Gene models of the PpKAI2L gene family showing the catalytic triad
and position of crRNAs. Genes are presented as organized in subclades. Exons are
displayed as grey boxes, introns and UTRs are depicted as thin black lines. Start and
stop codons are written in bold, while plain text indicates the start/end position for
each feature relative to the start codon. Only 5′-UTRs are not represented true to
scale. Transcript versions that were used are V3.1 (downloaded from the Phytozome
website in September 2019) for all PpKAI2L genes except for
PpKAI2L-B, PpKAI2L-H, and
PpKAI2L-M (V3.2). Regions targeted by crRNAs are indicated as black
inverted triangles, with their names written in bold italics. Light blue, orange, and
light green bands represent the codons for the S, D, and H residues of the catalytic
triad, respectively (see Supplemental Table S3 for reference sequences).
