2014 Combined Federal Campaign – “Make it Possible”
CFC is an easy way to participate in your favorite charitable cause, because your donation is deducted from your check each pay period. CFC pledges are made one year at a time; employees must renew their participation each year to continue as a CFC contributor. And if you make a pledge and find that you can't continue, you can change your payroll deduction anytime.
Contact your CFC Coordinator, Rachel LaManna for more information.
Raleigh USDA-ARS Employees Proudly Participate in the CFC
Raleigh area employees participate in the Greater North Carolina Area Combined Federal Campaign (CFC).
The CFC is the Federal employee's best opportunity to give charitable contributions to worthwhile organizations. The opportunities to give are nearly limitless, from helping feed children anywhere in the world, to providing assistance pets for disabled, to preserving open space, to fighting diseases. Any cause that matters to you, it is part of the CFC!
It's amazing how much good can be done, how many less-fortunate people can be helped, with just nominal contributions.
· Just 10 dollars per pay period (a dollar a day) can provide 5 wigs for children undergoing chemotherapy, or buy 5 dozen chicks for egg production in the Caribbean.
· Just 20 dollars per pay period can teach 20 new parents about early childhood development or provide fishing nets and juvenile fish to start a fish farming operation in the Bolivian Andes.
· Just 25 dollars a pay period can give over 260 children nutritious food assistance for a month or supply 125 warm blankets for a refugee family somewhere in the world.
Part of the beauty of the CFC is the payroll deduction feature. You designate an amount per pay period to be deducted.
Paper pledge forms and paper charity listings can be requested from Rachel LaManna. Completed paper pledge forms should be returned to her office (3420 Gardner Hall; Box 7616) during the campaign, usually Sept 1st – Dec 15th every year.
Contact Rachel LaManna (919-513-2037) with any questions you have about CFC.

In 2011, the NCSU Small Grains Extension program, led by Dr. Randy Weisz, started providing very short video “crop alerts” that can be accessed using mobile devices. Building on that effort, Weisz and USDA-ARS Small Grains Pathologist Christina Cowger worked with the North Carolina Small Grain Growers Association and professional videographers to film a series of 4- to 6-minute videos on topics related to small grains production. The videos are targeted to small-grain producers and their advisors. The first set of videos went up on Dr. Weisz’s web site in July 2012: http://www.smallgrains.ncsu.edu/video-library.html
Dr. Weisz reports that visits to his web site increased by five to eight times when he began issuing the video alerts. People watched the alerts on their mobile devices, and then accessed his web site for more information. Cowger is featured in videos on identification and management of four common and damaging diseases in Mid-Atlantic wheat production: powdery mildew, leaf rust, Stagonospora nodorum blotch, and Fusarium head blight (scab).

Researchers at the USDA-ARS Plant Science Research Unit have found a specific gene in corn that appears to be associated with resistance to three important plant leaf diseases.
In a paper published this week in Proceedings of the National Academy of Sciences, ARS plant pathologists and crop scientists pinpoint the gene – glutathione S-transferase – that seems to confer resistance to Southern leaf blight, gray leaf spot and Northern leaf blight, a trio of diseases that cripple corn plants worldwide.
Finding out more about the mechanisms behind complex traits like disease resistance can potentially help plant breeders build the best traits into tomorrow’s corn plants, says paper co-author Dr. Peter Balint-Kurti, a research plant pathologist and geneticist for the U.S. Department of Agriculture-Agriculture Research Service (USDA-ARS) who works in NC State’s plant pathology and crop science departments.
ARS researchers joined lead author Dr. Randy Wisser, an assistant professor at the University of Delaware, and other researchers from the University of Delaware, Cornell University and Kansas State University in examining 300 diverse maize varieties from across the globe which are, on average, as different from one another as humans are from chimpanzees. Using these diverse varieties of corn allowed the researchers to zero in on the regions of the genome responsible for conferring resistance to the three diseases – and thus to varieties that are very resistant to disease.
“We tested the lines for resistance to these three diseases and found that if a line is resistant to one disease, chances are it’s also resistant to the other two,” Balint-Kurti says.
Southern corn leaf blight is a moderate problem in the southeastern United States, Balint-Kurti says, and can be a significant problem in Southeast Asia, southern Europe and parts of Africa. Prevalent in hot, humid climates across the globe, it causes small brown spots on leaves. The spots get larger and eventually spread to the whole plant. Severe infections can cause major corn yield losses. Northern leaf blight can be found in the Midwestern corn belt; it causes cigar-shaped lesions on leaves. Gray leaf spot – which produces an eponymous effect – is found both in the Midwest and Southeast. All three pathogens are so-called necrotrophic fungi, or fungi that kill what they eat.
Balint-Kurti says the study provides “one of the most comprehensive analyses of multiple disease resistance in plants.”
USDA-ARS researchers used an interesting technique to sift through the set of all genes in corn and point out the best candidate areas controlling a specific type of disease resistance. The results may help breeders create a better corn plant.
In a paper published online this week in Nature Genetics, USDA-ARS crop scientists and plant pathologists sifted through millions of genetic sequence variations in the set of all genes in maize (corn) to identify 51 gene regions associated with resistance to Southern corn leaf blight disease – an important plant pathogen.
Finding out more about the mechanisms behind complex traits like disease resistance has the potential to help plant breeders build the best traits into tomorrow’s corn plants, including resistance to some diseases, says Dr. Jim Holland, NC State professor of crop science, research geneticist for USDA-ARS and the corresponding author of the paper.
Holland and study co-authors Dr. Peter Balint-Kurti, a USDA-ARS research plant pathologist and geneticist and Kristen Kump, an NC State graduate student, joined researchers from Cornell University, the University of Delaware and the University of Missouri to examine a set of 5,000 maize varieties called the maize nested association mapping population. Using this population allowed the researchers to zero in on the parts of the genome responsible for conferring resistance.
Holland and Balint-Kurti hope to build upon these results to learn more about how genes confer disease resistance to Southern corn leaf blight and whether they may also provide resistance to other similar types of diseases in corn and other plant species.

Last year, the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) created some optimism among millers up and down the East Coast when it announced the release of “NuEast” (a hard red winter wheat) and “Appalachian White” (a hard white winter wheat).
“Millers and bakers in North Carolina as well as on the Eastern seaboard have always been interested in being able to purchase hard wheat varieties from more local sources,” explains David Marshall, USDA/ARS research leader, who is based at North Carolina State University (NCSU), Raleigh.
The problem has been that developing high-quality hard wheats with the desired disease and pest resistance hasn’t been easy due to the typical high-humidity or rainy conditions of the East Coast. This also causes poor pollination.
“Presently, we aren’t looking at these varieties to go full-scale into the commodity channels,” adds Marshall. “These varieties are intended more for the niche markets, such as organic flours that capitalize on the locally grown appeal.”
Marshall and his team have been working with the North Carolina Organic Bread Flour Project. The project has been examining the qualities of these varieties—grown organically and conventionally. “We’ve approached this breeding program essentially at the grassroots level by trying to get millers and bakers together and seeking their input and involvement as to what they’re looking for in terms of better varieties for the East Coast region,” explains Marshall.
Two New Hard Winter Wheat Varieties: NuEast and Appalacian White
When grown in North Carolina, NuEast produced a good, hard red winter wheat quality grain and flour, according to Marshall. NuEast grain and the quality of flour produced from it performed consistently and equally as well as the Hondo, Jagger, and TAM 303 varieties in field trials conducted in Georgia, North Carolina, Kentucky and Virginia. Hondo is an adapted hard red winter wheat variety for the Mid-Atlantic states.
The test weight of Appalachian White in North Caroina was good and the same as Lakin, another popular hard white winter wheat variety. The same was true in other field trials located in Georgia, Kentucky, Virginia, Maryland and Delaware. Appalachian White produced grain with significantly higher hardness scores and significantly higher flour protein levels than Lakin in trials spanning from 2007 to 2009.
ARS and international cooperators have established the Winter Wheat Stem Rust Resistance Nursery in Ankara, Turkey, to propagate and distribute winter wheat varieties that have been identified as resistant to Ug99.

Nursery is New Tool in Fight against Ug99 Wheat Stem Rust
By Stephanie Yao
The first Winter Wheat Stem Rust Resistance Nursery, a key tool in the fight against the rust strain Ug99, has been established by the Agricultural Research Service(ARS) and international cooperators.
The nursery, established by ARS and the International Maize and Wheat Improvement Center(CIMMYT), is located in Ankara, Turkey, where CIMMYT coordinates its global winter wheat breeding program. It is the first of its kind for winter wheats, and is a joint effort to distribute 100 lines that have been identified by international scientists as having resistance to the deadly Ug99 stem rust and its descendants.
Thirty of the 100 lines in the nursery were developed by ARS scientists and contain resistance to stem rust races in Kenya and the United States. The lines developed by ARS focus on the use of four or five resistance genes that have been incorporated into various combinations in winter wheat lines.
According to David Marshall, research leader of the ARS Plant Science Research Unitin Raleigh, N.C., and coordinator of the wheat screening conducted in Kenya, multiple genes for resistance will slow the pathogen’s ability to readily overcome the new wheat varieties that breeders develop. The amount of time these genes can remain effective is key to maintaining resistance to stem rust in the United States.
Ug99, Puccinia graminis f. sp. tritici, is the most virulent race of stem rust fungus yet to emerge. First discovered in Uganda in 1999, the fungus has spread across Africa, Asia and the Middle East. Ug99 has been able to overcome most of the stem-rust-resistant wheat varieties developed during the past several decades. While other rusts only partially affect crop yields, Ug99 can wipe out entire wheat fields, resulting in 100 percent crop loss.

The Njoro Research Center of the Kenya Agricultural Research Institute (KARI) has been a hotbed of activity these past few years. Since 2005, plant scientists from research organizations around the world, including the Agricultural Research Service, have been sending their countries’ top wheat cultivars and experimental lines to Njoro for testing against Ug99, Puccinia graminis f. sp. tritici,the most virulent race of the stem rust fungus yet to emerge.
“We have molecular markers that allow us to predict the presence of some resistance genes. But the resistance must be confirmed in the field in Kenya or at other locations where the pathogen exists,” says David Marshall, research leader of the ARS Plant Science Research Unit in Raleigh, North Carolina, and coordinator of the screening conducted at KARI.
