Synteny analysis in Rosids with a walnut physical map reveals slow genome evolution in long-lived woody perennials

Table 5 Pairs of walnut homoeologous chromosomes and predicted structure of the eight ancestral chromosomes in terms of Jr-Vv SBs

Walnut homoeologues		Ancestral chromosome structure^a
Jr1	Jr10	Vv7, Vv11, (Vv5)^b, Vv12, Vv7,Vv 4, (Vv16), Vv14, (Vv18)
Jr2	Jr9	Vv17, Vv19, Vv2
Jr3	Jr4	Vv8, Vv10, Vv1, Vv10, Vv8
Jr5	Jr14	Vv6, (Vv15), (Vv13), (Vv15)
Jr6	Jr15	Vv18, (Vv17)
Jr7	Jr12	Vv7, (Vv4), Vv15, Vv5, Vv9, Vv15, Vv13
Jr8	Jr11	Vv4, Vv11, Vv18, Vv7, Vv14
Jr13	Jr16	Vv16, Vv1, Vv3, Vv12

^aThe tips of the short arms are to the left
^bSBs in parentheses were present in only one of the two Jr homoeologues but were not detected anywhere else in the genome, and we therefore assumed to be deleted from the other homoeologue
