Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [ 1 ] [ 2 ] It is generally considered a field of biology and botany , but intersects frequently with many other life sciences and is strongly linked with the study of information systems .
A key event in the conservation of plant genetic resources was the establishment of the International Board for Plant Genetic Resources (IBPGR) (now Bioversity International) in 1974, whose mandate was to promote and assist in the worldwide effort to collect and conserve the plant germplasm needed for future research and production. IBPGR ...
Germplasm, genetic resources that are preserved for various purposes such as breeding, preservation, and research; International Treaty on Plant Genetic Resources for Food and Agriculture, an international agreement to promote sustainable use of the world's plant genetic resources; Genetic resources contribute to the provisioning ecosystem ...
Studied R genes usually confer specificity for particular strains of a pathogen species (those that express the recognized effector). As first noted by Harold Flor in his mid-20th century formulation of the gene-for-gene relationship, a plant R gene has specificity for a pathogen avirulence gene (Avr gene). Avirulence genes are now known to ...
The International Treaty on Plant Genetic Resources for Food and Agriculture [2] (also known as ITPGRFA, International Seed Treaty or Plant Treaty [3]) is a comprehensive international agreement in harmony with the Convention on Biological Diversity, which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources for food ...
The U.S. National Plant Germplasm System (NPGS) is a network of institutions and agencies (federal, state and private) led by the Agricultural Research Service (ARS) of the U.S. Department of Agriculture in the effort to conserve and facilitate the use of the genetic diversity of agriculturally important plants and their wild relatives.
The wise use of crop genetic diversity in plant breeding and genetic modification can also contribute significantly to protecting the biodiversity in crops. Crop varieties can be genetically modified to resist specific pests and diseases. For example, a gene from the soil bacterium Bacillus thuringiensis (Bt) produces a natural insecticide toxin.
The Plant Genome is a triannual peer-reviewed scientific journal covering all aspects of plant genomics. It is published by Wiley on behalf of the Crop Science Society of America . Since 2013, it is available online only.
