蚜虫表现出丰富的适应性，这些适应性在现有模型系统中不容易研究。在这里，我们回顾了一种新的基因组模型系统——豌豆蚜（Acyrthosiphon pisum）的生物学。然后，我们讨论了在豌豆蚜中特别容易研究的几个现象：多型现象的发育遗传基础、蚜虫-细菌共生体、适应遗传学和病毒传播机制。豌豆蚜可以在实验室中饲养，也可以在田间研究自然种群。这些特性允许对与自然蚜虫种群直接相关的问题进行受控实验。结合新的基因组方法，豌豆蚜有望成为理解许多生态和进化相关问题的分子和发育基础的重要模型系统。
Aphids display an abundance of adaptations that are not easily studied in existing model systems. Here we review the biology of a new genomic model system, the pea aphid, Acyrthosiphon pisum. We then discuss several phenomena that are particularly accessible to study in the pea aphid: the developmental genetic basis of polyphenisms, aphid-bacterial symbioses, the genetics of adaptation and mechanisms of virus transmission. The pea aphid can be maintained in the laboratory and natural populations can be studied in the field. These properties allow controlled experiments to be performed on problems of direct relevance to natural aphid populations. Combined with new genomic approaches, the pea aphid is poised to become an important model system for understanding the molecular and developmental basis of many ecologically and evolutionarily relevant problems.
