Abstract

SUMMARYMyzozoans encompass apicomplexans and dinoflagellates that manifest diverse lifestyles in highly varied environments. They show enormous propensity to employ different metabolic programs and exploit different nutrient resources and niches, and yet, they share much core biology that underlies this evolutionary success and impact. This review discusses apicomplexan parasites of medical significance and the traits and properties they share with non-pathogenic myzozoans. These include the versatility of myzozoan plastids, which scale from fully photosynthetic organelles to the site of very select key metabolic pathways. Pivotal evolutionary innovations, such as the apical complex, have allowed myzozoans to shift from predatory to parasitic and other symbiotic lifestyles multiple times in both apicomplexan and dinoflagellate branches of the myzozoan evolutionary tree. Such traits, along with shared mechanisms for nutrient acquisition, appear to underpin the prosperity of myzozoans in their varied habitats. Understanding the mechanisms of these shared traits has the potential to spawn new strategic interventions against medically and veterinary relevant parasites within this grouping.

不同生活方式和环境下的贻贝原生动物的适应性和新陈代谢进化。
摘要贻贝纲包括类囊体和甲藻,它们在千差万别的环境中表现出多种多样的生活方式。它们在采用不同的新陈代谢程序、利用不同的营养资源和生态位方面表现出巨大的倾向性,然而,它们在许多核心生物学方面却具有共通性,而这些共通性正是它们在进化过程中取得成功并产生影响的基础。这篇综述讨论了具有重要医学意义的类囊体寄生虫,以及它们与非致病性的粘虫共有的特征和特性。这些特性包括:拟水螅质体的多功能性,从完全的光合细胞器到非常精选的关键代谢途径。顶端复合体等关键性的进化创新,使无尾纲动物在无尾纲动物进化树的无尾复合体分支和甲藻分支中多次从捕食生活方式转变为寄生生活方式和其他共生生活方式。这些特征以及共同的营养获取机制,似乎是它们在不同的栖息地中繁衍生息的基础。了解这些共同特征的机理,有可能产生新的战略干预措施,以对付这个类群中与医学和兽医学有关的寄生虫。

期刊介绍: Microbiology and Molecular Biology Reviews (MMBR), a journal that explores the significance and interrelationships of recent discoveries in various microbiology fields, publishes review articles that help both specialists and nonspecialists understand and apply the latest findings in their own research. MMBR covers a wide range of topics in microbiology, including microbial ecology, evolution, parasitology, biotechnology, and immunology. The journal caters to scientists with diverse interests in all areas of microbial science and encompasses viruses, bacteria, archaea, fungi, unicellular eukaryotes, and microbial parasites. MMBR primarily publishes authoritative and critical reviews that push the boundaries of knowledge, appealing to both specialists and generalists. The journal often includes descriptive figures and tables to enhance understanding. Indexed/Abstracted in various databases such as Agricola, BIOSIS Previews, CAB Abstracts, Cambridge Scientific Abstracts, Chemical Abstracts Service, Current Contents- Life Sciences, EMBASE, Food Science and Technology Abstracts, Illustrata, MEDLINE, Science Citation Index Expanded (Web of Science), Summon, and Scopus, among others.
