Department of Plant Science The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date Jul- 27. 1Q7Q ABSTRACT Cherry leaf roll virus, as a nepovirus with a bipartite genome, can be genetically analysed by comparing the properties of distinct 'parental' strains and the pseudorecombinant isolates generated from them. In the present work, the elderberry (E) and rhubarb (R) strains were each purified and separated into their middle (M) and bottom (B) components by sucrose gradient centrifugation followed by near- equilibrium banding in cesium chloride. RNA was extracted from the the separated components by treatment with a dissociation buffer followed by sucrose gradient centrifugation. Extracted M-RNA of E-strain and B-RNA of R-strain were mixed and inoculated to a series of test plants as were M-RNA of R-strain and B-RNA of E-strain. -

Virus Integration and Tandem Repeats in the Genomes of Petunia a Thesis
Virus integration and tandem repeats in the genomes of Petunia A thesis submitted to the University of Leicester for the degree of Doctor of Philosophy By Osamah Nadhim Kadhim Alisawi M.Sc. January 2019 Department of Genetics and Genome Biology i Abstract The integration of endogenous pararetroviruses (EPRVs) and tandemly repeated sequences were examined in whole genome raw reads, and two genome assemblies, in diploid Petunia species including hybrid-derivatives and their ancestors, using bioinformatics, molecular biology, cytogenetics and microscopy. Three types of EPRV clusters (petuvirus-, florendovirus- and caulimovirus-like sequences) were found. Chromosomal signals of PVCV (Petunia vein clearing virus) were seen by in situ hybridization in all Petunia species. Fragmented parts of four novel florendovirus-like sequences were found and the complete sequence was reconstructed, adding petunia to the 27 known host species. Chromosome III of P. axillaris and P. hybrida Rdc showed strong pericentromeric signal of PVCV and Florendovirus suggesting both EPRVs have similar positions, integration patterns and endogenization events (unlike P. integrifolia subsp inflata and P. axillaris subsp parodii). The caulimovirus-like sequence cluster was less abundant in genomes, with four novel members. RNA analysis from infected and healthy petunia samples revealed expression of endogenous PVCV and Caulimovirus sequences, unlike Florendovirus (not detected in RNA). The episomal form of vertically transmitted PVCV was integrated near the telomere of heterologous chromosomes. Transmission electron microscopy (TEM) showed differences in number and size of PVCV particles and inclusion bodies for both chlorotic spots and vein clearing symptoms, the latter correlated with PVCV particles in cytoplasm from vascular bundle cells. -

OF THEOBROMA CACAO: ECOLOGY AND POTENTIAL FOR BIOLOGICAL CONTROL OF CACAO DISEASES A Dissertation in Plant Pathology by Rachel L. Melnick 2010 Rachel L. Melnick Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy May 2010 The dissertation of Rachel L. Melnick was reviewed and approved* by the following: Paul A.

Bailey Adjunct Professor of Plant Pathology Plant Pathologist at USDA-ARS SPCL Special Member Maria del Mar Jimenez-Gasco Assistant Professor of Plant Pathology Gary W. Moorman Professor of Plant Pathology Roger T. Koide Professor of Horticultural Ecology Frederick E. Gildow Professor of Plant Pathology Head of the Department of Plant Pathology *Signatures are on file in the Graduate School iii ABSTRACT Yield of Theobroma cacao, the chocolate tree, is drastically limited by disease. In South America, there are three key diseases: black pod, caused by Phytophthora spp.; frosty pod, caused by Moniliophthora roreri; and witches‟ broom, caused by Moniliophthora perniciosa. Although chemical control options exist, farmers typically only use cultural disease management such as phytosanitary pruning. Agrochemical use can be problematic in the developing countries where cacao is grown due to large risks to human health and the environment. There has been increased interest in the use of biological control for management of cacao diseases due to problems associated with pesticide use as well as consumer desire for organic chocolate. Fungal species have been the main focus for research on biological control of cacao diseases, while cacao- associated bacteria have been nearly ignored. -

The beans were iDoc:ula&ed via viruliferous nymphs ofmealy bugs, and observed after planting for 3 months. Patches of barks of severe symptom bearing cocoa types were also tested through grafting on healthy Amelonado plants and observed for 3 months. Significant differences were observed in the cocoa types in terms of symptoms appearance and in severity.
