BMC Genomics

Table 1 The occurrence of alternative splicing events in Volvox in comparison to Chlamydomonas , Arabidopsis and human

Organism	Total number of included ESTs/cDNAs	Alternative splicing [%]	Exon skipping [%]	Intron retention [%]	Alternative 5′ splice site [%]	Alternative 3′splice site [%]
Volvox carteri ^1*	132,038	2.9	9.5	46.5	17.9	21.9
Chlamydomonas reinhardtii ^2**	252,484	3	11.9	50.0	11.6	25.8
Arabidopsis thaliana ³	541.594	20	3	41	18	38
Human^4***	435 million cDNA reads	90	40	3	8	18

¹ this study, ²[53], ³[26],⁴[16, 134].
*4.2% show other alternative splicing events.
**0.7% show both alternative 5′ splice site and alternative 3′ splice sites.
*** 32.7 % show other alternative splicing events such as exclusive exon, alternative first exon, alternative last exon and tandem 3′ UTR.
