- The elephant grass (Cenchrus purpureus) genome provides insights into anthocyanidin accumulation and fast growth. It’s related to pearl millet, apparently. Which may or may not be a good thing. No word on any genes so far untapped for improvement.
- Triticum population sequencing provides insights into wheat adaptation. Wide adaptation is largely due to introgression from the wild. No word on any genes so far untapped for improvement.
- The Right Tortilla for the Right Occasion: Variation in Consumers’ Willingness to Pay for Blue Maize Tortillas Based on Utilization. Consumers are willing to pay 42% more for blue tortillas, but only when eating out, presumably as part of virtue signalling.

- Origins and genetic legacy of prehistoric dogs. All dogs are descendants of a now extinct wolf population, and their genetics show both interesting parallels with, and divergences from, that of humans.
- Brain Size Does Not Rescue Domestication Syndrome. Not even for humans, I suspect. Kidding apart, this is fascinating. It suggests that, for animals at least, the domestication syndrome is not actually a thing. Or at least has not been properly tested. If there’s interest, I’ll do a full post. Let me know in the comments below.
- Ancient genomes reveal tropical bovid species in the Tibetan Plateau contributed to the prevalence of hunting game until the late Neolithic. The now tropical gaur ranged much further north during the warmer Neolithic, which facilitated the exploration of the Tibetan Plateau.
- Optimization of in vitro germination and cryopreservation conditions for preserving date palm pollen in the USDA National Plant Germplasm System. Always good to have another way of storing germplasm.
- Beyond the material: knowledge aspects in seed commoning. Comparing global with local seed commons reveals importance of managing knowledge, both scientific and traditional.
- Genetics to the rescue: managing forests sustainably in a changing world. To manage forests sustainably, you have to conserve and use their genetic diversity. Interesting that they needed a conference to work that out.
- Genetic mixing for population management: from genetic rescue to provenancing. And using that genetic diversity could mean mixing it up.
- The importance of genomic variation for biodiversity, ecosystems and people. Maintaining ecosystem services means maintaining genetic diversity. Sounds like these authors went to the same conference.

- Agricultural diversification promotes multiple ecosystem services without compromising yield. Meta-meta-analysis shows diversification is good for biodiversity, pollination, pest control, nutrient cycling, soil fertility, and water regulation and not bad for crop yields either.
- Holocene land and sea‐trade routes explain complex patterns of pre‐Columbian crop dispersion. Cherimoya reached the Andes by boat.
- Safeguarding and using global banana diversity: a holistic approach. 1617 banana accessions from 38 countries maintained in an in vitro collection, backed-up in cryo; over 18,000 samples distributed to researchers and farmers in 113 countries in 35 years. And that’s just the basics.
- Designing sustainable pathways for the livestock sector: the example of Atsbi, Ethiopia and Bama, Burkina Faso. It’s not just a straight choice between intensive or extensive production, stop with the dichotomies.
- Moving health to the heart of agri-food policies; mitigating risk from our food systems. It’s difficult to separate food from health; and yet…
- Genes derived from ancient polyploidy have higher genetic diversity and are associated with domestication in Brassica rapa. Agriculture depends on polyploidy.
- Genetic diversity is indispensable for plant breeding to improve crops. Plant breeding from an industry perspective, using the Brassicaceae as a case study.
- Yield, yield stability and farmers’ preferences of evolutionary populations of bread wheat: A dynamic solution to climate change. A totally different perspective to the above, using a totally different crop. Compare and contrast.
- Enhancing seed conservation in rural communities of Guatemala by implementing the dry chain concept. Cool way for farmers to save their seeds so they can do the above.
- Landrace hotspots identification in Europe. Where to implement the above.
- Innovation and the commons: lessons from the governance of genetic resources in potato breeding. This is a tricky one. Near as I can figure it, the authors are trying to say that it’s difficult to govern genetic resources apart from the tools needed to develop and use them. But hey, you have a go.
- Conservation of Native Wild Ivory-White Olives from the MEDES Islands Natural Reserve to Maintain Virgin Olive Oil Diversity. I did not have an endemic insular wild albino olive on my bingo card.

- On the origin and dispersal of cultivated spinach (Spinacia oleracea L.). Spinach originated more eastward than often thought.
- What plant is that? Tests of automated image recognition apps for plant identification on plants from the British flora. Botanists shouldn’t give up their day jobs.
Brainfood: Now what edition
- Image-Based Goat Breed Identification and Localization Using Deep Learning. Fancy maths can identify goat breeds from photos. Ok, cool, now what?
- AI Naturalists Might Hold the Key to Unlocking Biodiversity Data in Social Media Imagery. Fancy math can often identify common flowers on Flickr. Ok, cool, now what?
- FoodMine: Exploring Food Contents in Scientific Literature. Fancy maths can trawl the literature to pick out the chemical components of different foods. Ok, cool, I guess, now what?
- Cultural and linguistic diversities are underappreciated pillars of biodiversity. Well, yeah. But now what?
- Global priority areas for ecosystem restoration. Fancy maths says restoring 15% of converted lands in identified priority areas could avoid 60% of expected extinctions while sequestering 30% of the total CO2 increase in the atmosphere since the Industrial Revolution. Cool, now what?
- An unexpectedly large count of trees in the West African Sahara and Sahel. Wait, does that mean some of the above won’t be necessary?
- Cost and affordability of nutritious diets at retail prices: Evidence from 177 countries. Fancy maths shows that nutritious diets are almost 3 times as expensive as diets supplying basic energy needs, and costs increase with remoteness. Ok, cool, now what?
- Phylogenetic inference enables reconstruction of a long-overlooked outbreak of almond leaf scorch disease (Xylella fastidiosa) in Europe. The olive plague started on almonds. Ok, now what though?
- Genome-wide association study in accessions of the mini-core collection of mungbean (Vigna radiata) from the World Vegetable Gene Bank (Taiwan). Genotyping, phenotyping and fancy maths find that mungbean could grow in temperate conditions. Ok, cool, now what?
- Enhancing the searchability, breeding utility, and efficient management of germplasm accessions in the USDA−ARS rice collection. Genotyping and fancy maths can improve genebank management. Well, yeah, but now what? No, wait, we know exactly now what: digital genebanks!
- Ok, that was a bit of fun, but the important point is that research, no matter how cool, is only the beginning.

- Germplasm Acquisition and Distribution by CGIAR Genebanks. A lot of stuff going in, a lot of stuff coming out, to everyone’s benefit. 35 years of data, with special focus on the last 10.
- Intraspecific diversity as a reservoir for heat-stress tolerance in sweet potato. 132 out of 1973 accessions tolerant of heat, though in different ways. A prime example of the above benefits.
- Identification and characterization of high‐yielding, short‐duration rice genotypes for tropical Asia. Short-duration varieties will need to be a bit taller and leafier to yield more. Another example of the above benefits.
- Modelled distributions and conservation priorities of wild sorghums (Sorghum Moench). More stuff needs to go into the above genebanks, though, for example from N. Australia.
- Ex situ and in situ conservation gap analysis of crop wild relative diversity in the Fertile Crescent of the Middle East. Same from the Fertile Crescent.
- In situ and ex situ conservation gap analyses of crop wild relatives from Malawi. And not just the above genebanks either.
- The Potential of Payment for Ecosystem Services for Crop Wild Relative Conservation. Ok, we have the gaps (see above), and now here we have the method. What’s stopping us?
- Assessing under-Estimation of Genetic Diversity within Wild Potato (Solanum) Species Populations. Wild diploid species more diverse than previously thought. So providing more ecosystem services?
- Genetic diversity and differentiation of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. in the Hajar Mountains of Oman. No word on the ecosystem services being provided.
- The investigation of minor and rare Tunisian olive cultivars to enrich and diversify the olive genetic resources of the country. Rare + minor doesn’t mean bad. But maybe an influx of Omani genes would help?
- Biobanking of vegetable genetic resources by in vitro conservation and cryopreservation. Yes, even for vegetables.
- From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection. Four subpopulations: Calabrese broccoli landraces, hybrids, sprouting broccoli, and violet cauliflower. Diversity in modern varieties decreasing with time.
- Crop switching reduces agricultural losses from climate change in the United States by half under RCP 8.5. But it will have to be a lot of switching. Hopefully out of broccoli.
- The mosaic genome of indigenous African cattle as a unique genetic resource for African pastoralism. An influx of zebu genes about a thousand years ago is responsible for the success of African pastoralism.
- Protection of traditional agricultural knowledge and rethinking agricultural research from farmers’ perspective: A case from Turkey. Against power imbalances the gods themselves contend in vain.

- Agricultural Food Production Diversity and Dietary Diversity among Female Small Holder Farmers in a Region of the Ecuadorian Andes Experiencing Nutrition Transition. Higher diversity of crops on family farms is only weakly associated with greater dietary diversity and lower household food insecurity among female caretakers. Better than nothing, though, right?
- Productive Capacity of Biodiversity: Crop Diversity and Permanent Grasslands in Northwestern France. Having a bigger percentage of permanent grassland on your French farm, or a greater diversity of crops, can increase cereal and milk yields. No word on diets.
- The influence of landscape composition and configuration on crop yield resilience. No effect on yield per se (see above), but proximity to semi-natural habitat does increase yield stability in UK farms.
- Living off the land: Terrestrial-based diet and dairying in the farming communities of the Neolithic Balkans. Ancient farmers had a varied diet, but possibly not involving consumption of raw milk, at least by adults.
- Food securers or invasive aliens? Trends and consequences of non-native livestock introgression in developing countries. In 40 countries, the proportion of livestock populations belonging to local breeds has been decreasing by about 1% a year for the past 20 years. Hey, but milk yield per cow has been going up, so there’s that.
- Potentials of Cultivated Varieties and Wild Yam Seeds as Efficient Alternative Plant Genetic Resources for Resistant Genotypes against Yam Mosaic Virus (YMV) in Togo. Work with seeds! But were they properly inoculated? Hopefully a virologist will tell us.
- Genome-wide association analysis reveals new insights into the genetic architecture of defensive, agro-morphological and quality-related traits in cassava. Lots of interesting markers for cassava breeders, or at least those working with material from W Africa. Do it for yams next?
- High-resolution satellite imagery applications in crop phenotyping: An overview. Clouds, you say? Not a problem any more. But can it distinguish landraces from modern varieties? What’s needed is a sort of mutant algorithm, I guess.
- Crop type identification and spatial mapping using Sentinel-2 satellite data with focus on field-level information. Still some way from being able to distinguish landraces from modern varieties, I see.
- Global forest restoration and the importance of prioritizing local communities. I’m shocked I tell you, shocked.
- Protection gaps and restoration opportunities for primary forests in Europe. A lot of restoration could usefully be done in currently protected areas, though it would be better if these were expanded. No word on local communities.
- Mapping the forest disturbance regimes of Europe. I guess this means that restoration, when it happens, will be monitored from space.
- Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation. When you do do restoration, don’t worry about genetic pollution, just go for as much diversity as possible. Well, for small relict populations. Of animals.
- Considerations for large-scale implementation of dormant budwood cryopreservation. It’s about the logistics.
- Development of a fast and user-friendly cryopreservation protocol for sweet potato genetic resources. It’s the axillary meristems. Among other things.
- The human–environment nexus and vegetation–rainfall sensitivity in tropical drylands. Dryland grasslands in Africa and Asia less able to respond to water availability overall, more able in Australia and S America, evens stevens in N America. Would be interesting to mash up particularly hard-hit areas with CWR and forage germplasm collecting localities.
- Botanic garden solutions to the plant extinction crisis. Expertise, tools, facilities, and networks are there. You know what’s missing, right?
