Composition of cucumber (Cucumis sativus) seed- and root-colonizing bacterial (a) and Oxalobacteraceae community (b), based on 454-pyrosequencing of general bacterial 16S rRNA gene fragments.
Sequences were obtained from samples of seeds (1 day) and roots (2, 7 and 21 days old) grown in perlite and compost-amended perlite, with and without inoculation with Pythium aphanidermatum (1day only). Numbers indicate the relative abundance of the indicated taxon (% of total bacteria). Families for which relative abundance was ≥1% are included in panel a.
