FIG. 5.
Specific probes hybridize to cells in aggregates in Corticium sp. embryos. CY3-labeled probes specific for the alphaproteobacterium CC01 (A), the actinobacterium CC07 (B), and the clade SpC1 (C) hybridize to cells (arrowheads) in the aggregates in the embryos. Single-base-mismatch probes, negative controls testing probe specificity, do not hybridize to cells in the bacterial aggregates (lines) in the embryos (D, E, and F).
