摘要

某些昆虫之所以能够取食含有毒性特殊代谢物的植物，可能是由于解毒酶的作用。昆虫食草动物中广泛存在几大家族的解毒酶，这些酶的作用是使毒素功能化，并与极性取代基共轭，以降低毒性、增加水溶性和促进排泄。昆虫还开发出了应对毒素的特殊酶，这些酶在植物受损时被激活。昆虫解毒潜力的另一个来源是它们的微生物组，这些微生物组在处理植物毒素方面的作用正日益得到认可。昆虫解毒系统在抵御植物中有毒的特殊代谢物方面的进化，可能反过来又选择了自然界中种类繁多的此类代谢物。

Disarming the defenses: Insect detoxification of plant defense-related specialized metabolites

The ability of certain insects to feed on plants containing toxic specialized metabolites may be attributed to detoxification enzymes. Representatives of a few large families of detoxification enzymes are widespread in insect herbivores acting to functionalize toxins and conjugate them with polar substituents to decrease toxicity, increase water solubility and enhance excretion. Insects have also developed specific enzymes for coping with toxins that are activated upon plant damage. Another source of detoxification potential in insects lies in their microbiomes, which are being increasingly recognized for their role in processing plant toxins. The evolution of insect detoxification systems to resist toxic specialized metabolites in plants may in turn have selected for the great diversity of such metabolites found in nature.
