Prof Rodney Moffett, Honorary Research Fellow in the Department of Plant Sciences at the University of the Free State (UFS) and Top Research Fellow in the Afromontane Research Unit (2018-2019) on the UFS Qwaqwa Campus, was recently awarded a Silver Medal from the South African Association of Botanists (SAAB) at their 48th annual conference that took place in Polokwane.

Prof Sandy-Lynn Steenhuisen, Subject Head and Associate Professor in the Department of Plant Sciences on the UFS Qwaqwa Campus, says, “It was an absolute joy and honour to be able to nominate and present a SAAB Silver Medal to Prof Moffett, who is an iconic figure and friend in our department. I was so happy that he could receive his award in person, with his daughter visiting from the United Kingdom. He inspires my research group so much with his knowledge of plants of the Eastern Free State and through the wealth of specimens he’s contributed to the QWA herbarium.”

The conference with the theme, ‘Plants, Health and Prosperity’, was hosted by the University of Limpopo’s Faculty of Science and Agriculture under the School of Molecular and Life Sciences in the Department of Biodiversity.

Outstanding research contributions 

According to Prof Steenhuisen, Prof Moffett received the Silver Medal Award for his outstanding research that contributed to the advancement of botany and plant sciences in South Africa.

Since his retirement, Prof Moffett has published a number of book chapters, books, reports, and articles on various aspects of fauna and flora. 

He sole-authored eight books and authored/co-authored more than 36 peer-reviewed articles in scientific journals covering mainly the taxonomy of plant genera such as Sarcocaulon, Rhus, and Searsia, and checklists of vascular plants and their medicinal uses for the Qwaqwa and Lesotho regions. 

Around 2006, Prof Moffett pursued his passion to document and describe the ethnobotanical uses of plants used by the Basotho people of Lesotho and South Africa. His books focused, for instance, on the natural history and Sesotho names of the plants used by the Basotho of the Eastern Free State and their ethnobotanical uses, the taxonomic works on the grasses of the Eastern Free State (still the most detailed grass identification guide for the area to date), and the flora and fauna of the Clarens Village Conservancy (a field guide). 

Prof Moffett has also published a scientific bibliography of the Drakensberg, Malotis and adjacent lowlands, which Prof Steenhuisen describes as “a mammoth task and one which he is continually updating and expanding, with another volume in preparation”.

Prof Steenhuisen, who nominated Prof Moffett for the Silver Medal Award, says that as a highly respected naturalist in the Qwaqwa region, he is continually consulted by conservation authorities, researchers, and postgraduate students on the flora of the area. He also regularly presents his research at garden and botanical societies. 

Among the books he has published are Sesotho names of plants and animals and plants used by the Basotho (2010), A biographical dictionary of contributors to the natural history of the Free State and Lesotho (2014), and Meriana ya dimela tsa Basotho – Basotho medicinal plants (2016 and 2020). In 2020, he also published A Scientific Bibliography of the Drakensberg, Maloti and adjacent Lowlands.

Prof Steenhuisen states that Prof Moffett’s books are treasured resources for anyone working in the Maloti-Drakensberg area. 

Best poster presentation

Joining researchers, postgraduate students, and experts from other universities and organisations at the conference, was the Plant Ecology Research Group of Prof Steenhuisen, her postgraduate students, and a postdoctoral fellow involved in invasive species and climate change research. Postgraduates from three other research groups (Plant Biotechnology, Proteomics, and Ethnobotany supervised by Dr Arun Gokul, Dr Rudo Ngara, and Prof Anofi Ashafa) on the Qwaqwa Campus also attended the conference. 

Dr Makoena Moloi, Senior Lecturer in the Department of Plant Sciences on the Bloemfontein Campus, and her postgraduate students researching aspects of plant ecophysiology, were also present at the conference, together with master’s candidate Orateng Sedimo, who is supervised by Dr Lize Joubert, Senior Lecturer in the department. Sedimo presented his honours research and won a prize for presenting the best Honours poster in the category Molecular Systematics. 

Besides being well-represented at the 48th SAAB annual conference and being awarded for its outstanding contributions to botany and plant sciences, academics from the UFS had the opportunity to learn from and network with some of the best scientists in the field. This included A1-rated scientist, Prof Steven Johnson from the University of KwaZulu-Natal, (Prof Steenhuisen’s supervisor for her PhD), and B2-rated Prof Anton Pauw from Stellenbosch University. Prof Johnson and Prof Pauw were respectively awarded a Gold and second Silver Medal from SAAB.

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
