Fig. 3From: Genome-wide analysis of WOX genes in upland cotton and their expression pattern under different stressesCollinearity analyses within G. hirsutum. The ends of blue lines link two genes from the homologous chromosome pairs in At and Dt sub-genomes, respectively, showing the orthologous pairs that diverged from a same ancestor. The green line links two duplicated genes locating in non-homologous chromosome pair in At and Dt sub-genomes. The ends of the red lines link the homologous pairs formed by segmental duplication within the At- and Dt-subgenomes. A01 to A13 represent the chromosomes in At sub-genome and D01 to D13 represent the chromosomes in Dt sub-genome.Back to article page
