Isolation, Identification, and Characterization of Novel Viral RNA Dependent RNA Polymerases for Use in Synthetic Biology

In an effort to survey and isolate novel viruses, students sequenced RNA from a collection of arthropods found in the New York area. Students identified and named the novel Jiminy Cricket virus. The virus is composed of a positive-sense single-stranded RNA that encodes four putative open reading frames (ORF1-ORF4) and is related to members of the Negevirus group. RNA transfection of Jiminy Cricket virus into arthropod and mammalian cultures demonstrated limited replication only in arthropod cells, which is consistent with members of this virus group.

Crotalus cerastes is a species of rattlesnake native to the southwestern United States and northern Mexico. Three subspecies have been described, Crotalus cerastes cerastes, Crotalus cerastes cercobombus, and Crotalus cerastes laterorepens. However, subspecies are often classified based on color pattern and other superficial traits that may not represent the evolutionary history of the species. By obtaining DNA from samples of Crotalus cerastes and barcoding them, the students determined the genetic diversity of populations at varying levels of genetic and geographic interconnectedness. The findings suggested that both within the same subspecies and within the same general geographical area, there were significant enough genetic differences that distinct genetic groups could be identified. This implies that the way organisms are grouped into subspecies based on morphology may not be indicative of evolutionary history.

Building a System of DNA Barcodes for Aquatic Species in the Bronx River

This project focused on building a system of DNA barcodes for the fish species in the Bronx River for further environmental research. We collected 11 samples and used two specific primer sets to target two mitochondrial loci, one on the COI gene and one in the 12S locus to amplify the DNA of our samples. 10 out of 11 samples were sent to sequence. However, only 6 samples had high quality DNA sequences that can be used for identification. This project can benefit scientists interested in exploring the fish species or the biodiversity in the Bronx River. Our follow-up project focuses on completing the DNA barcode data for the all fishes in the Bronx River and reporting new DNA sequences to the NCBI database.

Ground Thruthing Environmental DNA Arthropod Profiles Through Single Species Barcoding

The major aims of this study are to 1) characterize aquatic invertebrate biodiversity in NYC, and 2) to compare and contrast DNA barcoding and eDNA metabarcoding approaches for revealing an ecosystem’s taxonomic profile. Additionally, we hope to 3) build a library of local genetic variants for Staten Island.

Using DNA Barcoding Assays to Identify Diatoms in New York City Waterways

Diatoms have been used in forensic investigations to determine if someone died from drowning. Our aim is to find out the most abundant diatoms at one location of New York City waterways. The results of this study can be potentially helpful in drowning investigations by law enforcement agencies.
