Identification of a non‐coding motif in the upstream region of the start codon associated with gland cell expression in Pratylenchus penetrans. (A) Each bar shows the distribution of the motif within 500 nucleotides upstream of the start codon. The annotation of each transcript can be found in Table 3. (B) Graphic representation of the consensus motif sequence. (C) In related plant‐parasitic nematodes with well‐annotated genomes available (Meloidogyne hapla and Globodera pallida), the number of promoter regions with multiple copies of this motif does not deviate from random. Normal promoter regions are shown in blue for M. hapla and red for G. pallida; 250 iterations of randomization of the sequence of each promoter region are shown in grey. (D) An increased number of motifs in the promoter region does not correlate with a greater chance of the corresponding gene encoding a predicted signal peptide in either species.
