植物在遭受到机械损伤或昆虫取食后释放出的伤诱导挥发物,除了具有防御功能外,还可作为伤害信息在植株间传递,引起群体诱导抗性的产生.文中就伤诱导挥发物在植株间传递伤害信息的存在证据、伤害信息分子的可能标准以及植物对伤害信息的感知进行了综述.
Either mechanical damage or insect feeding makes plants emit some volatiles which not only have indirect and direct defense functions but also act as wounding signal transmiting among plants. The present paper reviews evidence for the transfer of wounding signals among plants, criteria for the successful signals and their perception by plants.
