  7. Correlations Between Electron Microscopic and Classical Analytic Observations of Three Strains of Temperature-Sensitive Male Sterility Mutants of <em>Drosophila melanogaster</em>.

    Moody, John Robert, Jr

    Spermatogenesis is a specialized case of cytodifferentiation involving the assembly of cellular components into haploid gametes. It is directed, presumably, by the sequential activation and repression of genes.

  9. Reorganization of Mitochondrial Genomes of Cms-S Maize Associated With Reversion to Fertility and Changes in Nuclear Background (S1 - S2 Plasmids, Cytochrome Oxidase I and Ii, Apocytochrome B)

    Escote, Loida J.University of Illinois at Urbana-Champaign2014

    The cms-S type of cytoplasmic male sterility in maize is characterized by the presence of linear mitochondrial plasmid-like DNAs, S1 and S2. Sequences homologous to S1 and S2 are also found in the main mitochondrial genomes of cms-S and normal fertile lines of corn.

    Perez, Paola2007

    <p>Male sterility systems identified in soybean [Glycine max (L.) Merr.], combined with insect-mediated cross-pollination have been shown to produce large quantities of hybrid seed that can be useful for the identification of heterotic patterns in soybean. This procedure was used in this study to …
