Figure 1From: Duplication, divergence and persistence in the Phytochrome photoreceptor gene family of cottons (Gossypium spp.)Gene diagrams and PCR amplicons used in this study. Model gene structures are derived from Arabidopsis thaliana annotations (At1g09570, At2g18790. At5g35840, At4g18130). The PHYB 2.1 kb sequenced fragment represents a composite of several overlapping amplicons.Back to article page
