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.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
