Plants tag insect herbivores with an alarm

...ogens such as bacteria and fungi can all set off a variety of peptide warning signals in plants, which respond by increasing phytohormones, particularly ethylene, jasmonic acid, or salicylic acid, that regulate defensive responses. But which peptide signals act as alarmsand how" To address those questions,...

The opossum genome sequence casts light on evolution, immunity and disease
