CALS Research, NCSU's curator insight, July 18, 2013 1:23 PM

The plant pathogen that caused the Irish potato famine in the 1840s lives on today with a different genetic blueprint and an even larger arsenal of weaponry to harm and kill plants.

In a study published in the journal Nature Communications, North Carolina State University plant pathologist Jean Ristaino and colleagues Mike Martin and Tom Gilbert from the University of Copenhagen compared the genomes, or sets of all genes, of five 19th century strains of the Phytophthora infestans pathogen with modern strains of the pathogen, which still wreaks havoc on potatoes and tomatoes.

The researchers found that the genes in historical plant samples collected in Belgium in 1845 as well as other samples collected from varied European locales in the late 1870s and 1880s were quite different from modern-day P. infestans genes, including some genes in modern plants that make the pathogen more virulent than the historical strains.

Peach genome offers insights into breeding strategies for biofuels crops

Peach genome offers insights into breeding strategies for biofuels crops | Research from the NC Agricultural Research Service | Scoop.it
Rapidly growing trees like poplars and willows are candidate "biofuel crops" from which it is expected that cellulosic ethanol and higher energy content fuels can be efficiently extracted.
CALS Research, NCSU's insight:

Peach Genome Offers Insights Into Breeding Strategies for Biofuels Crops: Dr. Bryon Sosinski of the College of Agriculture & Life Sciences at NC State University is part of the research team which has sequenced Prunus persica, a close relative of potential biofuel crops, poplar and willow. The new sequence data is expected to be helpful in breeding such crops. Read more | http://www.sciencedaily.com/releases/2013/03/130324152303.htm

Research Review: Cattle breed differences in copper use

Research Review: Cattle breed differences in copper use | Research from the NC Agricultural Research Service | Scoop.it
Copper is an important mineral for cattle and one that is often deficient in forages. Copper absorption is negatively affected by other compounds in feed and water such as sulfur and molybdenum.
CALS Research, NCSU's insight:

News from the College of Agriculture and Life Sciences at NC State University"

CALS Research, NCSU's insight:

Listening, Learning, Leading, new #CALS Dean, Dr. Richard Linton, hits the ground running to learn about the College, #NCSU and NC.

 

The Dean has been traversing the state to meet alumni, stakeholders and partners since he arrived a few months ago.

 

“You’ve got to listen & learn before you can lead," he says; "and I think leadership is about providing opportunities, providing opportunities for faculty and staff and students on campus and providing opportunities for us to grow as a state in agriculture and life sciences. And that’s what I think my job should be all about.”

A Single Challenge, a Suite of Experts

A Single Challenge, a Suite of Experts | Research from the NC Agricultural Research Service | Scoop.it
Changing climates mean new stresses for plant life. With NSF support, NC State researchers in computer engineering, biological engineering and plant biology are studying how plants will respond to those stresses.
CALS Research, NCSU's insight:

CALS' plant biologist, Dr. Terri Long (pictured), joins two computer engineers & an environmental engineer in a multidisciplinary team. The group will create computer models of how plants will respond to future stress, such as nutrient deficiencies and climate change, to address world food security.

NC State News and Information » New Algorithm Helps Evaluate, Rank Scientific Literature

NC State News and Information » New Algorithm Helps Evaluate, Rank Scientific Literature | Research from the NC Agricultural Research Service | Scoop.it
CALS Research, NCSU's insight:

"Keeping up with current scientific literature is a daunting task," write Matt Shipman, "considering that hundreds to thousands of papers are published each day. Now researchers from NC State University have developed a computer program to help them evaluate and rank scientific articles in their field.

The researchers use a text-mining algorithm to prioritize research papers to read and include in their Comparative Toxicogenomics Database (CTD), a public database which manually curates and codes data from the scientific literature describing how environmental chemicals interact with genes to affect human health.

 

"Over 33,000 scientific papers have been published on heavy metal toxicity alone, going as far back as 1926,” explains Dr. Allan Peter Davis, a biocuration project manager for CTD at NC State who worked on the project and co-lead author of an article on the work.'“We simply can’t read and code them all. And, with the help of this new algorithm, we don’t have to'.”

 

CALS biologists Thomas Wiegers, Cynthia Grondin Murphy & Carolyn Mattingly worked with Dr. Davis and colleagues at The Mount Desert Island Biological Laboratory on the NIEHS-funded project.

"Dr. Tzung-Fu Hsieh specializes in systems biology, a relatively new research field which studies  interactions between the components of biological systems, and how those relationships affect system functions and behaviors. His area of focus is known as epigenetics, which seeks to understand changes in gene behaviors which are caused by factors other than mutations in DNA.

 

Epigenetics plays an important role in plant development.

 

For example, Hsieh studies the development of endosperms, the placenta-like tissue inside the seeds of most flowering plants, that nourish the embryo. Endosperm plays a critical role in human nutrition and health, accounting for more than 75 percent of the world’s food supply, according to the Food and Agriculture Organization of the United Nations (FAO). That’s because cereal crops like corn, rice and wheat – some of the most widely produced crops in the world – are harvested for their grains, which are mostly endosperm."
