The international research team led by Chinese Academy of Agricultural Sciences and BGI have completed the genome sequence and analysis of a diploid cotton— Gossypium raimondii. The cotton genome provides an invaluable resource for the study and genetic improvement of cotton quality and output, and sheds new lights on understanding the genetic characteristics and evolutionary mechanism underlying cotton and its close relatives. The study was published online in Nature Genetics.
Cotton, also known as "white gold", is an important cash crop worldwide. Its fiber is one of the oldest fibers under human cultivation, which traces over 7,000 years old recovered from archaeological sites. The cotton production provides income for approximately 100 million families, and approximately 150 countries are involved in cotton import and export. Additionally, in scientific research, cotton also serves as an excellent model system for studying polyploidization, cell elongation and cell wall biosynthesis.
