Brainfood: Ectomycorrhiza, Synthetic peanuts, Ancient Greek amphorae, European bison, Pea breeding, Animal domestication
- Ectomycorrhizas and climate change. One more damn thing to worry about.
- Meiotic analysis of the hybrids between cultivated and synthetic tetraploid groundnuts. It’s normal. The meiosis I mean. Why isn’t this sort of thing done with more crops?
- Aspects of Ancient Greek trade re-evaluated with amphora DNA evidence. More than just wine and olive oil.
- Reconstructing range dynamics and range fragmentation of European bison for the last 8000 years. More eastern and northern than thought, and more affected by the spread of farming than climate change in the Holocene.
- Resistance to downy mildew (Peronospora viciae) in Australian field pea germplasm (Pisum sativum). It comes from Afghanistan.

Banana threat averted? Not quite yet
Strange news from Scidev.net, which reports that:
[R]esults of a field study in Davao City, on the island of Mindanao in the Philippines, show that two Cavendish varieties are highly resistant to Panama disease.
These varieties, he said, were produced in Taiwan by selecting improved mutants from the Cavendish variety.
Why strange? For one thing, because Cavendish bananas have long been resistant to Panama disease. That’s why they are so widespread, because they replaced Gros Michel, the previous dominant variety, which was wiped out commercially by Panama disease in the 1950s and 1960s.
To give credit, Scidev.net explains that the threat is a new form of Panama disease, which is caused by the fungus Fusarium oxysporum, known as Tropical Race 4. Cavendish was resistant to race 1 of Fusarium wilt, to which Gros Michel was susceptible. Tropical Race 4 attacks Cavendish too. But not, according to the report, all Cavendish plants. Some clones, like those ones from Taiwan, are showing resistance.
Strange too because the thrust of the Scidev.net piece is that Filipino scientists are calling on the government to establish a National Research, Development and Extension Center for Banana. But hang on. Tropical Race 4 is a global menace. The very fact that Taiwanese selections are showing promise on Mindanao in the Philippines should give pause.
Wouldn’t it be much more efficient for all governments in the region and beyond to contribute to a global effort? The big banana concerns were to some extent to blame for the demise of Gros Michel and the march of Panama disease, as they abandoned infected plantations and brought new areas into cultivation until there was nowhere left to run and they had to switch. This time around, they could support a globally co-ordinated effort to find and distribute more resistant varieties.
