FIG 3.

Current situation of culturability in plant endosphere. The scheme indicates the results of this bibliographic study that investigated the taxonomy of culturable endophytes associated to a wide range of plants, and considered different information, i.e., plant compartment, isolation medium, soil type, and plant growing condition. Data elaboration indicates the presence of both a recurrent set of cultured bacterial genera and a wide range of bacterial genera that are rarely isolated under laboratory conditions, revealing the pivotal role of culturomics for the future studies on plant microbiome.
