In addition, not read this paper but it's high on my to-do list: "Learning by Association in Plants" extract of abstract: "the possibility that plants are also able to acquire learned associations to guide their foraging behaviour has never been demonstrated. Here we show that this type of learning occurs in the garden pea, Pisum sativum. By using a Y-maze task, we show that the position of a neutral cue, predicting the location of a light source, affected the direction of plant growth. This learned behaviour prevailed over innate phototropism" https://www.nature.com/articles/srep38427 https://www.nature.com/articles/srep38427 Incredible, if validated.
