| phylogenetic analysis identifies a 'candidatus phytoplasma oryzae'-related strain associated with yellow leaf disease of areca palm (areca catechu l.) in india. | yellow leaf disease (yld) with phytoplasmal aetiology is a serious disease of arecanut palm in india. the present study was undertaken to characterize the 16s rrna and seca gene sequences of the indian arecanut yld phytoplasma for 'candidatus phytoplasma' species assignment and 16sr group/subgroup classification. phytoplasma 16s rrna genes were amplified using three sets of semi-nested/nested primers, 1f7/7r3-1f7/7r2, 4fwd/3rev-4fwd/5rev and p1/p7-r16f2n/r16r2, producing amplicons of 491, 1150 a ... | 2013 | 22843718 |
