The Agrobacterium rhizogenes GALLS gene encodes two secreted proteins required for genetic transformation of plants.
Agrobacterium tumefaciens and Agrobacterium rhizogenes are related pathogens that cause crown gall and hairy root diseases, which result from integration and expression of bacterial genes in the plant genome. Single-stranded DNA (T strands) and virulence proteins are translocated into plant cells by a type IV secretion system. VirD2 nicks a specific DNA sequence, attaches to the 5' end, and pil...
متن کاملNatural genetic transformation: prevalence, mechanisms and function.
Studies show that gene acquisition through natural transformation has contributed significantly to the adaptation and ecological diversification of several bacterial species. Relatively little is still known, however, about the prevalence and phylogenetic distribution of organisms possessing this property. Thus, whether natural transformation only benefits a limited number of species or has a l...
متن کاملAgrobacterium rhizogenes-Mediated Transformation of the Parasitic Plant Phtheirospermum japonicum
BACKGROUND Plants within the Orobanchaceae are an agriculturally important group of parasites that attack economically important crops to obtain water and nutrients from their hosts. Despite their agricultural importance, molecular mechanisms of the parasitism are poorly understood. METHODOLOGY/PRINCIPAL FINDINGS We developed transient and stable transformation systems for Phtheirospermum jap...
متن کاملNatural genetic transformation of Streptococcus mutans growing in biofilms.
Streptococcus mutans is a bacterium that has evolved to be dependent upon a biofilm "lifestyle" for survival and persistence in its natural ecosystem, dental plaque. We initiated this study to identify the genes involved in the development of genetic competence in S. mutans and to assay the natural genetic transformability of biofilm-grown cells. Using genomic analyses, we identified a quorum-s...
متن کاملTransformation of Natural Genetic Variation into Haemophilus Influenzae Genomes
Many bacteria are able to efficiently bind and take up double-stranded DNA fragments, and the resulting natural transformation shapes bacterial genomes, transmits antibiotic resistance, and allows escape from immune surveillance. The genomes of many competent pathogens show evidence of extensive historical recombination between lineages, but the actual recombination events have not been well ch...
