Fig. 2From: Characterization and comparative profiling of the small RNA transcriptomes in two phases of flowering in Cymbidium ensifolium Length distribution of small RNA in four libraries derived from two C. ensifolium flowering phases. A1 and A2: two PS1 libraries from flowering phase I, D1 and D2: two PS1 libraries from flowering phase II. The unigenes are grouped from 17Â nt to 30Â nt with each column representing the number of unigenes of that specific lengthBack to article page
