Schematic representation of predominant events that characterize the endophytic interaction between diazotrophic bacteria and plant host: (1) chemotaxis from soil to rhizosphere; (2) attachment on plant root surface; (3) development of aggregates or biofilms; (4) lateral root cracks as main infection point and (5) apoplastic spread and endophytic colonization. Followed by how the application of humic acid combined with endophytic diazotrophic bacteria could modulate different steps of the biological interaction that results in increased epiphytic and endophytic population associated to the host plant
