I searched around and found that "utility patents" are basically the default type of patent (as opposed to design patents or plant patents). Also, contrary to what the above passage might suggest, utility patents expire after 20 years, so it's not like companies will have a perpetual license over a particular trait. Finally, it's unclear how tightly scoped a "trait" has to be in the current patent regime. I would agree that exclusive rights for "heat tolerant broccoli" would be bad for innovation, because it prevents other companies from trying to developing other ways of heat resistance. However, I don't see anything wrong with granting exclusive rights to "heat tolerant broccoli broccoli by modifying this particular gene". Given how bad the Guardian article is with other parts of patent law, I'm somewhat skeptical of their implication that you can patent entire functional categories.
