Yes. Absolutely. Plants harbor a myriad of microbes on and within their root tissues. Plant roots aren't simply pipes that suck up water and nutrients - they're plant-soil interfaces that enable plants to do business with soil microbes and establish communication / partnerships with them.
It's why I always recommend gardeners NOT use sterile soil mixes when starting seeds, as many "guides" insist. Plants need an active soil microbiome to thrive. It's why I have a worm bin to provide worm compost for my seedlings - worm poop is rich in soil microbes and nutrients.
