Spartium witches'-broom (SpaWB), buckthorn witches'-broom (BWB) and allocasuarina yellows (AlloY) are witches'-broom and yellows diseases of Spartium junceum (Spanish broom), Rhamnus catharticus (buckthorn) and Allocasuarina muelleriana (Slaty she-oak), respectively. These diseases are associated with distinct phytoplasmas. The SpaWB, BWB and AlloY phytoplasmas share <97.5 % 16S rDNA sequence similarity with each other and with other known phytoplasmas, including the closely related phytoplasmas of the apple proliferation group. Also, the SpaWB, BWB and AlloY phytoplasmas each have a different natural plant host. Based on their unique properties, it is proposed to designate the mentioned phytoplasmas as novel 'Candidatus' species under the names 'Candidatus Phytoplasma spartii', 'Candidatus Phytoplasma rhamni' and 'Candidatus Phytoplasma allocasuarinae', respectively.
鹰爪豆丛枝病（SpaWB）、鼠李丛枝病（BWB）和木麻黄黄化病（AlloY）分别是鹰爪豆（西班牙金雀花）、鼠李（药炭鼠李）和多枝木麻黄（灰木麻黄）的丛枝病和黄化病。这些病害与不同的植原体有关。SpaWB、BWB和AlloY植原体彼此之间以及与其他已知植原体（包括苹果增殖组的密切相关植原体）的16S rDNA序列相似性均小于97.5%。此外，SpaWB、BWB和AlloY植原体各自具有不同的天然植物寄主。基于它们的独特特性，建议将上述植原体分别命名为新的“候选”物种，即“候选植原体鹰爪豆种”、“候选植原体鼠李种”和“候选植原体木麻黄种”。
