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’.

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.

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.
Born in Germany.
Julia Kreiss lived in South Africa from 2005 to 2008 together with her mycologist husband, Wolfgang Mayer, while his was doing research on rust fungi in FABI as a postdoctoral fellow.
Prior to their time in South Africa, Julia received her formal training in Classical Art Restoration in Germany. However, after spending one year on restoring a one square meter roof painting in a gothic cathedral, her creative spirit became frustrated and she started teaching art to children. During her stay in South Africa, FABI commissioned her to create the artwork for three of FABI’s annual Seasonal Greeting cards on themes related to research projects in FABI. The works on display are the original works created for these cards.

Born in 1942, Vryheid, KwaZulu Natal - died in 1999.
Sibiya was inspired from an early age by ideas of the mystical and abstract as a result of frequent visits with his father to the Sangoma. The boy would ‘borrow’ some of the healers’ artefacts, attempt to recreate them at home, and return them promptly before anyone would notice their disappearance.
Sibiya grew up in the colourful neighbourhood of Sophiatown, but due to the politically motivated destruction of the area the 1950s, his family had to relocate to Soweto. He went to school in Hammanskraal where the young boy experimented with woodcarvings. Before completing his school education, Lucky introduced himself and some of his painted 'found' objects to Cecil Skotnes, who was at the time one of South Africa's foremost contemporary artists. Skotnes was head of the Polly Street Art Centre in Johannesburg and was eager to accept Sibiya as a private pupil.
Sibiya took folklore and traditional mediums and images to a new level of sophistication. However, they maintained their raw and ritualistic feel. Over time, his wood carvings evolved towards his distinctive engravings, coloured by rubbing powdered pigments into them.
Lucky Sibiya’s works are still some of the most distinct and desirable throughout the art community, and exhibited in many galleries.
Born 1945, Ghanzi district, Botswana - died 1995.
The San artist Qgoma Ncokg’o was a participant of the Kuru Art Project (see below). Art was not his primary occupation and his works are rarely seen or exhibited. In 1993 one of his artworks was chosen as theme for a postal stamp of Botswana.
As a typical San artist he was fascinated by nature. He tried to capture his own perception of nature on paper as replacement for the traditional rock. His works also depicts the spiritualism of his tribe that revolves largely around natural objects.
KURU ART PROJECT
The Kuru Art Project is a project of a community trust called the Kuru Development Trust. It is situated in D’Kar, a small settlement in western Botswana. In contemporary Africa, the San artists of the Kuru Art Project bring back the role of art as an expressive outlet for their traditions and recent life experiences, as their ancestors had done in the many rock paintings all over Southern Africa. The Kuru Art Project encourages and assists these artists by exposing them to contemporary art materials and techniques and the administration and marketing of their art which became a much needed economic resource for this group of artists and their community.
Born in 1969, Twee Rivieren, Kgalagadi Transfrontier Park National Park - died in 2007, on the farm Blinkwater where he lived, just outside the Park.
Vetkat Kruiper Regopstaan Boesman was a member of the Khomani San tribe who lived in the now Kgalagadi Transfrontier Park. His father was a healer and crafter in his community, and clearly had a huge impact on Vetkat’s knowledge and understanding of San culture and customs. He is one of very few San artists who sustained the ‘lost’ (according to some) tradition of San rock art, but with ink on paper as medium. The animality, spirituality and symbolism in Vetkat’s works has been the topic of several academic studies (see below).
Vetkat’s works are in private collections at the Natal Museum Services, the McGregor Museum at Kimberley and the University of Pretoria. From 2002 to 2005 his art was displayed at the United Nations (UN) as part of an exhibition of indigenous art, while his 2004 tour of the United States of America culminated in his addressing the UN.
Shortly before his death in 2007, Vetkat was invited by the Department of Built Environment at the University of Pretoria to do a solo exhibition on the UP campus. All the works on exhibit were purchased by the University, and constitutes the largest assemblage of the artist’s works in a single collection.
