Plant Genome -

Genetically, a plant genome is the most complex one found in living systems. It comprises three interacting genome. Aside from the nuclear genome, complete genetic systems are located in the plastids and the mitochondria. These organelles are semiautonomous bodies; they have their own organizational and functional properties but do not synthesize all their own proteins. The nuclear genome plays an important role in organelle biogenesis.

Techniques in molecular cloning and deoxyribonucleic acid (DNA) sequencing have provided the tools for studying the structure of genes at the nucleotide level. Hence our knowledge of the structure, organization and expression of a plant genome has come largely through, the use of recombinant DNA techniques. This technology allows isolation and characterization of specific pieces of DNA by cloning the DNA sequences into bacterial cells in which they can be replicated and large quantities obtained for analysis.
