Some cut flowers and potted plants are better than others at fending off the aging process, known as senescence. To help tomorrow's blooms stay fresh longer, Agricultural Research Service (ARS) plant physiologist Cai-Zhong Jiang is investigating the gene-controlled mechanisms of plants' aging. Such probing may eventually reveal how to modify flowers' aging-linked genes, or the proteins that are products of those genes. Jiang is with the ARS Crops Pathology and Genetics Research Unit at Davis,...

A team of Agricultural Research Service (ARS) scientists has refined remote sensing tools for identifying invasive Ashe juniper shrubs and trees in central Texas and nearby regions. These findings can help rangeland managers determine the extent and severity of Ashe juniper infestations and boost mitigation efforts. Over the past century, the expansion of Ashe juniper has reduced the production and diversity of other rangeland plant species. Because Ashe juniper has little nutritional value...

Potatoes come in all shapes, sizes and colors-including tubers with red, yellow, orange and purple flesh. This diversity also applies to phytonutrients, Agricultural Research Service (ARS) scientists in Prosser, Wash., are discovering. Together with colleagues, they've devised new analytical procedures for rapidly detecting and measuring phytonutrient concentrations in the tubers. Phytonutrients are plant compounds that are of particular interest for their potential to help diminish the risk...

Algae--already being eyed for biofuel production--could be put to use right away to remove nitrogen and phosphorus in livestock manure runoff, according to an Agricultural Research Service (ARS) scientist. That could give resource managers a new eco-friendly option for reducing the level of agricultural pollutants that contaminate water quality in the Chesapeake Bay. Microbiologist Walter Mulbry works at the ARS Environmental Management and Byproduct Utilization Research Unit in Beltsville,...

Agricultural Research Service (ARS) scientists in North Dakota are evaluating the storage properties of promising new potato varieties that could greatly improve potato quality for growers throughout the United States. Seventy percent of all potatoes in the United States are processed into chips, french fries and dehydrated potato flakes. Maintaining adequate potato storage quality for processing"”in some cases, up to 10 months"”is vital to potato producers and processors. Jeff...

Using herbicides to sterilize rather than to kill weedy grasses might be a more economical and environmentally sound weed control strategy, according to a study by Agricultural Research Service (ARS) scientists and a cooperator. Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., conducted the study with colleagues at Miles City and Robert Masters with Dow AgroSciences LLC, in Indianapolis, Ind. Exotic annual grasses such as...

Agricultural Research Service (ARS) scientists have identified sources of genetic resistance to sheath blight, a major disease affecting rice production worldwide. Sheath blight, caused by the fungus Rhizoctonia solani, is a major disease of rice that affects yield and grain quality. Geneticist Anna McClung, director of the ARS Dale Bumpers National Rice Research Center in Stuttgart, Ark., and research leader of the Rice Research Unit in Beaumont, Texas, heads a group of ARS scientists...

Two Agricultural Research Service (ARS) scientists are part of an international team that has found a way to boost the nutritional value of corn. This has the potential to reduce the number of children in developing countries who lose their eyesight, become ill or die each year because of vitamin A deficiencies. Corn contains carotenoids, some of which the body can convert to vitamin A. Beta-carotene is the best vitamin A precursor, but only a very small percentage of corn varieties have...

Agricultural Research Service (ARS) scientists at the Eastern Oregon Agricultural Research Center in Burns, Ore., are taking a careful look at how grazing cattle affect sage-grouse habitat on high desert rangelands. Cattle share this habitat with sage-grouse, which are chicken-sized birds that are notorious for the showy commotion they create during mating season. But the sage-grouse numbers have declined throughout their range, and the U.S. Fish and Wildlife Service (FWS) has added the...
