Fig. 1. Global comparative analysis of lncRNAs among 37 species.
a Plot of lncRNA characteristics, including the following: I, the lncRNA number; II, the mean length; III, the median length; IV, the mean exon number; V, the mean expression value; and VI, the median expression value. b Violin plots and boxplots of log2(FPKM+1) values of lncRNAs with an FPKM<2 in all species. c Violin plots and boxplots of the log10(length) values of lncRNAs in all species
