Bruce McClure studies plant mating. Similarly to all sexually reproducing organisms, plants devise ways to identify appropriate mates. The penalty for choosing a partner who is either too closely related or too genetically different is unhealthy offspring. Sound familiar? The same rules apply to human reproduction, with one major difference—plants can’t move around or talk. McClure and his fellow researchers approach plant mating with a scientific lens and study the type of communication that takes place within these organisms.
