Plants fix nitrogen in common parlance but you are technically correct: I sincerely hope that your scientific pedantry works out better for you than it has for me (I won't delve into that topic further).

The research was specifically about introducing nitrogen-fixing organelles into plants because they have none. Precision is valuable since this was in direct contradiction to the original topic. Maybe common parlance is better-suited to a thread on vegetable gardening than microbiology.
