- Screening old peppers (Capsicum spp.) for disease resistance and pungency-related traits. Resistance does not correlate with geography within an Andean collection.
- Bioactive Compound Variability in a Brazilian Capsicum Pepper Collection. No accession is high in everything.
- Genetic evidence from mitochondrial DNA corroborates the origin of Tibetan chickens. That is, the surrounding regions.
- Morphological and genetic diversity analysis of Citrullus landraces from India and their genetic inter relationship with continental watermelons. Modern cultivars are homogeneous.
- Molecular diversity of sunflower populations maintained as genetic resources is affected by multiplication processes and breeding for major traits. Multiplication slightly reduces within-accession diversity. Well, in France anyway.
- Past and Future Use of Wild Relatives in Crop Breeding. Yada yada.
- Subsistence mosaics, forager-farmer interactions, and the transition to food production in eastern Africa. The transition to agriculture in E Africa was more than just the Bantu expansion.
- Persistent effects of pre-Columbian plant domestication on Amazonian forest composition. Domesticated species are more common around archaeological sites. Sounds like agriculture is not much more than the Arawakan and Tupí expansions.
- Human population growth offsets climate-driven increase in woody vegetation in sub-Saharan Africa. In some places climate change has positive effects, but these are swamped where there is high population growth.

Sweet day
On this fine day, meet Dr Janaki Ammal…
By manipulating polyploid cells through cross-breeding of hybrids in the laboratory, Janaki was able to create a high yielding strain of the sugarcane that would thrive in Indian conditions. Her research also helped analyse the geographical distribution of sugarcane across India, and to establish that the S. Spontaneum variety of sugarcane had originated in India.
…India’s first woman PhD in botany, and a pioneer in the use of wild relatives in sugarcane breeding.
An incredible woman who spent her life in the pursuit of science, Janaki Ammal believed that it was through her work that she should be remembered. So, the next time you use a spoonful of sugar grown by an Indian sugarcane farmer, remember that you are it was Dr Janaki Ammal who added that extra bit of sweetness!
Brainfood: Arabidopsis refugia, Potato diversity, Palm uses, Coffee phylogeny, Traditional harvesting, Buckwheat trends, Maize double haploids, African cattle, Endophenotype
- On the post-glacial spread of human commensal Arabidopsis thaliana. A bit like Neanderthals.
- Exploration of the genetic diversity of cultivated potato and its wild progenitors (Solanum sect. Petota) with insights into potato domestication and genome evolution. Elite cultivars are a pretty diverse lot.
- Fundamental species traits explain provisioning services of tropical American palms. Bigger, more widespread species are more important to local people. Which means some useful things may be being missed.
- Genotyping-by-sequencing provides the first well-resolved phylogeny for coffee (Coffea) and insights into the evolution of caffeine content in its species: GBS coffee phylogeny and the evolution of caffeine content. Origin of the genus could be Africa. Or Asia. Or the Arabian Peninsula. So that narrows it down.
- A quiet harvest: linkage between ritual, seed selection and the historical use of the finger-bladed knife as a traditional plant breeding tool in Ifugao, Philippines. People kept old harvesting technology because it helped them show due reverence to the rice plant, and select seeds.
- Old Crop, New Society: Persistence and Change of Tartary Buckwheat Farming in Yunnan, China. It’s going down, but won’t disappear. No word on what’s happening to diversity though.

- The Importance of Endophenotypes to Evaluate the Relationship between Genotype and External Phenotype. Oh for pity’s sake, something else to worry about.
