Abstract

Little leaf and witches’ broom symptoms were observed on Tecoma stans plants at the AND University campus, Ayodhya, India, during 2021–2022. A 1,250 bp product was amplified from DNA extracted from symptomatic T. stans plant samples subjected to nested PCR assays with P1/P7 and R16F2n/R16R2 primers. Sequence analysis of the 16Sr RNA gene product through phylogeny and virtual RFLP analyses of the T. stans phytoplasma strain allowed its identification as ‘Candidatus Phytoplasma australasia’ (16SrII-D). This is a first record of phytoplasma presence in T. stans.
