How plants distinguish beneficial from harmful microbes – Science Daily

Legume plants fix atmospheric nitrogen with the help of symbiotic bacteria, called Rhizobia, which colonize their roots. Therefore, plants have to be able to precisely recognize their symbiont to avoid infection by pathogenic microbes. To this end, legumes use different LysM receptor proteins located on the outer cell surface of their roots. In the study published in Science, an international team of researchers led by Aarhus University show that pathogenic (chitin) or symbiotic signalling molec…
