- 227 single nucleotide substitutions were made to the assembly sequence based on re-sequencing data provided by Richard Clark (Ossowski et al. 2008) and Joe Ecker.
- 341 indels were made to the assembly sequence based on re-sequencing data provided by Richard Clark and EST and cDNA sequences deposited in Genbank that supported the insertion/deletion.
- 14 regions previously identified in TAIR8 as either vector, E.coli or rice contamination, and where the existing sequence had been substituted with the equivalent number of IUPAC ambiguity code 'N's were standardized (via deletion) to a set size of 100bp.
- All five nuclear chromosomes were updated for TAIR9 details of the golden path length of each chromosome can be found at http://www.arabidopsis.org/portals/genAnnotation/gene_structural_annotation/agicomplete.jsp here.
Further details of these assembly changes and earlier TAIR8 updates can be found at ftp://ftp.arabidopsis.org/home/tair/Sequences/whole_chromosomes/ Assembly updates and gap information can also be viewed in TAIRs GBrowse (see Assembly tracks section).
