Viroids : minimal genetic systems : (RNA, plant pathogens, replication, pathogenesis)
(University of Missouri, Agricultural Experiment Station, 1980)
SViroids are nucleic acid species of relatively low molecular weight and unique structure that cause several important diseases of cultivated plants. Viroids are the smallest known agents of infectious disease. Unlike viral ...
Pattern formation in the drosophila embryo : (Developmental genetics, combinatorial code, compartments)
(University of Missouri, Agricultural Experiment Station, 1981)
Three plausible hypotheses about developmental commitments in the Drosophila embryo propose: 1) A micromosaic of localized determinants in the egg trigger somatic commitments. 2) Monotonic anterior-posterior and dorsal-ventral ...
