Pecan inside

A peek inside Jeremy’s latest newsletter is always worthwhile…

An extract from a book usually needs a bit of context if it is to make much sense. Alas, How an Enslaved Gardener Transformed the Pecan Into a Cash Crop lacks a bit of context. It explains how “Antoine’s successful inosculation … ultimately supported the production of up to ten million pounds of pecans annually by the early 1920s, resulting in a multimillion dollar pecan industry,” and that’s good. But the extract alone tells us nothing about the enslaved man Antoine or his enslaver Roman. Still, it isn’t hard to find out more without having to read Beronda L. Montgomery’s book in its entirety, if you wish.

This also gives me an opportunity to remind you about an episode from way back in the mists of time: Pecans and history, in which I spoke to Professor James McWilliams about his book The Pecan: A History of America’s Native Nut. Chapter four is all about Antoine’s graft, though I failed to ask about that.

…see what I did there?

Genebank data at a crossroads

Is genebank data having a moment? Well, it’s a pretty big thing that the botanic gardens community have basically said that they need a Genesys too, and in a hugely co-authored “Perspective” article in Nature Plants to boot. 1

Here we have focused on the living collections data ecosystem, because many aspects to managing these collections are unique within the broader collections sector. But we can look to the more advanced and better-networked accession-level data systems of ex situ agricultural gene banks (for example Genesys), not only for inspiration but with a view to lessons learned, and ultimately as future partners in building an even broader integrated global system for ex situ conservation resources.

Hey, we’re just sitting here waiting for you to decide to join us.

And there’s other stuff going on too. The Australian Virtual Seed Bank Portal has had an update and looks just great, for example. And the Old Vine Registry‘s database has passed 4000 entries. Ok, that covers old vineyards rather than genebank collections, but same difference, don’t @ me. Anyway, would love to see it mashed up with the European Vitis Database one day.

But back to genebanks. People are even building interfaces to their data, to get cool visualizations. And they’re analyzing the data to get a handle on the composition of collections 2, to develop monitoring and evaluation frameworks 3, and to identify gaps and challenges 4. And yes, that includes challenges in data management itself.

Documentation and data management systems required more attention in all genebanks in the study, with no genebank having full passport and inventory data in a searchable data management system, although minimum passport data on 82% of accessions was publicly available in searchable databases, including WIEWS and Genesys. Good quality, well-managed and searchable data on genebank operations are important for accurate and timely decision-making. A common issue was a backlog of data entry, with eight of the genebanks in the study relying to some extent on data retained in paper copy, field books and data sheets. Searching for accession-level data is time-consuming, and paper data sheets may be lost or damaged. Data were also stored in Excel files, making it difficult to query, or genebanks had their own customized data management system that required external support to resolve problems or make improvements. Engels and Ebert (2024) recognized the weak information management systems and online accessibility of accession-level data in national genebanks as a challenge to rationalization, as well as to cost-efficient and effective conservation and use. Despite the increasing use of digital object identifiers for accessions to link accession-level data, the Third Report on the State of the World’s Plant Genetic Resources concluded that progress in the area of documentation has been limited, and training is needed for data managers and genebank managers to adopt available improved data management systems (FAO 2025c).

So, we still have work to do. But imagine what we could achieve if we teamed up with the botanic gardens. And herbaria for that matter.

Agriculture rooted in genebanks, kinda

Diverse Plant Genetic Resources for Food and Agriculture (PGRFA) are an important aspect of biodiversity and greater investment in both in-situ and ex-situ conservation of genetic material will be important. PGRFA are essential for agriculture to adapt to environmental stresses, climate change, and changing markets. In 2022, 5.7 million accessions were reportedly conserved in 831 gene banks by 114 countries including through the International Treaty Benefit Sharing Fund. Continuing to meet funding commitments is critical. Cooperation between informal farmer seed systems and gene banks to maintain genetic material could be scaled up.

Could not have put it better myself. And the fact that it comes from a World Bank report (Agriculture Rooted in Biodiversity) advocating for more sustainable agriculture makes it all the sweeter. Check out p. 71 for the agrobiodiversity section. Then on p. 114 you’ll find a recommendation to: “Support in-situ and conservation of plant and animal genetic material for food and agriculture (PGRFA).” Which is a bit weirdly phrased but makes ex situ conservation a bit more explicit when you look at its components:

  • Develop partnerships between gene banks and community seed funds to exploit the potential of farmer seed systems to maintain genetic material in-situ and share with gene banks (see case studies in Annex 15).
  • Support local seed companies that create markets for locally adapted varieties saved by farmer seed systems (e.g., matching grants to facilitate access to finance for improved seeds facilities.
  • Conduct an inventory of breeds and assess extinction risks.

Frozen 2: This time it’s crop diversity

Speaking of breadfruit… Seeds are the … ahem … bread and butter of traditional genebanks: dry them, chill them, and they’ll keep for decades. But the seeds of many important crops don’t play nice. Some — including breadfruit — are recalcitrant, meaning they die if dried and frozen like well-behaved orthodox seeds. For these species, cryopreservation of the right plant part at really cold temperatures is the way to go. It’s the only realistic way to conserve their diversity safely, cheaply, and long-term. It means not relying on constantly refreshing field or laboratory collections that are vulnerable to pests, disease, climate, or simple human error. It’s a complicated subject technically, but if you need a quick introduction, or indeed a quick revision guide, you could do a lot worse that Dr Bart Panis‘ PowerPoint at the recent CGIAR Annual Genebanks Meeting. It’s 60-odd slides, but you can zip through them in 15 minutes and you’ll have the basics.
