Fig. 4From: Genome-wide analysis of the cellulose synthase-like (Csl) gene family in bread wheat (Triticum aestivum L.)Structural features and phases of intron evolution of the CslD subfamily genes. Drawn to scale, exons are represented by red boxes and introns by back lines. Corresponding phases of intron evolution (0, 1, and 2) for the CslD genes are shown on the top of the black linesBack to article page
