Building capacity in DNA sequencing for agricultural biosciences in Africa

Africa is incredibly rich in plant, animal, and human diversity and uncovering the genetic basis of this diversity could hold the key to improving the productivity of crops and livestock and enhancing human health.

A unique and comprehensive bioinformatics training programme has been launched which aims to help African researchers take advantage of long-read DNA sequencing to unlock the genetic potential of crops and livestock on the continent.

The training titled ‘3rd Generation Genomics and Bioinformatics in Africa’ is jointly organised by the International Livestock Research Institute (ILRI), Kenya, the Earlham Institute with support from UK Research and Innovation (UKRI) Biotechnological and Biological Science Research Council (BBSRC), Oxford Nanopore Technologies and ourselves.

The training is delivered in three phases: ‘Develop’, ‘Demonstrate’ and ‘Deploy’;

  1. The ‘Develop’ phase is a two-month long hybrid (residential and online) training programme that introduces all the major steps in long-read sequencing from DNA extraction, library preparation, sequencing, and bioinformatics analyses

  2. The ‘Demonstrate’ phase allows for project-based learning where trainees get hands-on experience from three short projects

  3. The ‘Deploy’ phase will extend the impact of the training to the home institutions of the trainees across the continent. In this phase, the trainees implement a long-read sequencing project they design themselves and will also train others in their home institutions

Professor Cristobal Uauy commented on the training: “We believe that the widespread adoption of modern sequencing technologies in Africa could unleash the unrealised genetic potential for increased productivity in food crops and livestock in order to achieve UN Sustainable Development Goals. Our training is empowering African researchers to be the driving force behind this rapid acceleration of agricultural productivity gains in Africa”.

Using technology from Oxford Nanopore, it’s possible to sequence DNA of any length, which makes it easier to analyse the genomes of crops, livestock and pathogens, and is particularly useful for uncovering large variations that conventional short read sequencing platforms are blind to.

Oxford Nanopore also offers unprecedented access to sequencing in Africa due to its low acquisition costs and easy portability – the MinION sequencer is a palm-sized device that can be setup in any laboratory.

Associate Director Market Development at Oxford Nanopore, Iain MacLaren-Lee, commented on the training: ‘We are delighted to support this programme, which gives the training fellows an opportunity to advance their own research using nanopore sequencing. We hope they will go on to become leaders that will enable many more African scientists to benefit from such genomics insights”.

15 early-career researchers – seven women and eight men – from nine African countries have benefited from the residential training, with over 200 other African researchers participating online.

Sumaya Kambal, one of the training fellows commented: ‘Participating in the training has been a valuable experience in my pursuit of becoming a skilled researcher in bioinformatics and agricultural bioscience. I have gained experience in designing genomics experiments, thinking critically and dealing with challenges related to both laboratory and bioinformatics work. With the skills acquired and the networks built, I look forward to developing a bioinformatics training capacity at my home institution”.

The training also builds on the first Bioinformatics Community of Practice (BixCoP) training, which started in 2018.

Dr Rob Davey from the Earlham Institute, said: “It was fantastic to be able to return to deliver training and to see previous BiXCoP fellows become trainers. This is a vital component of our strategy – building capacity in-country through in-depth and focused technical training in key areas of real-world informatics”.

Jean-Baka Domelevo Entfellner from ILRI also commented: “At ILRI, we firmly believe that the African continent must develop its own capacity in terms of researchers skilled in genomics and bioinformatics. We are very proud of empowering these African scientists with the mastery of cutting-edge tools in long reads sequencing and in bioinformatics analysis. We believe they will make a mark in their respective fields of study and will pass on their knowledge to dozens of their colleagues all across the continent”.
