The disclosure pertains to methods and compositions for the rapid and efficient transformation of plants. The disclosure further provides methods for producing a transgenic plant, comprising (a) transforming a cell of an explant with an expression construct comprising (i) a nucleotide sequence encoding a WUS/WOX homeobox polypeptide; (ii) a nucleotide sequence encoding a polypeptide comprising two AP2-DNA binding domains; or (iii) a combination of (i) and (ii); and (b) allowing expression of the polypeptide of (a) in each transformed cell to form a regenerable plant structure in the absence of exogenous cytokinin, wherein no callus is formed; and (c) germinating the regenerable plant structure to form the transgenic plant. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
本公开涉及快速高效转化植物的方法和组合物。本公开进一步提供了生产转基因植物的方法,包括(a)用表达构建体转化外植体细胞,该表达构建体包含(i)编码 WUS/WOX 同源体多肽的核苷酸序列;(ii)编码包含两个 AP2-DNA 结合域的多肽的核苷酸序列;或(iii)(i)和(ii)的组合;和(b)使(a)的多肽在每个转化细胞中表达,以在没有外源细胞分裂素的情况下形成可再生的植物结构,其中不形成胼胝体;和(c)使可再生的植物结构发芽以形成转基因植物。本摘要旨在作为一种扫描工具,用于在特定技术领域进行搜索,并非对本公开内容的限制。
