UC's Tango mandarin touted in Smithsonian

UC Riverside research that resulted in the new, seedless mandarin variety Tango was featured in a Smithsonian magazine article written by Sarah C. Rich.

The story recounts how plant geneticist Mikeal Roose used irradiation on W. Murcott budwood to induce mutations that improve the fruit.

“Farmers have long selected citrus varieties that are low-seed, that have the same kinds of chromosomal rearrangements stimulated by the same thing—there’s natural radiation around all the time and it can affect the trees at any time.”

The advantage of inducing mutations, Roose explained, rather than waiting for the sun to trigger genetic variation, is that it can be targeted toward manipulating one particular feature—a kind of rapid prototyping for agriculture. The radiation accelerates the output of new genetic compositions. Each is then cultivated, screened and tested with the hope that at least one offspring will be reliably superior to its antecedent.

'Doom the Broom' demo is scheduled Thursday in Paradise
Chico Enterprise-Record

A live fire demonstration will help illustrate the need to clear growth from around structures and to be aware of the growth of Scotch, Spanish and French broom Thursday in the parking lot at 5400 Clark Road, Paradise, Calif. Glenn Nader, UC Cooperative Extension advisor for Sutter-Yuba counties, an expert in livestock and natural resources, will talk about spraying herbicides to control the weeds.

The event will go from 10:30-11:45 a.m., rain or shine. The fire demonstration will be at 11:05 a.m.

Grass-fed beef fights cancer, study finds

Several studies suggest that eating grass-fed beef elevates precursors for Vitamin A and E, as well as cancer-fighting antioxidants such as glutathione and superoxide dismutase, compared with eating beef from grain-fed animals, says a research review published in the current issue of Nutrition Journal.

The review, written by three Chico State professors and UC Cooperative Extension livestock advisors Glenn Nader and Stephanie Larson, reported that grass-fed beef has an overall lower fat content.

"However, consumers should be aware that the differences in (fatty acid) content will also give grass-fed beef a distinct grass flavor and unique cooking qualities," the researchers wrote.

In addition, the fat from grass-finished beef may have a yellowish appearance from the elevated carotenoid content (precursor to Vitamin A).

The research prompted San Francisco Examiner blogger Joshua Horrocks to ponder whether grass-fed beef is the key to cancer prevention. He noted that, in addition to grass-fed beef's higher levels of antioxidants, it has lower concentrations of monounsaturated fatty acids. MUFAs have been linked to a higher mortality rate for women.

The researchers have developed a Grass-Fed Beef Web page with information on the product's health benefits, niche marketing, labeling, cost of production and more.
