| reduced diversity in the bacteriome of the phytophagous mite brevipalpus yothersi (acari: tenuipalpidae). | tenuipalpidae comprises mites that transmit viruses to agriculturally important plants. several tenuipalpid species present parthenogenesis, and in brevipalpus yothersi, the endosymbiont cardinium has been associated with female-only colonies. it is unclear what the bacterial composition of b. yothersi is, and how common cardinium is in those microbiomes. we performed a comparative analysis of the bacteriomes in three populations of b. yothersi and three additional tetranychoidea species using s ... | 2016 | 27999386 |
| phylogenetic and molecular variability studies reveal a new genetic clade of citrus leprosis virus c. | citrus leprosis virus c (cilv-c) causes a severe disease affecting citrus orchards in the western hemisphere. this study reveals the molecular variability of the virus by analyzing four genomic regions (p29, p15, mp and rna2-intergenic region) distributed over its two rnas. nucleotide diversity (π) values were relatively low but statistically different over the analyzed genes and subpopulations, indicating their distinct evolutionary history. values of πp29 and πmp were higher than those of πp15 ... | 2016 | 27275832 |
| diversity and genetic variation among brevipalpus populations from brazil and mexico. | brevipalpus phoenicis s.l. is an economically important vector of the citrus leprosis virus-c (cilv-c), one of the most severe diseases attacking citrus orchards worldwide. effective control strategies for this mite should be designed based on basic information including its population structure, and particularly the factors that influence its dynamics. we sampled sweet orange orchards extensively in eight locations in brazil and 12 in mexico. population genetic structure and genetic variation b ... | 2015 | 26207373 |
| virus-vector relationship in the citrus leprosis pathosystem. | citrus leprosis has been one of the most destructive diseases of citrus in the americas. in the last decade important progress has been achieved such as the complete genome sequencing of its main causal agent, citrus leprosis virus c (cilv-c), belonging to a new genus cilevirus. it is transmitted by brevipalpus yothersi baker (acari: tenuipalpidae), and is characterized by the localized symptoms it induces on the leaves, fruits and stems. it occurs in the american continents from mexico to argen ... | 2017 | 28417249 |
| analysis of genetic variation in brevipalpus yothersi (acari: tenuipalpidae) populations from four species of citrus host plants. | we studied species diversity and genetic variation among populations of brevipalpus mites from four species of citrus host plants. we sampled mites on orange, lime, grapefruit and mandarin trees from orchards at six localities distributed in the five most important citrus producing states in mexico. genetic variation among citrus host plants and localities were assessed by analysis of nucleotide sequence data from fragments of the mitochondrial cytochrome oxidase subunit i (coi). both brevipalpu ... | 2016 | 27736923 |
