Exploring legume nodulation in the deepest reaches of the Amazon

Exploring legume nodulation in the deepest reaches of the Amazon

"We are trying to build up a pattern of how nodulation evolved in these more primitive and mainly tree relatives of the advanced crops peas and beans in order to see how we might engineer a simple symbiosis into maize"
The expedition focussed on an area around the Rio Cuieiras in the Amazon region

An international effort to develop maize crops that don’t need fertiliser has taken Hutton scientist Euan James to the deepest reaches of the Amazon River, on a quest for samples of root nodules from legume trees to help understand how these plants were able to develop the ability to obtain their own nitrogen from soil – and whether this trait can be transferred to other crops.
