Fig. 2From: Evolutionary characterization and transcript profiling of β-tubulin genes in flax (Linum usitatissimum L.) during plant developmentExon/intron structure of flax β-tubulin genes. cDNA sequences were aligned to their putative genomic counterparts, listed in Table 1. Only a short sequence corresponding to LusTub7c was found in the NCBI database (dotted line indicates the missing part)Back to article page
