    species. The results indicate a species-specific evolution of RGCs in coconut palm. However, strikingly similar RGCs between species of ArecalesarecalesSubject Category: Organism Names

    indicate a high conservation of specific RGCs of this family, suggesting a monophyletic origin of three genera. The phylogenetic relationship between RGCs of Arecales and BrassicalesbrassicalesSubject Category: Organism Names

    suggests that these sequences possibly emerged before being divided between monocots and dicots. Finally the comparative analysis of the expression of four RGCs in healthy coconut palm and those affected with lethal yellowing disease revealed differences in their expression profiles. This study provides new insights for future efforts towards the improvement of disease resistance in coconut palm and other species of Arecaceae.
