Abstract
In
this work we analyzed the composition and structure of cultivable
bacterial communities isolated from the stem/leaf and root compartments
of two medicinal plants,
Echinacea purpurea (L.) Moench and Echinacea angustifolia (DC.) Hell,
grown in the same soil, as well as the bacterial community from their
rhizospheric soils. Molecular PCR-based techniques were applied to
cultivable bacteria isolated from the three compartments of the two
plants. The results showed that the two plants and their respective
compartments were characterized by different communities, indicating a
low degree of strain sharing and a strong selective pressure within
plant tissues. Pseudomonas was the most highly represented genus,
together with Actinobacteria and Bacillus spp. The presence of distinct
bacterial communities in different plant species and among compartments
of the same plant species could account for the differences in the
medicinal properties of the two plants. [Int Microbiol 2014;
