The University of the Free State – Next Generation Sequencing (UFS-NGS) Unit hosted a pioneering scholarly engagement initiative for Grade 11 learners from nine secondary schools in Bloemfontein. The three-day event with the theme "Frontiers of Discovery: Illuminating the Impact of Genomics in Science outreach programme” marked the first comprehensive genomics science outreach initiative in the Faculty Health Sciences.

Coordinated by Prof Martin Nyaga, Head of the UFS-NGS Unit, the programme bridged the longstanding gap through practical NGS exposure and ignited a passion for Science, Technology, Engineering, and Mathematics (STEM) by inspiring the next generation of genomic innovators using combined interactive lectures, laboratory demonstrations, career talks, and hands-on workshops. This allowed learners to directly engage with cutting-edge scientific techniques and genomic technologies, especially the scientific and evolutionally impact of Polymerase Chain Reaction (PCR) and NGS.

The initiative engaged selected Grade 11 learners from the nine schools: Brebner, Ikaelelo and Vulamasango (day 1), Atlehang, Castle Bridge School and Kaelang (day 2) and Eunice, Navalsig, and Lekhulong (day 3).

“This outreach programme marks a significant milestone in community-based genomics education in South Africa by offering high school learners the opportunity to engage with modern genomic sciences before making career decisions. The initiative particularly aimed to nurture future scientists and diversify the country’s STEM talent pipeline.

“This historic programme bridged gaps in scientific literacy and diversity in the Free State and concluded each day with a genomics quiz competition, which tested the participant’s newly acquired knowledge/exposure and provided a fun competitive learning opportunity. Six quiz winners across the three days received special prizes, and all students were awarded certificates of participation,” says Prof Nyaga.

 

Hands-on exploration and NHLS virology laboratory tour

The training was held at the UFS-NGS Unit in the School of Biomedical Sciences and at the NHLS Virology laboratories, School of Pathology, Faculty of Health Sciences. Each attending secondary school was represented by five Grade 11 learners and a life science’s educator. Each day, 15 learners and three educators observed hands-on practicals, including DNA extraction, PCR, gel electrophoresis, and DNA library preparation for sequencing on platforms such as Illumina MiSeq and NextSeq 2000.

Guided by the UFS-NGS Unit’s team members; Dr Milton Mogotsi, Hlengiwe Sondlane, Mbali Ncube, Nkosazana Shange, Somila Nazo, Sesiyanda Maseko, Surprise Baloyi, Manyi Eyong and Mamello Maku, the learners were exposed to how DNA is extracted and visualised, how the PCR machine works and how DNA libraries are prepared and sequenced.

Furthermore, a guided laboratory tour of the Virology laboratories at the NHLS was provided by Khauhelo Mafa which offered the leaners the opportunity to observe, diagnostic and molecular workflows in action, resulting in a real-time glimpse into world-class medical research and diagnostics, fuelling curiosity about the role of advanced genomics science in disease control.

 

Inspiration through expert talks

The learners were also inspired by talks from Prof Chris Viljoen, Head of the School of Biomedical Sciences, Prof Zinhle Makatini, Associate Professor and Head of Division of Virology, School of Pathology, and Dr Claudia Ntsapi, Senior Lecturer and researcher in the Department of Basic Medical Sciences at the UFS. Prof Viljoen highlighted the role of science in transforming lives and improving life expectancy, while Prof Makatini gave candid reflections on her professional journey, particularly how she pursued Medical Virology through unwavering determination and excelled to become among the pioneer women specialists in the field in South Africa. Dr Ntsapi inspired the audience with her perseverance from her humble beginnings to earning a PhD in Neurophysiological Sciences against all odds.

The speakers also delivered compelling presentations on the applications of genomics in medicine (e.g.), personalised cancer treatments), public health (e.g.), tracking HIV and COVID-19), agriculture (e.g.), resilient crops), and environmental science (e.g.), ecosystem protection), which resonated well with the learners, educators and the UFS-NGS team. A presentation on diverse career options available at the UFS Faculty of Health Sciences was further provided by Angelique Carson-Porter, a UFS representative from the Department of Nutrition & Dietetics. Her talk on different career pathways in Health Sciences broaden the learners’ horizons, fostering future aspirations.

Dr Emmanuel Ogunbayo, Dr Mogotsi, Thabisa Mpaxa, Nkosazana Shange and Eyong Manyi shared their personal career journey to be at the UFS-NGS Unit, offering advice on academic experiences and opportunities within genomics, bioinformatics, and biotechnology, while answering scholarship queries.

“The career talk opened my eyes. I’m now aiming for a biotechnology degree!” said Neliswa Thwala, a learner from Navalsig CS/S.

Following the enthusiastic response and tangible outcomes of this programme, the UFS-NGS Unit is committed to expanding this initiative, with plans to introduce similar events to other schools and developing sustained mentorship opportunities for learners interested in pursuing genomics-related careers. The UFS-NGS Unit further invites interested partners, sponsors, and stakeholders to collaborate in future outreach and capacity-building programmes to continue bridging the genomics education gap in Africa.

 

Inspire the next generation

Prof. Nyaga’s closing remarks highlighted the learners’ potential to shape the ‘omics’ workforce and stated the intention of the organising committee to expand the mentorship programmes, fostering a vibrant STEM pipeline. “This initiative represents our vision to make genomics accessible and inspire the next generation of African scientists.”

The success of this programme was driven by the UFS-NGS Unit team and was supported by Distribution Platform in Omics (DIPLOMICS).

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
