Our knowledge on the variability of the reduced forms of endosymbiotic organelles - mitochondria and plastids - is expanding rapidly, thanks to growing interest in peculiar microbial eukaryotes, along with the availability of the methods used in modern genomics and transcriptomics. The aim of this work is to highlight the most recent advances in understanding these organelles' diversity, physiology and evolution. We also outline the known mechanisms behind the convergence of traits between organelles which have undergone reduction independently, the importance of the earliest evolutionary events in determining the vestigial organelles' eventual fate, and a proposed classification of nonphotosynthetic plastids.
我们对内共生细胞器（线粒体和质体）的简化形式的变异性的了解正在迅速扩展，这要归功于人们对奇特的微生物真核生物的日益关注，以及现代基因组学和转录组学方法的应用。本工作的目的是强调在理解这些细胞器的多样性、生理学和进化方面的最新进展。我们还概述了独立经历简化的细胞器之间特征趋同的已知机制、早期进化事件对决定退化细胞器最终命运的重要性，以及非光合质体的拟议分类。
