- Status and future of seed conservation of threatened plants in the post-2020 era. 21% of threatened plants are conserved in genebanks across 44 countries in Europe and western Asia. Not bad, but not good enough. I wonder how many of those 21% will be of interest to breeders?
- How the international treaty on plant genetic resources for food and agriculture can support effective germplasm exchange: four Colombian case studies. The Plant Treaty can really help a country’s genebanks and breeders drive agricultural development, given half a chance.
- Reconciliation or re-colonization? Critical perspectives on seed banking and colonialism. Indigenous communities need to be careful in collaborating with genebanks and breeders.
- Impacts of climate change on fonio millet: seed germination ecology and suitability modelling of an indigenous West African cereal. Climate change will screw up the germination of fonio in some places, so genebanks and breeders better get cracking.
- Euterpe edulis seed recalcitrance: difficult, yes, but not impossible to genebank. Tricky seed storage behaviour need not deter genebankers.
- Accelerated aging caused diversity and specificity loss in the bacterial communities of Brassica napus seedlings. Genebanks should be careful with their seed aging experiments, because they might screw up the seed microbiome.
- Understanding Biotic Constraints to Taro (Colocasia esculenta) Production in the Derived Savanna and Humid Forest Agroecosystems of Nigeria. Genebanks need seed systems though.
Brainfood: Clonal crops edition
- Ancient DNA reveals 4000 years of grapevine diversity, viticulture and clonal propagation in France. Vegetative propagation of grapevines has been going on since the Iron Age.
- High-throughput olive germplasm classification using morphological phenotyping and machine learning. Olive may be generally vegetatively propagated, but you still have to characterize the fruits.
- Varietal Diversity Analysis of Date Palm and Identification of High Agro-Economic Genotypes in Middle Draa. About half of of the date palms in the middle Draa of Morocco are actually from seed. That makes their diversity difficult to conserve.
- Genebank tools for efficient management of viral infections in tropical clonal crops. All those clonal crops need to be kept clean in genebanks. Here’s how.
- Genome degradation in plant tissue culture. All those clonal crops also need to be kept genetically stable in genebanks, and it can be tricky.
Brainfood: Restoration edition
- Addressing critiques refines global estimates of reforestation potential for climate change mitigation. Better mapping shows there is less land available for reforestation than we thought, and there are limited opportunities for providing multiple benefits. Still, that’s an area the size of Mexico, and worth trying to get it right.
- Genomic approaches to accelerate American chestnut restoration. The American chestnut people seem to be getting it right.
- A native seed bank is restoring land in Canada’s north. Native people — and their genebanks — can help you get it right.
- Controlled Pollination and Reproductive Strategies in Coconut: A Framework for Farmer-Led Breeding, Seednut Production, and In Situ Conservation. Farmers can be helped to get it right.
- Dehulling the secret of the germination of crop wild relatives of Cenchrus, Digitaria, Echinochloa, Setaria and Urochloa. You need information on germination breaking to get it right. In the US Midwest, for example.
- How can Brazilian legislation on native seeds advance based on good practices of restoration in other countries? Not to mention the right policies.
Brainfood: Genebanks edition
- Seed collection and processing practices affect subsequent seed storage longevity in durum wheat and wild relatives. Immature seeds can still usefully be harvested for long-term storage of properly handled.
- Two-step drying of soya bean seed germplasm often improves subsequent storage longevity. “Proper handling” includes drying at higher temperatures.
- Seed-stored transcript integrity as a molecular indicator of viability in conserved common bean germplasm. mRNA degradation predicts loss of seed viability.
- Developing a cryopreservation protocol for the conservation of coconut palm (Cocos nucifera L.) using a novel type of explant, meristematic clumps. Who needs seeds anyway?
- Pollen cryobanking at the USDA-ARS National Laboratory for Genetic Resources Preservation. Well, who needs meristematic clumps?
- Mapping pea seed composition through strategic selection of accessions from the Nordic gene bank. Image analysis can be used to maximise diversity in nutritional composition in pea seeds, thus facilitating use of genebank collections. Can’t do that with pollen, I suspect.
- A small-scale assessment of the availability of EURISCO accessions. Facilitating use needs all the help it can get.
- Strengthening national genebanks through genomics and regional collaboration: Lessons from Latin America and the Caribbean. I guess genomics capacity could help with use.
- Enhancing farmers’ access and use of conserved germplasm for improved food security and climate resilience: The case of sorghum at Kenya’s national genebank. Genomics unavailable for comment. Farmers, on the other hand….
- Linking the ICRISAT Genebank to Poverty Reduction and Welfare in Malawi. Facilitating use by farmers is important.
- Farmers as breeders and seed producers: Insights from 30 years of scaling up seed clubs in Vietnam. It’s super cool when farmers organize. Including for genebanks.
- Elephant ear yam Xanthosoma robustum Schott (Araceae), a neglected crop native to Central America. Needs more attention from genebanks. And farmers and their clubs for that matter.
- Plant genebank of Sudan: Towards recovery from the wreckage of war to a new era of further capacity development based on lessons learnt from similar situations. We must de-risk genebanks. Wouldn’t want to lose all those elephant ear yam collections we’ll be making.
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.
