UCR Biochemist Goes to Washington with High-Protein Corn

22.09.2005


Daniel Gallie’s findings propose a useful approach to feed the world’s growing population



Corn with twice its usual content of protein and oil and about half its usual carbohydrate content is what Daniel Gallie, professor of biochemistry, will present at a congressional seminar in Washington, D.C., this week.

Because his research holds promise for efficiently feeding high-protein corn to people and livestock all over the world, Gallie has been invited to speak to an audience of congressional staff in the Longworth House Office Building of the U.S. House of Representatives. His 45-minute presentation is scheduled for 10 a.m., Sept. 23.


The National Coalition for Food and Agricultural Research, a broad-based coalition of agricultural producers, science societies and universities, is sponsoring the seminar.

In the United States, the vast majority of corn – nearly 65 percent – is used to feed animals for meat production. Much of the remainder is exported to other countries for feeding animals or made into corn sweeteners or fuel alcohol. Corn, the most widely produced feed grain in the United States, accounts for more than 90 percent of total value and production of feed grains in the country, with around 80 million acres of land planted with corn.

Gallie’s research on doubling the protein content of corn grain adds significant value to the crop, benefiting corn producers. Moreover, his technology nearly doubles corn oil, the most valuable content of corn grain, and significantly increases the grain’s value. Corn is processed also into other food and industrial products such as starch, sweeteners, beverage and industrial alcohol, and fuel ethanol.

“Nearly 800 million people in the world suffer from protein-energy malnutrition, which is a leading cause of death in children in developing countries, many of which already produce corn as a major cereal crop,” said Gallie. “A significant fraction of the world’s population, particularly in developing countries, has no access to meat as a protein source, and has to rely on plant sources such as grain. The new corn we have developed has two embryos in its kernel, which is what doubles the content of protein and oil and reduces the starch content. It could provide a good source of protein for those that depend on grain as their primary source of nutrients.”

Every corn kernel results from a flower on an ear of corn, Gallie explained. Initially the ear produces a pair of flowers for every kernel. But then one of the sister flowers undergoes abortion, resulting in one flower for each kernel. Gallie’s research group has developed technology that essentially rescues the aborted flower, resulting in two kernels that are fused together. “Despite the fusion, the kernels are not bigger,” Gallie said. “It’s basically the same corn, except that it is protein-rich and starch-poor – something that, if applied to sweet corn, would appeal to a large number of weight-conscious people in this country who are interested in low-carb diets and who normally avoid corn in their diets.”

Gallie and his colleagues published their work last year in The Plant Journal. Though their research focused on feed corn, the technology can easily be applied to sweet corn, a sugar-rich mutant strain of regular corn.

The U.S. Department of Agriculture, the National Science Foundation, and the California Agricultural Experiment Station funded the research.

Details of the study:

Flowers in the corn ear develop in pairs but one from each pair aborts before pollination can occur. Because of the role cytokinin, a plant hormone, plays in preventing organ death, Gallie’s research group introduced a gene that enabled production of cytokinin, thus rescuing the flowers. The kernels produced from pairs of flowers fused into a single normal-sized kernel that contained two embryos and a smaller endosperm, the food storage tissue that provides nutrients to the developing embryo. Because the embryo contains the majority of protein and oil, two embryos in the kernel doubles the protein and oil content in corn grain. The nutritional value of the grain improves also because the size of the endosperm, which contains most of the carbohydrates, is reduced.

Brief biography of Daniel Gallie:

Daniel Gallie received his doctoral degree in 1985 from the University of California, Davis. After completing postdoctoral studies at the John Innes Institute in Norwich, England, and at Stanford University, he joined UCR in 1990. During his career, Gallie has investigated the regulation of protein synthesis, the function of heat stress proteins, the control of cell death in plants, the role of plant hormones such as ethylene and cytokinin during plant growth and development, and the function of vitamin C in a plant’s response to adverse environmental conditions. Results from his group have been published in over 100 papers and patents. He is a member of the American Society of Plant Biologists, a professional society devoted to the advancement of the plant sciences.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
