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 ...

The pathogenic effector PHYL1_JWB interacts with ZjCURT1A to mediate jujube witches' broom-induced photosynthesis impairment of jujube trees. [PDF]

Plant J
SUMMARY Photosynthesis impairment and the accompanying leaf yellowing represent a prominent and physiologically critical symptom of phytoplasma infection. However, the underlying molecular mechanisms remain poorly understood. In this study, we identified the Jujube Witches' Broom pathogenic effector PHYL1JWB, which was previously reported to induce ...

Phytoplasma Effector SJP8 Suppresses Host Immunity by Promoting the Degradation of ZjMYB15 and ZjMYB86-like to Perturb Jasmonic Acid and Hydrogen Peroxide Homeostasis in Jujube. [PDF]

Mol Plant Pathol
SJP8 suppresses plant immunity by perturbing JA and H2O2 homeostasis via the SJP8‐ZjMYB15/ZjMYB86‐like‐ZjJAIPHX1/ZjPOD43 module, leading to dwarfism and chlorosis. ABSTRACT ‘Candidatus Phytoplasma ziziphi’ infection causes severe damage to jujube (Ziziphus jujuba), inducing symptoms such as branch clustering, dwarfism, chlorosis and phyllody, leading ...

Identification of Genes Involved in Resistance to Flavescence Dorée Disease of Grapevine: A Model Study Using Arabidopsis thaliana. [PDF]

Mol Plant Pathol
Arabidopsis 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 ...

Molecular characterization and evolution of the resident population of some alfalfa mosaic virus (AMV) isolates in Egypt

BMC Microbiology, 2023
Background Alfalfa mosaic virus (AMV) is an important virus affecting many vegetable crops in Egypt. In this study, virus isolates were collected from naturally infected potato, tomato, alfalfa and clover plants that showed suspected symptoms of AMV in ...

From sequences to species: Charting the phytoplasma classification and taxonomy in the era of taxogenomics

Frontiers in Microbiology, 2023
Phytoplasma taxonomy has been a topic of discussion for the last two and half decades. Since the Japanese scientists discovered the phytoplasma bodies in 1967, the phytoplasma taxonomy was limited to disease symptomology for a long time.
