Abstract

At times, symbiote populations in mycetomes of Helochara communis are apparently increased by translocation of symbiotes from adjacent mycetocytes. These symbiotes appear to reproduce in mycetomes and become phagocytosed by 'auxiliary' cells (probably hemocytes) that invade mycetomes at zones of disruption supposedly resulting from reproduction of the translocated symbiotes. Some phagocytosed symbiotes degenerate in large vacuoles; others become lodged in smaller vacuoles that supply a third membrane. The hemocytes fuse and form additional mycetomal syncytia.

摘要

有时,普通沼梭(Helochara communis)菌胞体内的共生体种群数量显然会因相邻菌细胞内共生体的转移而增加。这些共生体似乎在菌胞体内繁殖,并被“辅助”细胞(可能是血细胞)吞噬,这些“辅助”细胞在据推测是由转移的共生体繁殖所导致的破坏区域侵入菌胞体。一些被吞噬的共生体在大液泡中退化;另一些则滞留在提供第三层膜的较小液泡中。血细胞融合并形成额外的菌胞体多核体。
