Molecular characterisation was performed on phytoplasma strains collected in Semberia region of Bosnia
and Herzegovina from symptomatic maize, pepper and celery and resulted infected with’Ca, P solani’, by
a multigene RFLP and sequeocing study. The RFLP analyses on tuf, secY, vmpl and stamp genes allow to
differenliate 8 lineages in the 13 positive samples obtained, indicating the presence ofdifferent’Ca. P. solani’
Jineages. Three ) ineages were detected in the seven samples of maize, each of the four pepper sanples was
infected by a different lineage, and one ofthese was also found in one ofthe two ceLery samples. The phytoplasmas
in the other celery sanpLe represent a further lineage. The identiflcation of a number of lineages in
these crops compared to the 4 detected in grapevine in previous surveys, allow to speculate about the preserce
of insect vectors that could be different in the case of these crops from those reported for grapevine or of
possible increasing ofphytoplasma biodiversity by their possible seed transmission.
