The sequence of the genome of "Candidatus Tremblaya princeps" strain PCVAL, the primary endosymbiont of the citrus mealybug Planococcus citri, has been determined. "Ca. Tremblaya princeps" presents an unusual nested endosymbiosis and harbors a gammaproteobacterial symbiont within its cytoplasm in all analyzed mealybugs. The genome sequence reveals that "Ca. Tremblaya princeps" cannot be considered an independent organism but that the consortium with its gammaproteobacterial symbiotic associate represents a new composite living being.
已确定了“柑橘粉蚧原内共生菌”PCVAL 菌株,即柑橘粉蚧的主要内共生体“Candidatus Tremblaya princeps”的基因组序列。“Candidatus Tremblaya princeps”呈现出一种不寻常的嵌套内共生关系,在所有分析的粉蚧中,其细胞质内都寄生着一种γ-变形杆菌共生体。基因组序列表明,“Candidatus Tremblaya princeps”不能被视为独立的生物体,而是与其γ-变形杆菌共生体伙伴组成的联合体代表了一种新的复合生命体。
