Prince Matova, a PhD student in the Department of Plant Sciences, has been working on breeding a maize that can resist the fall armyworm (FAW) – a maize-eating pest. Later in September, he will receive the Young Scientist Award from the Plant Mutation Breeding Division of the International Atomic Energy Agency (IAEA) and the Food and Agriculture Organisation of the United Nations (FAO).

Prince Matova, a PhD student in Plant Breeding at the University of the Free State (UFS), received the Young Scientist Award from the Joint Food and Agriculture Organisation of the United Nations (FAO)/International Atomic Energy Agency (IAEA) Division of Nuclear Techniques in Food and Agriculture for excellence in plant mutation breeding.

The IAEA Director-General, Mr Rafael Mariano Grossi, will officially announce the award at the 65th regular session of the IAEA General Conference that will take place later in September this year.

The award is given to scientists younger than 40, who have made a significant contribution and impact in the field of mutation breeding.

Matova, a researcher, research and agronomy manager, and maize and legumes breeder at Mukushi Seeds (Pvt) Ltd in Harare, Zimbabwe, says: “People have seen the little work that I have done, and they were happy with it. That makes me happy too.”

Other contributions

In the ten years collaborating with the IAEA, practising mutation breeding, Matova – who believes innovative thinking and self-motivation to be contributing factors to a successful scientist – has also been recognised for other outstanding contributions. These include the release of a cowpea mutant variety in 2017 and its wide dissemination across Zimbabwe, as well as the modernisation of the maize and cowpea national breeding programmes. He has also contributed two publications and appeared twice at IAEA Plant Mutation Breeding symposia. Furthermore, Matova has trained other scientists and fellows across Africa and collaborated with centres of excellence in plant breeding, research, and development.

Growing up, he never guessed that he would one day become an agricultural scientist. Matova was, however, very good at biology and believes that this is one of the reasons why he ended up in crop science. “I am enjoying every moment of it. I love innovativeness and inventions and I view hybrid maize variety development as the greatest innovation in plant breeding. Working for Mukushi Seeds is inspiring; I have a young and dedicated team and the environment allows me to explore my full potential.”

“I feel science solves problems and every day as I do my breeding work, I have this desire to achieve greatness by developing a super maize hybrid,” he says.

Displaying excellence

For the past three to four years, Matova has been working to breed maize varieties that can resist fall armyworm (FAW) – a maize-eating pest. He says the pest has caused significant maize crop yield and economic losses across Africa.

More than 300 million smallholder farmers across sub-Saharan Africa rely on maize for food and livelihoods. “These farmers have limited capacities to control the pest. They are using insecticides, which we have seen to effectively provide immediate control of the pest.” However, these pesticides have environmental and health issues. “It is against this background that we, as plant breeders, felt it was important to develop varieties that are resistant to the pest. It is a more environmentally friendly, less expensive, and more sustainable solution,” explains Matova.
In his research, he evaluated the breeding potential of exotic FAW-resistant donor lines with local lines. He also investigated the resistance response and stability of local cultivars and inbred lines against FAW. 

While working at the Zimbabwean Department of Research and Specialist Services (DR&SS), Matova collaborated with the International Maize and Wheat Improvement Center (CIMMYT), the University of Zimbabwe, the UFS, and the IAEA to look into the possibility of using mutation breeding in maize crop improvement, with the intention to enhance FAW-resistance in maize genotypes.

He introgressed FAW resistance into the elite breeding materials at both DR&SS and Mukushi Seeds, where he is currently working. Matova believes that although FAW resistance is currently a nice-to-have trait, going forward, all maize varieties released should have a baseline resistance to FAW.

Ultimately, his work generated important information that can guide research and maize breeding for FAW resistance in Southern Africa. All this information is free for researchers to use for the betterment of Africa and the world.

Inspired by greatness

There are a number of people in the industry and academia who have inspired Matova. The list includes Dr Cosmos Magorokosho (CIMMYT), Prof Hussein Shimelis (University of KwaZulu-Natal), Dr Fatma Sarsu (IAEA), Dr Marilyn Warburton (Agricultural Research Service in the United States Department of Agriculture), Dr Amsal Terekegne (ZAMSEED), and Dr John MacRobert (Mukushi Seeds). They all contributed in one way or another to influence Matova in a positive way towards becoming the passionate scientist he is today.

Besides this list of prominent names, Matova says that he was more recently also motivated and encouraged by his PhD supervisor and mentor, Prof Maryke Labuschagne, Professor in Plant Sciences at the UFS. “She is a very special person doing a wonderful job. Prof Labuschagne is kind, thorough, hardworking, and a good mentor,” he states.

Prof Labuschagne is very proud of Matova for receiving this award. “He has been working really hard, and this is a wonderful recognition of the time and effort that he has invested in his research,” she says.

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.
