TY - JOUR AU - Kosina, Romuald AU - Krawczyk, Joanna PY - 2016 TI - Antipodal symmetry and asymmetry in the embryo sac of Avena sativa L. JF - Modern Phytomorphology; Vol 10 No Suppl. (2016) DO - 10.5281/zenodo.159037 KW - N2 - Inter- and intra-antipodal variation is presented for a free-nucleolar developmental stadium in the Avena sativa endosperm. Antipodals of common oat are uni- or multinuclear. Multinuclear antipodals, in a single cell, show nuclei of the same mitotic stage, but this is different for various antipodals. Examples of DNA amplification and anomalies occurring during mitosis are provided. UR - http://ojs.phytomorphology.org/index.php/MP/article/view/3
