- Phylogenetic analysis in some Hordeum species (Triticeae; Poaceae) based on two single-copy nuclear genes encoding acetyl-CoA carboxylase. Divides up the Africa/Asia and American clades, but not perfectly.
- Journeys through aroma space: a novel approach towards the selection of aroma-enriched strawberry cultivars in breeding programmes. Breed a better smelling strawberry in this way, and the world will beat a path to your door.
- Strategies for engineering C4 photosynthesis. More than one way to skin a cat. But is it worth doing if you don’t eat cats?
- Uses of tree saps in northern and eastern parts of Europe. Not what it used to be.
- Resequencing rice genomes: an emerging new era of rice genomics. Maybe. But it would have been better if they had sequenced something other than Nipponbare originally.
- Toward conservational anthropology: addressing anthropocentric bias in anthropology. “Traditional practices” not always all that great.
- Seed exchange networks for agrobiodiversity conservation. A review. Farmers have to be “well connected” for conservation to work. But nobody really knows what that means.
- Landscape diversity and the resilience of agricultural returns: a portfolio analysis of land-use patterns and economic returns from lowland agriculture. Higher gross margin related positively to greater variance, negatively to diversity, in lowland UK, up to 12000 ha.
- Marker-assisted development and characterization of a set of Triticum aestivum lines carrying different introgressions from the T. timopheevii genome. Getting resistance out of wild relatives and into crops.
- Physical localization of a novel blue-grained gene derived from Thinopyrum bessarabicum. Getting blue pigments out of a wild relative and into wheat.
- Improvement of two traditional Basmati rice varieties for bacterial blight resistance and plant stature through morphological and marker-assisted selection. Getting blight resistance out of an improved variety to improve traditional ones.

- Higher levels of multiple ecosystem services are found in forests with more tree species. Swedish production forests, anyway. And more. And more.
PAGxxi tweetstorm of sorts
PAGxxi, billed as “The Largest Ag-Genomics Meeting in the World” is off and running in San Diego, with its full complement of social media bells and whistles. I’m quite enjoying the Twitter feed. Not the official one, mind you, which is pretty boring, but there’s a half a dozen or so people (so far) who are taking the hashtag very seriously. I hope they keep it up.

Yes, we have many solutions
IITA has a pretty nice video out about controlling Banana Xanthomonas Wilt via genetic modification.
Now, don’t jump to any conclusions, I have nothing against genetic modification of banana. In fact, if you’re going to use genetic modification on anything, bananas should be right up there. No chance of that pesky transgene escaping into the wild, for a start. Although I would like to know how they’re planning to engineer resistance into the dozens of varieties that are important in East Africa. Wait, you mean they’re not going to do that? Just a few, eh?
Well, anyway. My main point is that the video gives no hint at all that, as far as BXW control is concerned at any rate, there are other, perfectly viable, options. And IITA knows this, because it has been involved in the development of a pretty effective, multi-faceted, low-cost, integrated, sustainable strategy for control. One that doesn’t involve the threat of reducing the diversity of the crop.
Of course, it would help if there were similarly nice videos about that. There are factsheets galore, true. Lots of factsheets. But videos? Well, maybe you can get them to work. And anyway they don’t really seem to be aimed at the general audience so clearly targeted by IITA’s vid. How can we make the case that there are occasionally more appropriate, sustainable solutions than GMOs when we can’t even win the battle of the videos?
Brainfood: Climate in Cameroon, Payments for Conservation, Finger Millet, GWAS, Populus genome, miRNA, C4, Cadastres, Orange maize, Raised beds, Contingent valuation, Wild edibles, Sorghum genomics, Brazilian PGR, Citrus genomics
- Climate and Food Production: Understanding Vulnerability from Past Trends in Africa’s Sudan-Sahel. Investment in smallholder farmers can reduce vulnerability, it says here.
- An evaluation of the effectiveness of a direct payment for biodiversity conservation: The Bird Nest Protection Program in the Northern Plains of Cambodia. It works, if you get it right; now can we see some more for agricultural biodiversity?
- Finger millet: the contribution of vernacular names towards its prehistory. You wouldn’t believe how many different names there are, or how they illuminate its spread.
- Genome-Wide Association Studies. How to do them. You need a platform with that?
- Revisiting the sequencing of the first tree genome: Populus trichocarpa. Why to do them.
- Exogenous plant MIR168a specifically targets mammalian LDLRAP1: evidence of cross-kingdom regulation by microRNA. “…exogenous plant miRNAs in food can regulate the expression of target genes in mammals.” Nuff said. We just don’t understand how this regulation business works, do we.
- Anatomical enablers and the evolution of C4 photosynthesis in grasses. It’s the size of the vascular bundle sheath, stupid!
- Land administration for food security: A research synthesis. Administration meaning registration, basically. Can be good for smallholders, via securing tenure, at least in theory. Governments like it for other reasons, of course. However you slice it, though, the GIS jockeys need to get out more.
- Genetic Analysis of Visually Scored Orange Kernel Color in Maize. It’s better than yellow.
- Comment on “Ecological engineers ahead of their time: The functioning of pre-Columbian raised-field agriculture and its potential contributions to sustainability today” by Dephine Renard et al. Back to the future. Not.
- Environmental stratifications as the basis for national, European and global ecological monitoring. Bet it wouldn’t take much to apply it to agroecosystems for agrobiodiversity monitoring.
- Use of Contingent Valuation to Assess Farmer Preference for On-farm Conservation of Minor Millets: Case from South India. Fancy maths suggests farmers willing to receive money to grow crops.
- Wild food plant use in 21st century Europe: the disappearance of old traditions and the search for new cuisines involving wild edibles. The future is Noma.
- Population genomic and genome-wide association studies of agroclimatic traits in sorghum. Structuring by morphological race, and geography within races. Domestication genes confirmed. Promise of food for all held out.
- Response of Sorghum to Abiotic Stresses: A Review. Ok, it could be kinda bad, but now we have the above, don’t we.
- Genetic resources: the basis for sustainable and competitive plant breeding. In Brazil, that is.
- A nuclear phylogenetic analysis: SNPs, indels and SSRs deliver new insights into the relationships in the ‘true citrus fruit trees’ group (Citrinae, Rutaceae) and the origin of cultivated species. SNPs better than SSRs in telling taxa apart. Results consistent with taxonomic subdivisions and geographic origin of taxa. Some biochemical pathway and salt resistance genes showing positive selection. No doubt this will soon lead to tasty, nutritious varieties that can grow on beaches.
Brainfood: Pig genome, Turkey genome, Big genomes, Maize genome, Potato improvement, Mango diversity, Coconut germination
- Analyses of pig genomes provide insight into porcine demography and evolution. More wild diversity in Asia, suggesting origin there, followed by migration to Europe. Separate domestication in SE Asia and Europe, followed by geneflow.
- Whole genome SNP discovery and analysis of genetic diversity in Turkey (Meleagris gallopavo). Lot less diverse than chicken. Or pig. Commercial breed even less diverse.
- Why size really matters when sequencing plant genomes. We must not shy away from the big genomes.
- QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance. Eureka!
- Crops that feed the world 8: Potato: are the trends of increased global production sustainable? Maybe. But can you guess what will be needed? Nice review of genebank holdings and improvement strategies and aims.
- Physico-chemical Characterization of Unexploited Mango Diversity in Sub-mountane Zone of Northern India. 28 varieties in the Punjab, with all kinds of different uses.
- Germination Rate is the Significant Characteristic Determining Coconut Palm Diversity. Natural and artificial selection associated with different rates of germination (as well as other phenotypic traits of course).
