简介
Accumulating evidence suggests that that non-coding RNAs (ncRNAs) play key roles in gene regulation and may form the basis of an inter-gene communication system. Many ncRNAs are synthesized similar to mRNAs and can be detected through screening of polyA-rich EST or cDNA libraries. We developed a computational pipeline to screen EST and genomic sequence data for those transcribed genes with limited protein coding potential and applied this pipeline to the model legume Medicago truncatula. This process identified a set of 503 mRNA-like transcripts that appear not to encode proteins. Further computational analysis showed that many of these ncRNA candidates share structural similarities to known ncRNAs and that they clearly differ from protein coding genes and non-transcribed regions in their base and oligonucleotide compositions, as well as in aspects of secondary structure. By using a …
