- Effect of various growth regulators on growth of yam (Dioscorea trifida L.) in vitro shoot tips. One small step for yam cryopreservation.
- The USDA Barley Core Collection: Genetic Diversity, Population Structure, and Potential for Genome-Wide Association Studies. 5 sub-populations: roughly, Mediterranean, W Europe, E Europe, Asia and Ethiopia. GWAS effective in locating important phenotypes.
- A first genetic map of date palm (Phoenix dactylifera) reveals long-range genome structure conservation in the palms. Lots of synteny with oil palm and coconut despite differences in genome size. And we now (probably) know how sex determination works.
- Economic evaluation of ecosystem goods and services under different landscape management scenarios. Agriculture usually wins at the expense of more “ecological” land uses, unless income from C and biodiversity (and timber) go up, or discount rates go down.
- Oil in the Sahara: mapping anthropogenic threats to Saharan biodiversity from space. You can spot biodiversity threats from space. More examples along the same lines.
- Genetic and morphological diversity of okra (Abelmoschus esculentus [L.] Moench.) genotypes and their possible relationships, with particular reference to Greek landraces. Much phenotypic variation, less AFLP variation, but geographically structured. Germination characteristics vary with ecology.
- Genetic diversity revealed by EST-SSR markers in carob tree (Ceratonia siliqua L.). First time carbob has been genotyped using microsatellites. And that seems to be the only reason why this work was done.
- Investigation of the genetic diversity of domestic Capra hircus breeds reared within an early goat domestication area in Iran. Breeds are diverse but geographically distinct, the western ones especially. Unlike sheep, which are moved around a lot more. Some evidence of inbreeding, which can and should be counteracted.
- Diversity Assessment and Development of Sustainable Use of Mexican Genetic Resources: Prospects of a SATREPS Project. That would be Science and Technology Research Partnership for Sustainable Development, between the Japanese and Mexican genebanks. Looks like a lot of genotyping and in vitro conservation research on lesser-known crops.
- Establishing the validity of domestication genes using DNA from ancient chickens. You really need ancient DNA to study domestication.
- Genetic diversity and population structure of Mongolian domestic Bactrian camels (Camelus bactrianus). No breeds, no problem.

Pigeon Foot sorghum unmasked
You may remember my quandary over the meaning of the name of the sorghum variety Gadam El Hamam. Well, I had the opportunity of asking real experts at the ICRISAT office in Nairobi yesterday. They confirmed, first of all, that the Gadam sorghum that is being so successfully used in beer brewing in Kenya is indeed a selection from the Sudanese variety Gadam El Hamam. And after a quick email to their Sudanese sorghum breeder colleague based in Addis Ababa, we solved the mystery of the name. It turns out the correct transliteration is Gadam Elhmam, which means “Pigeon Foot” in Arabic. This is apparently a trope that is used in Sudanese poetry and songs to describe a beautiful lady. So I more or less had the bits, but I could not put them together. Thanks to all at ICRISAT in Nairobi for helping me do that at last.
Incidentally, the photo is of a beautiful Faidherbia albida tree on the ICRAF campus in Nairobi, which is where the ICRISAT regional office is housed. You may be able to make out from that the Napier grass and mulberries are taller and more lush just under the tree as compared to further back. They don’t call Faidherbia the cornerstone of “evergreen agriculture” (big PDF) for nothing.
The Queen of Crop Breeding
Yes, I know blogging has been slow the past week or so, but I’ve been on leave and Jeremy way too busy with work for everyone’s good, though mostly his. But look, you got couple of big fat Brainfoods to keep you going, no? 1 Anyway, thought you might be interested in this piece in Kenya’s Saturday Nation newspaper a couple of days back. It’s a profile of AGRA plant breeder Dr Jane Ininda. The illustration is a (poor quality, alas) photo of the actual newspaper, which I took because it was such a treat to see a crop breeder splashed all over a major national newspaper. And the effect is just not the same in the digital version.
