To investigate the mode of inheritance of apomixis in Chinese chive, the degrees of diplospory and parthenogenesis were evaluated in F(1) and BC(1) progenies derived from crosses between amphimictic and apomictic diploids (2n = 16, 2x). The F(1) population was generated by crossing three amphimictic

Fungal species of the Neotyphodium and Epichloë genera are endophytes of pasture grasses showing complex differences of life-cycle and genetic architecture. Simple sequence repeat (SSR) markers have been developed from endophyte-derived expressed sequence tag (EST) collections. Although SSR array s

Malignant melanomas are characterized by increased karyotypic complexity, extended aneuploidy and heteroploidy. We report a melanoma metastasis to the peritoneal cavity with an exceptionally stable, abnormal pseudodiploid karyotype as verified by G-Banding, subtelomeric, centromeric and quantitative

… Based on the cytological observation, the embryos in the (3n×2n)eggs were heteroploid (about 70 chromosomes)., the histological observation of the embryogenesis of (3n×2n) eggs, revealed of the presence of severe abnormalities and the, eggs eventuelly died during subsequent embryonic development.On the basis of these results, we suggested that death by abnormal embryogensis in the (3n×2n) eggs may be ascribed to heteroploidy. …
