Table 2. Genomic Distribution of Antisense-Oriented PATs in the Wild Type and oxt6 Mutant.

	The Wild Type			oxt6
Classa	PAT No.b	aPAT (%)c	tPAT (%)d	PAT No.	aPAT (%)	tPAT (%)
Overlapping	1,208,188	94	24.00	2,669,472	97.0	25.00
Nearby	53,652	4.1	0.70	51,972	1.9	0.31
Orphan	23,943	1.9	0.80	22,574	1.1	0.35

^aClassification of the gene or transcription unit associated with an antisense PAC. Overlapping, antisense-oriented PACs associated with overlapping, convergently transcribed genes. Nearby, antisense PACs that lie downstream from nearby, convergently transcribed genes. Orphan, antisense PACs that cannot be associated with identifiable transcription units.

^bTotal number of curated antisense-oriented poly(A) site tags that map to the respective class.

^cPercentage of all antisense PATs in the respective genetic background (the wild type or oxt6) that fall within the indicated regions. Wild-type and oxt6 PAT totals were calculated separately.

^dPercentage of total (sense + antisense) PATs that are antisense and fall within the indicated regions. Wild-type and oxt6 PAT totals were calculated separately.
