Female Ferns Can Turn Their Neighbors Male
They communicate with one another to decide gender
‘A combined team of researchers from Nagoya University and the University of Tokyo has discovered that a certain type of fern plant communicates with others of its kind using pheromones as a means of choosing the gender of maturing plants.
