The field of synthetic biology promises to revolutionize biotechnology through the design of organisms with novel phenotypes useful for medicine, agriculture and industry. However, a limiting factor is the ability of current methods to assemble complex DNA molecules encoding multiple genetic elements in various predefined arrangements. We present here a(More)
We have developed a protocol to assemble in one step and one tube at least nine separate DNA fragments together into an acceptor vector, with 90% of recombinant clones obtained containing the desired construct. This protocol is based on the use of type IIs restriction enzymes and is performed by simply subjecting a mix of 10 undigested input plasmids (nine(More)
Generation of customized DNA binding domains targeting unique sequences in complex genomes is crucial for many biotechnological applications. The recently described DNA binding domain of the transcription activator-like effectors (TALEs) from Xanthomonas consists of a series of repeats arranged in tandem, each repeat binding a nucleotide of the target(More)
A two-component hybrid seed system has been developed that is broadly applicable and provides for effective generation and maintenance of the male-sterile parent, hybrid seed production and full restoration of fertility in the hybrid seed. The technology is based on the functional interaction of two loci that are inserted in the same position on two(More)
Plant Synthetic Biology requires robust and efficient methods for assembling multigene constructs. Golden Gate cloning provides a precision module-based cloning technique for facile assembly of multiple genes in one construct. We present here a versatile resource for plant biologists comprising a set of cloning vectors and 96 standardized parts to enable(More)
A library of synthetic promoters containing the binding site of a single designer transcription activator-like effector (dTALE) was constructed. The promoters contain a constant sequence, consisting of an 18-base long dTALE-binding site and a TATA box, flanked by degenerate sequences of 49 bases downstream and 19 bases upstream. Forty-three of these(More)
