Location: Tick and Biting Fly Research
Project Number: 6205-32000-036-00
Start Date: Jun 01, 2014
End Date: May 31, 2019
Utilize advanced bioinformatic assembly and annotation protocols to attain a draft annotated R. microplus genome sequence of sufficient quality for publication in international peer-reviewed journals. The assembled and annotated sequence will be made available for the scientific community at CattleTickBase (http://ccg.murdoch.edu.au/cattletickbase) and GenBank. Sequence the horn fly genomic DNA with similar protocols and caveats utilized to sequence the tick genome. The horn fly genomic DNA to be sequenced will be obtained from a laboratory colony maintained since 1961 at our laboratory, reared in cages and feeding upon cotton pads saturated with citrated bovine blood. The assembled sequence will be available for the scientific community by submission of the data to GenBank. Identify candidate vaccine antigens through reverse vaccinology from datasets obtained from prior project or as part of objective 1 of this project. Utilize real-time PCR to study metabolic-based pesticide resistance and quantify gene expression of specific horn fly cytochrome P450s in populations of horn flies with known metabolic resistance-based mechanisms. Use a transcriptomic approach to sequence nuclear and mitochondrial genes from tick collections in Indian and Philippine collections to use for phylogenetic comparisons to the Texas outbreak R. microplus Deutsch population that was used in prior R. microplus transcriptome studies.
