Inhibiting biological nitrification in elite wheat
Many thanks to Victor Kommerell for pointing me to a new paper representing a sort of culmination of work that we first blogged about back in 2007. The older paper posed a question in its title: Can biological nitrification inhibition (BNI) genes from perennial Leymus racemosus (Triticeae) combat nitrification in wheat farming? The answer now seems to be a resounding maybe.
Smallholder access to seeds in Africa benchmarked
You’ll remember that the good people at Access to Seeds Index rate seed companies on how and to what extent they make their products available to smallholder farmer in developing countries. Today they launched the results for 32 companies working in Western and Central Africa. Here are the key findings (I’m quoting):
- Seed companies are active in almost all index countries across Sub-Saharan Africa and South and South-east Asia.
- Many companies are providing more diverse portfolios for vegetables and field crops but need to offer more pulses to help tackle malnutrition.
- Leading seed companies are offering extension services in more countries.
- Companies are still only concentrating their investments in infrastructure in a few countries.
But you want to know who did well in the rankings, right? Ok, here’s the Top 3.
Well done, Bayer, East-West and Novalliance.

- Food systems: seven priorities to end hunger and protect the planet. Oh good, includes “Biodiversity and genetic bases need to be protected. Seed varieties must be preserved, and their phenotypes and genotypes explored in the contexts of climate change and nutrition. Traditional food and forest systems, including those of Indigenous peoples, need to be better understood and supported in national agricultural research systems.” Phew.
- Future Changes in Wet and Dry Season Characteristics in CMIP5 and CMIP6 Simulations. The above is just as well because longer hotter and drier spells are coming to the tropics, and crops will suffer.
- Global assessment of the impacts of COVID-19 on food security. Plus there’s this too. Resilience has a cost.
- The future of farming: Who will produce our food? Smallholders…
- When agriculture drives development: Lessons from the Green Revolution. …and that may be bad.
- Ok, the above two entries need unpacking. The second paper shows that the “agricultural engine of growth” was totally a thing during the Green Revolution, but the first that it now appears to be broken.
- Extinction risk of Mesoamerican crop wild relatives. Oh no, on top of everything else, we might lose avocados and vanilla.
- Determinants of Smallholder Maintenance of Crop Diversity in Morocco’s High Atlas Mountains. Markets, land and water. So what would any new Green Revolution do to diversity? Have we learned anything?
- Landscape complexity and US crop production. …are positively correlated. For Morocco too, I wonder?
- Utilize existing genetic diversity before genetic modification in indigenous crops. At least in Ethiopia.
- Compulsion and reactance: Why do some green consumers fail to follow through with planned environmental behaviors? Because some believe in technology, and other is abstinence. Which means they need different messages to encourage them to put their money where their mouths are. Would it work in Ethiopia?
Featured: Breeding with wild peanuts
David Bertioli points out, in a comment to a blog post about a recent paper of his, that there’s more than one way to use peanut wild relatives in breeding:
Your previous blog detailed the impact of Charles Simpson’s crosses in Texas, which used the “tetraploid route” of introgression which donated a chromosome segment from A09 which confers root knot nematode resistance. The PNAS paper focuses mostly on progeny from the North Carolina “hexaploid route”, which ended up traveling most around the world. These introgressions, from A02 and A03, confer resistance to Late Leaf Spot, Rust, and to a lesser extent Web Blotch.
Would be interesting to compare the impacts of the two “routes.”
