Perinuclear P granules are asymmetric. (A) One arm of the adult hermaphrodite gonad showing nuclei (black) and P granules (green). (B) A single P granule as described in the text; compare with F. env, nuclear envelope; Pg-NPCs, P granule-associated nuclear pore complexes. (C-E) Examples of small, possibly newly formed, P granules in the mitotic zone showing nuclear pores (small black arrows), presumptive crests (white arrows) and the base (black arrowhead). (F-H) Perinuclear P granules in the pachytene zone (F,G) and in a late oogonium (H); note that NPCs are not clustered in late oogonia and oocytes. (I) Detached, cytoplasmic P granule in a young oocyte. Arrows and arrowheads are the same as in C-E. Scale bars: 500 nm.
