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.

- 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.

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.
Brainfood: Ag vs biodiversity, Bioinformatics, Genomic association, Diversity and productivity in forests, Increasing diversity
- Land, Food, and Biodiversity. Agriculture will expand, but that is bad for biodiversity. It probably must expand, actually, but this can be kept to a minimum by addressing land-use planning, governance and law enforcement, productivity, and market drivers. Oil palm as an example.
- Time to change how we describe biodiversity. By finally tackling the digitization of phenome annotations, apparently. NiM ((Not in Mendeley.))
- Genomic and metabolic prediction of complex heterotic traits in hybrid maize. Amazingly, genotype (SNP) can predict phenotype (biomass traits) pretty well. But in a population where a bunch of dents were crossed with a couple of testers. Will it work with a diverse genebank collection of landraces?
- Forest productivity increases with evenness, species richness and trait variation: a global meta-analysis. In over 50 studies, polycultures come out about 24% better than monocultures, with evenness having more of an effect than richness. Much more commentary and context at ConservationBytes.com. Compare with that recent drylands diversity and ecosystem function paper.
- All Is Not Loss: Plant Biodiversity in the Anthropocene. A model says there have been “gains in exotics caused by species invasions and the introduction of agricultural domesticates and ornamental exotic plants”. Oooh! Contrarian!

- ILRI says we need to maintain indigenous farm animal diversity in Asia. They eat dogs, don’t they?
- You say pomato, I say totato: “Tomato-potato cross benefits farmers.” Fine, but it’s a graft. So why call it a cross?
- Non timber forest products important “in times of crisis” shock.
