Following yesterday’s promise, here are extinct crop wild relatives mapped. Your job is to match dots to names.
Extinct crop wild relatives
You may have seen coverage of a recent paper in Nature in which Kew researchers quantified the rate of plant extinction over the last 250 or so years. The headline number is about 3 species have been going extinct per year, which is about 500 times the background rate. But I know that what you really want to know is how many of these are crop wild relatives. Well, my friends at CIAT worked their database magic, and came up with the following list of extinct species which are classified by at least one source as a crop wild relative:
Diplotaxis siettiana
Franklinia alatamaha
Helianthus praetermissus
Hutchinsia tasmanica
Ilex gardneriana
Isatis arnoldiana
Lepidium drummondii
Lepidium obtusatum
Mangifera casturi
Musa fitzalanii
Piper collinum
Potentilla multijuga
Rorippa coloradensis
Solanum bauerianum
Solanum cajamarquense
Solanum ruvu
Syzygium balfourii
Syzygium microphyllum
Syzygium palghatense
Which means about 1 per decade or thereabouts. But that, clearly, is just a minimum.
Perhaps I’ll try to map where these plants were last seen.
Free the grasspea
Is there a valid scientific reason for the grasspea (Lathyrus sativus) ban in India? We’ve blogged about this before. Mongabay is now on the case.
The claim that khesari dal can cause lathyrism is increasingly being challenged by researchers who feel that the ban was not based on systemic research over a prolonged period.
So what’s the problem?
Sources in the FSSAI 1 say that the ban has helped people associated with the import of other pulses such as toor dal 2. “In the wake of drop in production of popular pulses ensuing imports, traders lobby is benefitted. (Shortage of pulses in India, increases prices, benefitting traders.) They would never want the ban lifted,” said one official on condition of anonymity.
Meanwhile, research and breeding continue.

- Indigenous Grasses for Rehabilitating Degraded African Drylands. Promising results, but it’s not easy.
- Variability in the Global Proso Millet (Panicum miliaceum L.) Germplasm Collection Conserved at the ICRISAT Genebank. Asian, European and mixed clusters, based on morphology. Out of over 800 accessions, 3 (IPm 2069, IPm 2076 and IPm 2537) are rich in grain Fe, Zn, Ca, and protein.
- Household-specific targeting of agricultural advice via mobile phones: Feasibility of a minimum data approach for smallholder context. A little household data goes a long way. Includes crop diversity info?
- The genome of cowpea (Vigna unguiculata [L.] Walp.). There’s a gene for multiple organ gigantism.
- Reduced response diversity does not negatively impact wheat climate resilience. The suggestion that the statistical methods used were faulty means wheat may not be as in trouble in Europe as a previous paper suggested.
- Evaluating WorldClim Version 1 (1961–1990) as the Baseline for Sustainable Use of Forest and Environmental Resources in a Changing Climate. Maybe not as good as it might be. But what’s the alternative?
- Worldwide phylogeography and history of wheat genetic diversity. Three groups, with one (the Asian genepool) hardly used in breeding.
- Durum Wheat (Triticum durum Desf.): Origin, Cultivation and Potential Expansion in Sub-Saharan Africa. From the Ethiopian highlands and Saharan oases to the mainstream?
- Global mapping of cost‐effective microalgal biofuel production areas with minimal environmental impact. The dry coasts of N and E Africa, the Middle East, and western S America. But how minimal is minimal?
- From women’s empowerment to food security: Revisiting global discourses through a cross-country analysis. The patriarchy is resourceful.
- Genetic association with high‐resolution climate data reveals selection footprints in the genomes of barley landraces across the Iberian Peninsula. Cold temperature, late‐season frost occurrence and water availability have driven landrace genetic differentiation.
