- Towards a practical threat assessment methodology for crop landraces. Basically red listing for landraces.
- Preserving traditional systems: Identification of agricultural heritage areas based on agro-biodiversity. First places to apply the above?
- Genetic erosion within the Fabada dry bean market class revealed by high-throughput genotyping. Would have been nice to apply the above before doing this study.
- Restoration of the traditional high-altitude rice variety Dumbja in Bhutan. Highlights one of the problems with monitoring threats to landraces, i.e. how to define the landrace.
- Identifying genetically redundant accessions in the world’s largest cassava collection. About half of over 5000 genebank accessions were unique. Easier to recognize cassava landraces I guess.
- Agricultural commercialisation among women smallholder farmers in Nigeria: Implication for food security. Will commercialization help preserve some landraces but threaten others?
- The groundnut improvement network for Africa (GINA) germplasm collection: a unique genetic resource for breeding and gene discovery. Over a thousand accessions that will be just fine.
- An Appropriate Genetic Approach to Endangered Podolian Grey Cattle in the Context of Preserving Biodiversity and Sustainable Conservation of Genetic Resources. The livestock people monitor threat to breeds all the time, it seems.

- The economic impact of CGIAR-related crop technologies on agricultural productivity in developing countries, 1961–2020. In 2020, modern varieties bred by CGIAR or developed by other institutions using CGIAR germplasm were sown on about 190 M ha, about 26% of the total harvested area of these crops in developing countries, and 43% of the total area sown with modern varieties for these crops in developing countries. Yes, cool, but…
- Farming practices to enhance biodiversity across biomes: a systematic review. Less intensive practices generally enhance biodiversity.
- Effects of landscape simplicity on crop yield: A reanalysis of a global database. Simplifying landscapes is associated with lower rates of pollination, pest control and other ecosystem services, and lower crop yields.
- Biocultural diversity and crop improvement. Crop improvement can enhance crop diversity, but doesn’t always.
- Collaboration between Private and Public Genebanks in Conserving and Using Plant Genetic Resources. Vegetable breeding companies can contribute to the conservation of crop diversity by public genebanks, but it takes work on both sides.
- Eight arguments why biodiversity is important to safeguard food security. It’s not “stop hunger first, then worry about diversity afterward”. Or it shouldn’t be.
- Landrace legislation in the world: status and perspectives with emphasis in EU system. Policy can support the conservation and use of landraces. Or not. It’s a choice.
- Convention on Biological Diversity (CBD) and the Nagoya Protocol: Implications and Compliance Strategies for the Global Coffee Community. Maybe they should consider the Plant Treaty approach?
- The global distribution of plants used by humans. 35,687 of them, and their richness is negatively correlated with protected areas.
Nibbles: Cheese microbes, OSSI, Mung bean, Sustainable ag, Agroecology, Collard greens, African orphan crops, Olive diversity, Mezcal threats, German perry, Spanish tomatoes, N fixation
- A sustainable blue cheese industry needs more microbial diversity.
- The Open Source Seed Initiative gets written up in The Guardian. Looks like we need something similar for cheese microbes.
- The Guardian then follows up with mung bean breeding and fart jokes.
- But then goes all serious with talk of trillions of dollars in benefits from sustainable food systems. Diversity not mentioned, alas, though, so one wonders about the point of the previous pieces.
- Fortunately Indigeneous Colombian farmers have the right idea about sustainability.
- Collard greens breeders do too, for that matter.
- More African native crops hype for Dr Wood to object to. Seriously though, some crops do need more research, if only so they can be grown somewhere else.
- There’s plenty of research — and art for that matter — on the olive, but the international genebanks could do with more recognition.
- The mezcal agave, on the other hand, doesn’t seem to have much diversity in genebanks, and it is threatened in the wild.
- Perry culture in Germany is also threatened. Pretty sure there are genebanks though.
- This piece about tomato diversity in Spain is worth reading for many reasons (heroic seed saving yada yada), but especially for the deadpan take on the Guardia Civil at the end.
- Maybe we could breed some of those tomatoes to fix their own nitrogen. And get the Guardia Civil to pay for it.
Brainfood: Breeding edition
- Climate-resilient crops: Lessons from xerophytes. Breeding for Na+ exclusion to improve salinity tolerance in crops has compromised their drought tolerance, but both tolerances are down to more gene copies in key families when comparing species.
- Innovation and Technological Mismatch: Experimental Evidence from Improved Crop Seeds. Breeders should strive to give farmers what they want, even if it means releasing multiple locally adapted varieties rather than a single blockbuster.
- Stressors and Resilience within the Cassava Value Chain in Nigeria: Preferred Cassava Variety Traits and Response Strategies of Men and Women to Inform Breeding. Man and women want different things from cassava breeders.
- Intra-household discrete choice experiment for trait preferences: a new method. If only there was a new way to measure that…
- Genome editing to re-domesticate and accelerate use of barley crop wild relatives. No word on whether men and women would edit different genes.
- Understanding Genome Structure Facilitates the Use of Wild Lentil Germplasm for Breeding: A Case Study with Shattering Loci. I suspect neither men nor women would tolerate shattering lentils.
- Repeat turnover meets stable chromosomes: repetitive DNA sequences mark speciation and gene pool boundaries in sugar beet and wild beets. But you can’t use wild species in breeding if you can’t cross them with the crop, and in beet that’s down to the repeatome. So maybe this would make a better case for domestication through gene editing than barley or lentils?
- Development of trait-specific genetic stocks derived from wild Cicer species as novel sources of resistance to important diseases for chickpea improvement. Would be really cool to domesticate one of the really resistant tertiary genepool species.
- Developing Genetic Resources Within the Chenopodium Genus to Advance Quinoa Breeding and the de novo Domestication of C. berlandieri. Not that you need gene editing for domesticating crop wild relatives.
- Genomic traces of Japanese malting barley breeding in two modern high-quality cultivars, ‘Sukai Golden’ and ‘Sachiho Golden’. Old-fashioned breeding has been pretty successful, so who needs CWR, gene editing and discrete choice experiments? ((Last bit added purely for clicks, I’m desperate.))
- Consistent effects of independent domestication events on the plant microbiota. I hope all those gene-editing de novo domesticators are considering the novo microbiomes.
Brainfood: Nutrition edition
- Which crop biodiversity is used by the food industry throughout the world? A first evidence for legume species. Mainly soy, alas. Which is bad because…
- Diversified agriculture leads to diversified diets: panel data evidence from Bangladesh. …promoting diversified farming systems and market participation is good for women’s empowerment and better diets. Which is just as well because…
- Historical shifting in grain mineral density of landmark rice and wheat cultivars released over the past 50 years in India. …breeding hasn’t been good for nutritional content in staples.
- Surviving mutations: how an Indonesian Capsicum frutescens L. cultivar maintains capsaicin biosynthesis despite disruptive mutations. But if you can breed for extreme pungency, you can surely breed for better nutrient content.
- Exploiting Indian landraces to develop biofortified grain sorghum with high protein and minerals. Yep, simple selection can make a sorghum landrace more nutritious.
- Genome-edited foods. Or you could resort to gene editing.
- Adoption and impact of improved amaranth cultivars in Tanzania using DNA fingerprinting. Although maybe it might be easier to just eat more amaranth.
- Stakeholders’ perceptions of and preferences for utilizing fonio (Digitaria exilis) to enrich local diets for food and nutritional security in Nigeria. But documenting knowledge will be key in either case.
- Domestication through clandestine cultivation constrained genetic diversity in magic mushrooms relative to naturalized populations. And watch what you’re doing to diversity.
