Homologous recombination in an algal nuclear genome

摘要

Exemplary transformation methods are provided for introducing deoxyribonucleic acid (DNA) into the nucleus of an algal cell. A transformation construct may be prepared, with the transformation construct having a first sequence of DNA similar to a corresponding first sequence of nuclear DNA, a second sequence of DNA similar to a corresponding second sequence of the nuclear DNA, and a sequence of DNA of interest inserted between the first and second sequences of DNA of the transformation construct. A target sequence of DNA inserted between the first and second corresponding sequences of the nuclear DNA may be transformed, resulting in replacement of the target sequence of DNA with the sequence of DNA of interest. Also provided are exemplary transformation constructs, with some transformation constructs having a first sequence of DNA similar to a corresponding first sequence of nuclear DNA of an algal cell, a second sequence of DNA similar to a corresponding second sequence of nuclear DNA of the algal cell, and a sequence of DNA of interest inserted between the first and second sequences of the transformation construct.
