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.

- The preservation of genetic resources of the vine requires cohabitation between institutional clonal selection, mass selection and private clonal selection. Intra-varietal diversity, that is. They apparently do it best in Portugal.
- Association of dwarfism and floral induction with a grape ‘green revolution’ mutation. Cool things I learned from this paper: 1. Pinot Meunier is a periclinal mutant. 2. Tendrils are inflorescences. 3. Dwarf grapes are dwarf for the same reason dwarf wheat is dwarf. No word on what the Portuguese are doing about it. And the fact that the paper is over 10 years old is irrelevant to its coolness.
- Quantifying the impacts of ecological restoration on biodiversity and ecosystem services in agroecosystems: A global meta-analysis. Supporting ecosystem services go up 40% on average, regulating ES by 120%. Well worth having.
- Can a Botanic Garden Cycad Collection Capture the Genetic Diversity in a Wild Population? Yes, but need to “(1) use the species biology to inform the collecting strategy; (2) manage each population separately; (3) collect and maintain multiple accessions; and (4) collect over multiple years.” Maybe they should talk to the Xishuangbanna Tropical Botanical Garden guys.
- Genebanking Seeds from Natural Populations. It’s more difficult than with crops. And then you’ve got the above.
- Genomics-assisted breeding for boosting crop improvement in pigeonpea (Cajanus cajan). “…pigeonpea has become a genomic resources-rich crop and efforts have already been initiated to integrate these resources in pigeonpea breeding.” And now we wait.
- Crop wild relatives of pigeonpea [Cajanus cajan (L.) Millsp.]: Distributions, ex situ conservation status, and potential genetic resources for abiotic stress tolerance. 15 of them need collecting. And, presumably, genotyping (see above).

- Community Perspectives on the On-Farm Diversity of Six Major Cereals and Climate Change in Bhutan. About 30% of varieties lost over last 20 years. But what does it mean that “93% of the respondents manage and use agro-biodiversity for household food security and livelihood”? What exactly does that other 7% of farmers do?
