Isolation and characterization of three bacteriophages infecting Erwinia amylovora and their potential as biological control agent

Egyptian Journal of Biological Pest Control, 2023
Background Fire Blight, incited by Erwinia amylovora, is one of the most damaging pear and apple diseases in the world. Fire blight was introduced to Egypt in the 1960 and threatens the Egypt’s costs for pear industry.

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.

Effect of the entomopathogenic fungus, Beauveria bassiana inhibiting whitefly transmission of squash leaf curl virus infecting squash

Egyptian Journal of Biological Pest Control, 2023
Background Squash leaf curl virus (SLCV) is efficiently transmitted and spread by the whitefly, Bemisia tabaci (Gennadius), which is the only vector that transmits begomoviruses naturally causing huge crop losses through feeding damage.

Iodixanol density gradients as an effective phytoplasma enrichment approach to improve genome sequencing

Frontiers in Microbiology, 2022
Obtaining complete phytoplasma genomes is difficult due to the lack of a culture system for these bacteria. To improve genome assembly, a non-ionic, low- and iso-osmotic iodixanol (Optiprep™) density gradient centrifugation method was developed to enrich

Phytoplasma: Phytopathogenic Mollicutes [PDF]

Annual Review of Microbiology, 2000
▪ Abstract  During the past decade, research has yielded new knowledge about the plant and insect host ranges, geographical distribution, and phylogenetic relationships of phytoplasmas, and a taxonomic system has emerged in which distinct phytoplasmas are named as separate “Candidatus phytoplasma species.” In large part, this progress has resulted ...

Detection, Identification and Molecular Characterization of the 16SrII-V Subgroup Phytoplasma Strain Associated with Pisum sativum and Parthenium hysterophorus L.

Plants, 2023
Two unrelated plant species, green pea and parthenium weed, harboring typical phytoplasma symptoms, were discovered in Yunlin, Taiwan. Green pea (Pisum sativum.) and parthenium weed (Parthenium hysterophorus L.) are both herbaceous annual plants ...
