Ghostly Bramley

I don’t think I linked last year to the sad news of the impending demise of the original Bramley apple tree. I did link a year before to the news that the pie filling made from said apple was being protected by the EU. And I’ll link now to an article about what Brexit may mean for British apple growers. But all merely by way of introduction to this stunning 3D scan of that fading mother tree in Southwell.

Nibbles: Rice in Trinidad, Sweet potatoes in Ethiopia, EU crop diversity double, Sir Peter on the ginkgo, Forages, Brazilian peanuts, Seed moisture, Phenotyping double, Svalbard deposit, CATIE data, Herbarium double, Seed #resistance, Father of the apple, Agave congress

African rice out of Africa, and out of the genebank.
The other way around for sweet potato.
Markers for micronutrients. And diversity for taste…
The deep history of the ginkgo.
Study plants to decrease the effects of burping.
Brazil rationalizes peanut collections.
Measuring moisture in seeds.
Big data for better seeds. And not only in Iowa.
NZ seeds in Svalbard.
CATIE on Genesys.
Oz biosecurity fail. Better stick to online.
I want to be a seed rebel too.
Maybe in Kazakhstan?
Agave under the volcano under the cosh.

Citrus in a nutshell

Look, I suppose I could try and explain that recent Citrus phylogeny paper in Annals of Botany. But am I really likely to do better than this graphic?

I didn’t think so.

Important to know what’s what. But if all that’s just too much for you, wind down by listening to Helena Attlee on Eat this Podcast on citrus in Italy.

Old school genebank documentation

Call me a dinosaur, but I like this sort of stuff. A proper printable catalogue of all the material in a collection, with photographs and all, in this case the 200+ olive varieties in Italy’s Centro di Ricerca per l’Olivicoltura e l’Industria Olearia. ((Don’t worry, there’s biochemical and molecular stuff on the second page of each variety entry.)) No doubt all the info is in the appropriate database, where it can be compared to the holdings of other institutes and all. But I’m still grateful for the PDF version.

Brainfood: Cannabis roundup, Citrus genomes, Mapping Africa, Maize diversity, Qat diversity, Language diversity, Apple taste, Coconut diversity, Napier grass review, Rangeland management, Chinese goats, Arabica evaluation, Bangladeshi chickens, Seed endophytes

Cannabis Domestication, Breeding History, Present-day Genetic Diversity, and Future Prospects. The weed is in trouble, man. Just one of the papers in a very special issue of Critical Reviews in Plant Sciences. And for a historical perspective…
Genomic analyses of primitive, wild and cultivated citrus provide insights into asexual reproduction. Apomixis is down to a “miniature inverted-repeat transposable element insertion in the promoter region of CitRWP.”
Automated cropland mapping of continental Africa using Google Earth Engine cloud computing. Croplands increased by 1 Mha/yr between 2003 and 2014.
Genetic diversity and population structure of native maize populations in Latin America and the Caribbean. Three groups: Mexico + southern S. America, lowland Mesoamerica + Caribbean, Andes.
Phylogeography of the wild and cultivated stimulant plant qat (Catha edulis, Celastraceae) in areas of historical cultivation. Centres of origin in Kenya and Ethiopia, with limited movement between the two, but some hybrids in N. Kenya; the Yemeni stuff came from Ethiopia.
Process-based modelling shows how climate and demography shape language diversity. If you assume human groups split after reaching a certain population size, and rainfall limits population density, you can predict language diversity in Australia.
Volatile Compound Profiles of Malus baccata and Malus prunifolia Wild Apple Fruit. Look at the esters.
Genetic diversity, population structure and association analysis in coconut (Cocos nucifera L.) germplasm using SSR markers. I can’t see much new here. Please, coconut experts, tell me what I’m missing.
Opportunities for Napier Grass (Pennisetum purpureum) Improvement Using Molecular Genetics. Could do better.
Heterogeneity as the Basis for Rangeland Management. Gotta mix it up.
Analysis of genetic diversity of Chinese dairy goats via microsatellite markers. The locally developed breeds are all derived from a single European breed.
Variation in bean morphology and biochemical composition measured in different genetic groups of arabica coffee (Coffea arabica L.). You can’t use morphology to predict taste.
Breeding for the improvement of indigenous chickens of Bangladesh: evaluation of performance of first generation of indigenous chicken. I don’t understand this much, but I liked the names of the genotypes: Naked Neck, Hilly and Non-descript Desi.
Persistence of endophytic fungi in cultivars of Lolium perenne grown from seeds stored for 22 years. It’s a record!
