| first report of association of potato virus x and potato virus y and 'candidatus phytoplasma trifolii' in brinjal in india. | symptoms of little leaf, leaf chlorosis and leaf malformations with mosaic mottling symptoms were observed in two brinjal varieties (pusa shyamla and pusa purple cluster) in fields of iari, new delhi, india during 2014-2015. electron microscopy, pcr and sequence analysis first time provided evidence of association of candidatus phytoplasma trifolii with potato virus x and potato virus y in brinjal in india. | 2016 | 27366775 |
| automated rflp pattern comparison and similarity coefficient calculation for rapid delineation of new and distinct phytoplasma 16sr subgroup lineages. | phytoplasmas are cell wall-less bacteria that cause numerous diseases in several hundred plant species. during adaptation to transkingdom parasitism in diverse plant and insect hosts, phytoplasma evolution has given rise to widely divergent lineages. since phytoplasmas cannot be cultured in a cell-free medium, measurable phenotypic characters suitable for conventional microbial classification are mostly inaccessible. currently, phytoplasma differentiation and classification are mainly dependent ... | 2008 | 18842858 |
| clover proliferation phytoplasma: 'candidatus phytoplasma trifolii'. | clover proliferation phytoplasma (cpr) is designated as the reference strain for the cp phylogenetic group or subclade, on the basis of molecular analyses of genomic dna, the 16s rrna gene and the 16s-23s spacer region. other strains related to cpr include alfalfa witches'-broom (awb), brinjal little leaf (bll), beet leafhopper-transmitted virescence (bltv), illinois elm yellows (iley), potato witches'-broom (pwb), potato yellows (py), tomato big bud in california (tbbc) and phytoplasmas from fr ... | 2004 | 15280313 |
| molecular characterization, vector identification and sources of phytoplasmas associated with brinjal little leaf disease in india. | 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, r ... | 2017 | 28391472 |
