From darkness to light: Genetic manipulation of an atypical plant virus unveils key insights into kitavirus biology, highlighting capsid protein and eIF4A engagement to drive viral infection. [PDF]

PLoS Pathogens
Kitaviridae, a newly recognized virus family, includes plant viruses infecting crops of great global importance, notably citrus. Despite its significant impact on citrus agricultural production, the molecular mechanisms underlying kitavirus infections ...

Susceptibility to cyflumetofen in populations of the citrus leprosis mite, Brevipalpus yothersi, from Brazilian citrus orchards. [PDF]

Pest Manag Sci
Brevipalpus yothersi, the vector of citrus leprosis virus, showed high susceptibility to cyflumetofen. Its low resistance suggests it is effective, but should be rotated with other acaricides with different modes‐of‐action for sustainable management.

Pest categorisation of Diaphorina citri

EFSA Journal, Volume 19, Issue 1, January 2021., 2021
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Diaphorina citri (Hemiptera: Liviidae) (Asian citrus psyllid) for the EU. D. citri is a key pest of citrus in several countries as it is a vector of serious bacterial pathogens, the putative causal agents of Huanglongbing (HLB) also known as citrus greening.

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad-Spectrum Antiviral Resistance in Crops. [PDF]

Plant Biotechnol J
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...
