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.

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.
Birth of a Symbiologist is autobiographical as well as an exposition of the process of science. As a child I was fascinated by nature. Early trips to second-hand stores and numerous camping trips provided me with a wealth of old books, magazines, and shoeboxes full of dried mushrooms, lichens, and rocks from which I pieced together an understanding of the natural world around me. These ‘found objects’ played a major role in who I would become as an adult. My development as a scientist was strikingly similar – taking knowledge developed by others in the past and adding bits and pieces I found along the way, I have emerged as a symbiologist. Unlike with insects metamorphosing from a cocoon with a predictable form, scientists emerge as a product of intention, imagination, and fortuitous encounters – each a very different animal.
Birth of a Symbiologist.
Born in Johannesburg, 1929. Died in Tulbagh, 2000.
From 1947 to 1959 Coetzee studied at the University of the Witwatersrand, and from 1951-1952 at Slade School of Art at the University in London, England.
Coetzee was an assemblage and Neo- Baroque artist, closely associated with avant-garde movements of Europe and Japan during the 1950s and 1960s. Coetzee’s first solo exhibition in Europe was held in March of 1955 at the Hanover Gallery in London. After a short stay in Italy, Coetzee was invited to Paris by the French critic, Michel Tapié de Ceyleran, who introduced him to the owner of the Galerie Rive Droite. Coetzee worked in Paris for the majority of the next ten years under the guidance of Tapié, and in collaboration with Galerie Stadler. In 1959 Coetzee studies for two years in Osaka, Tokyo.
Coetzee continued to use the influences of the places and people he had met in Paris and Tokyo in his later works. In 1965 he left Paris, for a small village in Spain. In 1975 he held a solo exhibition that marked the beginning of what some call his ‘protest period’. The day after the opening of the exhibition, he returned to the gallery and cut up 23 of his paintings, and then began to ‘reconstruct’ them. Although the media labelled Coetzee as being angry, he later explained his destructive act in the context of work he had done in the 1950s, calling it a Gutai act. He has become one of South Africa’s most famous artists with exhibitions in South Africa, the USA, Europe, and Japan.
After his death Coetzee donated all his possessions and artworks to the University of Pretoria, which now owns more than 140 of his works.
South Africa marks National Heritage Day on 24 September. To celebrate the diverse heritage of the FABI community, Dr Josephine Queffelec launched the “Picking the Fruits of the Heritage Tree” initiative where FABIans were invited to celebrate their diversity by submitting stories and poems on their connections to plants, pests and pathogens. This also celebrated 2020 as the International Year of Plant Health.
In 2020, the narratives of the 13 participants were as diverse as the origins of the contributors, spanning Chile, Colombia, Ethiopia, France, India, Japan, Namibia, South Africa and Zimbabwe. From trees that connect the dead to the living, insects that are welcomed with ceremony and traditional beer to aphrodisiac “big bottomed ants” and plants to keep in your “herbal first aid box”, FABIans revealed fascinating glimpses to their ancestry, childhoods and the richness of the idioms in their languages and cultures in their creative submissions.

In 2021 Josephine again encouraged FABIans to participate in this project entitled “The Vines of Wisdom” on the second year of this celebration of FABIans’ heritage. (Click here to view the 2021 Project)
Born in Zimbabwe.
Brenda Wingfield is Professor in the Department of Biochemistry, Genetics and Microbiology at the University of Pretoria, and is affiliated with FABI. She commissioned the construction of the work ‘42’ for the FABI 2 foyer.
‘Why 42?’ you might wonder. Brenda explains:
“What do you get if you multiply six by seven? What is the third primary pseudo perfect number? Given 27 same-size cubes whose nominal values progress from 1-27, a 3x3x3 magic cube can be constructed such that every row, column, and corridor, and every diagonal passing through the centre, is composed of three numbers whose sum of values is 42. What is the answer to the Ultimate Question of Life, the Universe, and Everything? What do you get if you multiply 3 by 14?”
