    • Disclosed are methods for transformation of an androgenic-derived, haploid cell line with a site-specific nuclease. In some embodiments, the androgenic-derived, haploid cell line is a maize microspore-derived plant tissue culture. In addition, the disclosure provides a method for modifying, e.g., by mutating or targeting and integrating donor DNA into, a specific locus of a haploid or dihaploid tissue genome. The disclosure further provides methods for regenerating a whole plant from the haploid or dihaploid tissue that contains either the mutation at a specific genomic locus or a donor DNA integrated within a specific genomic locus may be obtained from the subject disclosure.

    • A method for deleting a region of DNA in a plant. In some embodiments, the method comprises transforming a plant with a nucleic acid molecule, wherein the nucleic acid molecule encodes one or more zinc finger nuclease(s) (ZFNs) operably linked to one or more tissue specific promoter(s), e.g ., a pollen specific promoter. Methods include excising native genes in a plant. Accordingly, in some embodiments, ZFNs are engineered that recognize sequences that flank native plant genes. In further embodiments, ZFNs are expressed under the control of developmental stage specific promoters, such that, for example, nucleic acid sequences are specifically excised in plants during relatively late stages of development. Nucleic acid molecules useful for carrying out disclosed methods and plants produced by the methods are included.
    • ”用于删除植物中的DNA区域的方法。 在一些实施方案中,所述方法包括用核酸分子转化植物,其中所述核酸分子编码与一种或多种组织特异性启动子可操作连接的一种或多种锌指核酸酶(ZFN) 例如花粉特异性启动子。 方法包括切除植物中的天然基因。 因此,在一些实施方案中,工程化ZFN以识别侧接天然植物基因的序列。 在进一步的实施方案中,ZFN在发育阶段特异性启动子的控制下表达,使得例如在发育的相对晚期阶段在植物中特异性切除核酸序列。 包括可用于实施所公开的方法和由该方法产生的植物的核酸分子。
