Fluorescent Mimosa pudica plants reacting to touch reveals how they avoid predators

Mimosa pudica, known as touch-me-not plants, quickly move their leaves in response to touch and new research reveals how they do it. In a study led by Masatsugu Toyota at Saitama University in Japan, a transgenic fluorescent plant was created that allowed the team to track the movement of calcium signals across the plant’s cells. When touched, fluorescence travelled rapidly through the leaves, triggering their movement. This supports the idea that calcium acts as a long-distance signalling molecule in the plant. It is thought that the reaction helps protect the plant from predation. In the study, grasshoppers were more likely to eat plants rendered unable to move than ones that reacted to touch. -- Subscribe ➤ https://bit.ly/NSYTSUBS Get more from New Scientist: Official website: https://bit.ly/NSYTHP Facebook: https://bit.ly/NSYTFB Twitter: https://bit.ly/NSYTTW Instagram: https://bit.ly/NSYTINSTA LinkedIn: https://bit.ly/NSYTLIN About New Scientist: New Scientist was founded in 1956 for “all those interested in scientific discovery and its social consequences”.
