Plant conservation. Germplasm resources, Plant. Plant biotechnology. Biotechnology -- methods. Plants -- genetics. Summary "The tools of contemporary biotechnology, such as molecular biology, tissue culture and cryopreservation are being increasingly applied to assist the international conservation of plant diversity.

Plant Conservation Biotechnology introduces biotechnological techniques which are currently used to conserve horticultural and crop plant germplasm, forest tree genetic resources, endangered plant species, and plant cell culture collections.

A germplasm holds information on the genetic makeup of the species. Scientists evaluate the diversity of plant germplasms to find ways on how to develop new better yielding and high quality varieties that can resist diseases, constantly evolving pests, and environmental stresses. Molecular markers are used to map out the genetic base of crops and select favorable traits to come up with a better germplasm for growers. Molecular markers are short strings or sequence of nucleic acid which composes a DNA segment that are closely linked to specific genes in a chromosome.

Thus, if the markers are present, then the specific gene of interest is also present. Marker-assisted selection MAS such as single nucleotide polymorphisms SNPs , is widely used in different agricultural research centers to design genotyping arrays with thousands of markers spread over the entire genome of the crops. After observing the desired traits in selected plants, these are then incorporated through modern or conventional breeding methods in existing crop varieties.

Generated plants with the desired trait may be tested in the field for agronomic assessment and resistance screening against pests and diseases. Selected plants plants will be multiplied through tissue culture and other techniques. Recent advances in genomic, proteomic and metabolomic research offer unique opportunities for the search, identification, and commercial utilization of biological products and molecules in the pharmaceutical, nutraceutical, agricultural, and environmental sectors.

To come up with effective conservation management programs for endangered crop varieties, it is important to evaluate their genetic relatedness and distances from other relatives. Such information could be derived through DNA profiling commonly conducted through electrophoresis.

About this book

Through this method, an individual organism is identified using unique characteristics of its DNA. These areas contain repetitive sections of a sequence called short tandem repeats STRs. Organisms inherit different numbers of repeated sequences from each parents and the variation in the number of repeats within an STR lead to DNA of different lengths.
