Genome Insider

What if we understood plants and how they adapt to their ever-changing environments better? We could unlock new innovations to drive more productive food, medicine, and bioenergy crops. But most available genomes are from narrow swaths of the plant tree of life. One project aims to change that.

You might know sorghum as an edible grain. But there are some sorghum varieties, grown on marginal land with little water, which were developed specifically to turn their biomass into sustainable biofuel and bioproducts. John Mullet, a biologist at Texas A&M University, tells us how sorghum’s historical — and literal — roots could play a big role in our energy future.

Lawrence Livermore National Lab biologist Jennifer Pett-Ridge collaborated with JGI scientists on an ambitious project: to bring in robots to help process experiments that measure microbial activity in soil. Now, the researchers and robots have made these experiments easier for scientists everywhere.

Biofuels and bioproducts are a way to kick our addiction to fossil fuels. In this episode, we get a peek into how scientists Aindrila Mukhopadhyay and Steve Singer are harnessing the versatile bacterium Pseudomonas putida to break down biomass and help bring about a more sustainable, bio-based economy. They conduct research at the Joint BioEnergy Institute (JBEI), a JGI partner and one of the four US Department of Energy Bioenergy Research Centers.

Diatoms, a group of tiny algae, are also known as “living opals” because of the strange, beautiful properties of their silica shells. But what genes are responsible for such mesmerizing exteriors? Setsuko Wakao and Kris Niyogi, biologists at UC Berkeley and Lawrence Berkeley National Laboratory, aim to find out.

A tall native plant of the North American prairie, switchgrass (Panicum virgatum) has long been a tantalizing potential biofuel feedstock. But switchgrass has a complex genome and, as a species, encompasses dizzying diversity. So, a team of scientists made an ambitious plan to link the plant’s diverse traits — height, biomass, hardiness to cold, etc. — to its genes. The undertaking took shovels, trucks — and more than a decade.
