Mechanism of yolk formation in the oocytes ofTriturus pyrrhogaster

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The process of yolk formation in the oocytes of the Japanese newt,Triturus pyrrhogaster is described. Ultrastructural evidence reveals that the yolk protein which is synthesised elsewhere is taken into the oocyte through micropinocytosis in the form of yolk precursor bodies. These bodies later grow into yolk plates of definite structure under the influence of mitochondria.
