I am not an astronaut myself, but hopefully there will be other people in the future who can go to Mars for long-term missions. In that case, they need a life support system in which to grow food, create an atmosphere and recycle wastewater. Plants could provide all those things, so yes, it makes sense to use plants in long-term life support systems on other planets.
Before this happens, researchers first want to find out if life is already there. For example the ExoMars Rover will be launched in a few years’ time, and hopefully that mission will teach us more about if there is life on Mars right now, or if there has been in the past.
