Phytoplasma Transmission by Seed
, 2019 The transmission of phytoplasmas by seed was reported in several herbaceous and some woody plant species. The seedlings were usually analyzed for the presence of phytoplasmas in different stages of growth by nested-PCR/RFLP analysis and phytoplasmas belonging to different ribosomal groups according with species and geographical distribution were ...

Mapping the Phytoplasma Chromosome
, 2012 Physical and genetic mapping of the phytoplasma chromosome can be a useful tool in a genome sequencing project in order to assemble the in silico-predicted contigs robustly. Mapping consists of four distinct steps: preparation of phytoplasma chromosomes from infected plants, single- and double-digestion of chromosomes with rare-cutting restriction ...

Phytoplasma and phytoplasma diseases: a review of recent research
Phytopathologia Mediterranea, 2009 Numerous yellows-type diseases of plants have been associated with wall-less prokaryote pathogens – phytoplasma over the last 40 years. These pathogens cannot be grown in axenic culture so that advances in their study are mainly achieved by molecular techniques.

Identification of Genes Involved in Resistance to Flavescence Dorée Disease of Grapevine: A Model Study Using Arabidopsis thaliana. [PDF]
Mol Plant PatholArabidopsis thaliana genes conferring resistance to flavescence dorée (FD) phytoplasma were identified, revealing vector‐independent defence mechanisms and providing potential targets for breeding FD‐resistant grapevine. ABSTRACT Flavescence dorée (FD), caused by FD phytoplasma (FDp) and transmitted by the leafhopper Scaphoideus titanus, is a ...
