Cucumber mosaic virus (CMV) comprises numerous isolates with various levels of in-host diversity. Subgroup-distinctive features of the Fny and LS strains provided us with a platform to genetically map the viral control elements for genetic variation in planta. We found that both RNAs 1 and 2 controlled levels of genetic diversity, and further fine mapping revealed that the control elements of m...

tomato is one of the most important vegetables in iran and throughout the world with crop loss caused by several viruses. this survey was carried out to detect the viruses causing mosaic symptoms on tomato in yazd city (iran). a total of 451 samples of tomato leaves showing mosaic symptoms were collected from fields and greenhouses during 2012-2013 growing season. collected samples were analyze...

Cucumber green mottle mosaic virus (CGMMV) is an economically important pathogen and causes significant reduction of both yield and quality of cucumber (Cucumis sativus). Currently, there were no satisfied strategies for controlling the disease. A better understanding of microRNA (miRNA) expression related to the regulation of plant-virus interactions and virus resistance would be of great assi...

Cucumber (Cucumis sativus L.) has a large, paternally transmitted mitochondrial genome. Cucumber plants regenerated from cell cultures occasionally show paternally transmitted mosaic (MSC) phenotypes, characterized by slower growth, chlorotic patterns on the leaves and fruit, lower fertility, and rearrangements in their mitochondrial DNAs (mtDNAs). MSC lines 3, 12, and 16 originated from differ...

bacillus anthracis as a spore-forming bacterium is the causative agent for anthrax. three proteins from b. anthracis including protective antigen (pa), lethal factor (lf) and edema factor (ef) are causative factors of this bacteria. to produce plant-based vaccine, fusion protein of pa 4 domain and lf 1 domain via furin cleavage site joined to subunit b vibrio cholera toxin (ctb) as an inducer o...

The mitochondrial genome of cucumber shows paternal transmission and there are no reports of variation for mitochondrial transmission in cucumber. We used a mitochondrially encoded mosaic (MSC) phenotype to reveal phenotypic variation for mitochondrial-genome transmission in cucumber. At least 10 random plants from each of 71 cucumber plant introductions (PIs) were crossed as the female with an...

Virus diseases greatly affect oilseed rape (Brassica napus) production. Investigating antiviral genes may lead to the development of disease-resistant varieties of oilseed rape. In this study, we examined the effects of the suppressor of gene silencing 3 in Brassica napus (BnSGS3, a putative antiviral gene) with different genus viruses by constructing BnSGS3-overexpressing (BnSGS3-Ov) and BnSGS...
