BACKGROUND
The evolutionary origin of the eukaryotic nucleus is obscure and controversial. Currently preferred are autogenic concepts; ideas of a symbiotic origin are mostly discarded and forgotten. Here we briefly discuss these issues and propose a new version of the symbiotic and archaeal origin of the eukaryotic nucleus.
SCOPE AND CONCLUSIONS
The nucleus of eukaryotic cells forms via its perinuclear microtubules, the primary eukaryotic unit known also as the Energide-cell body. As for all other endosymbiotic organelles, new Energides are generated only from other Energides. While the Energide cannot be generated de novo, it can use its secretory apparatus to generate de novo the cell periphery apparatus. We suggest that Virchow's tenet Omnis cellula e cellula should be updated as Omnis Energide e Energide to reflect the status of the Energide as the primary unit of the eukaryotic cell, and life. In addition, the plasma membrane provides feedback to the Energide and renders it protection via the plasma membrane-derived endosomal network. New discoveries suggest archaeal origins of both the Energide and its host cell.
背景
真核生物细胞核的进化起源尚不清楚，存在争议。目前，人们更倾向于自体起源的概念，而共生起源的观点大多被摒弃和遗忘。本文简要讨论了这些问题，并提出了一种新的真核生物细胞核的共生和古菌起源的观点。
范围和结论
真核细胞的细胞核通过其核周微管形成，这是已知的初级真核单位，也被称为 Energide-细胞体。与所有其他内共生细胞器一样，新的 Energide 只能由其他 Energide 产生。虽然 Energide 不能从头生成，但它可以利用其分泌装置从头生成细胞外周装置。我们建议将 Virchow 的原则 Omnis cellula e cellula 更新为 Omnis Energide e Energide，以反映 Energide 作为真核细胞和生命的初级单位的地位。此外，质膜通过质膜衍生的内体网络为 Energide 提供反馈并提供保护。新的发现表明 Energide 及其宿主细胞都具有古菌起源。
