Fig. 5: Distribution of orphan genes and transcription factors in Theaceae.
From: Genome assembly of Stewartia sinensis reveals origin and evolution of orphan genes in Theaceae
A Gene duplication and family dynamics: This panel shows gene duplication (GD) counts above the horizontal line, with “+” symbols indicating gained gene families, “-” symbols for lost gene families, and “N” marking nodes in the evolutionary species tree. B Proportion of orphan genes in ancestral nodes and species: The bar graph illustrates the proportion of orphan genes in ancestral nodes and individual species. The numbers on the right detail the count and percentage of orphan genes and TFs in each sample relative to the total gene count. C Protein sequence length distribution of orphan genes and TFs in 13 Theaceae plants. The left side presents phylogenetic relationships, the middle shows median protein sequence lengths for each group, and the right side depicts the distribution of protein length within each Theaceae plant. An independent sample t-test was performed, with ****P < 0.0001 indicating statistical significance. D Exon length distribution. E Exon numbers in orphan genes and TFs. The horizontal axis representing the number of genes and the vertical axis showing the number of exons per gene. F GC content distribution. G Isoelectric point (PI) distribution. H Domain number distribution. The purple bar with the vertical red bar on the right indicates orphan genes with at least one domain. The purple bar with the vertical blue bar on the right indicates TFs with at least one domain. The light blue bar with the vertical red bar on the right indicates orphan genes without any domain. The light blue bar with the vertical blue bar on the right indicates TFs without any domain.
