- Benefit–Cost Analysis of Increased Funding for Agricultural Research and Development in the Global South. Fancy model says funding agricultural research is great value for money. Ok, let’s see if we can find some examples.
- Exploring CGIAR’s efforts towards achieving the Paris Agreement’s climate-change targets. Yeah, but in designing such research to mitigate climate change there should be more complete integration of food-systems perspectives.
- Crop species diversity: A key strategy for sustainable food system transformation and climate resilience. Now there’s a nice thing to integrate into your climate change adaptation and integration research.
- Cultivating success: Bridging the gaps in plant breeding training in Australia, Canada, and New Zealand. Gonna need more plant breeders also, though.
- Artificial intelligence in plant breeding. Yeah, and probably more artificial intelligence too.
- Wheat genetic resources have avoided disease pandemics, improved food security, and reduced environmental footprints: A review of historical impacts and future opportunities. Great advances have been made (even without AI) by wheat breeders, but there’s still a lot of untapped diversity out there.
- Harnessing landrace diversity empowers wheat breeding. For example in the A. E. Watkins landrace collection.
- Enhanced radiation use efficiency and grain filling rate as the main drivers of grain yield genetic gains in the CIMMYT elite spring wheat yield trial. Gotta wonder if there’s a limit though.
- Origin and evolution of the bread wheat D genome. Maybe we can squeeze a bit more out of the D genome. I wonder what AI says about that.
- The Role of Crop Wild Relatives and Landraces of Forage Legumes in Pre-Breeding as a Response to Climate Change. As above, but for a bunch of forages.
- Stakeholder Insights: A Socio-Agronomic Study on Varietal Innovation Adoption, Preferences, and Sustainability in the Arracacha Crop (Arracacia xanthorrhiza B.). Here’s an interesting methodology to evaluate the impact of new varieties designed and developed by AI (or not).
- Deep genotyping reveals specific adaptation footprints of conventional and organic farming in barley populations — an evolutionary plant breeding approach. An initial, diverse barley population is allowed to adapt to contrasting organic and conventional conditions for 2 decades and diverges considerably genetically as a result. Don’t need AI to predict that. Perhaps more surprisingly, analysis suggests organic-adapted populations need to be selected for root traits to catch up in yield.
- Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley. What is it with barley breeding and long-term experiments? This one shows that a hundred years of natural selection has massively narrowed genetic diversity. Why aren’t there long-term wheat experiments? Or are there?
- Association study of crude seed protein and fat concentration in a USDA pea diversity panel. Really high protein peas are possible. No word on whether kids will like them any better. Let’s check again in a hundred years?
- Telomere-to-telomere Citrullus super-pangenome provides direction for watermelon breeding. Forget sweetness and disease resistance, maybe one of these wild species will help us grasp the holy grail of seedlessness. Wait, let me check on the whole cost-benefit thing for this.
- An indigenous germplasm of Brassica rapa var. yellow NRCPB rapa 8 enhanced resynthesis of Brassica juncea without in vitro intervention. Sort of like that wheat D genome thing, but for mustard. I do wonder why we don’t try crop re-synthesis a lot more.
- Special issue: Tropical roots, tubers and bananas: New breeding tools and methods to meet consumer preferences. Why involving farmers in all of the above could be a good idea.
Brainfood: Yield gap, Domestication & breeding, TEK, Breeding gourds, Breeding pearl millet, Breeding peas, Banana seed systems, Breeding bees
- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.
- Editorial: Current status of honey bee genetic and breeding programs: progress and perspectives. Pollinators need breeding programmes too.
Brainfood: Archaeology edition
- Early human selection of crops’ wild progenitors explains the acquisitive physiology of modern cultivars. The high leaf nitrogen, photosynthesis, conductance and transpiration of crops was already there in their wild relatives, the first farmers just happened to domesticate greedy plants.
- The impact of farming on prehistoric culinary practices throughout Northern Europe. When the first farmers arrived in northern Europe armed with their greedy plants, they learned a lot about food from the local hunter-fisher-gatherers, and vice-versa, but without much interbreeding. Jeremy interviews one of the authors on his podcast.
- Early contact between late farming and pastoralist societies in southeastern Europe. There was extensive interbreeding between farmers and the local transitional foragers/herders before with the expansion of pastoralist groups into Europe from the Eurasian steppes around 3300 BC.
- Isotopes prove advanced, integral crop production, and stockbreeding strategies nourished Trypillia mega-populations. The earliest European mega-settlements, in Ukraine and Moldova, from around 4000 BCE, integrated greedy crops and generous domesticated livestock.
- Inference of Admixture Origins in Indigenous African Cattle. Following introduction from the Near East, domesticated cattle got admixed with a North African extinct aurochs before spreading throughout Africa.
- Flax for seed or fibre use? Flax capsules from ancient Egyptian sites (3rd millennium BC to second century AD) compared with modern flax genebank accessions. Fibre first.
- Revealing the secrets of a 2900-year-old clay brick, discovering a time capsule of ancient DNA. DNA from 34 plant groups were detected inside an old brick when it happened to break.
- Making wine in earthenware vessels: a comparative approach to Roman vinification. Comparison with modern counterparts shows that Roman clay jars for storing wine were integral to the process. No word on whether there was any ancient DNA in the clay.
- Breadfruit in the Pacific Islands, its domestication and origins of cultivars grown in East Polynesia and Micronesia. Spoiler alert: they came from Polynesian Outlier Islands.
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.
