Beyond a reference genome: pangenomes and population genomics of underutilized and orphan crops for future food and nutrition security

Abstract: Underutilized crops are, by definition, under-researched compared to staple crops yet come with traits that may be especially important given climate change and the need to feed a globally increasing population. These crops are often stress-tolerant, and this combined with unique and beneficial nutritional profiles. Whilst progress is being made by generating reference genome sequences, in this Tansley Review, we show how this is only the very first step. We advocate that going 'beyond a reference genome' shou… Show more

“…In 2020, at least 720million people (≥ 9.9% of the global population) will face hunger; It is the largest percentage of the total population since 2010 ( FAO, IFAD, UNICEF, WFP, and WHO, 2021 ). In order to alleviate global hunger, more attention needs to be paid to non-staple food crops ( Chapman et al, 2022 ). Chestnut, as a tree species that has been used to fight against hunger in history ( Gabriele et al, 2020 ), should be paid more attention and studied.…”

“…Because of the ongoing climate change as well as the increasing global population and the COVID19 pandemic, the number of people facing hunger is expected to rise significantly. To alleviate global hunger, more attention needs to be given to non-staple food crops ( Chapman et al, 2022 ). Historically, chestnuts was promoted to fight hunger ( Gabriele et al, 2020 ).…”

“…Hybrid breeding had obvious advantages and positive side effects in rye. In contrast to many valuable crops with a relatively small acreage that became orphans for which breeding was no longer carried out [ 156 ], hybrid rye, as with quinoa, chickpea and pigeonpea [ 157 ], serves as a further example of orphan crops with obvious potential for reducing the dependence of the world food system on a limited number of crops. The benefits of hybrid rye to farmers are increased yield potential, and strong lodging resistance in semidwarf rye.…”

“…Genome-assisted breeding offers hope of a new green revolution by helping to uncover and unlock novel genetic variation for crop improvement. Over the last 20 years, the genomes of 135 domesticated crops have been sequenced and assembled 3 , including those of orphan crops 2 . However, it has recently been acknowledged that researchers from Africa are grossly under-representated in the genome sequencing efforts of their indigenous orphan crops 3,4 .…”

“…This over-dependence on a few staple crops increases the vulnerability of global food systems to environmental and social instabilities. One promising strategy to diversify food systems is to improve the productivity and adoption of climate-resilient but underutilised orphan crops through genome-assisted breeding 2 .…”
