Huanglongbing, or citrus greening disease, is an economically devastating bacterial disease of citrus. It associated with infection by the gram-negative bacterium Candidatus Liberibacter asiaticus (CLas). CLas transmitted Diaphorina citri, Asian psyllid (ACP). For insect transmission to occur, must be ingested during feeding on infected phloem sap and cross gut barrier gain entry into vector. To investigate effects exposure at gut-pathogen interface, we performed RNAseq mass...
Abstract Candidatus Liberibacter asiaticus (CLas) is a phloem-limited, gram-negative, fastidious bacterium that associated with the development of citrus greening disease, also known as Huanglongbing (HLB). CLas transmitted by Asian psyllid (ACP) Diaphorina citri , in circulative manner. Two major barriers to transmission within insect are midgut and salivary glands. We performed thorough microscopic analysis following exposure CLas-infected trees. observed changes nuclear architecture,...
"Candidatus Liberibacter asiaticus" is the causative bacterium associated with citrus greening disease. "Ca transmitted by Diaphorina citri more efficiently when it acquired nymphs rather than adults. Why this occurs not known. We compared midguts of D. insects reared on healthy or asiaticus"-infected trees using quantitative PCR, confocal microscopy, and mitochondrial superoxide staining for evidence oxidative stress. Consistent its classification as propagative, titers were higher in...
Transmission of plant viruses by aphids involves multitrophic interactions among host plants, aphid vectors, and viruses. Here, we used small RNA (sRNA) sequencing to visualize the sRNA response Myzus persicae two that M. transmits in different modes: nonpersistent Potato virus Y (PVY) versus persistent leafroll (PLRV). Aphids exposed PLRV produced significantly less 22 mers aligned genome, an abundance 26 27 mers, many which were predicted be piRNA. Additionally, expression Buchnera...
