Each week PGRA provides the latest information on the genetic resources of all plant species of economic value and their wild relatives.
Plant Genetic Resources Abstracts is a fully searchable abstracts database of internationally published research.
CAB Direct (CABI’s own platform)
All crops and their wild relatives are covered including those species that have potential economic value. The concepts covered include:
Biotechnology
Use of molecular marker techniques to assess genetic diversity, e.g.
- – DNA cloning
-
- – genetic engineering
– nucleotide sequences of wild relatives
- – RFLP and RAPD, etc.
Conservation
In situ and ex situ conservation including
-
-
- – artificial seeds
– conservation by in vitro culture
- – cryopreservation of callus tissue and pollen
– on-farm conservation
-
- – seed storage (including information on seed viability and seed dormancy)
- – storage of vegetative material and pollen
Gene banks, documentation and information management
Gene banks including botanical gardens, arboreta and their activities. Crop descriptors, passport data, databases, herbaria, etc
Genetic resources, general aspects
- – general reviews
- – international agreements and other legal aspects
- – intellectual property rights
- – networks
-
- – organizations
- – policy planning
– training
Genetic diversity
-
-
- – deforestation and habitat loss
– external factors affecting structure of plant communities (e.g. by grazing, burning, logging)
- – genetic erosion
– genetic variation
-
-
- – germplasm surveys and collecting
- – loss of species diversity
- – nature reserves
– population genetics
- – population dynamics
- – reproductive biology of wild relatives
Germplasm characterization and evaluation
Morphological characterization. Screening of large germplasm collections and landraces for pest/disease resistance, yield components, and tolerance of stress/salinity
Germplasm enhancement and utilization
Introgression and hybridization of crops with wild relatives and their utilization for crop improvement
Local and traditional uses of genetic resources
Social and economic aspects of the use of plants by local communities for food, medicinal and other purposes, ethnobotany, indigenous knowledge and sustainability
Plant health, quarantine and safe movement of germplasm
Quarantine aspects relating to genetic resource conservation, germplasm exchange
Taxonomy, evolution and origin
All aspects of taxonomy, phylogeny and evolution. Geographical distribution of wild relatives including information on centres of origin, centres of diversity and biogeography of crops
