Plants Attract Parasitic Wasps to Defend Themselves against Insect Pests by Releasing Hexenol

BACKGROUND Plant volatiles play an important role in defending plants against insect attacks by attracting their natural enemies. For example, green leaf volatiles (GLVs) and terpenoids emitted from herbivore-damaged plants were found to be important in the host location of parasitic wasps. However, evidence of the functional roles and mechanisms of these semio-chemicals from a system of multip...

Host-pathogen interactions in plants. Plants, when exposed to oligosaccharides of fungal origin, defend themselves by accumulating antibiotics

Plants are exposed to attack by an immense array of microorganisms, yet are resistant to almost all of these potential pests. Many plants respond to an invasion by a pathogenic or nonpathogenic microorganism, whether a fungus, a bacterium or a virus, by accumulating phytoalexins, low molecular weight compounds which inhibit the growth of microorganisms. Phytoalexins are probably also toxic to h...

Gravity Perception: How Plants Stand up for Themselves

Gravity provides a basic polarity for the development, growth and environmental response of plants. Shoots grow up toward a source of light, while roots grow down toward sources of water, nutrients and structural support. Though plant gravitropism has been a topic of research for two centuries [1], the molecular nature of the gravity signaling pathway remains largely unknown. Recent genetic and...
