Carica papaya MicroRNAs Are Responsive to Papaya meleira virus Infection
MicroRNAs are implicated in the response to biotic stresses. Papaya meleira virus (PMeV) is the causal agent of sticky disease, a commercially important pathology in papaya for which there are currently no resistant varieties. PMeV has a number of unusual features, such as residence in the laticifers of infected plants, and the response of the papaya to PMeV infection is not well understood. Th...
متن کاملOxidative Stress Defence Response of Carica papaya Challenged by Nitric Oxide, Papaya meleira virus and Saccharomyces cerevisiae
Seedlings of papaya (Carica papaya), cultivar Golden, were exposed to a nitric oxide donor, sodium nitroprusside (SNP), Papaya meleira virus (PMeV) and yeast (Saccharomyces cerevisiae, as a model fungal elicitor). The aim was to investigate the response of C. papaya to infection and the role of nitric oxide in this process. SNP alone led to a short lived (6 h) burst of peroxidase activity and a...
متن کاملThe dsRNA Virus Papaya Meleira Virus and an ssRNA Virus Are Associated with Papaya Sticky Disease
Papaya sticky disease, or "meleira", is one of the major diseases of papaya in Brazil and Mexico, capable of causing complete crop loss. The causal agent of sticky disease was identified as an isometric virus with a double stranded RNA (dsRNA) genome, named papaya meleira virus (PMeV). In the present study, PMeV dsRNA and a second RNA band of approximately 4.5 kb, both isolated from latex of pa...
متن کاملPhysical Characteristics of the Leaves and Latex of Papaya Plants Infected with the Papaya meleira Virus.
Sticky disease, which is caused by Papaya meleira virus (PMeV), is a significant papaya disease in Brazil and Mexico, where it has caused severe economic losses, and it seems to have spread to Central and South America. Studies assessing the pathogen-host interaction at the nano-histological level are needed to better understand the mechanisms that underlie natural resistance. In this study, th...
متن کاملErwinia papayae sp. nov., a pathogen of papaya (Carica papaya).
Bacterial canker of papaya (Carica papaya) emerged during the 1980s in different islands of the Caribbean. Nineteen strains of Gram-negative, rod-shaped, non-spore-forming bacteria isolated from papaya were compared to 38 reference and type strains of phytopathogenic Enterobacteriaceae and related bacteria. Phylogenetic analysis of 16S rRNA gene sequences showed that the papaya strains belonged...
