  • North American Invasive Plant Ecology and Management Short Course
    Steve Young syoung4@unl.edu
    Welcome to the North American Invasive Plant Ecology and Management Short Course (NAIPSC) Online Community! The NAIPSC Online Community houses information about the NAIPSC Field Course, instructors, resources, and future opportunities to increase your knowledge of invasive plants. The 2013-2014 NAIPSC Webinar Series The 2013-2014 NAIPSC Webinar Series is now done. NAIPSC members can view the archived version by logging onto the NAIPSC Online Community. For more information about the NAIPSC Webinar Series and the Online Community, contact Steve Young. 2014 NAIPSC Web Course The first annual NAIPSC WC took place January 22-23, 2014. We had great sessions, good discussion, and no one complained about the food, hotel, or flight delays! If you weren't able to join us, don't worry because we recorded each session and have made them available in an 'archived' version. If you want to watch the sessions, contact Steve Young for details. Invasive Plants: Impacts on Ecosystems Are you interested in more than just how to control invasive plants? Have you had questions about where invasive plants occur and how they are impacting the most pristine to the most degraded ecosystems? Maybe you just want to know what an invasive plant is. If so, then you need to sign up for the all new course entitled, "Invasive Plants: Impacts on Ecosystems". In this 15-week course offered through the University of Nebraska-Lincoln, you'll learn how invasive plants in arid climates are affecting hydrological cycles, the changes below-ground caused by invasive plants, the legacies of invasive plants, and much more. The format of this 3-credit course is similar to other college-level courses, except that the all of the instruction, materials, and activities are located online. You can participate from anywhere to hear the pre-recorded lectures, and be involved in the discussion board and complete the problem sets and other various assignments. To put all of your new found knowledge to use, an optional final project on several topics including land manager interviews, invasive plant spotlights, and creating an educational program will be available. For any professional, researcher, student, or instructor working or teaching in the fields of conservation or land management, this course is for you. No other course is going to teach you the 'why' and 'how' relating to the establishment of invasive plants in terrestrial ecosystems. Find out more by contacting Dr. Steve Young (steve.young@unl.edu) or downloading a brochure. The 2014 course has already begun, but a shorter 5-week version is being developed.

    Welcome to the CenUSA Bioenergy Online Peer Network! This space is designed for learning and collaboration. Feel free to browse the reference materials located within the community.  If you would like to view current discussion topics and collaborate with other community members, you'll need to create an account.  Here are instructions to create an account. If you are visiting the community page to attend a webinar, here are instructions on how to use the Adobe Connect meeting room. The CenUSA Bioenergy Online Peer Network is currently funded in part by a USDA/National Institute of Food and Agriculture grant. It is a collaboration among the Plant and Soil Sciences eLibrary, eXtension, university and college educators/students, and researchers. Partners from over 9 states, USDA and 7 universities are members. We launched the fall of 2011.  Please take a look around and we hope you find the materials, webinars, classes and interactions with colleagues in this environment to be rewarding. Together we can meet the fuel needs of a growing population, in the midst of climate challenges. We hope you become a frequent visitor of this site to share with us the experiences of this exciting project.

    Gene Modifications
    This animation shows how a gene is constructed to eventually produce a protein in a Bt corn plant. This is the fifth of a series of seven animations that detail the process of crop genetic engineering. To begin at the beginning, see Overview of Crop Genetic Engineering. (To return to the animation previous to this, go to Gene Regions. To go to the next animation, go to Gene Gun.)

    Herbicide Competition
    This animation shows how herbicides compete with PEP to alter the function of an enzyme.
Featured Lessons
  • Inhibitors of Branched Chain Amino Acid Biosynthesis Herbicides that inhibit the production of the branched chain amino acids valine, leucine and isoleucine are used for total vegetation management and selective weed control in a wide variety of crops.  There are currently four different chemical families that share this MOA.  Before the development of glyphosate-tolerance crop technology, branched chain amino acid inhibitors were the mainstay for several major row crops.  While this is still a very important herbicide MOA, the major increase in herbicide resistance weeds since 1980 has been the direct result selection pressure from these herbicides.  There are currently more weed species resistant to branched chain amino acid inhibitors than any other herbicide MOA.

  • Gene Expression Part 2: Expression of Herbicide Resistant ALS Genes in Plants This lesson describes how changes in the DNA sequence of a gene can alter the synthesis of a protein and thus influence traits such as herbicide resistance.
