The Plant Genome Mapping Laboratory (PGML) [1] is a department of the University of Georgia, directed by Dr. Andrew H. Paterson.Research focuses on the study of major crop species such as sorghum and cotton, as well as other species such as Bermuda Grass, Brassica and Peanut.
As of 2002, the number of classified green plant species was estimated to be around 370,000, however, there are probably many thousands more yet unclassified. [10] Despite this number, very few of these species have detailed DNA sequence information to date; 125,426 species in GenBank, as of 11 April 2012, [11] but most (>95%) having DNA sequence for only one or two genes. "...almost none of ...

The 156 kb plastome gene map of Nicotiana tabacum. The 154 kb plastid genome map of a model flowering plant (Arabidopsis thaliana: Brassicaceae). The highly reduced, 27 kb plastome map of the parasitic Hydnora visseri. A plastome is the genome of a plastid, a type of organelle found in plants and in a variety of protoctists.
There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
When printed, the human genome sequence fills around 100 huge books of close print. Genome projects are scientific endeavours that ultimately aim to determine the complete genome sequence of an organism (be it an animal, a plant, a fungus, a bacterium, an archaean, a protist or a virus) and to annotate protein-coding genes and other important genome-encoded features.

TILLING (Targeting Induced Local Lesions in Genomes) is a method in molecular biology that allows directed identification of mutations in a specific gene.TILLING was introduced in 2000, using the model plant Arabidopsis thaliana, and expanded on into other uses and methodologies by a small group of scientists including Luca Comai.
A genetic map was constructed to anchor the assembled genome. 72.8% of the assembled sequences were successfully anchored onto the seven chromosomes. Another plant genome that combined NGS with Sanger sequencing was the genome of Theobroma cacao, 2010, [34] an economically important tropical fruit tree crop and the primary source of cocoa. The ...
