摘要

查尔斯·达尔文认识到,食肉植物通过捕捉动物在营养贫乏的土壤中茁壮成长。虽然植物食肉性的概念已经被发现了近150年,但其分子机制和进化起源直到最近才被很好地理解。在过去的十年里,技术进步推动了主动和被动猎人的基因组和转录组测序,从而更好地理解了与食肉综合征相关的特征,从捕蝇草(Dionaea muscipula)、猪笼草(Cephalotus follicularis)和狸藻(Utricularia gibba)的叶子发育和猎物消化到营养吸收。防御相关基因的再利用是植物食肉动物进化的一个重要趋势。本文以捕蝇草为代表,综述了捕蝇草吸引、诱捕和消化猎物的分子机制,并从基因组进化的角度讨论了植物食肉性的起源。

On the Origin of Carnivory: Molecular Physiology and Evolution of Plants on an Animal Diet.

Charles Darwin recognized that carnivorous plants thrive in nutrient-poor soil by capturing animals. Although the concept of botanical carnivory has been known for nearly 150 years, its molecular mechanisms and evolutionary origins have not been well understood until recently. In the last decade, technical advances have fueled the genome and transcriptome sequencings of active and passive hunters, leading to a better understanding of the traits associated with the carnivorous syndrome, from trap leaf development and prey digestion to nutrient absorption, exemplified, for example, by the Venus flytrap (Dionaea muscipula), pitcher plant (Cephalotus follicularis), and bladderwort (Utricularia gibba). The repurposing of defense-related genes is an important trend in the evolution of plant carnivory. In this review, using the Venus flytrap as a representative of the carnivorous plants, we summarize the molecular mechanisms underlying their ability to attract, trap, and digest prey and discuss the origins of plant carnivory in relation to their genomic evolution.
