Prunus blocks that match to more than one site in the Populus genome. The two conserved syntenic groups are selected when more than three Prunus sequences had matches with two different regions in Populus or Arabidopsis. (A) A region in G5 of the Prunus TxE map matches to regions in LG_II and LG_XIV. (B) A region in peach BAC contig ctg468 matches to regions in LG_II and LG_V. Also shown is a block in peach BAC pPn31C7 that is syntenic to regions in LG_II and LG_V, each region is 1.7 Mb apart from the corresponding region that is syntenic to ctg468. The approximate base pair length in peach genome of the syntenic region in genetic and physical map is calculated from the TxE map size 524 cM [39] and the peach genome size 290 Mb [43], and the total physical length of the peach physical map, 303 Mb, [29] and the total unit length of the BAC contigs, 242772.
