Possible Internalization of an Enterovirus in Hydroponically Grown Lettuce
Several studies have shown that enteric viruses can be transferred onto the surface of vegetables and fruits through spray irrigation, but, recently, reports have suggested viral contamination of vegetables sub-irrigated with reused wastewater. Hydroponic cultures, used to grow ready to eat fresh lettuce, have also been used to study the possibility of viral absorption through roots. This study...
متن کاملManagement of Phytophthora Root and Runner Rot in Cranberry
Phytophthora is a genus of plant pathogens, many species of which live in water or soil. The name means “plant destroyer” in Greek. Phytophthora species are common pathogens in agricultural systems, especially in those where the crop is irrigated with surface or recycled water. In cranberry culture, the most troublesome species is P. cinnamomi, the cinnamon fungus. This pathogen causes a very c...
متن کاملRoot Rot of Pea Caused by Aphanomyces euteiches
Aphanomyces root rot, caused by the oomycete Aphanomyces euteiches, is the most important and destructive disease of pea. Since the inoculum is persistent in the soil, and no resistant cultivars or means of chemical control are available, the disease is difficult to manage. The occurrence of soil suppressiveness against the disease was previously reported, and the main aim of this study was to ...
متن کاملInternalization and dissemination of human norovirus and animal caliciviruses in hydroponically grown romaine lettuce.
Fresh produce is a major vehicle for the transmission of human norovirus (NoV) because it is easily contaminated during both pre- and postharvest stages. However, the ecology of human NoV in fresh produce is poorly understood. In this study, we determined whether human NoV and its surrogates can be internalized via roots and disseminated to edible portions of the plant. The roots of romaine let...
