From: Transcript profiling of Populus tomentosa genes in normal, tension, and opposite wood by RNA-seq
The distribution of gene expression levels. Total reads from each of three libraries that match to the Populus gene models were plotted as integrated log2 values. The distribution is based on the number of genes in each log2 gene expression category (>0 and < =16). It revealed that most of the mRNAs are expressed at low levels, with a small proportion of mRNA that is highly expressed. Also, all three libraries have similar expression patterns.
