Progress in Cotton Functional Genomics and structural Genomics

Cotton functional genomics promise to enhance the understanding of fundamental plant biology to systematically exploit genetic resources for improvement of cotton fibre quality and yield, as well as utilization of genetic information for germplasm improvement. However, determining the cotton gene functions is a much more challenging task which has not progressed at rapid pace. Genome sequencing technologies has been improved with exponent pace,and some species such as G.raimondii, G.arborem, G.hirsutum,G.barbadense have been sequenced. but precise chromosome-scale assembling of genomes remained an important challenge.This paper presents a comprehensive overview on the recent tools and resources available with the major advances of cotton functional genomics to develop elite cotton genotypes ,and we generated significantly correct high quality assembly of G. arboreum single chromosome by genetic map and reference assisted approaches.
