New research has found when plant leaves physically touch each other, they seem to form a biological signalling network to ...

When plants face stress, they activate a signaling cascade involving multiple molecules like hydrogen peroxide and plant hormones such as salicylic acid, leading to resistance or stress adaptation. It ...

Plants are constantly sending chemical messages into the air and soil around them. These invisible signals can summon pollinators, warn neighbors of herbivores, or repel attackers. But new research ...

Imagine if a plant in a farmer's field could warn a grower that it needs water? Or if a farmer could signal to plants that dry weather lies ahead, thereby prompting the plants to conserve water? It ...

Plants communicate through volatile organic compounds (VOCs) that help them respond to herbivorous pest attacks. This review explored the mechanisms behind these plant communications and their ...

Traffic lights signal to cars and buses when to stop, slow and go. Much like traffic lights, plant cells send signals to each other to perform photosynthesis to grow or fight off destructive viruses ...

In Lena Mueller’s lab at the Salk Institute for Biological Studies, dead plants are OK. “Don’t worry, it’s on purpose,” said Kelly Semtner, Mueller’s high school intern, gesturing at a row of wilted ...

Plants communicate with other organisms by releasing volatile organic compounds into their environment through their flowers, leaves, and roots. These signaling molecules attract pollinators, repel ...

Plants have evolved elaborate mechanisms for detecting neighboring plants, which typically involve the perception of ‘‘cues’’ inadvertently produced by their neighbors. Strigolactones are hormonal ...

Changes in odor profiles have consequences because odors play a key role in communication between plants, insects, and microorganisms. "Plant diversity has a direct impact on the co-evolution of ...
