Valladares, F/ Ascaso, C 1994: Quantitative approach to the fine structure of both symbionts of nine Umbilicaria species. - Protoplasma178: 168-178. [RLL List # 156 / Rec.# 19231] Keywords: HAUSTORIA/ MYCOBIONT/ ORGANELLES/ PHOTOBIONT/ PHYCOBIONTS/ PYRENOIDS/ TEM/ ULTRASTRUCTURE/ UMBILICARIA/ VOLUME DENSITY
Abstract: 7 fig. [TEM study. "The stereological parameter Vv (volume density) has been estimated for the most important organelles and cellular structures in order to quantify their volumetric contribution to the cells of both symbionts and to assess their inter- and intraspecific variability."]
