Comparative analysis of a plant pseudoautosomal region (PAR) in Silene latifolia with the corresponding S. vulgaris autosome

Table 3 GC and GC3 content comparison

Gene name	ESP1	BIP1	ACBP1	PAR1	PAR2
Sl sequence length (bp)	5416	2013	1125	2049	507
Sl exon GC content (%)	42.4	47.3	48.3	42.3	48.3
Sl exon GC3 content (%)	41.2	53.5	42.9	38.1	49.7
Sv sequence length (bp)	5416	2013	1125	2049	507
Sv exon GC content (%)	42.4	47.3	47.7	42.4	48.3
Sv exon GC3 content (%)	41.1	53.7	42.9	37.3	49.1
Sl putative gene GC content*	38.2	42.3	38.8	40.4	39.9
Sv putative gene GC content*	37.5	42.8	39.2	40.2	40.6

Sl: Silene latifolia, Sv: S. vulgaris.
*Exon and intron sequences were taken into account.
GC and GC3 contents were computed on gene sequences of identical size in both S. latifolia and S. vulgaris. PAR2 is truncated in the BAC sequence of S. latifolia and ESP1 is truncated in S. vulgaris. In these cases, only partial sequences with coverage in both species were compared.
