Fig. 7From: Chloroplast (Cp) Transcriptome of P. davidiana Dode×P. bolleana Lauch provides insight into the Cp drought response and Populus Cp phylogenySequence alignment of 8 related chloroplast genomes using the mVISTA program with “Shanxinyang” as a reference. Grey arrows above the alignment indicate the transcriptional directions of genes. Genome regions are colour coded as exons and conserved non-coding sequences (CNSs). A 50% identity cut-off was used for the plots. The Y-axis indicates the percent identity between 50 and 100%Back to article page
