Seed Science & Technology

Virtual Webinar Series

You are invited to join us live for our Seed Science and Technology Virtual Webinar Series. Due to Covid-19, the Graduate Program in Seed Technology & Business (STB) at Iowa State University made the decision to cancel its annual November seed science and technology on-campus short course. Since we can’t deliver our week of hands-on workshops and guided industry tours this year, we decided to create some targeted webinars addressing current topics in seed science and technology.

We hope to be back next year to continue our on-campus, hands-on short course, but until then please plan to join us virtually starting at 11:00 am, Monday, November 2nd, and continuing through Friday, November 6th. Please see the complete schedule of virtual webinar sessions below.

You only need to register once to have access to the entire week of sessions. The STB Graduate Program is offering this week of virtual webinars at no charge to you–completely free–so please come prepared with your questions and we hope to see you there!

Phytosanitary Certification for International Seed Movement:
Past and Future

The importance of seed movement across international borders continues to increase as food systems evolve to strengthen global food security. Greg Lamka and Gary Munkvold will discuss phytosanitary regulatory systems and how they are adapting to the increasing volume and frequency of seed shipments. Certifying the phytosanitary safety of seed shipments depends on national regulatory systems and international agreements on phytosanitary standards. Regulatory systems have evolved to manage the growth and complexity of the modern seed supply system, employing accreditation programs that involve collaboration among national plant protection organizations, state agencies, the seed industry, and academia. We will discuss the status of current agreements and regulatory systems and the development of new regulatory frameworks on a global scale.

Gary Munkvold, PhD

Gary P. Munkvold is Professor of Plant Pathology at Iowa State University (ISU), specializing in Seed Pathology. He holds a PhD from the University of California, Davis, and he has worked for more than 20 years in research, extension, and teaching in the Department of Plant Pathology and Microbiology. . .

Seed Health Testing to Meet New Phytosanitary Challenges

The importance of seed movement across international borders continues to increase as food systems evolve to strengthen global food security. Gary Munkvold and Charlie Block will discuss how appearance of new or re-emerging seed-borne pathogens causes challenges for certifying the phytosanitary safety of seed shipments. The safe movement of seeds relies heavily on seed health testing programs. We will discuss seed health testing methods and challenges, and we will delve into several examples of how testing programs have responded to changing pathogen populations and phytosanitary regulations.

CRISPR Genome-Editing as a
Modern B
reeding Technology:
How do we do tt?

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) protein system is a revolutionary tool for precise genome editing. It can be used for targeted mutagenesis, precise sequence modification, transcriptional reprogramming, epigenome editing, and many more. In this webinar, we will review the mechanism and process of crop genome editing. We will compare the CRISPR technology with conventional breeding, marker-assisted breeding and GMO technologies. Finally, we will discuss the recent changes in USDA regulation on bioengineered plants and its implication for future sustainable agriculture and seed improvement.

Keri Carstens, PhD

Plant Biotechnology Regulations:
Past and Future

Keri Carstens and Greg Lamka present an overview of the requirements for a new plant biotechnology event before it becomes deregulated and released into the commercial market. USDA-APHIS is updating these requirements through the SECURE program which will be implemented over the next year.

Revolutions and Changes Underpinning Improved Crop Production:
Are we equipped for the future?

The most fundamental and earliest biotechnological innovation was the domestication and spread of cultivated plant species, a process that began some 8-10,000 years ago independently at several locations globally. Further revolutions had to wait millennia but soon followed upon the rediscovery of Mendel’s Laws in 1900. The discovery of the structure of the DNA molecule in 1953 then set the stage. . .

New Plant Science Technologies – What does it mean to Seed Companies and their Customers?

New technologies provide great opportunities along with some challenges. A seed company’s goal is to provide products that enable customers to be successful. These same seed companies need to create a profit so they can invest in research to develop superior products. We will discuss how seed companies address these challenges in today’s world of ever-increasing sophisticated technology and complexity.

Lab Testing to Reflect Current Needs:
Industrial Hemp and Cover Crops

The cover crop program of NRCS and the wide usage of products from industrial hemp have resulted in seed lab customers less familiar with tests required for sale and use of their seeds. Hemp has been tested since the early 1900’s, but testing beyond purity and germination testing is needed today. Cover crops might only require a warm germination test, but their use or sale may require additional testing. This session examines which tests are needed and briefly looks at how those tests are conducted.

Interaction Between Seeds and Their Environment

In this webinar, Dr. Goggi will discuss the changes in seeds as they develop and mature in the plant, the steps orthodox seeds (most crop and horticultural seeds) undergo to survive dehydration. We will also evaluate the environmental conditions that accelerate or decelerate seed deterioration and death during seeds’ dry state, and learn how different levels of seed deterioration affect seed germination and regrowth under favorable and unfavorable environmental growing conditions. We encourage discussion and questions during this learning session.
