Comments P.67 right column 2nd paragraph: "Long intergenic non-coding RNAs (lincRNAs), (longer than 200nt), are defined as transcripts that lack an open reading frame of more than 100 amino acids, are located at least 500 bp away from annotated protein coding genes on the chromosome, and encode no transposable elements (primary source)." P.68 left column bottom paragraph: "Thus far, over 6,000 lincRNAs have been identified by a strict systematic search for only lincRNAs (primary source). As with mammals, in plants it has been shown that lincRNAs are more lowly expressed (about 30–60 times lower than mRNAs in Arabidopsis) than mRNA transcripts and that they are most highly expressed at the level of specific tissues (primary source)."
