- Genetic structure and domestication of carrot (Daucus carota subsp. sativus) (Apiaceae). Origin in Central Asia, but no genetic bottleneck (sic).
- Data collection and assessment of commonly consumed foods and recipes in six geo-political zones in Nigeria: Important for the development of a National Food Composition Database and Dietary Assessment. Nigerians eat a lot of soup.
- The integration of crop rotation and tillage practices in the assessment of ecosystem services provision at the regional scale. Good trick if you can do it.
- Nutritional composition of minor indigenous fruits: Cheapest nutritional source for the rural people of Bangladesh. If only the rural people knew about this.
- Effectiveness of selection at CIMMYT’s main maize breeding sites in Mexico for performance at sites in Africa and vice versa. Is high. Phew.
- Olive trees as bio-indicators of climate evolution in the Mediterranean Basin. Olives in Germany by 2100?
- Crop genetic diversity benefits farmland biodiversity in cultivated fields. Mixed wheat fields better for soil invertebrate biodiversity than fields with single varieties.
- IT background of the medium-term storage of Martonvásár Cereal Genebank resources in phytotron cold rooms. The interesting thing is that the system links genebank data with breeders’ data. Don’t see that a lot.
Conserving Prunus africana?
I’ve been sitting on it for a while, but a paper which AoB Blog discussed back in January led me to uncover a whole load of stuff on Prunus africana. The African Cherry Tree does not rate a leaflet in the African Food Tree Species series, perhaps because it’s not a, well, food tree, but that doesn’t mean it’s not important.
Chemicals extracted from the tree’s bark are used in a range of pharmaceutical products to treat enlarged prostate (benign prostatic hyperplasia), an extremely common condition that affects up to half of men aged over 50.
Hence various efforts to develop sustainable harvesting methods. And also an interesting series of diversity and demographic studies:
- Phylogeography of the Afromontane Prunus africana reveals a former migration corridor between East and West African highlands: “The high genetic similarity found between western Uganda and west African populations indicates that a former Afromontane migration corridor may have existed through Equatorial Africa.”
- Structural diversity and regeneration of the endangered Prunus africana (Rosaceae) in Zimbabwe: “…poor regeneration, fewer P. africana trees in small and large size classes, dominance of positive height and diameter differentiation and high mingling.”
- Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands: “The observed patterns indicate divergent population history across the continent most likely associated to Pleistocene changes in climatic conditions. The high genetic similarity between populations of West Africa with population of East Africa west of the Eastern Rift Valley … provides further evidence for a historical migration route. Contrasting estimates of recent and historical gene flow indicate a shift of the main barrier to gene flow from the Lake Victoria basin to the Eastern Rift Valley…”
- Modelling the potential distribution of endangered Prunus africana (Hook.f.) Kalkm. in East Africa: “Prunus africana distribution is thus highly vulnerable to a warming climate and highlights the fact that both in-situ and ex-situ conservation will be a solution to global warming.”
Maybe we could do with some more seed behaviour data. But it would seem there is now plenty of diversity, demographic and sustainable harvesting information on which to base a comprehensive conservation strategy. Is someone coming up with one?
Nibbles: African food, Cattle grazing, Young farmers, Seed policy, Traditional medicine, Litchis, Land use, Perennial sorghum
- Today’s Nibbles is a Kenya edition. Just because.
- But we’ll start with an African foodie revolution that is passing that country by.
- Cattle need diverse foods too, so don’t neglect those forbs, Kenyans.
- A young Kenyan turns to vegetable growing. Not, alas, of the traditional kind. Yet.
- Well, he better get a move on, because it says here people are after his seeds.
- Seeds are what the traditional medicine industry could do with.
- I guess there’s always litchis.
- Wonder what they’ll do to land use patterns.
- But will there ever be perennial sorghum?
Nibbles: FAO Commission, Alpine plants conference, Young breeders, Indian sorghum, Pastoralists in the media, Neglected genomics, More quinoa, Cape Gooseberry in Europe, Database hell, Tomayto tomahto, Maple syrup, Double cropping, Cloning trees, Belated Earth Day, UK Plant Science Week
- Summary of that 14th Session of the CGRFA we were all following last week.
- Conferences on “Changes in alpine and arctic flora under climate change” we’ll all be following in September. If you’re from Balkans, Caucasus, Central Asia, the organizers need you in particular. But hurry, before it’s too late!
- In other news, young scientists are into beer.
- India’s Directorate of Sorghum Research gets a genebank. Relationship with NBPGR unclear.
- Media portrayals of pastoralists in Kenya, China and India: The Report. The Brief. The Press Release. ILRI reaction?
- Neglected crops get the genomic treatment. And why that might be a good thing.
- CIAT wades in on quinoa.
- Call for information on Physalis peruviana cultivation in Europe.
- Biodiversity databases have errors! Shock! Horror! Probe!
- The nutritional difference between organic and conventional tomatoes deconstructed.
- Your maple sugaring questions answered. Nice idea.
- Double crop for development. I guess that’s the sustainable intensification everyone is talking so much about.
- If in doubt, clone it!
- Wait, wait, wait, we missed Earth Day?
- And also a bunch of UK plant science conferences. (I had of course linked to the storifications here originally, but they’ve gone now of course.)
Brainfood: Viruses, Allium genomic size, Acacia adaptation, Local carp, Chinese onions, Bull genetic info, Ecosystem services, Sahelian ag
- New threats to endangered Cook’s scurvy grass (Lepidium oleraceum; Brassicaceae): introduced crop viruses and the extent of their spread. Introduced crop virus threatens endemic.
- Role of adaptive and non-adaptive mechanisms forming complex patterns of genome size variation in six cytotypes of polyploid Allium oleraceum (Amaryllidaceae) on a continental scale. It’s not the environment.
- Evolution and ecology meet molecular genetics: adaptive phenotypic plasticity in two isolated Negev desert populations of Acacia raddiana at either end of a rainfall gradient. It’s the environment.
- Using biodiversity to valorise local food products: the case of fish ponds in a cultural landscape, their biodiversity, and carp production. It could work, if only people liked to eat carp and knew what biodiversity was.
- Phenotype and genetic diversity in potato onion cultivars from three provinces of northeast China. In other news, there’s something called a potato onion. Otherwise, this is actually a deeply boring paper.
- The value of genetic information to livestock buyers: a combined revealed, stated preference approach. Low to none, for now.
- Ecosystem Services. Latest issue includes a bunch of interesting reviews, and an editorial summarizing each in like a paragraph. Great service, great value. See what I did there?
