Non Technical Summary
Seeds are the foundation of agricultural systems that feed humanity. In fact, seeds of wheat, maize and rice account for 70% of global food calories. Likewise, seeds are increasingly important in habitat restoration, production of aesthetic and non-food products, and to fulfill fiber and fuel needs. Seeds also represent the main laboratory-to-field delivery system for technologies addressing significant agricultural problems such as enhanced crop performance under stressful conditions, disease and insect control, and weed management. Therefore, seeds play numerous, indispensable roles in agricultural systems confronted with current and future challenges related to food security, energy needs, natural resources protection and sustainable agricultural intensification in the face of climate change. Communicating new advances in seed biology research ensures robust agricultural systems primed to confront these problems. However, expansion of new seed-based solutions that enhance U.S. agriculture are at risk due to decreases in research programs and educational opportunities within seed science. Thus, objectives of the 12th International Seed Conference are to: 1) enable exchange of new scientific information that can stimulate innovation needed to generate novel solutions and 2) improve educational experiences and career prospects of future seed scientists. The objectives will be achieved by inviting leading global seed scientists to discuss how seeds function as or within biological systems. Moreover, post-doctoral and graduate researchers will actively particpate in the program by co-hosting oral session, delivering invited presentations and introducing posters via 1-minute talks. Additionally, a workshop will focus on career opportunities and networking for this group of newly trained scientists.

Goals / Objectives
The overall goal of the conference is to share knowledge of seed biology from the point of view of their functions as plant developmental systems and components within agricultural, microbial and ecological systems. Participants will use this information to improve the production and utilization of seeds as commodities, propagules, delivery systems for advanced technologies and repositories of plant germplasm. Additional goals of the conference will be to assess the global status of seed biology education and to attract more students into careers in seed biology and the seed industry.
Project Methods
The program envisions one invited/primary speaker in each major topic, with additional speakers selected from submitted abstracts. There will also be sessions devoted to short oral presentations and to poster presentations. The following is a programmatic agenda:Keynote speakers - The International Seed Science Society (ISSS) has three major awards, the Alfred Mayer Plenary Lecture, the Mike Black Founders Lecture and the Derek Bewley Lecture. The recipients of these awards have not been announced yet, but they will all be prominent seed scientists, including an outstanding young scientist for the Mike Black Lecture.Seed Developmental Systems - This section includes topics in seed development but with focus on how cellular/developmental mechanisms integrate into systems to achieve the desired end, whether seed quality or crop yield. This includes systems biology with respect to transcriptomics and metabolomics, but also emphasizing how these systems could be utilized to increase seed yield or quality. This could include maternal/filial tissue interactions, whole plant source/sink relationships in seed development, and relationships of seed developmental regulation to other stages of the life cycle.Seed Germination and Dormancy Systems - Research on germination and dormancy is evolving toward understanding how the key hormones (e.g., GA, ABA, ethylene) interact with other regulatory systems to convey environmental information thereby influencing the decision to germinate. This includes systems interacting at the molecular, cellular or tissue levels to control the initiation of embryo expansion and more ecological or population level systems determining how environmental factors influence dormancy and germination in relation to environmental signals.Seed Microbial Systems - There is strong interest in identifying microbes that have specific effects on plant growth or resistance to pathogens or pests. Many companies are pursuing biologically based approaches to protect plants or stimulate their growth. Seeds are expected to be a critical delivery system for establishing beneficial microbes in the field, as has long been the case for Rhizobium. But experience to date suggests that this will not be simple to achieve and more information is needed on how the seed microflora interacts with the soil microflora. This program section would focus on seed/microbe interactions, including both beneficial and pathogenic microbes.Seed Ecological Systems - Seed ecology clearly lends itself to the systems theme and the impacts of climate change on seeds in natural and agricultural systems are of importance. The focus would be on ecosystem-level changes as impacted by climate and the physiological systems that determine seed responses, issues for vegetation restoration, and invasive weed control.Seed Conservation Systems - The majority of crop germplasm is conserved as seeds, made possible by the developmental, physiological and biophysical systems that enable desiccation tolerance and longevity of dry seeds. These traits and their impacts should be considered in collection or reproduction of materials for storage or conservation. Biophysical systems are also prominent in seed storage conditions, in contrast to the metabolic systems normally focused on in seed biology. Reactive oxygen species represent a unique system that can span the biophysical and metabolic realms. Understanding how these different systems interact is critical to extending storage techniques to recalcitrant seeds, meristems or tissue cultures that currently are difficult to preserve.Seed Scanning Systems - There are a number of nondestructive scanning technologies that are being adapted to visualize, measure, categorize and sort seeds. These technologies can identify diseased seeds, internal deficiencies and compositional differences among seeds. Raman spectroscopy, infrared spectroscopy, hyperspectral imaging and chlorophyll florescence are some of the promising technologies available that can be applied to seed technology to improve quality. These technologies can also assist seed analysts to detect foreign matter and weed seeds in seed samples and in quality assessment of commercial commodities (e.g., rice grain). This session will be co-sponsored by the International Seed Testing Association.Student and Postdoc Program - Each major plenary session will include a presentation by a student or post-doctoral researcher. They will also be invited to be session chairs for oral sessions and will participate in poster sessions. Prior to the two planned poster sessions, graduate students and post-doctoral researchers presenting in the following session will introduce their posters in 1-minute talks. In addition, a workshop will focus on career opportunities and advancements for newly trained scientists in the agriculture sector and will have panel members from private companies, government, and universities working in seed science. The panel will be designed to specifically address the questions and future career options of post-doctoral researchers and students.Tours and Site Visits - One morning of the meeting will be devoted to tours to the Salinas, Gilroy and San Juan Bautista areas of California to visit facilities of seed and seed technology companies. Numerous companies are located in this region and are willing to host visits by participants. The fresh vegetable season is still in progress at this time (September 10-14), so participants will also see large-scale vegetable crop (e.g., lettuce, broccoli, cauliflower, celery and strawberry) production, harvesting and processing systems that are unique in the world.Seed Trade Exhibits - Following the different tours, we plan for participants to gather at a single location in Salinas for lunch and a trade show to provide seed, seed technology, robotics, greenhouse, and other companies and suppliers an opportunity to demonstrate their products. There are many such companies in the area and sponsorship contributions for participation in the trade show will help defray costs for the conference.

Impacts
What was accomplished under these goals? Impact of the Project - New advances in seed biology research are vital components of a robust agricultural production system poised to meet current demands and future challenges related to food security, energy conservation, protection of natural resources, and sustainable agricultural intensification in the face of climate change. Moreover, seeds are a major food source for humans (70% of global food calories are from wheat, maize and rice grains) and domesticated animals. Improved varieties developed to enhance crop performance and yield are largely transferred to agricultural practice as seeds. In addition, seeds are key delivery system for technologies that address significant agricultural problems. In particular, control of diseases and insects can be delivered by seeds through enhanced genetic resistances and via seed treatments. Likewise, weed control through management of weed seed production and seed dormancy in soil seed banks is receiving greater attention due to reduced herbicide effectiveness linked to weed resistance mechanisms. Thus, seeds play multiple, essential roles in agricultural systems and advancing the progress of seed science through improved communication takes on ever-greater importance. The 12th International Conference on Seeds, sponsored in part by the International Society for Seed Science (ISSS) and USDA-NIFA Regional Research Project W-3168, provides a unique opportunity for such global communication. In addition to attracting the leading seed scientists to share their latest advances, a critical need exists to enhance the recruitment, retention and pipelining of future seed scientists. An international team (11 U.S., 7 Europe, 1 South Africa, 1 South America; 6 female, 14 male; 18 seed scientists, 2 support personnel) organized and operated the conference. The conference drew 180 attendees from 24 different countries. Scientists presented 66 oral presentations and 55 posters. Graduate students delivered roughly 45% and 33% of oral presentations and posters, respectively. Post-doctoral researchers provided almost 8% and 2% of oral presentations, respectively. Additionally, students participated in speed networking activities, attended a seed science career panel, served as session co-chairs, and provided 1-minute introductions for their posters. The 12th International Conference on Seeds: 1) enabled exchange of new seed science information; 2) improved the educational and professional development of future seed scientists; and 3) facilitated movement of the same group into the seed science workforce. This, in turn, leads to: advances in agriculture delivered through seeds as improved varieties or as technologies applied to seeds; improved seed quality for farmers; and highly skilled seed scientists to contribute to addressing the challenges of national and global agricultural production. Objective #1: Enable exchange of new scientific information that can stimulate innovation needed to generate novel solutions - The 12th International Conference on Seeds attracted 180 attendees from 24 different countries. The conference included the following seven sessions: Seed Development Systems, Seed Microbial Systems, Seed Ecological Systems, Seed Germination Systems, Seed Conservation Systems, Seed Dormancy Systems and Seed Scanning Systems. Scientists presented 66 oral presentations and 55 posters. Graduate students delivered roughly 45% and 33% of oral presentations and posters, respectively. Post-doctoral researchers provided almost 8% and 2% of oral presentations, respectively. We hosted three invited plenary speakers (1 Europe, 1 USA, 1 South Africa; 1 female, 2 male) and 14 invited keynote speakers ( 1 Austalia, 1 Canada, 7 Europe, 5 USA; 5 female, 9 male). We observed increased knowledge of current and future seed scientists and industry stakeholders. This was evident in the lines of questioning posed by audience members and discussions among attendees. Scientists also presented new basic and applied seed biology knowledge. Objective #2: Improve educational experiences and career prospects of future seed scientists - We created a student/post-doctoral researcher program to enhance professional development. This program consisted of Speed Networking, Sceed Science Career Panel, Co-Chairing Scientific Sessions and presenting 1-minute poster introductions. Thirteen seed companies participated in the Speed Networking activity. Student groups rotated between companies every 4 minutes. We attracted 65 undergraduate students from local universities, 20 graduate students, and three post-doctoral researchers to the Speed Networking activity. The number of male students (n=48) slightly edged that of female students (n=40). Interestingly, 68% of student participants identfiied with a traditionally under-represented minority. Seventeen students particpated in the Seed Science Career Panel. The five panelist ( 2 female, 3 male), from various sectors of seed science (1 botanical garden/seed conservation, 2 industry, 2 research institute/university; 4 Europe, 1 USA), provided advice and perspectives in response to audience questions. Likewise, eight students (4 female, 4 male; 3 Europe, 5 USA) volunteered to serve as scientific session co-chairs. FInally, seven students (28%) paticipated in 1-minute talks. These activities contributed to an improvement in knowledge if potential employment opportunities while expanding professional development of graduate students and post-doctoral researchers.
