TAL effectors and the executor R genes
Transcription activator-like (TAL) effectors are bacterial type III secretion proteins that function as transcription factors in plants during Xanthomonas/plant interactions, conditioning either host susceptibility and/or host resistance. Three types of TAL effector associated resistance (R) genes have been characterized-recessive, dominant non-transcriptional, and dominant TAL effector-depende...
متن کاملTAL effectors: finding plant genes for disease and defense.
Transcription activator like effectors (TALEs) are injected via the type III secretion pathway of many plant pathogenic Xanthomonas spp. into plant cells where they contribute to disease or trigger resistance by binding to DNA and turning on TALE-specific host genes. Advances in our understanding of TALEs and their targets have yielded new models for pathogen recognition and defense. Similarly,...
متن کاملTAL effectors: function, structure, engineering and applications.
TAL effectors are proteins secreted by bacterial pathogens into plant cells, where they enter the nucleus and activate expression of individual genes. TAL effectors display a modular architecture that includes a central DNA-binding region comprising a tandem array of nearly identical repeats that are almost all 34 residues long. Residue number 13 in each TAL repeat (one of two consecutive polym...
متن کاملTAL effectors: tools for DNA Targeting
Xanthomonas phytopathogenic bacteria produce unique transcription activator-like effector (TALE) proteins that recognize and activate specific plant promoters through a set of tandem repeats. A unique TALE-DNA-binding code uses two polymorphic amino acids in each repeat to mediate recognition of specific nucleotides. The order of repeats determines effector's specificity toward the cognate nucl...
متن کاملTAL Effectors Specificity Stems from Negative Discrimination
Transcription Activator-Like (TAL) effectors are DNA-binding proteins secreted by phytopathogenic bacteria that interfere with native cellular functions by binding to plant DNA promoters. The key element of their architecture is a domain of tandem-repeats with almost identical sequences. Most of the polymorphism is located at two consecutive amino acids termed Repeat Variable Diresidue (RVD). T...
