AFAIK, no, it doesn't; the component which has root is part of the operating system image, and the Play Store merely has the permissions to tell that component to silently install or upgrade a package. However, when upgrading a package, that component will only allow the upgrade if the package is signed by the same key as the previous release. This has more than once led to a package no longer being able to be updated, because the developer was not careful enough with backups and lost the private key.
