Phylogenetic relationships, gene structures, and analysis of domains and conserved motifs of the T. pseudonana chitinases. a Phylogenetic tree of 24 T. pseudonana chitinase proteins. b Gene exon/intron organization and domain distribution of the T. pseudonana chitinases. Grey lines represent introns, and the numbers 0, 1, and 2 represent their splicing phases. Yellow boxes represent untranslated regions (UTRs), and green boxes represent coding sequences (CDSs). Five chitinase-related domains, Glyco_hydro_19, Glyco_hydro_18, Chitin_bind_1, CBM_14, and LPMO_10, are indicated with orange, blue-green, magenta, grey, and salmon boxes, respectively, in the CDS translated regions. The lengths of exons and introns can be inferred by the scale at the bottom. c Distribution of conserved motifs in the T. pseudonana chitinases. Twenty putative motifs are indicated with different coloured boxes. Table S2 presents details of the motifs
