Brainfood: Tomato diversity, Tomato characterization, Sweetpotato diversity, Olive characterization, Bamboo as fodder, Chinese liquor, Agroecological livestock, Oasis agrobiodiversity, Pearl millet diversity double
- Genomic variation in tomato, from wild ancestors to contemporary breeding accessions. A first domestication in South America, a second step in Mesoamerica, occasional hybridization in the wild, differentiation through human selection. Some Ecuadorian and Peruvian diversity still unexplored for breeding.
- Characterization of a collection of local varieties of tomato (Solanum lycopersicum L.) using conventional descriptors and the high-throughput phenomics tool Tomato Analyzer. Instant gratification comes to tomato characterization.
- Molecular diversity and genetic structure of 380 sweetpotato accessions as revealed by SSR markers. Also a two-step domestication history? What are the odds?
- Association of SSR markers with contents of fatty acids in olive oil and genetic diversity analysis of an olive core collection. Let the molecular-assisted breeding begin.

- Farm animal genetic and genomic resources from an agroecological perspective. If you’re going to really be ecological in your management of livestock genetic resources, you need to factor in ecosystem services, and figure out how genomic tools are going to help you. Well, that pretty much goes for crops too, surely.

All sweetpotatoes are transgenic
Tina Kyndta and collaborators ((Kyndt T, Quispe D, Zhai H, Jarret R, Ghislain M, Liu Q, Gheysen G, & Kreuze JF (2015). The genome of cultivated sweet potato contains Agrobacterium T-DNAs with expressed genes: An example of a naturally transgenic food crop. Proceedings of the National Academy of Sciences of the United States of America PMID: 25902487)) have found that all cultivated sweetpotatoes are naturally transgenic because they contain transfer DNA (T-DNA) sequences from Agrobacterium. Gene-transfer via Agrobacterium is a naturally occurring process, that is used to make genetically modified crops in the lab. We did not know that one of our main food crops was once naturally transformed via the same process.
Kyndta et al. did not find any T-DNA in the wild relatives of sweetpotato, suggesting that the transformation(s) provided a beneficial trait that was selected for during domestication. The introduced genes are intact and expressed in different organs of the “Huachano” variety that they studied in detail, but we’ll have to wait for future expression studies to find out about the benefit of these paleo-GMOs.
The authors also suggest that, as people have been eating these swollen roots for millennia, we might now consider all transgenic crops to be “natural”. I don’t know about that. Didn’t most of these people suffer and die young? I predict that sweetpotato consumption will plummet now that the word is out.
