Abstract
This invention is related to methods and systems for vector assembly for transgenic plants. A uniform modular process is used to reduce cycle time and the methods and systems provided herein can increase cloning throughput using multiple-well plates, for example 96-well plates. In some embodiments, the methods and systems provided herein eliminate or reduce the need for sequencing confirmation because no PCR is involved in the vector assembly process.
Claims8
A method for DNA assembly, comprising,
- (a) providing a first DNA molecule comprising a Kozak sequence, wherein the Kozak sequence is selected from the group consisting of SEQ ID NOs:
- 1-43 and 64-74;
- (b) providing a second DNA molecule comprising the same Kozak sequence of step (a) at one end and a six frame stop sequence at the other end, wherein the six frame stop sequence is selected from the group consisting of SEQ ID NOs:
- 75-80;
- (c) providing a third DNA molecule comprising the same six frame stop sequence of step (b);
- (d) providing a fourth DNA molecule comprising a linear vector sequence;
- and
- (e) assembling a product vector using the DNA molecules of steps (a), (b), (c), and (d) in the presence of at least one recombinase, where the Kozak sequence and the six frame stop sequence provide junction homologies for DNA recombination and wherein the product vector has sequences in the order of the DNA molecules from steps (a), (b), (c), and (d).
