Connection between the mitochondria and endoplasmic reticulum in oocytes of loach (Misgurnus fossilis L.)
A considerable number of mitochondria (10-20 percent) are closely connected with the granular endoplasmic reticulum at the early stages of oogenesis in loach. The number of ribosomes on sections of the endoplasmic reticulum turned toward the mitochondria is considerably greater than on other sectors of the membranes. The work discusses the role played by contacts between the mitochondria and the granular endoplasmic reticulum in the biogenesis of oocyte mitochondria at the early stages of oogenesis.
