Emergence of a Viral Disease Epidemic of Sweet potato in Eastern Africa is Imminent – Plant virologists warn

Published

on

When COVID-19 emerged in 2019, it first remained temporarily localized as an epidemic in Huan China until it broke Chinese national and Asian continental borders attaining a global pandemic status. With COVID-19 and other epidemics and/or pandemics of humans and livestock, it is easier to explain the obvious impact on humans and/or livestock.

What about virus epidemics and pandemics that affect plants?

Virus epidemics and pandemics that affect plants cause significant disruptions in food production. In fact, the emergence and re-emergence of extremely dangerous plant viruses is the major pain to the 21st century agriculture and sustainable food production.

Viral diseases of plants lead to complex outcomes of food shortages, economic meltdown and loss of lives especially when the affected crop plants are central to the economics and livelihoods of the people. Think of what would happen if an epidemic caused significant effect or eliminated crops like maize, banana, cassava or sweetpotato from sub-Saharan Africa.

Most viruses affecting livestock and humans are spread and transmitted by means of physical contact between hosts. Furthermore, human and livestock hosts are mobile. On the other hand, plants do not move and must thus depend on other agents (vectors) for the spread of viruses between hosts. Consequently, over 98% of plant viruses are transmitted by vectors. These vectors may include arthropods (especially insects), nematodes, fungi, and parasitic plants. In plants, a virus disease epidemic becomes optimized by the ability of vectors facilitating fast spread of the virus in an agro-ecosystem.

New study predicts emergence of disease epidemic in sweetpotato

A new study led by Prof. Arthur Tugume at the Department of Plant Sciences, Microbiology and Biotechnology in the College of Natural Sciences at Makerere University predicts potential of emergence of a new disease epidemic in sweetpotato.

The study recognizes that by default, viruses are not constrained to perpetually occupy a single ecological niche. This is because viruses have inherent genetic and evolutionary abilities that enable their acquisition of better fitness to always expand their host and geographical ranges.

While viruses enjoy such fitness advantages in nature, the current study points out unique examples where some viruses in eastern Africa behave awkwardly. These viruses first hid under the guise of being less important and seemingly of no impact in cropping systems, and all of a sudden hell broke loose and the entire farming system was caught unaware.

The study titled; “Endemism and reemergence potential of the ipomovirus Sweetpotato mild mottle virus (family Potyviridae) in Eastern Africa: half a century of mystery” shows that a virus, named Sweetpotato mild mottle virus (SPMMV) was first detected in eastern Africa in the 1970’s. SPMMV is currently the third most prevalent virus of sweepotato in the region and is most destructive in mixed infections with other viruses. Very strangely, SPMMV is geographically restricted to eastern Africa (confirmed only in Uganda, Kenya and Tanzania). This sharply contradicts other known sweetpotato viruses that occur globally wherever sweetpotato is grown.

According to Dr. Deusdedith Mbanzibwa a co-author and Head of Disease Control Unit at Tanzanian Agricultural Research Institute, “it is a half-century-old mystery how SPMMV remains localized in East Africa while other viruses on sweetpotato show a global incidence.” Dr. Mbanzibwa adds, “it is important we generate basic information on this virus as soon as possible such that immediately an epidemic explodes we can counter-it based on the information we have as opposed to being caught unaware of the destructive effects of an epidemic.”

Why should we be concerned about outbreak of an epidemic on sweetpotato?

Plant disease epidemics cause a breakdown in food production and availability in communities that depend on the affected plants as food staples. If sweetpotato production breaks down, it directly translates into limited food supplies in local communities that depend on it for food.

According to Dr. Titus Alicai, a senior virologist and co-author based at the National Crops Resources Research Institute (NaCRRI), Namulonge Uganda, “between the 1980’s-1990’s, a devastating viral pandemic (cassava mosaic disease, CMD) destroyed cassava cropping systems in eastern Africa. As a result, dozens of lives were lost because many communities solely depended on cassava for food and income”. Although these viruses had been detected in the region as early as 1800’s, it was not until the 1980s that destructive effects of the disease became apparent.

Dr. Alicai adds that, “when cassava got destroyed by CMD, sweetpotato became an immediate alternative to millions of hungry people, but now sweetpotato is also burdened with diseases arising from viruses.” Despite heavy investments in disease control in cassava, the CMD pandemic is not completely controlled.

Why is eastern Africa important with respect to emergence of plant viruses?

According to this study, SPMMV is not the first unique virus to emerge or reemerge in eastern Africa. An earlier study by Prof. Tugume and colleagues published in 2010 in Molecular Ecology showed that East Africa is a hotspot for the evolutionary diversification of yet another virus in sweetpotato, named Sweetpotato feathery mottle virus (SPFMV).

Many studies show this region as the home of epidemics in rice caused by Rice yellow mottle virus (RYMV). Highly lethal strains of Cassava mosaic geminiviruses (CMGs) causing CMD initiated this epidemic from eastern Africa. Unique strains of Sweetpotato chlorotic stunt virus (SPCSV) are incident in eastern Africa. SPCSV is unique because it almost indiscriminately enhances the viral concentrations of other co-infecting viruses in sweetpotato. The list of damaging plant viruses or their strains that have emerged from eastern African region is long and cannot not be exhausted here.

Biologists studying diversity of plants and animals have also coded eastern Africa as a home of the “hottest hotspot of biodiversity” of endemic land plants and animals located in Eastern Arc Mountains of Kenya and Tanzania. The features of eastern African ecosystem that incite virus epidemics in plants are not fully known. However, it is suspected that the microclimatic changes as modulated by the Indian Ocean dipole could be one of the drivers of virus emergence and reemergence in the region.

Emergence of SPMMV in sweetpotato closely resemble that of viruses in cassava

The current study specifically compared SPMMV with two viruses infecting cassava: cassava brown streak virus, and Ugandan cassava brown streak virus, collectively called cassava brown streak ipomoviruses (CBSIs).

CBSIs first appeared in the 1930’s in coastal east Africa but went completely silent for about 70 years and then suddenly re-emerged in late 1990’s-mid 2000’s to what is today the single largest threat to cassava production in Africa. CBSIs cause a disease called “cassava brown streak disease” (CBSD). Between 1930’s-1990’s, the CBSIs were able to “amass ability” to cause untold suffering of cassava cropping from 2000’s to-date.

Similarly, since the 1970’s when SPMMV was first reported in the region, the virus has been “amassing an ability” to cause more disease in sweetpotato. This is implied directly by evidence of positive selection found in its genes. Positive selection refers to “survival for the fittest” in Charles Darwin’s terms to mean that, individual virus particles in the SPMMV population are becoming more and more highly efficient in causing disease. Today, half a century later, one can argue that it is about time that the SPMMV will incite a new disease.

Note that both SPMMV and CBSIs belong to the same taxonomic grouping of plant viruses in a genus called “Ipomovirus”, and family called “Potyviridae” which is the largest family of plant viruses with RNA genomes. Hence, similarities in the disease spread between SPMMV and CBSIs are not unexpected.

Expert guide to sweetpotato virology research for preparations against the epidemic

“If we can generate advance basic scientific information concerning how the SPMMV infects sweetpotato plants, how it is transmitted by vectors between plants, and circumstances fostering field spread of the virus, we will be better prepared to handle an epidemic that may arise from the virus,” Prof. Tugume states.

He adds: “we should be able to undertake these studies quickly because SPMMV is naturally incident on sweetpotatoes in Uganda, Kenya and Tanzania in levels causing less damage on its own at the moment, although this damage escalates when the virus occurs in multiple infections.”

The co-authors highlight serious research gaps for critical research investment in sweetpotato virology. Vector transmission is such an important aspect of virus disease epidemics of plants. Therefore, this study has proposed three possible explanations to account for the virus-vector and virus-host relationships of SPMMV. These are called hypothesis #1, #2, and #3, built in a fashion that allows experimentation to prove them right or wrong:

  1. Hypothesis #1:SPMMV is opportunistically aphid-transmitted with potyvirus SPFMV as a helper virus.” This hypothesis postulates that SPMMV is transmitted by “chance” by a group of insects called aphids but this happens when SPMMV co-infects sweetpotatoes with another virus, SPFMV that is transmitted efficiently by aphids.
  2. Hypothesis #2:Vector-mediated transmission of SPMMV is modulated by synergism with SPCSV.” Under this hypothesis, the concentrations of SPMMV in plant tissues increases when it co-infects with another virus, SPCSV, and this increases chances of SPMMV being picked by insects for transmission to other plants.
  3. Hypothesis #3:SPMMV tropism and histo-localization changes upon co-infection with SPCSV.” How much viral concentration is found in different plant tissues can change depending on which tissues that are preferred by the virus. Certain plant viruses prefer to stay and multiply from certain tissues than others.

Dr. Alicai said, “If we can determine vector transmission dynamics including the actual vector(s) transmitting SPMMV, which plant tissues the virus prefers for its multiplication, and generate many complete sequences of SPMMV genomes, we will be better prepared for epidemics arising from the emergence of SPMMV”.

Sweetpotato is a vegetatively propagated plant in which the top-most 15-40cm part of the plant is used for initiating the new crop, a practice that is the main route of accelerated of virus spread in the cropping system. Also, insects especially aphids and whiteflies are the major vectors transmitting viruses in sweetpotato. The research gaps highlighted with respect to SPMMV require urgent attention for advance preparation in case an epidemic breaks loose on the sweetpotato cropping system.

Discussions at the Department of Zoology, Entomology and Fisheries Sciences focused on deepening and broadening a historic collaboration that has shaped aquatic sciences, fisheries research, and environmental management in East Africa for half a century.

A Partnership Rooted in Limnology

The collaboration between Makerere University and BOKU traces its origins to 1975 with the establishment of the International Post-Graduate Course in Limnology (IPGL) by the late Heinz Löffler (1927-2006). The eight-month UNESCO-supported course, hosted in Lunz, Mondsee and Vienna, was designed to train scientists from developing countries in limnology – the study of inland waters.

In 1976, Dr. Gwahaba James Joshua of Makerere’s Department of Zoology, Entomology and Fisheries Sciences became the first beneficiary from the university. Two years later, Boniface Makanga attended the UNESCO course and went on to initiate a Marine Practical Course to the Indian Ocean in 1993. That programme has since grown into over 30 years of annual field activity in Mombasa, benefiting undergraduate and master’s students and strengthening hands-on marine science training at Makerere.

Over time, IPGL evolved into a vibrant International Joint Degree Master’s Programme in Limnology and Wetland Management. The programme has built capacity for 123 aquatic professionals – 56 female and 67 male, including 20 from Makerere University. Notably, 11 dedicated limnologists are currently based within the Department of Zoology, Entomology and Fisheries Sciences, a testament to sustained capacity development.

Expanding into Fisheries, Aquaculture and Regional Networks

The Mak-BOKU collaboration progressively expanded beyond limnology into fisheries, aquaculture, and broader freshwater ecosystem management.

Among the key initiatives was STRECAFISH (2015-2018), which focused on strengthening regional capacity in fisheries and aquaculture research and training to improve food security and livelihoods in Eastern Africa. The programme adopted a modular approach, trained 28 MSc students, supported five full PhDs and 11 MSc research projects, and facilitated 14 staff exchanges.

Simon Mungudit: Mak’s Best Performing Male Science Student & Rising Star in Petroleum Geoscience

Published

on

Simon Mungudit emerged the best performing male science student this year. He is set to graduate from Makerere University, Kampala Uganda, East Africa on 24th February 2026 in the Freedom Square.

At just 24 years old, Simon Mungudit from the College of Natural Sciences (CoNAS) has etched his name in the academic history of Makerere University, having emerged as the overall best male student in the Sciences, an achievement earned through perseverance, discipline, and an unrelenting pursuit of excellence.

Mungudit is set to graduate during 76th graduation ceremony scheduled for 24th to 27th February 2026, having attained a CGPA of 4.76 in the Bachelor of Science in Petroleum Geoscience and Production. His academic interests-Reservoir Engineering, Petrophysics, and Drilling-reflect a deep understanding of the subsurface sciences that power modern energy systems.

Early Life and Journey to Academic Excellence

Born to Mr. Owor Thomas, a Game Ranger with the Uganda Wildlife Authority at Murchison Falls National Park, and Ms. Lilly Obewun Grace of Akuru Bridge Village, Nyaravur Sub-County in Nebbi District, Mungudit’s journey to academic excellence began far from the lecture halls of Makerere. At Karuma Primary School, Mungudit scored 12 aggregates in the Primary Leaving Examinations (PLE), setting the pace for his future success. He proceeded to St. Daniel Comboni College, Nebbi, where he attained 14 aggregates in 8 subjects at O’ Level. He then joined Namilyango College, one of the best secondary schools in Uganda, where he studied Physics, Chemistry, and Mathematics (PCM) and scored 19 points, results that secured him government sponsorship to pursue a Bachelor of Science in Petroleum Geoscience and Production at Makerere University.

Gratitude to his mentors and sponsors

Behind these milestones lies a story of humility, gratitude and opportunity. Mungudit credits his parents for supporting his primary and O’ Level education and expresses gratitude to TotalEnergies, which provided a full bursary for his A’ Level studies, covering tuition, upkeep, and medical care. He also acknowledges the Government of Uganda for sponsoring his university education, a factor he says motivated him to excel.

At Makerere, Mungudit thrived in an environment that blended rigorous academics with mentorship. He pays tribute to his lecturers, particularly Dr. Arthur Batte, Head, Department of Geology and Petroleum Studies, for their unwavering commitment to nurturing students and pushing them to excel.

“I always aimed to excel,” Mungudit says. “Together with a few colleagues, we formed a group and held discussions on a daily. This, coupled with a conducive study environment, prayer, and discipline, enabled us to attain excellent grades.”

Dr Arthur Batte describes Mungidit as a humble yet very intelligent student.

Achievements and Professional Experience

Beyond academics, Mungudit consistently demonstrated expertise in petroleum engineering. In 2024, he led a team that won the Reservoir Modelling Challenge, organized by the American Association of Petroleum Geologists (AAPG) Makerere University Chapter, earning prize money and a sponsored field trip to the Tilenga Project courtesy of COSL. He was First Runner-Up in the Petro Bowl competitions of 2023 and 2025, a highly competitive petroleum knowledge quiz organized by the Society of Petroleum Engineers (SPE) Uganda Section. He served as a Student Officer for the SPE Makerere University Chapter in 2023, and in 2024, he chaired the Organizing Committee of the SPE Annual Students’ Technical Conference and Exhibition, helping bridge the gap between academia and industry.

His learning extended beyond the classroom. During his internship, he worked with TotalEnergies, where he applied petrophysics skills to analyze gas-while-drilling data for formation evaluation, hands-on exposure that sharpened his professional competence. At Makerere University, he mastered PetroMod 2018, a critical software tool in oil and gas exploration. After completing his studies in June 2025, Mungudit trained with the Uganda National Oil Company (UNOC), participating in the 2D seismic acquisition in the Kasurubani Block in Buliisa and Hoima districts.

Mungudit currently works as the Special Projects Coordinator for the Society of Petroleum Engineers (SPE) Uganda Section Student Liaison Committee.

Future Plans

Mungudit hopes to work in the oil and gas industry in the upstream sector as a geoscientist. He also plans to pursue further studies in petroleum engineering.

From a village in Nebbi to the forefront of petroleum geoscience, Mungudit’s story is one of an opportunity seized and potential realized. It is a testament to what is possible when talent meets support, and when determination is guided by faith, mentorship, and service. As Uganda’s oil and gas sector continues to evolve, Mungudit stands as a symbol of the skilled, principled professionals poised to shape its future.

The CoNAS fraternity congratulates Mungudit on this noble achievement.
