Conventional breeding for resistance to whitefly-transmitted geminiviruses
The whitefly Bemisia tabaci Genn. is a pervasive pest and vector of plant viruses. The existence of B. tabaci biotypes and numerous whitefly-transmitted geminiviruses (begomoviruses) affecting food and industrial crops, has become a major constraint to agricultural development in tropical and subtropical regions of the world. The predominant whitefly and begomovirus method of control has been t...
متن کاملNucleotide sequence evidence for the occurrence of three distinct whitefly-transmitted geminiviruses in cassava.
The complete nucleotide sequence of the DNA of Indian cassava mosaic virus (ICMV) and a key part of that of a group B isolate of African cassava mosaic virus from Malawi (ACMV-M) were determined and compared at the nucleotide and encoded amino acid levels with the published sequences of an ACMV group A isolate (ACMV-K) and other whitefly-transmitted gemini-viruses (WTGs). The DNA of ICMV consis...

متن کاملCharacterization of two polyvalent phages infecting Enterobacteriaceae
Bacteriophages display remarkable genetic diversity and host specificity. In this study, we explore phages infecting bacterial strains of the Enterobacteriaceae family because of their ability to infect related but distinct hosts. We isolated and characterized two novel virulent phages, SH6 and SH7, using a strain of Shigella flexneri as host bacterium. Morphological and genomic analyses reveal...
متن کاملTomato dwarf leaf curl virus, a new bipartite geminivirus associated with tomatoes and peppers in Jamaica and mixed infection with tomato yellow leaf curl virus
Genomic characterization using nonradioactive probes, polymerase chain reaction with degenerate primers for whitefly transmitted geminiviruses and nucleotide sequencing were used to describe a new bipartite geminivirus, associated with dwarfing and leaf curling of tomatoes and peppers in Jamaica. Partial DNA-A and DNA-B clones were obtained. DNA sequence analysis showed that tomato and pepper s...
