Genomic Workshop for Native American College students

A Genomic Science Workshop was held  last week (May 24-26, 2016) at the J Craig Venter Institute Rockville campus for a group of ten Native American college students.  The students participated in two full-day intensive training activities learning how to study the “microbiome” of natural water sources. Each student had the chance to perform hands-on lab work including DNA isolation from an environmental water source, PCR of the 16S ribosomal RNA gene, and gel electrophoresis. Individual computer workstations were provided for the computer lab sessions for students to follow along.  The group was introduced to basic Linux command-line analysis and the popular 16S analysis package QIIME. Overall, the workshop provided the students a foundation of knowledge and tools to identify and classify microbial populations in environmental water sources, and enabled the students to participate in water quality analysis and monitoring efforts of their homeland reservations.

The workshop students were welcomed by JCVI President Karen Nelson and Rockville Campus Director Rembert Pieper. Informal discussion panels were also held to provide networking and research career development opportunities with invited guest speakers including Science Education Directors from the Howard Hughes Medical Institute (HHMI), and Native research scholars from the National Institute of Health (NIH). The students were also presented with a preview of the astronaut microbiomes as an application of human microbiome study. Workshop students also had the opportunity to visit the US Capitol and the National Museum of the American Indian.

The workshop was funded by the National Science Foundation through a Maize Cell Genomics grant and was organized by Agnes Chan (JCVI; co-PI), in collaboration with the Cold Spring Harbor Laboratory (CSHL; PI Dave Jackson, Outreach Educator Joslynn Lee), the University of Wyoming (UW; co-PI Ann Sylvester), Montana State University (Mari Eggers), and the Little Big Horn College (LBHC; John Doyle).  LBHC is a tribal college located in the Crow Reservation, MT. The NSF Maize project has established a long-term outreach relationship with LBHC, and has organized a number of training workshops for Native students previously at LBHC, UW, and CSHL. Participants for the 2016 workshop included Native students recruited from the LBHC, Montana State University, Fort Lewis College, and Northern Arizona State University.

The PIs of the Maize Genomics Project would like to express sincere thanks to instructors from JCVI including Hernan Lorenzi, Yongwook Choi, Vivek Krishnakumar, Stephanie Mounaud,  the JCVI Information Technology team, the Administrative Assistant team, and all colleagues for their generous assistance, support, and patience for a successful outreach educational workshop.

Understanding Complex Data through Better Visualization

Recently, researchers at JCVI reported on the Rhizoctonia solani mitochondrial genome which was the largest fungal mitochondrion to be sequenced to date. We showed that its unusually large size was probably due to the expansion of multiple genetic elements that populated the genome in somewhat of a ‘parasitic’ relationship. The visualization was meant to impress the number and variety of these repetitive genetic elements, and was selected in a commentary in  FEMS Microbiology Letters as an example of how to summarize molecular data in order to obtain an overall view of the results.

The outermost circle represents the chromosome and repetitive elements. Other important features such as genes, endonucleases, exons, RNAseq coverage are represented in the concentric circles respectively. Grey links represent short repeats (< 35bp) found up to 100 times in the genome; colored links show the location of repeats and follow the coloration in Track 1.

We are also excited to announce the new Genomics Scholar Program beginning this summer and also accepting applications.  The Genomic Scholar Program (GSP) is a targeted research experience program to community college students in Rockville. Our program incorporates multiple avenues of support for students through the research experience with the Principal Investigators as mentors, and supplemental professional development provided by the JCVI.  Additionally, selected students will have the opportunity to participate in undergraduate research conferences.

The GSP is supported by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health under award number R25DK098111.

Plant Bioinformatics Workshop

JCVI recently held its 3rd Annual Plant Bioinformatics Workshop from July 15-19th. During the week-long workshop, 20 scientists from the Plant Research community visited JCVI and learned many aspects of Bioinformatics from the members of Chris Town’s Plant Genome group. Attendees included undergraduate and graduate students, post-doctoral fellows, research scientists and faculty at various Universities throughout the United States as well as a biotech company. In addition to the on-site participants, we had 5 additional participants attend the workshop via WebEx. The virtual participants had the opportunity to sit in on the lectures and complete the hands on exercises by logging into an Amazon Cloud instance, which was set up specifically for this purpose. The topics covered during the workshop included UNIX tools for Bioinformatics, Genome Assembly, Structural and Functional Annotation, RNA-seq assembly and analysis and SNPs. In addition to JCVI’s instructors, we had additional sections covered by external instructors. Eric Lyons (University of Arizona and iPlant) presented on Comparative Genomics and the iPlant Infrastructure and Ann Loraine (UNC Charlotte) presented on Integrated Genome Browser. All sessions contained a hands-on component so the students would have the opportunity to use the tools that we discussed during the lecture portion.  Watch our website for future offerings!


A Look Back at 2010 at the JCVI…

As the J. Craig Venter Institute (JCVI) soars into its 19th year, we reflect on the past year of highlights and accomplishments to mark the close 2010 and look forward to more significant scientific advances in 2011.

JCVI Top 10 of 2010 …

1. First Synthetic Cell: Fifteen years in the making, 2010 brought to bear with huge anticipation the successful construction of the first self-replicating, synthetic bacterial cell. The work was published in Science in May. The synthetic cell called Mycoplasma mycoides JCVI-syn1.0 is the proof of principle that genomes can be designed in the computer, chemically made in the laboratory and transplanted into a recipient cell to produce a new self-replicating cell controlled only by an artificial genome. Although the first synthetic cell was not designed to produce a specific bioproduct, the team has shown that this can be done and the potential benefits are numerous. The research team, lead by JCVI President Craig Venter, Hamilton Smith, Clyde Hutchison, and Daniel Gibson, envision a future where the rapid design and production of biological products using synthetic biology techniques will be used to produce clean fuels, medicines, and other bioproducts. Throughout the course of this work, the JCVI Policy group has extensively engaged in outside review of the ethical and societal implications of this work, including advising the new Presidential Commission on Bioethics on their recommendations for oversight.

2. Synthetic Vaccines: Following on the heels of the announcement of the first synthetic cell, the company Synthetic Genomics Inc. and JCVI announced in October the formation of a new company, Synthetic Genomics Vaccines Inc. (SGVI). The privately held company is focused on developing next generation vaccines that can be rapidly produced and tested, which is especially important for outbreaks of new infectious diseases. SGVI also announced a three-year collaboration with Novartis to apply synthetic genomics technologies to accelerate the production of the influenza (flu) seed strains required for vaccine manufacturing. The seed strain is the starter culture of a virus, and is the base from which larger quantities of the vaccine virus can be grown. Under this collaboration, Novartis and SGVI will work to develop a “bank” of synthetically constructed seed viruses ready to go into production as soon as WHO makes recommendations on the flu strains. The technology could reduce vaccine production time by up to two months, which is particularly critical in the event of a pandemic.

3. Hydra Genome – one of the animal kingdom’s earliest common ancestors: JCVI scientists along with more than 70 other researchers from around the world, have sequenced and analyzed the genome of Hydra magnipapillata, a fresh water member of the cnidaria– stinging animals that include jellyfish, sea anemones and corals. The research, published in the March 14 edition of Nature, was co-led by Ewen F. Kirkness, JCVI, Jarrod A. Chapman, Department of Energy Joint Genome Institute, and Oleg Simakov, University of California, Berkeley. This is the second sequenced cnidarian genome, following that of a sea anemone, Nematostella vectensis, in 2007. The ancestors of these two species diverged more than 500 million years ago, and comparison of their genomes has revealed common features of the earliest animals that gave rise to the diversity of animals on Earth today. The team found clear evidence for conserved genome structure between the Hydra and other animals, like humans. Unexpectedly, the sequencing also revealed a novel bacterium that lives in close association with the Hydra.

4. Uncovering the Human Microbiome: Microbes are living within and on the human body and this collective community is called the human microbiome. JCVI Scientists, as one component of the large scale NIH Roadmap Human Microbiome Project, and along with colleagues at three other genome centers sequenced the genomes of ~180 microbes from the human body, published in the May 21 edition of Science. At the JCVI we anticipate sequencing an additional 400 species over the next few months. Colleagues at the JCVI are also using single cell approaches to isolate new strains that have not been cultured – isolates whose genomes will also be completely sequenced. The role these microbes play in human health and disease is still relatively unknown and these approaches are allowing us to gain a greater understanding of these enigmatic species.

5. Body Louse Genome: A global research team led by Ewen Kirkness and colleagues from JCVI published a study in the Proceedings of the National Academy of Sciences in June describing the sequencing and analysis of the human body louse, Pediculus humanus humanus, a human parasite responsible for the transmission of bacteria that cause epidemic typhus, relapsing fever and trench fever. Detailed analysis of the genome was then conducted by a large international group of 71 scientists, coordinated by Barry Pittendrigh, University of Illinois, and Professor Evgeny Zdobnov, University of Geneva Medical School. Comparative studies of the body louse genome with other species revealed features that will enhance our understanding of the relationships between disease-vector insects, the pathogens they transmit, and the human hosts. In addition to the targeted louse genome, the project unexpectedly yielded the complete genome sequence of a bacterial species, Riesia, that lives in close association with lice, and which is essential for survival of the insects. The researchers believe that the genome will be a valuable reference for evolutionary studies of insect species, especially in the areas related to insect growth and development.

6. Castor Bean Genome Sequencing: A research team co-led by Agnes P. Chan and colleagues from JCVI and Jonathan Crabtree and others at the Institute for Genome Sciences, University of Maryland School of Medicine, published the sequence and analysis of the castor bean (Ricinus communis) genome in Nature Biotechnology in August. Because of the potential use of castor bean as a biofuel and its production of the potent toxin ricin, the team focused efforts on analysis of genes related to oil and ricin production. The analyses could be important for comparative studies with other oilseed crops, and could also allow for genetic engineering of castor bean to produce oil without ricin. Identifying and understanding the ricin–producing gene family in castor bean will be important in preventing and dealing with potential bioterrorism events. Genomics enables enhanced diagnostic and forensic methods for the detection of ricin and precise identification of strains and geographical origins. As a next step, the group suggests further comparative genomic studies with the close relative cassava, a major crop in the developing world, to further elucidate their disease resistance aspects.

7. Science Education: JCVI was an Official Partner of the inaugural USA Science and Engineering Festival held on the National Mall in Washington, DC in October. The Festival, which was the country’s first national science festival, included over 500 of the country’s leading science and engineering organizations with the aim to reignite the interest of our nation’s youth in the sciences. The JCVI ‘Discover Genomes’ Bus was showcased during a two-day expo and some of the research being done at JCVI was presented to around 1700 visitors by our scientists and staff.

There were lines all day!

8. Viral Genomics– In 2010 the JCVI has published over 1600 influenza genomes and over 75% of all published flu genomes to date have been sequenced by the JCVI, totaling over 6000 genomes. This year the diversity of viral genomes we have sequenced has significantly expanded under the NIH Genomic Sequencing Center for Infectious Diseases contract. Some of the projects include viruses causing diseases such as measles, mumps, rubella, encephalitis, SARS, and the common cold, just to name a few. The viral group has annotated and published 79 Rotavirus (stomach flu) and 33 Coronavirus genomes (includes SARS and common cold) this year and many more will be published in 2011. The pace of sequencing and finishing genomes has also increased this year as a result of adoption of nextgen platforms (e.g. Illumina/454 and Illumina/Solexa) and the development of more efficient methodologies to increase productivity while reducing costs.

9. Marine Microbial Genome Sequencing Project: JCVI scientists have continued their quest to isolate and sequencing microbes living in global ocean waters to discover new genes and enzymes, and to help understand the role microbes play in the ocean ecosystem. Shibu Yooseph, Kenneth Nealson and colleagues at JCVI published an analysis of 137 known marine microbial genomes living in the global ocean surface in Nature in November. These genomes were compared to metagenomic samples of ocean waters of 10.97 million sequences of JCVI’s Sorcerer II Global Ocean Sampling (GOS) metagenomic data and thousands of 16S rRNA sequences. The marine genomes were collected as part of the Gordon and Betty Moore Foundation-funded Marine Microbial Genome Sequencing Project, a project coordinated by JCVI that has a primary goal of obtaining whole genome sequences of ecologically important microbes from a variety of diverse, global marine environments. The work provides a good example of combining metagenomic data with sequenced genomes data to study microbial communities and to generate testable hypotheses in microbial ecology.

10. Sorcerer II Global Ocean Sampling Expedition: On December 17th 2010 Sorcerer II arrived in Florida after spending the last two years with her crew collecting samples in The Baltic, Mediterranean and Black Seas. Funded generously by the Beyster Family Foundation Fund, The San Diego Foundation, and Life Technologies Foundation, Sorcerer II has sailed ~28,000 nautical miles since departing San Diego in March 2009. During this time 212 samples were collected and over 5,100 liters of sea water was filtered and sent to JCVI for analysis of the microbial life contained within these samples. The JCVI established strong collaborations with scientists in all 16 countries in which samples were collected, which will lead to joint publications and future collaborative studies in the new year.
