鼻涕虫和蜗牛特别分泌粘液来帮助它们的运动。这种粘液是软体动物食草动物和植物之间的接触物质。我们最近发现，蛞蝓Deroceras reticulatum的运动粘液含有水杨酸（SA）。1当应用于拟南芥受伤的叶子时，这种粘液诱导SA响应发病机制相关1（PR1）启动子的活性1。在这里，我们分析了PR1启动子的活性与运动粘液的八个鼻涕虫和蜗牛的治疗。虽然没有一种粘液含有SA，但它们的应用仍然引起PR 1启动子活性。这些数据提供了进一步了解软体动物植食动物和植物之间的复杂相互作用。
Slugs and snails specifically secrete mucus to aid their locomotion. This mucus is the contact material between molluscan herbivores and plants. We have recently shown that the locomotion mucus of the slug Deroceras reticulatum contains salicylic acid (SA).1 When applied to wounded leaves of Arabidopsis thaliana this mucus induces the activity of the SA-responsive pathogenesis related 1 (PR1) promotor1. Here we analyzed PR1 promotor activity in response to treatments with locomotion mucus of eight slugs and snails. Although none of the mucus contained SA, their application still elicited PR1 promotor activity. These data provide further insights into the complex interactions between molluscan herbivores and plants.
