Genome Insider Episode 4: The Big Deal About Short Plants

Logo of Genome Insider, podcast of the Joint Genome InstituteThe Genome Insider podcast presents JGI-supported research on the “short plant,” Ceratodon purpureus or fire moss. Its genome could shed light on gene function in other plants, including bioenergy sources. Guests Stuart McDaniel and his then-graduate student Sarah Carey of the University of Florida were interviewed at the Plant & Animal Genome (PAG) Conference held in early 2020. [Read More]

Genome Insider Episode 3: River Microbiomes From Around The World

Logo of Genome Insider, podcast of the Joint Genome InstituteThe 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. [Read More]

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 1000For 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. [Read More]
