    Heritable DNA-free genome editing of canola (Brassica napus L.) using PEG-mediated transfection of isolated protoplasts

    Application of new genome editing technologies for plant improvement depends on efficient delivery of editing components into plant cells. For editing of canola, which is an important oil crop, CRISPR/Cas9 and Ag...

    Demonstration of targeted crossovers in hybrid maize using CRISPR technology

    Naturally occurring chromosomal crossovers (CO) during meiosis are a key driver of genetic diversity. The ability to target CO at specific allelic loci in hybrid plants would provide an advantage to the plant ...

    Transient Expression and Stable Transformation of Maize Using Microprojectiles

    High-velocity microprojectiles provide a direct means of introducing DNA into plant cells (Klein et al., 1987, 1988a, 1988b; Wang et al., 1988). In principle, this method could be used to introduce DNA into any a...

    Inheritance and Expression of Chimeric Genes in the Progeny of Transgenic Maize Plants

    We obtained transgenic maize plants by using high-velocity microprojectiles to transfer genes into embryogenic cells. Two selectable genes were used to confer resistance to either chlorsulfuron or phosphinothr...
