摘要:
Compositions and methods are provided for the introduction and the regulated expression of genes in plants. Compositions include promoter constructs that provide a level of activity useful for the regulated expression of site-specific recombinases, while avoiding premature excision. Further provided are isolated polynucleotides encoding novel babyboom polypeptides, expression cassettes, and plants comprising the same. Methods for the introduction of genes into plants are provided, including methods for plastid transformation and methods for the transformation of tissues from mature seeds and leaves.
摘要:
A variety of methods and compostions are provided, including methods and compositions for targeted modification of a specific target site in a cell or organism, methods for integrating polynucleotides of interest, methods to assess promoter activity, directly select transformed organisms, minimize or eliminate expression resulting from random integration into the genome of an organism, such as a plant, remove polynucleotides of interest, combine multiple transfer cassettes, invert or excise a polynucleotide, silence a gene, and identify and/or characterize transcriptional regulating regions. The methods involve the introduction of a cell proliferation factor and a double-strand break-inducing enzyme into an organism.
