDMS) based metabolomics was applied to elucidate the metabolomic changes in Sorghum bicolor seedlings that attribute to ...
-
(University of Pretoria, 2018)Over the last decade, Africa has been targeted by large-scale agricultural investments (LAIs) in the global rush for agricultural land and resources. This potential land use change has generated multifaceted and controversial ...
