NIFA supports the latest plant breeding, genetics, and genomics research to ensure that U.S. agriculture is prepared to meet the grand challenges facing the world. Innovation in agricultural production is key to producing more food with less impact on the environment.

Agriculture of the future will be enabled by genome design, innovative breeding methods, data analysis, and knowledge of molecular and biological processes. Breeding crops for the future will require new traits, breeding platforms built for quick transfer of traits to elite cultivars, coordination of breeding efforts in public and private domains, and training for current and future plant breeders and researchers

The curriculum in genetics is based on preparation in biology, chemistry and biochemistry, as well as genetics. In this program, you will receive an understanding of modern methods of genetic engineering and will be prepared for jobs in industry and for further work in the biological sciences, including graduate, veterinary or medical school.

Students prepare for many research opportunities in industry and acquire the necessary background for graduate studies. Students also learn the fundamentals of genetics and practical plant breeding as well as the latest developments in genetic engineering, environmentally sound crop production practices, development of varieties appropriate for the agriculture of developing countries, and strategies for developing plant lines adapted to environmental stresses. Opportunities exist for training both in laboratory and field practices important to modern genetics research. A professional internship involving practical aspects of the option is required.

The Germplasm Resources Information Network (GRIN) provides information about USDA national collections of animal, microbial, and plant genetic resources (germplasm) important for food and agricultural production. GRIN documents these collections through informational pages, searchable databases, and links to USDA-ARS projects that curate the collections.

GRIN products include several applications developed by the National Germplasm Resources Laboratory in Beltsville, MD. GRIN-Global includes the ARS version of a public website for the U.S. National Plant Germplasm System, which curates more than 600,000 active accessions of plant genetic resources for food and agriculture.

The National Plant Germplasm System (NGPS) is a collaborative effort to safeguard the genetic diversity of agriculturally important plants. The mission of the NPGS is to support agricultural production by acquiring, conserving, evaluating, documenting, and distributing crop germplasm.

The goal of this program is to ensure that the genetic diversity of agriculturally important microorganisms is maintained to enhance and increase agricultural efficiency and profitability.The program will collect, authenticate and characterize potentially useful microbial germplasm; preserve microbial genetic diversity; and facilitate distribution and utilization of microbial germplasm for research and industry.

GRIN provides access to data maintained within its database, supporting both searches and export. The Rhizobium collection of nitrogen fixing bacteria is maintained by the ARS Soybean Genomics and Improvement Laboratory in Beltsville, MD. Plant Variety Protection Certificates are issued by the Plant Variety Protection Office of the USDA Agricultural Marketing Service.

Most of the foods we eat today were created through traditional breeding methods. But changing plants and animals through traditional breeding can take a long time, and it is difficult to make very specific changes. After scientists developed genetic engineering in the 1970s, they were able to make similar changes in a more specific way and in a shorter amount of time.

1986: The federal government establishes the Coordinated Framework for the Regulation of Biotechnology. This policy describes how the U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA), and U.S. Department of Agriculture (USDA) work together to regulate the safety of GMOs.

1990s: The first wave of GMO produce created through genetic engineering becomes available to consumers: summer squash, soybeans, cotton, corn, papayas, tomatoes, potatoes, and canola. Not all are still available for sale.

2003: The World Health Organization (WHO) and the Food and Agriculture Organization (FAO) of the United Nations develop international guidelines and standards to determine the safety of GMO foods.

To produce a GMO plant, scientists first identify what trait they want that plant to have, such as resistance to drought, herbicides, or insects. Then, they find an organism (plant, animal, or microorganism) that already has that trait within its genes. In this example, scientists wanted to create insect-resistant corn to reduce the need to spray pesticides. They identified a gene in a soil bacterium called Bacillus thuringiensis (Bt), which produces a natural insecticide that has been in use for many years in traditional and organic agriculture.

In the laboratory, scientists grow the new corn plant to ensure it has adopted the desired trait (insect resistance). If successful, scientists first grow and monitor the new corn plant (now called Bt corn because it contains a gene from Bacillus thuringiensis) in greenhouses and then in small field tests before moving it into larger field tests. GMO plants go through in-depth review and tests before they are ready to be sold to farmers.

Scientists are developing new ways to create new varieties of crops and animals using a process called genome editing. These techniques can make changes more quickly and precisely than traditional breeding methods.

There are several genome editing tools, such as CRISPR. Scientists can use these newer genome editing tools to make crops more nutritious, drought tolerant, and resistant to insect pests and diseases.

Growing up in Albany, Georgia, Bryan Hallman was surrounded by agriculture but had little exposure to the industry at school. He realized he was interested in pursuing a career in agriculture during his senior year of high school when a teacher told him about the U.S Department of Agriculture (USDA) 1890 National Scholars Program.

A partnership between USDA and the 1890 land-grant universities, this program seeks to boost educational and career opportunities for students from rural or underserved communities. Scholars are provided with full tuition, fees, books, room and board, and the scholarship may also include work experience at USDA.

Plants have been instrumental for the development and establishment of Life on Earth. They provide our food and are the source of almost all energy used by mankind. Most alternative energy resources of the future are also likely to be plant-based.

The Robert H. Smith Institute of Plant Sciences and Genetics in Agriculture brings together more than 20 excellent plant scientists who study a wide range of aspects of plant biology relevant to agriculture, from the molecular and cellular levels, and all the way to the whole plant in the field. The aim of the Institute is to meet future agricultural requirements through applied and basic fundamental research in plant sciences.

Research activities in the Institute include the following areas: genetics, evolution, cellular biology, computational biology, developmental biology, plant physiology, stress physiology, ecophysiology, physiology of agricultural production and relationship between agricultural plants and their environment, agricultural genomics, precision agriculture and remote sensing, breeding, biotechnology, genome editing, applied ecology, nature preservation and management of open areas.

This textbook provides an introduction to plant genetics and biotechnology for the advancement of agriculture. A clear and structured introduction to the topic for learners new to the field of genetics, the book includes: an introduction to the life cycle of the cell, DNA and how it relates to genes and chromosomes, DNA analysis, recombinant DNA, biotechnology, and transmission genetics.

Students who major in genetics and genomics take courses in biology, chemistry, physics, statistics, and introductory genetics, and then delve into specialized genetics topics focused on humans, plants, populations, cancer, biological development, neurology, and epigenetics. They gain laboratory research experiences by taking laboratory courses and conducting independent research projects in faculty labs.

All genetics and genomics majors participate in hands-on research, which equips them with real-world skills valued by graduate and professional schools and employers. In addition to laboratory coursework, students have numerous opportunities to conduct independent research in faculty labs, where they receive mentoring from faculty, staff, and graduate students.

Students get to know faculty and instructors through small classes, and they can grow their networks by getting involved in student organizations or participating in undergraduate research experiences mentored by faculty. The Undergraduate Genetics Association, a club for students interested in genetics and genomics, provides professional development, volunteer, and social opportunities for members. The Pre-Genetic Counseling Organization, a club for students interested in genetic counseling, specializes in bringing counseling opportunities and information to undergraduates. Students can also participate in the Genetics and Genomics Peer Mentorship Program, which connects incoming students with those further along in their college careers.
