SPEAKER: Mr. Bryce Lane, Lecturer & Undergraduate Coordinator, Dept of Horticultural Science, NCSU
TITLE: Gardens of Lake Maggiore & Northern Italy
Join Bryce as he takes a tour of the Northern Lake District of Italy.  Having traveled and studied in this area several times over many years, Bryce’s knowledge of the history and horticulture in the region will be the highlight of this special seminar.

DATE: Monday, November 28, 2011
SPEAKER: Ms. Julieta Sherk, Landscape Horticulturist, Dept of Horticultural Science, NCSU
TITLE:  Enhancing Learning and Empathy: Social Action in the Community Design Study Abroad Program in Cordoba, Mexico

DATE: Monday, November 21, 2011
SPEAKER: Rhonda Conlon, Director, Extension Information Technology, CALS, NCSU
TITLE:  Dealing with the Data Deluge
Not that long ago, we complained about receiving too much email. Now, even more information is coming at us... in many forms, from everywhere and everyone. In his 2011 book, Curation Nation, author Steven Rosenbaum quotes Google CEO Eric Schmidt's description of today's information management challenges: "Between the dawn of civilization through 2003, there was just five exabytes of information created. That much information is now created every two days, and the pace is increasing." How can we find the information we need? How can we be heard? What applications will help us? How do I know I won't just be wasting my time? During this seminar, we will explore a variety of strategies and tools that can help you better manage and even leverage this tremendous increase in the volume of online information.

SPEAKER: Dr. Sophia Kathariou, Department of Food, Bioprocessing and Nutrition Sciences, NCSU
TITLE:  Unprecedented Incidents of Disease via Contaminated Produce: What are We Learning From Them?
During 2011 two  major outbreaks of human disease exhibited an  unprecedented array of attributes: the outbreak of Shiga toxin-producing Escherichia coli O104:H4 in northern Germany  (and subsequently in France) resulted in >4,000 cases and unparalleled disease burden. Many of the victims were previously healthy young  adults; there was a surprisingly high frequency of hemolytic uremic syndrome, and 50 deaths.  The agent exhibited a unique  array of attributes, constituting a novel pathovar of E. coli.   In the United States, a major, multistate outbreak of listeriosis this summer and fall  involved whole   cantaloupe, a vehicle never before associated with outbreaks involving Listeria.  Contamination was traced to the facility  where the cantaloupes were cooled and washed prior to shipping.  At least 133 cases and 28 deaths were attributed to this outbreak.  This presentation will discuss the unique attributes of these outbreaks and will also present laboratory findings related to the ability of Listeria to adapt to the ecosystem of processing facilities.  Industry responses aimed at reducing contamination risks and associated disease burden will also be discussed.

DATE: Monday, October 31, 2011
SPEAKERS: Sarah Noell, Assistant DirectorOutreach, Communications, and Consulting
and Janyne Kizer, Systems Programmer Administrator, Extension Information Technology, CALS, NCSU
TITLE:  Google Apps @ NC State - what's it all about?
Join Sarah Noell and Twanda Baker from OIT and Janyne Kizer from CALS to hear about NC State's migration to Google Apps and the opportunities it provides for you and your department. The Google Apps suite provides email, calendar, documents and sites for your use. OIT will discuss the final migration of GW users to Google occurring on November 30 as well as spending time talking about how you can use calendaring and docs to collaborate, share, and communicate with your colleagues.

TITLE: Inheritance of anthracnose crown rot resistance in the commercial strawberry (Fragaria x ananassa)
Strawberries, genus Fragaria L., are the most economically important soft fruit in the world. Of 21 species of Fragaria, the dessert strawberry (Fragaria x ananassa) is the most widely grown and can be found worldwide over a range of latitudes for both fresh consumption and processing. A sizable strawberry industry has developed in the southeastern United States through adopting cultivars that were developed for commercial production in California. While these cultivars have the potential to perform well in the Southeast, they often suffer from diseases that are not typically problematic in western strawberry production. One of the major constraints on strawberry production in the Southeast is a disease known as anthracnose crown rot caused by the fungal pathogen Colletotrichum gloeosporioides. This pathogen has two major phases to its disease cycle. In the first phase, C. gloeosporioides infects foliar tissue but remains in a symptomless quiescent state. This phase can last for several months during which the pathogen increases its levels of inoculum in individual leaves and throughout a production field. In a second phase of infection, the pathogen breaks its quiescent state and infects the crown of the plant, quickly causing wilting and total plant collapse. C. gloeosporioides' unusual disease cycle renders conventional disease management strategies costly and largely ineffective. Breeding for resistance to anthracnose crown rot represents the most effective strategy for managing this disease. This study is being conducted to: 1) Determine sources of resistance to anthracnose crown rot, 2) Investigate the infection biology of C. gloeosporioides in order to better understand host-pathogen interactions, 3) Determine if there is a rate-limiting form of foliar resistance that could limit the reproductive fecundity of the pathogen, 4) Develop and utilize creative tools for screening germplasm for resistance to anthracnose crown rot, and 5) Implement breeding methods that will most effectively determine the genetic parameters behind the inheritance of resistance to anthracnose crown rot. A better understanding of how this resistance is inherited will allow it to be more effectively utilized in a breeding program to develop commercially valuable cultivars.

SPEAKER: Mr. Greg Kraus, Outreach, Communications and Consulting, University IT Accessibility Coordinator
TITLE: Tips and Tools for Making Sure Online Content is Accessible
NC State recently approved a new Information and Communication Technology Accessibility Regulation. This seminar will show you techniques for ensuring all of your electronic content meets these requirements. This includes course content, electronic newsletters, PDF documents, and any piece of information your department produces on the Web. Making some key decisions early in the content creation process will make the entire process much easier in the long run. Learn how common tools such as Microsoft Word and other products available on campus can be used to make accessible content.

SPEAKER: Mr. Benard Yada
TITLE:  Development of SSR markers and QTL analysis of disease and pest resistance in sweetpotato
Sweetpotato (Ipomoea batatas, [L.] Lam), the fifth most important global crop after rice, wheat, maize and cassava is predominantly grown in the developing world for food, feed and source of income. Production is constrained severely by sweetpotato virus disease and weevils leading to 67-100% yield losses. Breeding for disease and pest resistance is the most effective control strategy. This study is being conducted to: 1) Develop high density SSR genetic linkage maps for populations segregating for SPW and SPVD resistance; 2) Phenotype the two sets of mapping population for weevil and SPVD resistance, dry matter and beta-carotene content; 3) Profile octadecyl and hexadecyl esters of hydroxycinnamic acids from the root latex of the SPW resistance population; 4) Detect QTLs associated with field weevil and SPVD resistance, octadecyl and hexadecyl ester production, dry matter and beta-carotene content. QTLs identified will be used for sweetpotato breeding through marker assisted selection.
