In the 2013–2014 growing season, field surveys were conducted in native corn fields located in high altitude agricultural communities in the ‘Sierra Norte de Puebla’ in Mexico. Symptoms typical of maize bushy stunt (MBS) disease were observed and DNA extracted from symptomatic native corn plants was used as template to confirm the presence of phytoplasmas.(More)
Catharantus roseus, known as periwinkle, is highly susceptible to phytoplasma infection. Periwinkle plants showing proliferation symptoms were detected during 2013–2014 in four geographically distant states in Mexico. The presence of phytoplasmas was confirmed through the amplification of 16S F2nR2 and cpn60 UT sequences from symptomatic plants. Sequencing,(More)
Papaya bunchy top (PBT) disease has been associated with Rickettsia-related proteobacterium. To study the occurrence of this proteobacterium in Cuba, during 2012, we collected 264 samples from asymptomatic and symptomatic papaya trees in three regions of Cuba. Symptomatic tissue evaluated by transmission electron microscopy revealed Rickettsia-like(More)
