  The topological nodal-line semimetals (NLSMs) possess a loop of Dirac nodes
in the k space with linear dispersion, different from the point nodes in
Dirac/Weyl semimetals. While the quantum transport associated with the
topologically nontrivial Dirac fermions has been investigated extensively,
features uniquely associated with the extended nodal lines remain to be
demonstrated. Here, we investigate the quantum oscillations (QOs) in the
nodal-line semimetal ZrSiS, with the electron transport along the c axis, and
magnetic field rotating in the ab plane. The extremal orbits identified through
the field orientation dependence of the QOs interlock with the nodal line,
leading to a nonzero Berry phase. Most importantly, the Berry phase shows a
significant dependence on the magnetic field orientation, which we argue to be
due to the finite spin-orbit coupling gap. Our results demonstrate the
importance of the spin-orbit coupling and the nodal-line dispersion in
understanding the quantum transport of NLSMs.
