Global identification and analysis of long non-coding RNAs in diploid strawberry Fragaria vesca during flower and fruit development

Table 1 The number of lncRNAs in different classes before and after filtering

	Isoform		Locus
Class-code	Before^a	After^b	Before^a	After^b
u (unknown or intergenic region)	7,203	3,763	4,726	2,575
o (overlapped with existed gene with a dramatic difference in gene structures)	5,125	625	2,824	464
x (overlapped with existed gene in an opposite direction)	2,658	1,471	1,438	902
i (located in introns)	41	25	40	24
Total	15,027	5,884	8,709^c	3,862^c

Notes:
^aThe number of original isoforms and loci predicted by Cufflinks
^bThe number of lncRNAs after filtering
^c“Total” number is smaller than the sum of the column, because certain loci have multiple isoforms with different class codes
