Symptoms of little leaf and flat stem were observed in Tinospora cordifolia plants at the medicinal block of the horticultural garden of S.V. Agricultural College, Tirupati, India. DNA was extracted from symptomatic and asymptomatic leaves and subjected to nested PCR assay with P1/P7 and R16F2n/R16R2 primers. The PCR amplified 1,250 bp product was eluted, sequenced and its analysis through phylogeny and virtual RFLP allows the identification of the presence of ‘Candidatus Phytoplasma australasia’.
