摘要:

福寿螺是国际自然保护联盟(IUCN)公布的全球100种恶性外来物种之一,严重破坏入侵地农作物生产和水生生态系统稳定,并可作为广州管圆线虫中间宿主传播疾病。福寿螺生态适应性强,在入侵地缺少天敌,一旦定殖形成稳定种群后防制十分困难。研究福寿螺生态适应性机制对科学防制福寿螺具有重要意义。与其他螺群相比,福寿螺功能基因的研究尚未得到足够的关注,关于其生态适应性分子机制的研究相对较少。本文综述了国内外关于福寿螺生态适应性机制相关功能基因的研究进展,包括热休克蛋白、海藻糖合成酶、多功能纤维素酶、蛋白质神经毒素2、细胞色素P450酶系等基因。这些研究结果部分揭示了福寿螺在温度、食物、捕食者、灭螺药物等环境条件影响下自身的适应性变化趋势,但更多内在调节机制尚有待深入研究。

Abstract:

Pomacea canaliculata is one of the 100 worst invasive alien species disclosed by the International Union for Conservation of Nature and Natural Resources (IUCN), which impairs food agriculture and the stability of aquatic ecosystem of the invaded areas, and acts as an intermediate host of Angiostrongylus cantonensis for disease transmission. This species is difficult to prevent and control once a stable colony is formed, due to the high ecological adaptability and the lack of natural enemy. Research on the mechanisms of the ecological adaptability of P. canaliculata is of great significance for the prevention and control. Compared to other species, research on the functional genes of P. canaliculata is still in the preliminary stage, and the molecular mechanisms of the ecological adaptability are far less studied. In this article we review recent findings on the genes closely related to the mechanisms of the ecological adaptability of P. canaliculata, including heat shock proteins, trehalose synthase, multi-functional enzyme gene, perivitellin-2, and cytochrome P450. These results advance our understanding of the adaptability tendency of P. canaliculata under various environmental conditions such as temperature, food, predator, and molluscicides. Further insightful studies are still needed to reveal the regulatoty mechanisms.
