Although study of the toxicity of metallic nanoparticles in aquatic organisms is increasing, there is still little known about their combined toxicity, especially in a comparative and integrated approach. The objective of this study is to compare the toxicity of copper nanoparticles (CuNP), chromium nanoparticles (CrNP), and their mixtures to crucian carp (Carassius auratus) through a comprehensive...
Cytoplasmic male sterility (CMS) is an important trait in rice (Oryza sativa L.) breeding because it provides a source for producing hybrid seeds. In rice CMS lines, ATPases involved in the oxidative phosphorylation complexes are believed to be dysfunctional due to the expression of rice CMS-related gene orf79. In the present study, a new type of CMS line named CMS-ZA (ZidaoA) was used. We found an...
By colchicine treatment of hybrids between Triticum turgidum and Aegilops tauschii (as seedlings), a fertile wheat plant (SHW-L2) carrying 56 chromosomes was artificially synthesized. At metaphase I of 50 pollen mother cells, the 56 chromosomes of the new wheat SHW-L2 showed a mean pairing configuration of 2.82 univalents, 6.18 rod bivalents, 19.39 ring bivalents, 0.5 trivalents, and 0.14 quadrivalents...
