For two hybrid nanotube systems of (10,10) tubes which contain respectively
a finite capped (5,5) tube (capsule) and a long chain of C$_{60}$`s,
we study electron transport numerically and analytically.
We find that the structural symmetries give distinguishable features to
transmission.
For the (10,10) tube containing the (5,5) capsule, antiresonances occur
by the contribution of additional channels of the (5,5) capsule. The presence
of mirror symmetries in cross sections cause symmetric lineshapes, while
the mirror symmetry breaking leads asymmetric lineshapes.
On the other hand, for the (10,10) tube containing the C$_{60}$ chain,
transmissions present the features such as antiresonance, resonance, and
transmission gap which depend on the mirror symmetries and the rotational
symmetries in the cross sections. These results come from the fact that
the structural symmetries determine the state-mixing of the inner structures
and the outer tubes.
