Why are plant scientists sequencing whole plant genomes?
What will be an ideal response?
The evolutionary origin of angiosperms and other plant groups is not well understood. The fossil
record reveals very little, and as entire genomes are sequenced the evolutionary paths by which new
plant groups arose should become clear. The process of sequencing plant genomes leads to improved
sequencing methods that advance future sequencing research. Just over 30 plant genomes have been
partially or fully sequenced, which is just a small proportion of the number of plant species that exist.
The sequencing research has and will provide important information on the genetics of disease and
pest resistance, development of vascular tissues and wood, and tolerance to drought. Sequencing of
important crops species is already leading to major insights. These important crop species include
wheat, soybean, rice, cucumber, potato, apple, orange and cacao. Obviously this research is important
and will expand.
