Giving wheat breeders something to really cheer about
Nice to see a story about germplasm evaluation by a genebank make it into the mainstream media in India.
In what is claimed to be the first global mega study, Indian agricultural scientists screened about 20,000 accessions of wheat germplasm conserved in the country’s gene bank to identify genes that can confer resistance against all types of fungal diseases affecting cereal grain grown worldwide.
But why now? The paper to which the story refers came out in December last year, and we included it in a Brainfoond in January. And, more importantly, why are the data not available on NBPGR’s Data Portal?
Brainfood: Antioxidant adzuki, Sorghum gaps, Natural rubber diversity, Non-flying geese
- Phytochemical distribution and antioxidant activities of Korean adzuki bean (Vigna angularis) landraces. A cluster of about 10% of 200 Korean landraces have higher antioxidant activity, and smaller seeds. Watch them take over the world.
- Sorghum germplasm from West and Central Africa maintained in the ICRISAT genebank: Status, gaps, and diversity. Lots of gaps, but Nigeria isn’t one of them.
- A century of guayule: Comprehensive genetic characterization of the US national guayule (Parthenium argentatum A. Gray) germplasm collection. The future of natural rubber is in Texas.
- Contribution of both positive selection and relaxation of selective constraints to degeneration of flyability during geese domestication. Wild geese chased no longer due to strong selection on mitochondrial respiratory chain genes.
Brainfood: Hot seeds, Diet diversity double, Finger millet GxE, Botanical gardens, CWR prebreeding double, Pathogen spread, Dog genomics, Cryo calculations, Biodiversity & productivity double, Movies & conservation
- High-temperature stress during drying improves subsequent rice (Oryza sativa L.) seed longevity. Up to 45°C, because it triggers a stress protection mechanism.

- Ex situ conservation of plant diversity in the world’s botanic gardens. A third of all known plants, and half of endangered ones, are to be found in botanic gardens, but the tropics are under-represented.
- Prebreeding Using Wild Species for Genetic Enhancement of Grain Legumes at ICRISAT. It’s a drag, but someone has to do it.
- Wide crosses of durum wheat (Triticum durum Desf.) reveal good disease resistance, yield stability, and industrial quality across Mediterranean sites. Not such a drag after all.
- Quantifying airborne dispersal routes of pathogens over continents to safeguard global wheat supply. Incredibly fancy maths says Yemen is the key.
- Demographic history, selection and functional diversity of the canine genome. There’s a lot here, in particular the genes that were involved in early phenotypic differentiation from wolves, and evidence of continuous geneflow with wilds canids. But the thing that really got me is that humans and dogs show parallel evolution in the ability to process complex carbohydrates, associated with agriculture.

- Biodiversity effects in the wild are common and as strong as key drivers of productivity. Meta-analysis of observations in nature supports results of experimental work.
- Biodiversity promotes primary productivity and growing season lengthening at the landscape scale. “…a large species pool is important for adaption to climate change.” An example of the above.
- Considering connections between Hollywood and biodiversity conservation. Conservationists need to get out more.
