Fig. 5From: Evolutionary characterization and transcript profiling of β-tubulin genes in flax (Linum usitatissimum L.) during plant developmentN-terminal and C-terminal sequence alignment of flax β-tubulins. Aminoacid sequences were aligned with Clustal W. Background color code: Yellow: identical; green: block of similar; light blue: conserved; white: non-similar. B: beta-sheet; H: alpha helix. (a) Amino-terminal region, from residues 1 to 103. (b) Carboxy-terminal region, from residue 350 to 452. CTT: C-terminal tailBack to article page
