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.

Genetic analysis of ‘Candidatus Phytoplasma aurantifolia’ associated with witches’ broom on acid lime trees [PDF]

PeerJ, 2018
“Candidatus Phytoplasma aurantifolia” is associated with witches’ broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches’ broom symptoms in some

Phytoplasma-Triggered Ca2+ Influx Is Involved in Sieve-Tube Blockage

Molecular Plant-Microbe Interactions, 2013
Phytoplasmas are obligate, phloem-restricted phytopathogens that are disseminated by phloem-sap-sucking insects. Phytoplasma infection severely impairs assimilate translocation in host plants and might be responsible for massive changes in phloem ...
