Characterization of a Virus Infecting Citrus volkameriana with Citrus Leprosis-Like Symptoms [PDF]

Phytopathology®, 2012
A Citrus volkameriana tree displaying symptoms similar to citrus leprosis on its leaves and bark was found in Hawaii. Citrus leprosis virus C (CiLV-C)-specific detection assays, however, were negative for all tissues tested. Short, bacilliform virus-like particles were observed by transmission electron microscopy in the cytoplasm of symptomatic leaves

Bacterial plant pathogens affect the locomotor behavior of the insect vector: a case study of Citrus volkameriana–Triozae erytreae–Candidatus Liberibacter asiaticus system [PDF]

Insect Science, 2023
AbstractPlant pathogens can alter the behavior of their insect vectors as well as their survival and reproduction. The African psyllid, Trioza erytreae, is one of the vectors of Huanglongbing, a citrus disease caused mainly by “Candidatus Liberibacter asiaticus” (CLas). The purpose of this study was to characterize the effects of CLas on the psyllid, T.

Photosystem 2 activity of Citrus volkameriana (L.) leaves as affected by Mn nutrition and irradiance

Photosynthetica, 2007
Citrus volkameriana (L.) plants were grown for 43 d in nutrient solutions containing 0, 2, 14, 98, or 686 µM Mn (Mn0, Mn2, Mn14, Mn98, and Mn686, respectively). To adequately investigate the combined effects of Mn nutrition and irradiance on photosystem 2 (PS2) activity, irradiance response curves for electron transport rate (ETR), nonphotochemical ...
