- A domestication assessment of the big five plant families. Half of cultivated plants are legumes, a third grasses.
- The vulnerability of US apple (Malus) genetic resources. Moderate.
- Microorganisms associated with amylolytic starters and traditional fermented alcoholic beverages of north western Himalayas in India. Veritable microbial communities.
- Spatial incongruence among hotspots and complementary areas of tree diversity in southern Africa. It’s not just about the hotspots.
- Integrating Agricultural and Ecological Goals into the Management of Species-Rich Grasslands: Learning from the Flowering Meadows Competition in France. Gotta document the synergies.
- Genetic–geographic correlation revealed across a broad European ecotypic sample of perennial ryegrass (Lolium perenne) using array-based SNP genotyping. Strong structure both with latitude and longitude. Wonder if the Flowering Meadows competition took that into account.
- Interactions of knowledge systems in shiitake mushroom production: a case study on the Noto Peninsula, Japan. Tradition is not always a totally good thing.
- Development of Core Sets of Dolichos Bean (Lablab purpureus L. Sweet) Germplasm. Heuristic is better. But is it PowerCore?
- Genetic Diversity of Local and Introduced Sweet Potato [Ipomoea batatas (L.) Lam.] Collections for Agro-morphology and Physicochemical Attributes in Ethiopia. The improved varieties are not all that great. But there were only two of them. And the local landraces were not necessarily the best.
- Study of genetic variability in Vitis vinifera L. germplasm by high-throughput Vitis18kSNP array: the case of Georgian genetic resources. Some differentiation between wild and cultivated, but significant overlap.
Of plants and their pests
For whatever reason, there was a spate of papers on the coevolution of plants and their pests last week. Or at least I got to hear about them last week.
The one that got the most attention by the popular press — well, actually, the only one that got any attention by the popular press — was a study comparing changes in glucosinolates in the brassica family with speciation in the Pieridae butterflies, whose caterpillars feed on these plants. Glucosinolates give wasabi and mustard their zing (hence the press interest), but are deadly to insects, which is why they evolved in the first place. Each major innovation in the chemistry of glucosinolates since they first arose in the brassicas at the K-T boundary is correlated, the authors found, with a burst of diversification in detoxification mechanisms among the insects at which they were aimed.
The other two studies don’t delve quite so deeply back into evolutionary time, focusing on the role of domestication. The first looked at populations of the green peach aphid (Myzus persicae) growing on a diversity of both crops and their wild relatives. The authors found that aphid populations on domesticated species were more genetically diverse, but evolved more slowly, because selection was less strong and populations larger, weakening the effect of genetic drift. Applying this result to the brassica-butterfly model would suggest that the strength of the association between glucosinolate and butterfly diversity should decrease for the domesticated brassicas compared to the wild ones, but I’m not sure this was looked at in that study.
The third paper investigated the apple’s fungal pathogen Venturia inaequalis. The dispersal characteristics of dozens of strains collected on both domesticated and wild apples in Kazakhstan were compared. The authors found that apple domestication has led to enhanced colonization capacity by the pathogen: strains from orchards have more, bigger spores. Seems to me that’s somewhat contradictory to the aphid example.
The relationship between plants and their pests is, well, complicated.
Nibbles: AVRDC genebank, Grits, Sikhs & parmesan, Congolese gouda, New rice, Poisonous plants, Bush tucker, Co-evolution, Amazonian medicinals, Native American usufruct
- World Vegetable Centre looking for a genebank manager.
- What’s a grit?
- Who did you say saved parmesan? Who did you say is making gouda?
- Philippines gets some new rice varieties. No, but these are climate-resilient.
- A poisonous plants gardens fits perfectly with my mood today.
- Involve native people in the development of a native foods industry. Well, duh.
- Blame butterflies for broccoli.
- There are a lot of medicinal plants in the Amazon.
- Wild rice (wild but not rice) vs pipeline.
Nibbles: Pope, CGIAR, Agroecology, ABS, Food shortage, World flora, Nutella, Bees, GMOs, CC & wheat, CC & legumes, EU satellite, Seed saving, Wheat breeding, Strawberry breeding, Adopt-a-crop, Organic tea, Malagasy yams, Seed app, Ebola seeds, Sorghum spoons
And we’re back! While we were away…
- …the Pope pontificated on climate change and GMOs, among other things.
- And so did the CGIAR.
- Boffins in the UK suggested that agroecology might be important to sustainable intensification. No word on whether the CGIAR is listening.
- Bioversity asked for contributions on whether ABS can support farmers. No word on whether anyone is listening.
- And The Economist asked: who cares, anyway?
- Google said it would help botanists catalogue all plants.
- Nutella was bad, and then ok again.
- Bees were again found to be important to agriculture, but not all bees.
- The pros and cons of GMOs were trotted out again. And again.
- Climate change was blamed for smaller loaves of bread. Which as far as I can tell might not be a totally bad thing.
- And for the need to grow drought-resistant legumes.
- The EU launched a satellite to monitor crops.
- Meanwhile, people just got on with it, in their own, sometimes weird, way…
- …breeding wheat. Even organic wheat. Even perennial. Even in Scotland.
- …breeding strawberries. Even with wild relatives.
- …or just adopting the raw materials of breeding.
- Growing organic tea in China.
- Conserving yams in Madagascar.
- Trying to find the appropriate seeds to grow in Kenya.
- And giving probably inappropriate seeds to Ebola-hit farmers.
- Which they can now eat using sorghum spoons.
Nibbles: EU meet, Green cities, Gates strategy, Indigenous hunger, Niche coffee, Salinity, Botany rules, Pollinator evidence, Sacred cows, Coke bottles
- A couple of EU DGs discuss farming for diversity, maybe even diversity in farming?
- They recently heard about urban farming from FAO, which might help. Oh no, wait, that’s a different DG.
- Gates Foundation doubles down on nutrition, nice to see agriculture in the mix too.
- Meanwhile, efforts are underway to measure the food security of indigenous people in better ways, so that we can figure out whether things like the above are actually working.
- Sourcing high quality coffee. I think we can all get behind that goal.
- Deconstructing salt tolerance in chickpea.
- Botany has an image problem. No, really?
- Fact-checking pollinator decline.
- Only local cows for Haryana. Seems extreme? Well, Michigan not above doing the same.
- Coca-Cola has plant-based bottles. Now to embed some seeds in them.
- Maybe Swedish vegetable seeds. Do they have Coke in Sweden?
