In the News: High School Student Makes Duckweed Discovery

Old Bridge Student Finds Unknown Gene in Duckweed During a Student Scholar Program at Rutgers University

High-throughput Sequencing Services Available from the Waksman Genomics Core Facility

Genomics Facility's High-Throughput, Next Generation Systems offers major advancements in throughput and maximum savings with new technology.

Located on Busch Campus of Rutgers, The State University of New Jersey, the Waksman Institute of Microbiology is an interdisciplinary research institute devoted to excellence in basic research. Focus areas include developmental biology, cell biology, biochemistry, structural biology, genetics, and genomics.

To support the educational mission of Rutgers, Waksman faculty members hold appointments in academic departments throughout the university. Our researchers train undergraduate students, graduate students, and post-doctoral fellows, as well as engage high school students in research through an outreach program.

“Once I entered Rutgers in 2013, I felt like I need to be involved in research because it was calling me,” he said.

Ten Rutgers professors have been named fellows of the American Association for the Advancement of Science (AAAS), an honor conferred on 381 other experts in the U.S. and abroad.

The fellows were chosen by their AAAS peers for efforts to advance science applications that are deemed scientifically or socially distinguished, according to the AAAS.

Andrea Gallavotti, Assistant Professor in the Department of Plant Biology at the Waksman Institute, is a Co-PI of a recently awarded five-year collaborative grant. The project, sponsored by the National Science Foundation and titled “Genomic and Synthetic Approaches Linking Auxin Signaling Modules to Functional Domains in Maize”, seeks to understand how auxin signaling regulates the formation of specific functional domains in maize inflorescences (http://www.nsf.gov/awardsearch/showAward?AWD_ID=1546873).

With generous support from Chancellor of Rutgers New Brunswick, we are pleased to announce the acquisition of a PacBio Sequel DNA sequencer. The Sequel uses Single Molecule Real Time (SMRT) technology to produce long reads, uniform coverage, and high consensus accuracy. The Sequel long 10-15kb reads are ideal for whole genome sequencing, full-length transcript sequencing, or sequencing of long amplicons. Additionally, its SMRT sequencing technology can also be used to directly detect DNA base modifications.

Although some students might relish a respite from the most challenging of school work over the summer months, a couple of Kinnelon High School (KHS) students seized an opportunity to conduct high level scientific research at the Waksman Student Scholars Program (WSSP) Summer Institute at Rutgers University.
 

Madelaine Travaille, the school district's science supervisor, said a science research club was started at KHS in the 2015-16 school year.

The micronutrient boron is essential in maintaining the structure of plant cell walls and is critical for high yields in crop species. Boron can move into plants by diffusion or by active and facilitated transport mechanisms. We recently showed that mutations in the maize boron efflux transporter ROTTEN EAR (RTE) cause severe developmental defects and sterility. RTE is part of a small gene family containing five additional members (RTE2-RTE6) that show tissue specific expression. The close paralogous gene RTE2 encodes a protein with 95% amino acid identity with RTE and is similarly expressed in shoot and root cells surrounding the vasculature. Despite sharing similar functions with RTE, mutations in the RTE2 gene do not cause growth defects in the shoot, even in boron deficient conditions. However, rte2 mutants strongly enhance the rte phenotype in soils with low boron content, producing shorter plants that fail to form all reproductive structures. The joint action of RTE and RTE2 is also required in root development. These defects can be fully complemented by supplying boric acid, suggesting that diffusion or additional transport mechanisms overcome active boron transport deficiencies in the presence of an excess of boron. Overall, these results suggest that RTE2 and RTE function are essential for maize shoot and root growth in boron deficient conditions.

Drug-resistant bacterial pathogens pose an urgent public-health crisis. Here, we report the discovery, from microbial-extract screening, of a nucleoside-analog inhibitor that inhibits bacterial RNA polymerase (RNAP) and exhibits antibacterial activity against drug-resistant bacterial pathogens: pseudouridimycin (PUM). PUM is a natural product comprising a formamidinylated, N-hydroxylated Gly-Gln dipeptide conjugated to 6'-amino-pseudouridine. PUM potently and selectively inhibits bacterial RNAP in vitro, inhibits bacterial growth in culture, and clears infection in a mouse model of Streptococcus pyogenes peritonitis. PUM inhibits RNAP through a binding site on RNAP (the NTP addition site) and mechanism (competition with UTP for occupancy of the NTP addition site) that differ from those of the RNAP inhibitor and current antibacterial drug rifampin (Rif). PUM exhibits additive antibacterial activity when co-administered with Rif, exhibits no cross-resistance with Rif, and exhibits a spontaneous resistance rate an order-of-magnitude lower than that of Rif. PUM is a highly promising lead for antibacterial therapy.
