Fig. 1: Identification of insect lncRNAs and factors influencing lncRNA quantity.
From: The landscape and evolutionary dynamics of derived lncRNAs in insects
A Phylogenetic distribution of lncRNA types across 115 insect species representing 10 orders. Bar colors represent different lncRNA types, and the height indicates the total count of identified lncRNAs per species. The tree indicates phylogenetic relationships among the species. B Saturation curves showing cumulative lncRNA numbers plotted against increasing transcriptome sample sizes (increments of 50) for four representative species: A. pisum (pea aphid, n = 694), A. mellifera (honey bee, n = 2362), B. mori (silkworm, n = 1344), and T. castaneum (red flour beetle, n = 1113). C Strong positive correlation between genome size and lncRNA abundance (R = 0.927, P < 0.001) among species with >500 transcriptomes. Scatter plot displays genome size (x-axis, in Mb) versus total lncRNA count (y-axis). Each point represents a species, with regression line and confidence interval shown. D Significant positive correlation between lncRNA abundance and genomic TE content (R = 0.510, P < 0.05) among species with >500 transcriptomes. Scatter plot shows the percentage of genome covered by TEs (x-axis) versus total lncRNA count (y-axis). Each point represents one species, with regression line and confidence interval shown.
