A life-long love for seeds
The Journal of Tropical Agricultural Sciences has a nice appreciation of the life and career of Prof. Chin Hoong-Fong, who died recently. He was a pioneer of seed conservation research, as the list of selected papers by Prof. Chin included in the tribute makes abundantly clear.
African rice roundup
It struck me that our friends at AfricaRice genebank and their partners have been particularly busy genotyping and phenotyping these past couple of years, so here’s a quick roundup of recent papers on the crop for easy reference.
- The Rise and Fall of African Rice Cultivation Revealed by Analysis of 246 New Genomes
- Genetic control of seed shattering during African rice domestication
- A single-nucleotide polymorphism causes smaller grain size and loss of seed shattering during African rice domestication
- Genetic Variation and Population Structure of Oryza glaberrima and Development of a Mini-Core Collection Using DArTseq

And I’m sure I’m missed a few, these are just the ones that we have included in Brainfoods…
