    • Compositions and methods are provided for novel Cas9 systems, including, but not limiting to, novel guide polynucleotide/Cas9 endonucleases complexes, single or dual guide RNAs, guide RNA elements, and Cas9 endonucleases. The novel Cas9 systems described herein are derived from a CRISPR-Cas locus that differs from type II CRISPR-Cas loci, in that the novel CRISPR-Cas locus described herein contains multiple CRISPR arrays flanking a tracrRNA encoding region and cas9 gene and does not contain a cas1 gene and a cas2 gene. The present disclosure also describes methods for genome modification of a target sequence in the genome of a cell, for gene editing, and for inserting a polynucleotide of interest into the genome of a cell.
    • 为新的Cas9系统提供了组合物和方法,包括但不限于新的指导性多核苷酸/ Cas9内切核酸酶复合物,单或双引导RNA,引导RNA元件和Cas9内切核酸酶。 本文描述的新型Cas9系统来源于不同于II型CRISPR-Cas基因座的CRISPR-Cas基因座,因为本文所述的新型CRISPR-Cas基因座包含侧接tracrRNA编码区和cas9基因且不含有多个CRISPR阵列 cas1基因和cas2基因。 本公开还描述了用于基因组修饰细胞基因组中的靶序列,用于基因编辑以及用于将目的多核苷酸插入细胞基因组中的方法。

    • Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell, for genome editing of a nucleotide sequence in the genome of a plant or plant cell, and/or for inserting or deleting a polynucleotide of interest into or from the genome of a plant. The methods and compositions employ a guide polynucleotide/ Cpf1 endonuclease system to provide an effective system for modifying or altering target sequences within the genome of a plant, plant cell or seed. Also provided are guide polynucleotides/Cpf1 endonucleases complexes, guide polynucleotides, plant-optimized Cpf1 endonuclease sequences, recombinant DNA constructs comprising plant-optimized Cpf1 endonucleases genes, and combinations thereof.
    • 提供组合物和方法用于基因组修饰植物或植物细胞基因组中的靶序列,用于基因组编辑植物或植物细胞基因组中的核苷酸序列,和/或 用于将目的多核苷酸插入或从植物基因组中缺失。 该方法和组合物使用引导多核苷酸/ Cpf1内切核酸酶系统来提供用于修饰或改变植物,植物细胞或种子的基因组内的靶序列的有效系统。 还提供了指导性多核苷酸/ Cpf1内切核酸酶复合物,指导性多核苷酸,植物优化的Cpf1核酸内切酶序列,包含植物优化的Cpf1内切核酸酶基因的重组DNA构建体,以及它们的组合。
