Figure 2.
The Wolffia genome is collinear with Spirodela with bloating and loss of genes owing to transposable elements (TEs). (A) wa8730 scaffold 1 (scf1) is collinear with wa7733 scf8. (B) Conserved core circadian clock genes PRR37 (red ribbon) and LHY (gold ribbon) on sp9509 Chromosome 20 (Chr 20) are collinear in wa8730 scf200 and wa7733 scf432. (C) WOX5 is lost in Wolffia compared to Spirodela owing to TE insertions (yellow boxes). (D) DOT3/NPH3 loci in Spirodela lost in Wolffia owing to LTR-RT insertions. Gray lines represent syntenic connections. Green and blue boxes are forward and reverse representation for genes, respectively. Orange boxes are TEs.
