Plant genomes genome sequence

Since the commercial introduction of biotech crops, a need has emerged for analytical methods capable of detecting the novel DNA sequences introduced into the plant genome and also methods for detecting the protein products expressed by the... 

DNA construct will often contain an effect gene and a selectable marker gene (such as antibiotic or herbicide resistance), both of which are bracketed by promoter and terminator sequences. A plasmid vector carries this cassette of genetic information into the plant genome by one of the above methods.

Rice is the most important staple food crop in the world and has also emerged as the model cereal species (it is the only terrestrial plant other than Arabidopsis thaliana to benefit from a completed genome sequence, and extensive EST resources are also available). Rice has a lower annual grain yield than maize (6600 kg ha-1) and the grain has a lower protein content (8%), but like maize it is easy to transform and manipulate in the laboratory, a range of useful expression cassettes have been devel-... 

Fourthly, ecological and economic issues have proved important factors in selection of species for genomic sequencing. The weed Arabidopsis is not only an important experimental species for plant biologists but also plants in general are of enormous importance to us. Getting the rice, Oryza, genome was driven by the commercial importance of this plant as a key component of the human diet. 

Plant genome projects, notably the rice genome project, have also attracted large companies, like Monsanto, Novartis, and DuPont. Arabidopsis thaliana, a brassicacean plant that has become a model in plant genetics, was the first flowering plant to have the genome sequence completed Arabidopsis Initiative 2000).
