Association of phytoplasmas and viruses with malformed clovers
Original language description
Plants of Trifolium spp. exhibiting two different kinds of symptoms - phyllody associated with yellowing/reddening, and dwarf growth habit without floral abnormalities - were observed in several areas of the Czechia. Nested polymerase chain reaction (PCR) with phytoplasma specific primers, and restriction fragment length polymorphism (RFLP) analyses of 16SrDNA revealed that phyllody of T repens was associated with phytoplasmas belonging to the 16SrI-C subgroup. Similar symptoms in T hybridum and T pratense plants revealed the presence of phytoplasmas belonging to two subgroups: 16SrI-C and 16SrIII-B. Dwarf disease of cultivated T pratense plants was associated with more than one agent: I I of 20 plants examined by PCR/RFLP analysis revealed the presence of phytoplasmas belonging to four distinct subgroups: 16SrI-B, 16SrI-C, 16SrIII-B and 16SrX-A. Moreover, two kinds of bacilliform virions were observed in ultrathin sections of 15 T pratense plants.
