Abstract: ´Candidatus Phytoplasma australiense' occurs in New Zealand and Australia where it is associated with plant diseases in native, weed and crop plants. Between January 2009 and July 2010, four new diverse hosts of `Ca. P. australiense' have been identified in New Zealand: potato, Jerusalem cherry, swan plant and celery, as well as a new disease association in boysenberry. A 1.2 kb region of the 16S rRNA gene of the phytoplasma amplified from the new hosts were identical to each other. Partial tuf gene sequence analysis of 29 strains from the new plant hosts revealed that they belong to two separate subgroups, tuf variant VII and tuf variant IX. Two of the strains, one from potato and the other from celery, contained a mixed infection of both phytoplasma subgroups.
