    Sorghum is a unique crop in that most varieties are both drought and heat tolerant.

ST. LOUIS, MO, October 2, 2017 – The Donald Danforth Plant Science Center, one of the world’s largest independent plant science institutes, today announced a 5-year $16 million grant from the U.S. Department of Energy (DOE). Building on earlier research using the model grass, green foxtail (Setaria viridis), this project will identify new genes and pathways that contribute to photosynthesis and enhanced water use efficiency. The team will then deploy these genes using tools of the emerging field of synthetic biology to accelerate development of elite energy sorghum varieties for production under marginal environments

“Understanding the network of genes involved in photosynthesis and drought tolerance will provide targets for plant breeders and genetic engineers to re-design sorghum specifically as a high value bioenergy feedstock to be grown on marginal soils and thus not compete with food crops,” said lead principal investigator, Thomas Brutnell, Ph.D., director of the Enterprise Rent-A-Car Institute for Renewable Fuels at the Danforth Center.

This project aims to deliver stress-tolerant sorghum lines, addressing DOE's mission in the generation of renewable energy resources. The development of a low input, environmentally safe and highly productive sorghum germplasm will help establish a lignocellulosic energy economy that can provide jobs to rural communities, ensure energy security and benefit the environment.

The project's strength lies within the multi-disciplinary team’s expertise ranging from plant physiology, genetics, molecular biology, informatics, computational biology and genetic engineering from scientists at Washington State University, Carnegie Institution for Science, University of Rhode Island, University of Illinois, University of Minnesota and the United States Department of Agriculture.

“Sorghum is an attractive bioenergy feedstock supported by well-developed breeding and seed industry,” said co-principal investigator on the grant, Todd Mockler, Ph.D., Geraldine and Robert Virgil Distinguished Investigator at the Danforth Center. “This project will leverage recent investments by DOE to further accelerate sorghum feedstock enhancements, develop new gene editing and transformation technologies and conduct a whole genome association study to identify genes to improve sorghum productivity.”

Sorghum is a member of the grass family and is grown worldwide. Sorghum is very resilient to drought and heat stress. Natural genetic diversity in sorghum makes it a promising system for identifying stress-resistance mechanisms in grasses that may have been lost during the domestication of related cereal crops. It is among the most efficient crops in conversion of solar energy and use of water, making it an ideal crop to target for improvement.

About The Donald Danforth Plant Science Center Founded in 1998, the Donald Danforth Plant Science Center is a not-for-profit research institute with a mission to improve the human condition through plant science. Research, education and outreach aim to have impact at the nexus of food security and the environment, and position the St. Louis region as a world center for plant science. The Center’s work is funded through competitive grants from many sources, including the National Institutes of Health, U.S. Department of Energy, National Science Foundation, and the Bill & Melinda Gates Foundation.

New Computer Model Predicts How Fracturing Metallic Glass Releases Energy at the Atomic Level

Metallic glasses are an exciting research target for tantalizing applications; however, the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a way of simulating to the atomic level how metallic glasses behave as they fracture. This modeling technique could improve computer-aided materials design and help researchers determine the properties of metallic glasses. The duo reports their findings in the Journal of Applied Physics.

The Relationship Between Charge Density Waves and Superconductivity? It's Complicated.

For a long time, physicists have tried to understand the relationship between a periodic pattern of conduction electrons called a charge density wave (CDW), and another quantum order, superconductivity, or zero electrical resistance, in the same material. Do they compete? Co-exist? Co-operate? Do they go their separate ways?

Splitting Water: Nanoscale Imaging Yields Key Insights

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel - just as plants do - researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists at Lawrence Berkeley National Laboratory have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.

New Cost-Effective Instrument Measures Molecular Dynamics on a Picosecond Timescale

Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide "photo-protection" by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.

Exploding Waves from Colliding Dissipative Pulses

The interaction of traveling waves in dissipative systems, physical systems driven by energy dissipation, can yield unexpected and sometimes chaotic results. These waves, known as dissipative pulses are driving experimental studies in a variety of areas that involve matter and energy flows. In the journal Chaos, researchers discuss their work studying collisions between three types of DSs to determine what happens when these traveling waves interact.
