摘要稻飞虱是水稻上最具破坏性的害虫，其翅型有两种：短翅型和长翅型，短翅型有利于种群的快速增长，长翅型有利于远距离迁飞，这两种翅型共同构成了稻飞虱大发生的机制。在这里，我们表明，Ultrabithorax（UBX）是一个关键的调节器之间切换的长和短翅形式的稻飞虱。Ubx在前翅和后翅的翼垫中都有表达，这与Ubx的典型表达模式不同。在褐飞虱中，Ubx（NlUbx）的表达受水稻宿主的营养状况调节。高质量的幼株诱导NlUbx表达，导致短翅形式;低质量的成熟植株减少NlUbx表达，导致长翅形式。我们还发现NlUbx受胰岛素受体NlInR 1和NlInR 2的调节。NlInR 1的默认表达抑制NlUbx，导致长翅，而高品质宿主诱导NlInR 2表达，其抑制NlInR 1，从而促进NlUbx表达以产生短翅。
Abstract Rice planthoppers, the most devastating rice pests, occur in two wing forms: the short-wing form for rapid population growth and long-wing form for long-distance migration, which together create the mechanism for outbreak. Here we show that Ultrabithorax (Ubx) is a key regulator for switching between the long- and short-wing forms of rice planthoppers. Ubx is expressed in both forewing and hindwing pads, which is different from the canonical model of Ubx expression. In brown planthoppers, expression of Ubx (NlUbx) is regulated by nutritional status of the rice host. High-quality young plants induce NlUbx expression leading to the short-wing form; low-quality ripe plants reduce NlUbx expression resulting in long-wing form. We also showed that NlUbx is regulated by the insulin receptors NlInR1 and NlInR2. The default expression of NlInR1 inhibits NlUbx resulting in long-wings, while high-quality hosts induce NlInR2 expression, which represses NlInR1 thus promoting NlUbx expression to produce short-wings.
