| Popis: | Besides reserve materials (yolk spheres, lipid droplets), ribosomes and various mRNA species, insect oocytes contain large easily morphologically recognizable organelle assemblages: the Balbiani body and the oosome (pole plasm). These assemblages are implicated in the transfer of oocyte components (mitochondria, polar granules) to the embryo that is to offspring. Here, we review present knowledge of morphology, morphogenesis, molecular composition and function/s of these assemblages. We discuss also the morphogenesis and presumed function of unconventional organelle assemblages, dormant stacks of endoplasmic reticulum, recently described in the oocytes and early embryos of a viviparous dermapteran, Hemimerus talpoides. |
