Abstract
VARIOUS fibrillar systems have been demonstrated in recent years in chloroplasts but all were limited to stroma regions or to pyrenoids of plastids. Ris and Plant1 found 25 Å microfibrils in areas of Chlamydomonas chloroplasts which resemble nucleoplasms of bacteria and blue-green algae and which correspond to DNA macromolecules with respect to their location, morphology, and sensitivity to DNase digestion. Gunning2,3 confirmed these results in an investigation of Avena plastids fixed with glutaraldehyde osmium tetroxide and revealed also areas of aggregated fibrils, each 85 Å in diameter, which he named “stromacenters”. The dense matrix material of pyrenoids in green algae consists mainly of tightly packed fibrils approximately 60 Å in diameter according to Gibbs4.
