Numbers of 2HOM Blocks in the Examined Genomes

Species	2HOM Blocks	2HOM Blocks Filtered Same Scaffold	Categorization of 2HOM Block Duplications
			Private Duplications	Shared Duplications
P. capsici	474	98 36 (P<0.0001)	78 (77%)	23
P. cinnamomi	609	183 0	148 (80%)	37
P. infestans	396	244 70 (P<0.0001)	227 (93%)	16
P. parasitica	255	104 49 (P<0.0001)	61 (74%)	21
P. ramorum	252	145 43 (P<0.0001)	112 (84%)	22
P. sojae	282	131 62 (P<0.0001)	99 (80%)	25

Note.—The 2HOM blocks were filtered for large families and for TEs. The number of filtered 2HOM blocks with copies on the same scaffold was assessed for significance by genome randomization. Of each filtered 2HOM block, the timing of underlying duplication(s) was inferred either from phylogenetic trees or from its single-species occurrence and categorized accordingly.
