We identified AOX2 genes in monocot species from Lemnoideae (Spirodela polyrhiza, Lemna gibba and Landoltia punctata), Pothoideae (Anthurium andraeanum and Anthurium amnicola) and Monsteroideae (Epipremnum aureum) subfamilies within the Araceae, an early-diverging monocot family. These findings highlight the presence of AOX2 in the most ancient monocot ancestor and also that at least partial loss of this gene occurred during speciation events within several monocot orders. The presence of AOX2 in monocot species challenges (1) new understanding of the evolutionary history of the AOX gene family in angiosperms and (2) drives experimental and bioinformatics efforts to explore functional relevance of the two AOX gene family members for plant growth and development. Knowledge gain in this field will impact running strategies on AOX-derived functional marker candidate development for plant breeding.
