Double-Stranded Rna Binding Protein, Staufen, Is Required For The Initiation Of Rnai In Coleopteran Insects, June-Sun Yoon, Kanakachari Mogilicherla, Dhandapani Gurusamy, Xien Chen, Shankar C. R. R. Chereddy, Subba R. Palli

Entomology Faculty Publications

RNA interference (RNAi) is being used to develop methods to control pests and disease vectors. RNAi is robust and systemic in coleopteran insects but is quite variable in other insects. The determinants of efficient RNAi in coleopterans, as well as its potential mechanisms of resistance, are not known. RNAi screen identified a double-stranded RNA binding protein (StaufenC) as a major player in RNAi. StaufenC homologs have been identified in only coleopteran insects. Experiments in two coleopteran insects, Leptinotarsa decemlineata and Tribolium castaneum, showed the requirement of StaufenC for RNAi, especially for processing of double-stranded RNA (dsRNA) to small interfering …

Appraisal For Combined Pea Aphid And Spotted Alfalfa Aphid Resistance In Alfalfa, W. L. Howe, W. R. Kehr, C. O. Calkins

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Sources of combined resistance to spotted alfalfa and pea aphids were found in Ranger alfalfa and its parental strains, foreign plant introductions, clones and their progenies. Ranger alfalfa appeared to be a good source for selection of plants with resistance to both aphids.
