What can possibly go wrong?: The risks of introducing soil microorganisms from Antarctica into South America

Endophytic fungi form mutualistic associations with plant roots which can increase plant survival and resistance to stress. Recently, it has been proposed that endophytic fungi from Antarctica should be used to facilitate reintroduction and establishment of native plants in xeric environments of nor...
