Apr 01, 2011Many researchers have reported that some soil bacteria are specifically associated with AMF; for example, Bianciotto (1996) showed that soil microorganisms can directly or indirectly interact with AMF via the exudates the latter released into soil. AMF exudates were also shown to influence the vitality of soil bacteria (Toljander et al., 2007).
