- Molecular Markers for Genetic Diversity Studies in African Leafy Vegetables. Not surprisingly, only 3% of 33 studies since 1998 are on Cleome, more than half on cowpea. And a quarter used RAPDs. Orphan crops, anyone? These one don’t even get a table summarizing and comparing findings across species.
- Conservation priorities of Iberoamerican pig breeds and their ancestors based on microsatellite information. Depending on how you crunch the genetic numbers, Iberoamerican pig breeds could conceivably best be looked after by conserving their ancestral Iberian pig breeds. But it’s not just about the genetics, is it?
- Native fruit tree genetic resources in Japan. Only a Castanea was domesticated in pre-modern times, and they’re all endangered in post-modern times.
- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. It’s seedlings that look most like existing varieties that farmers try to keep.
- Changes in sunflower breeding over the last fifty years. From yield under optimal conditions to disease resistance, from oil quantity to quality. But international collaboration still needed.
- Angolan vegetable crops have unique genotypes of potential value for future breeding programmes. Unique material documented, and hopefully made available for use.

Measuring the elements of sorghum
There’s a great photo on the cover of Plant Physiology this month.
The paper in question looks at the “ionome” of sorghum seeds. That’s a new one on me too. It’s the genes responsible for the accumulation of different elements in whatever tissue. The authors measured the levels of a whole suite of elements in the seeds of a carefully chosen set of very diverse, and equally carefully genotyped, sorghum accessions representing all races. By comparing phenotype with genoptype, they identified gene variants associated with high levels of zinc, manganese, nickel, calcium, and cadmium. Now breeders interested in biofortification know what to include in their crossing programs.
