High impact information on Phytoplasma

  • The infection by phytoplasma in C. roseus leaves causes an increase of metabolites related to the biosynthetic pathways of phenylpropanoids or terpenoid indole alkaloids: chlorogenic acid, loganic acid, secologanin, and vindoline [1].
  • In situ RNA hybridization analyses revealed that TAG1 transcripts were restricted to the same floral meristem territories in healthy and infected tomatoes, indicating that tissue-specific expression of TAG1 was not affected by the stolbur phytoplasma infection [2].
  • The first group comprises genes that are up-regulated by phytoplasma presence: in particular, a gene encoding the heat-shock protein HSP-70, a gene encoding a metallothionein (MT) and another homologous to the EST 673 cDNA clone of P. armeniaca, whose function was unknown [3].
  • Genes coding for elongation factors G (fus) and Tu (tuf) of the non-culturable apple proliferation (AP) phytoplasma were cloned and sequenced [4].
  • This study suggests that the Sec system operates in this phytoplasma to export OY Amp [5].

Chemical compound and disease context of Phytoplasma


Biological context of Phytoplasma


Gene context of Phytoplasma

  • Phylogenetic analysis of representative genes showed that the TBB phytoplasma grouped with the mycoplasmas with the exception of the TBB phytoplasma secA gene, which grouped with the onion yellows phytoplasma [12].
  • Relative quantification of chrysanthemum yellows (16Sr I) phytoplasma in its plant and insect host using real-time polymerase chain reaction [13].
  • We report the sequence and catalytic properties of RNase P RNA from the phytoplasma causing apple proliferation disease [14].
  • Two most important diseases associated with parthenium were a rust disease, caused by Puccinia abrupta var. partheniicola, and a phyllody disease, caused by a phytoplasma of fababean phyllody (PBP) phytoplasma group [15].
