- Can bison play a role in conserving habitat for endangered sandhills species in Canada? Maybe, hence the recommendation to re-introduce them. Incidentally, there are a few crop wild relatives on the list of threatened plants of Canada.
- Genetic improvement of farmed tilapias: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments. The 10-year “Genetic Improvement of Farmed Tilapias” (GIFT) project was not a complete waste of time. The GIFT population will respond well to selection for increased body mass, and you dont have to do the evaluation in lots of different environments.
- Mycorrhizal colonization of major banana genotypes in six East African environments. Different banana genotypes had different levels of infection, but environment also plays an important role. Important because arbuscular mycorrhizal fungi may increase production.
- On the use of depth camera for 3D phenotyping of entire plants. An example of this.
- Genetic and phenotypic diversity in a germplasm working collection of cultivated tropical yams (Dioscorea spp.). Should be a good starting point for improvement programmes. Kind of like the GIFT population, then, eh? But starting point? Haven’t people been breeding yams for a while?
- Cytogeography of the Humifusa clade of Opuntia s.s. Mill. 1754 (Cactaceae, Opuntioideae, Opuntieae): correlations with pleistocene refugia and morphological traits in a polyploid complex. The southeastern and southwestern U.S. represent glacial refugia for diploid members of the clade, and a whole bunch of polyploids resulted when the taxa spread out again after glacial episodes. How many of these are eaten is what I’d like to know, and whether ploidy affects that. I suppose climate change will lead to further complications?
- The impact of agricultural intensification and land-use change on the European arable flora. Is significant. Not least because some crop wild relatives are involved, although that’s not really discussed here.
Nibbles: US Farm Bill, Polish chicks, Young Kenyan farmers, Jowar redux, Handwriting, Erna Bennett, Ant mutualism, Horizontal plastid movement, Horizon scanning
- Policy wonks start to worry about the next US Farm Bill and its effects on poor farmers elsewhere.
- Poles start to worry about their endangered chicks.
- The Youth in Agriculture gives agricultural biodiversity some love on St Valentine’s Day.
- “Can jowar ever replace rice?” Question expecting the answer no? (Jowar is sorghum.)
- Can anyone actually decipher what H.G. Wells wrote to FAO Director Lubin?
- A Memorial Service will be held for Erna Bennett, in English, at 12.30 hrs. on Friday, 9th March at Santa Balbina Church, Viale Guido Baccelli, Rome. It’s near FAO. And no, there’s no link.
- Ants help crop wild relative (among other things).
- Plastids move between crop and wild relative.
- Cambridge boffins look into crystal ball and see fully sequenced, N-fixing perennial cereals growing under sterile conditions. In deep ocean vents.
NGS and genebanks free for a limited time only
Quick, the AmJBot Special Issue on the applications of next-generation sequencing in botany is officially out, and some of the papers are actually free! Including the one on genebanks. And yes, I haven’t forgotten I promised to blog about it. But there’s rather a lot of it to digest…
Brainfood: Chicken domestication, Financial crisis and conservation, Cucurbit domestication, Tamarind future, Biofortification via bacteria, Cowpea nutritional composition, Roman bottlegourd, Noug, Rice blast diversity, Pearl millet domestication, Cacao genotyping, Organic ag, Marcela, In situ vs ex situ, Artocarpus roots
- Heritable genome-wide variation of gene expression and promoter methylation between wild and domesticated chickens. Domestication was Lamarckian.
- Global economy interacts with climate change to jeopardize species conservation: the case of the greater flamingo in the Mediterranean and West Africa. Financial crisis leads to closing down of Mediterranean saltpans, which is not good news for flamingo. Climate change doesn’t help. Must be similar examples for plants, Shirley.
- Parallel Evolution Under Domestication and Phenotypic Differentiation of the Cultivated Subspecies of Cucurbita pepo (Cucurbitaceae). C. pepo subsp. pepo and subsp. texana underwent similar genotypic and phenotypic changes during domestication.
- Ecological and human impacts on stand density and distribution of tamarind (Tamarindus indica L.) in Senegal. Climate change will lead to an area of currently low density in the NW being a refugium. Connectivity problems will ensue.
- Biofortification of wheat through inoculation of plant growth promoting rhizobacteria and cyanobacteria. Breeders give up.
- Nutritional ranking of 30 Brazilian genotypes of cowpeas including determination of antioxidant capacity and vitamins. Breeders take heart.
- A short history of Lagenaria siceraria (bottle gourd) in the Roman provinces: morphotypes and archaeogenetics. Out of Asia. And more.
- Functional Properties, Nutritional Value, and Industrial Applications of Niger Oilseeds (Guizotia abyssinica Cass.). It has them, in spades, as this paper summarises.
- Sex at the origin: an Asian population of the rice blast fungus Magnaporthe oryzae reproduces sexually. The Himalayan foothills would seem to be the place where to look for resistance.
- Evolutionary History of Pearl Millet (Pennisetum glaucum [L.] R. Br.) and Selection on Flowering Genes since Its Domestication. Bayesian modelling of 20 random genes supports domestication about 4,800 years ago, with protracted introgression from the wild relative, and selection sweeps suggest flowering related genes unsurprisingly underwent strong selection as the crop spread southward. But a single domestication scenario? Anyway, sounds familiar, doesn’it.
- Genome-Wide Analysis of the World’s Sheep Breeds Reveals High Levels of Historic Mixture and Strong Recent Selection. Much like, ahem, pearl millet. For flowering genes, read horniness genes. The bit about an initially broad sampling of diversity sounds a bit like the horse. Who out there is going to synthesize all this domestication stuff? Not that I’m looking for a meta-narrative, mind.
- Ultra-barcoding in cacao (Theobroma spp.; Malvaceae) using whole chloroplast genomes and nuclear ribosomal DNA. Well, sequence the whole thing and be done with it is what I say, why flaff around with ultra-this and super-that?
- The crop yield gap between organic and conventional agriculture. 20%.
- Marcela, a promising medicinal and aromatic plant from Latin America: A review. Achyrocline satureioides, in the Asteraceae. Yeah, I never heard of it either. But these guys say it’ll make you rich and beautiful.
- Comparative genetic structure within single-origin pairs of rice (Oryza sativa L.) landraces from in situ and ex situ conservation programs in Yunnan of China using microsatellite markers. 2-5 times more unique alleles in the in situ version of various landraces compared to the ex situ version, collected in 1980. But same number of common alleles.
- Mutualism breakdown in breadfruit domestication. More recent cultivars have less abundant and less species-rich arbuscular mycorrhizas.
Nibbles: Marker assisted selection, Ecoagriculture, Tomato grafting, Food sovereignty, Rice genomes, Other genomes, Molecular toolkit, Yaks, Evotourism, Sandalwood
- Yale University magazine drinks the fast-track breeding KoolAid panacea.
- Compare and contrast. Repeat. Endlessly.
- Grafting tomatoes is hot for lots of reasons; but how does it protect against leaf-borne diseases? And not just tomatoes, actually.
- Getting the lowdown on that “food sovereignty” farrago.
- And today’s DNA sequencing will solve world hunger and cure bunions story.
- Genomics also good for “health, agriculture, livestock, fisheries and biodiversity” in Philippines. Have we forgotten anything?
- Well yeah, you forgot your handy molecular toolkit.
- Meanwhile, back in the real world, the choice is between forests and yaks.
- More hard choices: evotourism destinations. But check it out, there be agricultural biodiversity too!
- And another one: to go to the International Sandalwood Symposium, or not to go?
