Abstract: Abstract Genebanking, the process of preserving genetic resources, is a central practice in the modern management of crop genetics, especially for the species used for food and agriculture. Closely interrelated networks of local, national and global actors are responsible for ex situ conservation. They all seek to make plant genetic resources accessible for all and now face new challenges arising from digitisation. Plant sciences are entering the postgenomic era, moving fast from initially providing a single reference genome for each species (genomics), to harnessing the extent of diversity within crop species (pangenomics) and among their relatives (referred to as postgenomics). This paper describes the extent to which ex situ collections have already undergone a digital shift, or are planning to do so, and the potential impact of this postgenomic-induced dematerialisation on the global governance of plant genetic resources. In turn, digitising material (seed) collection changes the relationship between genebanks and genomic databases. Comprehensive genomic characterisation of genebank accessions is ongoing, and I argue here that these efforts may provide a unique opportunity for genebanks to further embrace the moral, ethical and ultimately political principles on which they were built. Repurposing genebanks as decentralised digital biocentres could help relocate capabilities and stewardship over genetic resources. Empowering local farmers by providing access, promoting the use and unlocking benefits from state-of-the-art tools of modern plant breeding may allow bridging the breeding divide. However, to accomplish such a paradigm shift, genebanks require a strong political mandate that must primarily originate from the access and benefit-sharing framework. Only so may the global challenges associated with the loss of biodiversity and food insecurity be addressed.
