Scientists at the John Innes Centre have identified a mechanism that makes plant roots more attractive to soil microbes, potentially leading to crops that require fewer synthetic fertilizers. This breakthrough addresses ecological issues linked to excessive fertilizer use, such as soil degradation and water pollution from nutrient run-offs. The research focused on a mutation in Medicago truncatula that boosts beneficial relationships with bacteria and fungi supplying essential nutrients. Crucially, this discovery also applies to wheat, paving the way for varieties that effectively utilize soil microbes to enhance nutrient absorption and minimize fertilizer dependence.
Researchers at the John Innes Centre have discovered a biological mechanism that enhances plant root interactions with soil microbes, potentially reducing the need for artificial fertilizers.
The research has unveiled insights into endosymbiosis, revealing how some plants can scavenge nutrients more effectively from soil due to beneficial associations with microbes.
