Prediction of trans-antisense transcripts in Arabidopsis thaliana.

ABSTRACT:

Background

Natural antisense transcripts (NATs) are coding or non-coding RNAs with sequence complementarity to other transcripts (sense transcripts). These RNAs could potentially regulate the expression of their sense partner(s) at either the transcriptional or post-transcriptional level. Experimental and computational methods have demonstrated the widespread occurrence of NATs in eukaryotes. However, most previous studies only focused on cis-NATs with little attention being paid to NATs that originate in trans.

Results

We have performed a genome-wide screen of trans-NATs in Arabidopsis thaliana and identified 1,320 putative trans-NAT pairs. An RNA annealing program predicted that most trans-NATs could form extended double-stranded RNA duplexes with their sense partners. Amo
