These phytoplasmas groups and strains were: group 1, sweetpotato witches' broom, mainland China strain of sweetpotato witches' broom, peanut witches' broom and Ipomoea obscura witches' broom; group 2, loofah witches' broom; group 3, elm yellows; group 4, rice yellow dwarf and sugarcane white leaf disease; group 5, New Jersey strain of aster yellows and western strain of aster yellows.

Species in the genus Thinopyrum are important wild relatives for wheat improvement. They possess many desirable traits such as drought, cold and salt tolerance, long spikes and more florets, high protein concentration. It has also been found that some species are the source of resistance genes for rust and powdery mildew, and especially, the source of resistance to wheat streak mosaic virus and barley yellow dwarf virus .
