Genome Insider Episode 3: River Microbiomes From Around The World

Logo of Genome Insider, podcast of the Joint Genome Institute

The Genome Insider podcast presents JGI-supported research by Kelly Wrighton and her team at Colorado State University in Fort Collins. With more than a dozen principal investigators, the group has a massive undertaking: sequencing the world’s river microbiomes. JGI is a user facility of the Department of Energy (DOE) Office of Science and located at the Lawrence Berkeley National Laboratory in Berkeley, CA.

Natural Prodcast Episode 8: Eric Schmidt

This episode of the Natural Prodcast podcast features guest Eric W. Schmidt from the University of Utah, a natural products chemist who works in a wide variety of marine organisms. The interview was conducted at the SIMB Natural Products conference in January 2020.

JGI Earth Month: The Unusual Metabolism That Helps Plants Withstand Drought

Karolina Heyduk conducting research in growth chamber in both night and daylight conditions. The following info. is provided by Heyduk 1) I cut leaf samples and use them for RNA analysis. This gives us an idea of what genes are expressed in that tissue at the time I harvested them. 2) I take gas measurements because it tells us when the plant is conducting gas exchange – CO2 into the leaf, water vapour out. For C3 plants, this happens during the day. For CAM plants, gas exchange happens at night. Gas exchange patterns are a way for us to assess whether a plant is C3 or CAM. 3) Green light is needed at night because plant stomata (pores on the leaves that allow for gases to enter and exit) respond to blue and red light. Plants are green to us because they reflect green light back while absorbing red and blue! To avoid stomatal opening, we keep to green lights. A key trait of CAM photosynthesis is that plants take up carbon at night and fix it then, as opposed to doing it during the daytime, like C3 plants. Because CAM is active at night, we have to check for gas exchange and gene expression throughout the day/night cycle to capture both C3 and CAM traits.

For JGI Earth Month, Karolina Heyduk, an evolutionary plant biologist at the University of Hawai’i at Mānoa shares how crassulacean acid metabolism, or CAM, helps plants take the heat.

JGI Earth Month: Wetlands Work in #TenHundredWords

JGI Earth Month graphic orange 1000

For JGI Earth Month, graduate student Mo Kaze took on the challenge of explaining her research using the ten hundred most commonly used words in the English language. Her work focuses anthropogenic impacts on wetland microbiome composition and metabolism. The #TenHundredWords Challenge was inspired by Randall Munroe’s xkcd comic “Up Goer Five” and his subsequent book Thing Explainer.

Enediynes, enabling technologies, and leveraging a large microbial strain collection for natural product discovery. In Episode 7 of Natural Prodcast, Ben Shen from The Scripps Research Institute (TSRI) chats with Dan Udwary and Alison Takemura about enediynes and their use in medicine, how Ben got fascinated with natural products by working on terpene chemistry, TSRI’s acquisition of the Pfizer strain collection, and our collaborations to sequence that collection, mine genomes, and develop new technology to access natural products.
