Figure 4From: Transcriptome profiling in conifers and the PiceaGenExpress database show patterns of diversification within gene families and interspecific conservation in vascular gene expressionExpression classes and numbers of tissue of annotated and non annotated sequences. A-C: Number of annotated and nonannotated sequences per expression class for xylem from juvenile trees (A), roots (B) and young foliage (C). Other tissues are shown in Additional file 8: Figure S5. D: Number of tissues in which each annotated and non-annotated sequence was detected. Frequency, number of genes in a given intensity class or detected in a given number of tissues types.Back to article page
