The question is self-describing.
Is there notation denoting that one sigma-algebra is sub-sigma-algebra of another?

I have never seen such a notation, per se. The closest I've seen is something like:
Let $\mathcal{F}, \mathcal{G}$ be $\sigma$-algebras, with $\mathcal{F} \subset \mathcal{G}$.
That is, using $\subset$ (to indicate containment as sets), where it is made clear elsewhere (or from context) that the sets in question are $\sigma$-algebras.
