Overview | Consensus map | People | Publications | Further Information


We have made the world's most detailed molecular map of the cotton genome, and have applied the map to gain a better understanding of many traits important to domestication and improvement of CottonFiber. Some of our present activities include:

  • We have assembled a 'consensus' genetic map from the most detailed diploid and tetraploid maps (respectively) that we know of, to one another and also to the Arabidopsis genome sequence (Rong et al 2005, Genome Research 15:1198-1210). In addition, we have aligned 11 additional lower-density maps and 432 QTLs associated with these maps, permitting meta-analysis of the QTL landscape of cotton for a number of traits (especially fiber-related ones) (Rong et al 2007, Genetics 176:2577-88). These resources are available from our CMAP site.
  • Building a physical map of cotton that is suitable as a framework for sequencing the cotton genome (see PGML Cotton Genome Database site).
  • Better understanding how genetic diversity is arranged in the cotton genome, and how different measures of diversity are interrelated.
  • Partnering with breeders to bring new diversity into the cotton gene pool from wild relatives, taking advantage of natures solutions to many problems that face cotton producers.
  • Better understanding the role of polyploidy in the evolution of productive crops.
