Viroids : minimal genetic systems : (RNA, plant pathogens, replication, pathogenesis)
(University of Missouri, Agricultural Experiment Station, 1980)
are not encapsidated. Despite their small size, viroids replicate autonomously in cells of susceptible plant species. Known viroids are single stranded, covalently closed circular, as well as linear, RNA molecules with extensive regions of intramolecular...
Evolution and genetic significance of mitochondria
(University of Missouri, Agricultural Experiment Station, 1972)
Mitochondria are constituted of two different membrane systems which may well have quite different origins in replication and evolution. It is hypothesized that the outer membrane is entirely derived from cytosol constituents ...
Divergent and concerted evolution of the two regions encompassing the iso-1- cytochrome c and iso-2-cytochrome c genes of yeast : (saccharomyces cerevisiae, cytochrome c of yeast, evolution of yeast, cloning yeast genes, recombinant DNA, transpositions, composite genes)
(University of Missouri, Agricultural Experiment Station, 1982)
transposition in which a circular intermediate containing the three genes integrated at a new chromosomal position. The order of the genes could have been altered if the circle closed and opened at different sites during the excision and integration...
The genetic complexity of the R locus in maize : (gene complex, regulatory elements, paramutation)
(University of Missouri, Agricultural Experiment Station, 1977)
The evidence on the compound structure of the R locus is reviewed. The more recent analysis of another group of R accessions, collectively known as R-cherry, seems to indicate that this locus is a gene cluster separable ...
Dinoflagellate genetics and DNA characterization : (dinoflagellates, evolution, nucleus, DNA, genetics, mesocaryota)
(University of Missouri, Agricultural Experiment Station, 1976)
Nuclear features of dinoflagellates that were used origin ally to support the Mesocaryota concept are reviewed. Although dinoflagellates possess some procaryotic nuclear features, the remainder of the cell is obviously ...
