CHLOROPLAST DIVISION AND PYRENOID FORMATION IN CHLAMYDOMONAS REINHARDI 1

Ursula Goodenough

Open publisher page 82 citations

Abstract

SUMMARY The process of chloroplast division during mitosis in Chlamydomonas reinhardi is followed with the electron microscope. The pyrenoid and the chloroplast reproduce by fission. The dividing chloroplast contains regions of dense material that superficially resemble pyrenoids, but it is concluded that the formation of the dense material is not related to pyrenoid formation in C. reinhardi. The dense material appears to be localized over regions of chloroplast DNA.
