Researchers at the University of Maryland (UMD) have discovered an entirely new role for a well-known plant molecule called ACC, providing the first clear example of ACC acting on its own as a likely plant hormone. Just like in humans and animals, hormones in plants carry messages to signal and trigger essential processes for plant health and functionality, from reproduction to defense. Without these processes, crops can’t reproduce and thrive to provide the food we need to feed a growing global population. In a new publication in Nature Communications, researchers show that ACC has a critical role in pollination and seed production by activating proteins similar to those involved in nervous system responses in humans and animals. These findings could not only change textbooks that have previously attributed plant responses to the hormone ethylene instead of ACC, but could also open the door for new research to improve plant health and crop yield.
