摘要 在几种眼虫(E. mutabilis、E. gracilis T、E.spec.)中,短圆柱形袋是从管附近的储层腹侧表面向内折叠而形成的。该结构与一条微管带相连,该微管带与眼虫鞭毛根系统的腹侧鞭毛根相同。 E. 鞭毛根系统的绝对构型分析。 mutabilis 以及与无色眼虫藻和博多类(动质体)鞭毛器的比较揭示了眼虫的储存袋和这些生物体的细胞口之间的结构和位置同源性,并有力地支持了眼虫藻从动质体的系统发育以及从吞噬无色类群进化出绿色眼虫藻。讨论了眼虫隐性胞口与细胞内共生细菌的发生有关的功能意义。
SummaryA short cylindrical pocket arises as an infolding from the ventral surface of the reservoir near the canal in several species ofEuglena (E. mutabilis, E. gracilis strain T,E. spec.). The structure is linked to a band of microtubules which is shown to be identical to the ventral flagellar root of the euglenoid flagellar root system. An absolute configuration analysis of the flagellar root system inE. mutabilis and a comparison with the flagellar apparatus of colourlessEuglenophyceae and the bodonids (Kinetoplastida) reveals structural and positional homology between the reservoir pocket ofEuglena and the cytostome of these organisms and strongly supports the phylogenetic derivation of theEuglenophyceae from theKinetoplastida and the evolution of greenEuglenophyceae from phagotrophic colourless taxa. The functional significance of the cryptic cytostome ofEuglena is discussed in relation to the occurrence of intracellular endosymbiotic bacteria.
