6. Selected Seed BACs  Marker-specific amplification by PCR and sequence verification  Location on Chr9 confirmed by : FISH only: 2 Sequencing Ils only: 6 FISH and sequencing Ils: 7  Verified BEs (if possible)  We selected 15 seed BACs: Arrows show aproximate BAC location based on Tomato-EXPEN 2000 map Big GAP: 36 cM without seed BACs Distance between some BACs: 2 cM Uneven distribution Tomato Sequencing Meeting PAG XV 2007 San Diego, 14 January 2007

7.  BLASTN against BAC end sequence database at Cornell University No candidates found in some cases Too large overlaps in some cases  FPC data from Hind III and Mbo I libraries at Sanger Institute Some of our BACs are not in a FPC contig FPC contigs are too poor to find good candidates in some cases Selection of extension BACs  Selection is based on: Tomato Sequencing Meeting PAG XV 2007 San Diego, 14 January 2007
