Plant Sensing and Communication

Animals are believed to have learned when past experiences influence future responses. Similarly, plants can be considered to have learned when past events cause chemical changes that alter the sensitivity, speed, or effectiveness of plant sensing and responses. Prior experiences involving light, chemicals, resources, pathogens and herbivores have all been found to affect subsequent plant behaviors. Most examples of plant learning involve rapid and short-lived memory although these are sometimes more durable, lasting the entire life of the individual. Many recent studies also indicate transgenerational effects in which offspring phenotypes are influenced by both their genes as well as the experiences of their parents and earlier ancestors.
