How can we conserve genetic resources?
The fundamental objective of genetic resources conservation is the maintenance of broad based genetic diversity within each of the species (i.e., intra-specific genetic diversity) with a known or potential value in order to ensure availability for exploitation by present and future generations.
Which is the conservation and management of genetic resources in their natural habitat?
In situ conservation is the on-site conservation of genetic resources in natural populations of plants or animal species such as forest genetic resources, in natural populations of tree and animal species.
Why it is needed to perform plant genetic resources conservation?
The main reasons for conserving PGRFA are to ensure the future adaptability of cultivars and wild populations; to preserve data and traits that ensure sustainable agriculture; to promote the use of genetic resources in commerce and biotechnology; to conserve genetic diversity for cultural reasons.
What is genetic resources for breeding?
Genetic diversity is the basis of plant breeding. Genetic resources – modern cultivated varieties crossed with wild relatives – serve as the starting point for developing improved varieties with new combinations of desired attributes through crossing and selection.
How can we conserve genetic diversity?
Gene banks (ex situ conservation) store seeds, semen and other reproductive material, which is crucial for the long-term conservation of genetic diversity. Maintaining breeds and varieties in situ/on farms also contributes to the conservation of genetic diversity.
What can be done to preserve the genetic diversity of plants?
Endangered species protection programs, zoos, and plant conservatories work to preserve the Earth’s animal and plant population, but in order to preserve the richness of biological diversity, alternatives such as gene banking must be used, scientist said today at the American Association for the Advancement of Science …
What is the best method to conserve genetic material of wildlife?
Ex situ conservation is the preservation and propagation of species and populations, their germ cell lines, or somatic cell lines outside the natural habitat where they occur. This method maintains the genetic diversity extant in the population in a manner that makes samples of the preserved material readily available.
What are the two types of conservation?
Conservation can broadly be divided into two types:
- In-situ: Conservation of habitats, species and ecosystems where they naturally occur.
- Ex-situ: The conservation of elements of biodiversity out of the context of their natural habitats is referred to as ex-situ conservation.
- Hotspots of biodiversity.
- Threatened Species.
What is plant conservation resources?
‘Plant Conservation is a broad group of activities which aims to prevent plants from becoming extinct. It includes the direct conservation of wild populations, collections of plants with gardens, education programmes, invasive species control, recovery and restoration work, research programmes, training…’ BGCI.
How can we conserve genetic diversity in plants?
The following set of principles can be used to guide our efforts in maximizing the diversity of our plant genetic resources.
- Preserve cultural diversity.
- Base food security on biodiversity.
- Keep small farmers on the land.
- Conserve diverse environments.
- Integrate conservation with use.
- Market development.
What are examples of genetic resources?
They include, for example, microorganisms, plant varieties, animal breeds, genetic sequences, nucleotide and amino acid sequence information, traits, molecular events, plasmids, and vectors.
