Aphid Small Rnas And Viruses, Diveena Vijayendran

Graduate Theses and Dissertations

Aphids are important agricultural pests with about 250 species known to cause damage by feeding on plant phloem and transmitting plant viruses. Current management relies primarily on the application of chemical insecticides, which can be deleterious to the environment, and the use of aphid resistant cultivars hampered by the presence of resistant aphid biotypes. We aim to develop novel biotechnology based approaches to better manage pestiferous aphids. To this end, we (i) identified and characterized aphid viruses, and (ii) analyzed a class of small RNA, microRNAs specific to aphids. We used transcriptome and small RNA sequencing datasets to identify viruses ...
