- 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.

- 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.

- 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?
Brainfood: Tea, NGS, Grandmothers, Anti-scorbutics, Barley population structure, Climate change below ground, Rice
- Genetic structure and diversity of India hybrid tea. It’s complicated. It’s important because the success of tea outside its core are is due to hybridization between Indian and Chinese types in Assam starting in 1875. It’s limited.
- NGS technologies for analyzing germplasm diversity in genebanks. That’s Next-Generation Sequencing. Can be used to “identify patterns of genetic diversity, map quantitative traits and mine novel alleles.” Recommendation is for “genotyping by sequencing” to be applied stepwise, starting with a core collection. That’ll be complicated, but the real bottleneck will be the phenotyping.
- The role and influence of grandmothers on child nutrition: culturally designated advisors and caregivers. Wise up, nutrition advocates. You are, apparently, ignoring egg-suckers, a primary force for good.
- The importance of eating local: slaughter and scurvy in Antarctic cuisine. Who needs oranges when you have fresh penguin at hand?
- Islands and streams: clusters and gene flow in wild barley populations from the Levant. There is ecogeographic patterning in the wild material, once you remove the effect of recent admixture with cultivated barley. Geneflow is more N to S than vice versa.
- Global change belowground: impacts of elevated CO2, nitrogen, and summer drought on soil food webs and biodiversity. It’s complex, really complex; increased CO2 and N may result in new, simpler belowground assemblages.
- Rice and Language Across Asia: Crops, Movement, and Social Change. An entire issue of Rice journal.
A Green Revolution for trees
Prof Roger Leakey, sometime of ICRAF (among other places), where he pioneered tree domestication in support of rural livelihoods, and now Vice Chairman of the International Tree Foundation, has a fascinating new book in the offing.
In contrast to the doom and gloom often emanating from the tropics, ‘Living with the Trees of Life’ illustrates how many different aspects of agricultural science can be combined into a more robust approach to farming, which will be productive, as well as more environmentally and socially sustainable. This approach uses agroforestry as a delivery mechanism for multifunctional agriculture aimed at addressing the cycle of land degradation and social deprivation in the tropics. A key role in this is played by the ‘Trees of Life’, the large number of indigenous trees that produce marketable fruits, nuts, medicines and other products of day-to-day importance in the lives of local people throughout the tropics.
The book promises to be very practical.
A 3-step approach is described which can be used to close the Yield Gap (the difference between the yield potential of food crops and the yields actually achieved by farmers). This pays special attention to land husbandry and to the wise use of the natural resources which support agriculture and the livelihoods of poor farmers. By closing the Yield Gap agroforestry builds on the advances of the Green Revolution.
Builds on those advances while avoiding its pitfalls, and indeed rectifying its more regrettable consequences, one assumes.
Finally, all this comes together in a set of five ‘Convenient Truths’ which highlight that we have most of the knowledge and skills we need. This is illustrated by the Equator Prize winning project ‘Food for Progress’, in Cameroon, a project which has also been recognized by UK Government’s Office for Science as an African Success Story.
I had a little trouble identifying this project, but I believe I finally found it, and very interesting it sounds too.
Look out for the book in July, from CABI.
