Abstract
A strain of Serratia sp. Ent16 isolated from internal tissues of pea nodule inhibited in vitro growth of the plant pathogens Fusarium oxysporum and Bipolaris sorokiniana and the model strain Rhizobium leguminosarum bv viceae 1078 but had a considerably weaker antagonistic effect on the Rhizobium strain Rh16 from its own nodule. Cells of the Ent16 strain tagged by the gfp gene (the Ent16-gfp strain) were not seen in the pea endorhizosphere when plants were grown in a rich culture medium. The development of symbiosis was favored by plant germination on filter paper. Confocal microscopy showed that individual cells of the Ent16-gfp strain were attached to the outer side of root hair cell walls, while agglomerations of fluorescent bacterial cells were detected in the zone of exoderm of lateral root formation and in root vessels. A series of scanned sections of pea root revealed the presence of the Ent16-gfp strain in lateral root primordia, through which the bacteria penetrated the endorhizosphere.
