This invention relates to recombinant nucleic constructs comprising a DNA binding domain, an endonuclease and a reverse transcriptase and methods of use thereof for modifying nucleic acids in plants.

Compositions and methods for RNA-templated editing in plants

This invention relates to recombinant nucleic constructs comprising a sequence-specific DNA binding protein, DNA-dependent DNA polymerase and a DNA encoded repair template, optionally a DNA endonuclease or wherein the sequence-specific DNA binding protein comprises DNA endonuclease activity, and methods of use thereof for modifying nucleic acids in cells and organisms.

Recruitment of DNA polymerase for templated editing

The present invention relates to the targeted regulation of gene expression and more specifically to synthetic transcription factors (STFs) comprising at least one highly target specific engineered recognition domain and further comprising at least one activation or silencing domain to modulate the expression of a gene of interest, preferably to modulate the transcription of a morphogenic gene of a eukaryote. Further disclosed are methods using the STFs to enhance transformation frequencies, to optimize successful genome editing approaches, to provide haploid or double haploid organisms, and/or to provide compositions suitable for general transformation, but also for breeding purposes.

Targeted transcriptional regulation using synthetic transcription factors

The present invention relates to optimized systems for the genome editing of eukaryotic cells, preferably plant cells. Also provided is a plant delivery system comprising at least one Cpf1 enzyme, or a plant optimized construct encoding the same, to be synergistically combined with a Cpf1 guide RNA system. Further provided is a Cpf1 guide RNA system being flanked by a Hammerhead ribozyme sequence at the 5' end and by a plant-derived Hepatitis Delta Vims (HDV)-like ribozyme sequence at the 3′ end, or being embedded within a coding or non-coding region, of a sequence encoding a frame sequence. Novel plant-derived HDV-like ribozyme sequences are also provided. Further provided are methods for improved genome editing, and the use of the various systems provided herein to obtain transformed plants, plant cells, tissues, organs, or a progeny thereof, or a plant material, modified in a targeted way even at difficult to access target sites.

Optimized plant CRISPR/CPF1 systems

The present invention relates to hybrid nucleic acid sequence constructs comprising a CRISPR nucleic acid sequence and a DNA repair template associated with each other in a covalent and/or non-covalent way for CRISPR based genome engineering. Further provided is a molecular complex additionally comprising at least one CRISPR polypeptide. All components within the complex are in physical proximity. In addition, there is provided a plant, plant cell, a plant material, or a derivative, or progeny thereof comprising the hybrid RNA/DNA sequence and/or the molecular complex. Further, there is provided a method for modifying at least one DNA target sequence in a prokaryotic or eukaryotic cell as well as a method for manufacturing a plant or plant cell. Finally, there is provided the use of at least one hybrid RNA/DNA sequence, or use of a molecular complex for gene editing or genome engineering in a prokaryotic or eukaryotic cell or organism.

Hybrid nucleic acid sequences for genome engineering

Described herein are methods of modifying or editing a target nucleic acid such as methods that edit adenine to cytosine, thymine, or guanine. Compositions and systems for modifying or editing a target nucleic acid are also described. Methods, compositions and systems described herein may be used for generating allelic diversity.

Compositions, systems, and methods for base diversification

Described herein are recruitment methods and compounds, compositions, and systems for recruitment. Also described herein are methods and compositions for template editing of genomic DNA using-derived T-DNA molecules and/or proteins.

Recruitment methods and compounds, compositions and systems for recruitment

This invention relates to recombinant nucleic constructs comprising Type V CRISPR-Cas effector proteins, reverse transcriptases and extended guide nucleic acids and methods of use thereof for modifying nucleic acids in plants.

Compositions and methods for RNA-encoded DNA-replacement of alleles

This invention relates to CRISPR-Cas nucleases codon optimized for expression in plants and nucleic acid constructs encoding base editors comprising a CRISPR-Cas nuclease and a deaminase domain, wherein the nucleic acid constructs are optimized for expression in a plant. The invention further relates to methods of modifying nucleic acids using the nucleic acid constructs.
