Abstract

A comprehensive understanding of the origin and spread of plastids remains an important yet elusive goal in the field of eukaryotic evolution. Combined with the discovery of new photosynthetic and non-photosynthetic protist lineages, the results of recent taxonomically broad phylogenomic studies suggest that a re-shuffling of higher-level eukaryote systematics is in order. Consequently, new models of plastid evolution involving ancient secondary and tertiary endosymbioses are needed to explain the full spectrum of photosynthetic eukaryotes.

摘要

对质体起源和传播的全面理解仍然是真核生物进化领域一个重要但难以实现的目标。结合新的光合和非光合原生生物谱系的发现，近期分类学范围广泛的系统发育基因组学研究结果表明，高等真核生物系统分类需要重新梳理。因此，需要涉及古代二次和三次内共生的质体进化新模型来解释光合真核生物的全貌。
