The potential economic impact of the PSHB invasion in South Africa has been calculated to be a massive R275 billion over the next ten years, if nothing is done to stop the spread of this invasive beetle. Researchers from FABI collaborated with Stellenbosch University ecologists and economists to model the unmitigated economic impact of this invasion.
A recently published paper in the journal Current Forestry Reports documents a collaboration between an international team of forest pathologists and invasion scientists. Led by Dr Trudy Paap, the authors present a framework for conceptualizing and managing invasive forest pathogens.
A recently published review article by Dr Andi Wilson in a special issue of the journal 'Microbiology & Molecular Biology Reviews' provides details of the genes that are essential to the sexual cycle in filamentous Ascomycete fungi and further describes their functions in a variety of model and non-model species.
Penicillium section Canescentia re-evaluated and five new species described from the fynbos biome in South Africa.
In November 2019, the DSI-NRF Centre of Excellence for Invasion Biology hosted a workshop on ‘Frameworks used in Invasion Science’. The workshop led to a NeoBiota special issue on this theme, and includes a review by FABI researchers and international colleagues, exploring frameworks in the context of forest pathology.
A doctoral study in FABI confirms for the first time the presence of Xylosandrus crassiusculus, a polyphagous ambrosia beetle and its fungal symbiont, Ambroseilla roeperi, in three provinces in South Africa. The authors warn that this beetle species could be a threat to native and plantation trees.
A review on invasive gall-forming wasps that threaten non-native Eucalyptus plantations by researchers in the TPCP appears in Agricultural and Forest Entomology. They profile several species of likely Australian origin that have established on non-native Eucalyptus plantations globally and discuss various challenges to their management.
A study in the TPCP confirms the identity of seven novel fungal species associated with Dendroctonus valens, the red turpentine beetle. The study follows on surveys on the fungal associates of the beetle in China and North America. Results from this work appear in Persoonia.
A postdoctoral study in the TPCP describes two novel Huntiella species in the African clade, bringing the number of known species in the genus to 31. Though closely related, the two species display different mating systems. Outcomes from this study appear in the journal MycoKeys.
A review of the invasion history and global management strategies of Eucalyptus snout beetles in the Gonipterus scutellatus species complex by researchers in the TPCP appears in the Journal of Pest Science.
In a collaborative venture with Dr Jos Houbraken (Westerdijk Fungal Biodiversity Institute, the Netherlands), Prof. Cobus M Visagie, Dr Neriman Yilmaz (both from FABI) and others have recently completed and published a major study updating the taxonomy of the Eurotiales.
A study in the Forest Molecular Genetics (FMG) Programme at FABI interrogates the benefits of implementing genomic selection for growth and wood quality traits in an established Eucalyptus grandis breeding programme in South Africa. Outcomes from this study appear in an article.
The first study on alternative weed and cultivated hosts of Spongospora subterraneaf. sp. subterranea (Sss), in southern Africa identifies two species as ideal trap crops for rotation with potatoes. The study also introduces three new families to the known hosts of Sss in the region.
A consortium of microbiologists from around the globe, FABI included, is pushing for an overhaul in how scientific names are assigned to uncultivated bacteria and archaea. Despite their ecological, agricultural and medical importance, these organisms traditionally have not been recognized by the international body governing the nomenclature of prokaryotes.
Professor Cobus Visagie is a researcher in the Applied Mycology group at FABI. One of the group’s research goals is to discover fungal diversity in South Africa, and Cobus’ research is strongly focussed on the economically important genera Aspergillus, Penicillium and Talaromyces.
Postdoctoral research by Dr Norman Muzhinji in the Potato Pathology Programme at the Forestry and Agricultural Biotechnology Institute (FABI) sheds light on the genetic structure and diversity of Spongospora subterranea f. sp. subterranea in four potato-growing regions in South Africa, providing valuable insights on its management.
An MSc study by Kira Lynn in the RGE-FABI Tree Health Programme at the University of Pretoria has described a new Fusarium species, Fusarium rekanum sp. nov., associated with Euwallacea perbrevis, an ambrosia beetle species infesting Acacia crassicarpa plantations in Riau, Indonesia.
FABI postdoctoral Fellow Dr Andi Wilson has established a CRISPR-Cas9-based genome editing protocol for use in Huntiella omanensis, a tree-inhabiting fungus belonging to the Ceratocystidaceae family.
Research undertaken as part of a PhD study by Molly Malefo at the University of Pretoria’s Department of Plant and Soil Sciences and Forestry and Agricultural Biotechnology Institute sheds more light on the role of protease inhibitors in plants under drought stress.
The South African National Biodiversity Institute (SANBI) has funded a postdoctoral research project dedicated to monitoring plant health in botanical gardens and arboreta across South Africa. Two postdoctoral Fellows at the University of Pretoria’s Forestry and Agricultural Biotechnology Institute have held these fellowships.
The first comprehensive study mapping the distribution and genetic diversity of invasive Eucalyptus insect pests in sub-Saharan Africa confirms the presence of five major foliage-feeding species in 14 countries. The results of this study have implications on the quarantine, future research and management of these pests on the continent and beyond.
Dr Joey Hulbert broke new ground when he became the first candidate at the Forestry and Agricultural Biotechnology Institute to complete a PhD study incorporating citizen science. Citizen science is an approach that involves members of the public as active participants in scientific research.
FABI technology unravels the genetics behind fungal genome evolution The RIPper is a bioinformatics tool for the for quantifying genome-wide RIP mutations in fungal genomes. The strength of this software lies in the automation of laborious techniques to study the mutation process called Repeat-Induced Point mutations (RIP). The RIPper applies these technique
With the increased availability in genome data, inferences regarding evolutionary relationships among taxa can now be performed on a genome-wide scale. But it is widely accepted that not all parts of such massive datasets support the same evolutionary hypothesis. Because of this, a group of researchers at FABI recently investigated the effect of this.
The use of genome data to characterize species and elucidate relationships, particularly between problematic taxa, has become routine practice in bacteria. Recently, researchers from FABI joined in an international effort to describe two novel genera and characterize these within the larger context of the important bacterial group Burkholderia.
A PhD student in FABI, Runlei Chang, has discovered and described 19 new fungal species from China as part of the research for his thesis. These fungi are all associated with conifer-infesting bark beetles and their mites and belong to well-known genera such as Ophiostoma and Leptographium.
Two research papers from FABI were selected as cover stories in two consecutive issues of the international journal, Plant Pathology. The journal is published by Wiley for the British Society of Plant Pathology.
Plastids play an integral role in wood formation, and yet they are routinely ignored in the study of xylogenesis in forest trees. Desre Pinard and Dr Eshchar Mizrachi have published a review highlighting the unique biology of plastids in wood, suggesting that a new type of plastid, the xylopast, exists.
Approaches for characterizing metabolic potential from genomic sequences have previously been predicted to be useful in the description of bacterial taxa. Dr Marike Palmer, has recently employed these approaches for identifying biological processes contributing to the divergence of bacteria with a variety of lifestyles.
Comparative genomics is shaping our notion of what fungal species are. Based on current data, these unique evolutionary units are separated from one another by boundaries that are porous under certain conditions. This affects our expectations regarding their population biology and evolution, and our strategies for recognizing and controlling them.
The Polyphagous Shot Hole Borer is an ambrosia beetle native to Southeast Asia. In 2017 this pest was detected in South Africa. Its presence has since been confirmed in all provinces except Limpopo. The beetle has a symbiotic relationship with the fungus Fusarium euwallaceae, which causes branch die-back and death of susceptible trees.
What to look for and collecting samples
Disease infection and spread
Ceratocystis species are fungal pathogens that affect mostly woody plant species.
Infection occurs through natural openings (buds, cracks in bark, root knots etc.) or external wounds on the stems or roots, induced through cultivation practices (e.g. grafting and pruning wounds), insects or weather-related conditions. The fungus invades the plant and blocks the water transport system resulting in wilting symptoms.
The spores of the fungus can be distributed via insects (e.g. picnic beetles or flies) by attaching to the insects which then transmit these spores from diseased to healthy plants. Some insect vectors bore into the diseased tissue of plants and the contaminated frass (borings) can be distributed via wind and rain.
Spread also occurs through the movement of infected plant material and soil. The thick fungal spore form can survive for long periods of time in the soil and infect new plants planted in the same soil.
Symptoms
Symptoms of infected plants include leaf discolouration (yellowing) and wilting (a) which can eventually lead to plant death (b).
Internal infections in the cane/trunk are visible as dark brown streaks or mottled spots in the wood(c,d,e,f,h) or roots (g).
Collecting samples for diagnosis
When wilting symptoms appear, inspect both rootstock, especially at the soil level, and recently wilted canes. Cutaway bark and look for streaking of wood (c,d,e,h).
Cut infected cane tissue at the margins of healthy and dying tissue or shave off thick pieces of discoloured wood with symptoms. Wrap samples from individual plants separately in newspaper and place them in separate plastic bags. Document variety number on bags. If roots are infected, first wash off soil and dry samples before wrapping in newspaper.
Take clear photos of symptoms (use images here as examples).
If any symptoms are seen at the root collar, take soil samples. Mix up the soil (top 10cm) from around the base of the plant. Place ONE CUP of this soil in a plastic bag and seal firmly.

Grain Crop Biotechnology Platform
Applied Mycology
In the Applied Mycology Research Programme, we are focusing on to better understand the fungal communities that produce mycotoxins in agricultural crops, food and animal feed. Emphasis is placed on the diversity and taxonomy of genera such as Alternaria, Aspergillus, Fusarium, Penicillium and Talaromyces, but many others are also studied. Ultimately, our goal is to secure food and feed from farm to fork for future generations.
Cereal Foliar Pathogen Research
The research group focusses on the interaction between cereal plants and foliar fungal pathogens. Pathosystems currently under study include grey leaf spot in maize (GLS) caused by Cercospora zeina, and northern corn leaf blight (NCLB) in maize and sorghum caused by Exserohilum turcicum. Projects are aimed at studying population structure of these pathogens, identification and functional characterisation of pathogen effectors causing disease, and cereal plants’ response to pathogen infection.
Crop Floral Biology and Environments
The Crop Floral Biology and Environments research team is focused on understanding how changing environments affect floral development, anthesis (flowering from bud opening to pollination) and pollination in economically important crops such as maize and sunflower. The multidisciplinary projects draw together aspects of climatology, plant physiology, plant molecular biology and ecology to holistically address these questions.
DST-NRF Centre of Excellence in Tree Health Biotechnology
The CTHB promotes the health of trees indigenous to South Africa through the use of biotechnology. This is accomplished through projects that typically consider the pathogens and pests associated with native trees and woody hosts. The CTHB also explores the possible effects that factors such as climate change, society, natural forest health and plant genetics may have on the health of native woody resources and ecosystems.
Grain Research Programme
The Grain Research Program (GRP) is a newly established programme that was developed by a team of multidisciplinary grain researchers from different institutes and programmes at FABI and elsewhere in South Africa. The GRP was formed to engage directly with grain stakeholders to initiate research that will support this sector by identifying future challenges to the industry and exploring solutions to these challenges. To its stakeholders in agriculture, the GRP also provides extension and disease/pest diagnostic services.
Molecular Plant Physiology
The Molecular Plant Physiology group collaborate with research groups in the UK, USA, Canada and Belgium to study the effect of biotic and abiotic stress in plants though a combination physiology, phenomics, functional genomics and proteomics. Using a holistic approach we aim to better understand the mechanisms underlying plant stress tolerance and resistance as well as the identification of potential biological markers that can then be used in plant improvement.
Molecular Plant-Pathogen Interactions
The Molecular Plant-Pathogen Interactions (MPPI) Group is located in the Plant Sciences Complex at the University of Pretoria and is headed by Prof Dave Berger. Research focuses on the molecular basis of plant-pathogen interactions using a range of approaches from whole plant phenotyping to functional genomics. We study the maize – grey leaf spot (Cercospora zeina) pathosystem.
Seed Science
The group is actively involved in seed science research. Our research fields include seed health tests, general seed pathology, seed vigour and seed germination according to ISTA rules. We are also involved in evaluating industry, or developing novel, environmentally sustainable, seed treatments. The research focuses on grains, herbs and vegetables.
Vegetable Crop Biotechnology Platform
Bacterial Genomics and Plant Pathogen Interactions
The bacterial genomics and host pathogen interactions research group is interested in understanding molecular pathogen-host interactions between potato plants and their various pathogens. The objectives of the research include molecular identification of potato pathogens and pests, functional characterisation of bacterial virulence factors and elucidation of potato plant responses elicited by potato pathogens. We ultimately endevour to contribute knowledge toward the control of pathogens and pests under study.
Potato Pathology Programme
The primary research focus of the Potato Pathology Programme is the epidemiology, diagnosis and control of soil- and seed-borne diseases of potatoes. Diseases currently being investigated include powdery scab, black scurf, stem canker, blackleg and soft rot. Various approaches are used to better understand disease spread and development, host-pathogen interactions and control, to provide growers with risk assessment and disease management strategies.
Fruit and Nut Crop Biotechnology Platform
Avocado Research Programme
Avocado Research Programme, a programme of the Forestry and Agricultural Biotechnology Institute (FABI), represents a cooperative venture between The Hans Merensky Foundation and the University of Pretoria, to deal with avocado disease problems, especially the avocado/Phytophthora cinnamomi interaction. HMF has committed a substantial amount to establish this research project at FABI and The University of Pretoria in turn provides the infrastructure necessary to conduct research.
DST-NRF Centre of Excellence in Plant Health Biotechnology
The CTHB promotes the health of trees indigenous to South Africa through the use of biotechnology. This is accomplished through projects that typically consider the pathogens and pests associated with native trees and woody hosts. The CTHB also explores the possible effects that factors such as climate change, society, natural forest health and plant genetics may have on the health of native woody resources and ecosystems.
Kiwifruit Protection Programme
The Kiwifruit Protection Programme (KPP) was established in February 2023 as a collaborative initiative between the South African Kiwi Growers Association and the Forestry and Agricultural Biotechnology Institute (FABI). This programme, under the primary leadership of Prof. Irene Barnes, aims to support local kiwifruit farmers by conducting research on pests and diseases of kiwifruit and providing an extension and disease/pest diagnostic service to the farmers.
Macadamia Protection Programme
Macadamia is one of the fastest growing agricultural industries in the country and is of economic importance to South Africa. The industry is however hampered by a number of pests and diseases which can cause major economic loss, both in terms of yield as well as nut quality. The industry currently relies heavily on the use of commercially available pesticides and chemicals for pest and disease control. There is, however, growing concern regarding continuous build-up of resistance, and the long-term sustainability of the industry is dependent on the use of integrated pest management.
Phytobacteriology
The Phytobacteriology programme at FABI has two main research areas, viz. taxonomy and pathogenicity. Several plant pathogenic bacteria are currently being characterized using a range of techniques, and are also being formally described. As one of our main focus areas, the pathogenicity factors of Panteoa ananatis, an opportunistic plant pathogen, are being investigated using a functional genomics approach.
