Prof Maryke Labuschagne is a Professor of Plant Breeding in the UFS Department of Plant Sciences.

A new research chair at the University of the Free State (UFS), led by Prof Maryke Labuschagne, a Professor of Plant Breeding in the UFS Department of Plant Sciences, hopes to increase food and nutritional security in South Africa through crops that have intrinsic high nutritional value.

The Breeding Climate-Resilient Vegetables and Grains research chair was established in partnership with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD). It will be hosted within the Faculty of Natural and Agricultural Sciences (NAS) alongside the other ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production. 

The aim of the new ARC-DALLRD-UFS research chair, explains Prof Labuschagne, who is also leading the National Research Foundation (NRF) SARChI Chair in Diseases and Quality of Field Crops, is to breed climate resilient crops with high levels of nutrients such as iron, zinc, provitamin A and essential amino acids, as well as disease resistance, in collaboration with the ARC.

Breeding of climate resilient crops

“We are all aware of the need for food security in South Africa. Climate change is already negatively impacting food production. With this research chair, in collaboration with the ARC, we hope to increase food security through crops that have intrinsic high nutritional value, for example, high levels of iron and zinc and provitamin A, of which there are high levels of deficiency in our population, and at the same time increase climate resilience (such as heat and drought tolerance) in these crops.

“We will be working on breeding climate-resilient, nutrient-rich and disease-resistant pigeon pea and cowpea cultivars; maize rich in provitamin A, iron and zinc; highly nutritious sweet and bitter sorghum; rust-resistant and good-quality wheat; high-yielding and nutritious indigenous vegetables such as amaranth and amadumbi; and research on potato, sweet potato and cassava for human and industrial uses,” says Prof Labuschagne.

The new chair will complement the research that is already being done for the SARChI chair, but with the ARC as partner. It will combine the expertise and resources of Plant Breeding at the UFS with that of the ARC-VIMP (Vegetable, Industrial and Medicinal Plants), ARC-GC (Grain Crops) and ARC-SC (Small Grains). The chair research will include orphan crops such as cowpea, pigeon pea and indigenous vegetables, as well as root and tuber crops such as potato and cassava, and cereals such as wheat, maize and sorghum.

Collaborative research

“The focus of this chair is on collaborative research and student training with the ARC, but the research area will still focus on the development of nutrient-rich and disease-resistant food-security crops. It will also have an additional focus of climate resilience, and the inclusion of orphan crops indigenous to Africa and South Africa.”

Prof Labuschagne says it is exciting that collaborative research can now be done with the unique expertise and resources (laboratory equipment, fields, greenhouses etc.) of several research institutes for the benefit of food and nutritional security in South Africa. Doing this research in a large team with lots of expertise in different areas will certainly yield more and better results with a larger impact on food security.

“This is a very exciting development in agricultural research now that we are part of a large team all working towards the same goal of improving food security, sharing expertise and resources and also doing collaborative training of MSc and PhD students who will become the scientists of tomorrow, taking this quest into the future.”

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says this chair is aligned to the UFS Vision 130 strategy, shaped by excellence and impact, sustainability and society. “This distinguished chair led by Prof Labuschagne recognises exceptional achievement and pre-eminence in the field to catalyse and ignite new talent and new knowledge. It marks an exciting opportunity to deepen our understanding of breeding climate-resilient vegetables and grains aligned to our expertise in agriculture.”

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
