Molecular characterization, vector identification and sources of phytoplasmas associated with brinjal little leaf disease in India.

ABSTRACT: Brinjal little leaf (BLL) is a widespread disease of phytoplasma etiology in India that induces severe economic losses. Surveys were conducted in eight brinjal-growing states of India during July 2014 to September 2015 and eighteen BLL samples showing little leaf, phyllody and witches' broom symptoms were collected for phytoplasma identification. Presence of phytoplasmas was confirmed in all the eighteen BLL samples using polymerase chain reaction with phytoplasma-specific primer pairs (P1/P6, R16F2n/R16R2). Pair wise sequence comparison and phylogenetic relationship of 16S rRNA gene sequences of BLL phytoplasma strains confirmed that sixteen out of eighteen BLL strains belonged to clover proliferation phytoplasma (16SrVI) group and two BLL strains (GKP-A and GKP-B) from Gorakhpur, Uttar P
