Wageningen researchers throw light on how nitrogen nodules are formed
Dr Rene Geurts has been searching since the 1990s for the mechanism that
gives Rhizobium bacteria entrance to legumes like soya and peas. He
narrowly missed pinpointing it when he published his PhD thesis five years
ago, but now a PhD student of his has helped to uncover the key to the
mystery. Their findings will be published soon in Science.
Everyday sees new publications in the field that PhD candidate Erik Limpens
and Geurts also write about. Not that that is surprising: the relationship
between bacteria like Rhizobium and leguminous plants such as peas and soya
has been crucial to agriculture for thousands of years.
“Legumes can convert nitrogen from the air into ammonia,
