Ralstonia solanacearum is a devastating bacterial phytopathogen with a broad host range. Ralstonia solanacearum injected effector proteins (Rips) are key to the successful invasion of host plants. We have characterized Brg11(hrpB-regulated 11), the first identified member of a class of Rips with high sequence similarity to the transcription activator-like(More)
Whether rice, yeast or fly there is barely a model organism not yet reached by transcription activator-like effectors (TALEs) and their derivative fusion proteins. Insights into fundamental biology are now arriving on the back of work in recent years to develop these proteins as tools for molecular biology. This began with the publication of the simple(More)
The tandem repeats of transcription activator like effectors (TALEs) mediate sequence-specific DNA binding using a simple code. Naturally, TALEs are injected by Xanthomonas bacteria into plant cells to manipulate the host transcriptome. In the laboratory TALE DNA binding domains are reprogrammed and used to target a fused functional domain to a genomic(More)
Transcription Activator-Like Effectors (TALEs) of Xanthomonas bacteria are programmable DNA binding proteins with unprecedented target specificity. Comparative studies into TALE repeat structure and function are hindered by the limited sequence variation among TALE repeats. More sequence-diverse TALE-like proteins are known from Ralstonia solanacearum(More)
Ralstonia solanacearum, a species complex of bacterial plant pathogens divided into four monophyletic phylotypes, causes plant diseases in tropical climates around the world. Some strains exhibit a broad host range on solanaceous hosts, while others are highly host-specific as for example some banana-pathogenic strains. Previous studies showed that(More)
A protein-DNA interface can be engineered in ways that an RNA-DNA interface cannot. Programmable TAL effector derived proteins bind DNA with a series of repeats. Each repeat binds a single DNA base. Repeats can be treated as modules, with a pair of residues in the center defining the target base. A set of 31-33 residues flanking the base specifying residues(More)
