Phytoplasma Transmission by Seed
2019The 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 ...

Candidatus Phytoplasma asteris (yellow disease phytoplasmas).
2021Abstract Aster yellows (AY) group phytoplasmas affect plants by causing a general reduction in quantity and quality of yield. The most severely affected hosts are carrot, lettuce, onion, spinach and several ornamental crops, including aster, gladiolus, hydrangea, chrysanthemum and purple coneflower.

Phytoplasma diseases of sugarcane
Sugar Tech, 2002Sugarcane is severely affected by yellows and decline diseases of phytoplasmal etiology. These diseases which are of considerable economic importance, cause similar symptoms but differ in the identity of the associated phytoplasmas, vectorship and geographic distribution.

Q-Bank Phytoplasma: A DNA Barcoding Tool for Phytoplasma Identification
2015DNA barcoding is an identification method based on comparison of a short DNA sequence with known sequences from a database. A DNA barcoding tool has been developed for phytoplasma identification. This phytoplasma DNA barcoding protocol based on the tuf gene has been shown to identify phytoplasmas belonging to the following groups: 16SrI, 16SrII ...

Dodder Transmission of Phytoplasmas
2012Transmission of phytoplasmas from naturally infected plant host species using the parasitic plant Cuscuta spp. (dodder) to Catharanthus roseus (Madagascar periwinkle) is an effective way to maintain a wide range of phytoplasmas for further research.

Phytoplasma Plasmid DNA Extraction
2012Phytoplasma plasmids have generally been detected from DNA extracted from plants and insects using methods designed for the purification of total phytoplasma DNA. Methods include extraction from tissues that are high in phytoplasma titre, such as the phloem of plants, with the use of CsCl-bisbenzimide gradients that exploit the low G+C content of ...
