The sandal spike disease of sandalwood is known to be associated with aster yellows (AY) phytoplasmas and is a prime threat to sandalwood cultivation in India. The Marayoor Sandalwood Reserve (Kerala state) has an excellent collection of naturalised and matured sandalwood trees and therefore sandalwood forest were surveyed and symptomatic samples were collected from this area. The study confirmed the disease association with AY phytoplasmas and allow to verify the presence of a novel AY phytoplasma strains indicating that phytoplasma strains are differentiating with their plant host species and geographic regions.
