  • Whisker-mediated transformation of plant cell aggregates and plant tissues and regeneration of plants thereof
    Publication number: 20090013430
    Abstract: Plant cell aggregates and plant tissues can be transformed by elongated, needle-like structures called “whiskers”. The process comprises the agitation of plant cell aggregates and plant tissues of the plant to be transformed in the presence of DNA and whiskers, whereby DNA uptake and integration thereof in facilitated. The process may be applicable to other plant cell aggregates and plant tissues which have not proven easily transformable by other techniques.
    Type: Application
    Filed: December 7, 2007
    Publication date: January 8, 2009
    Inventors: Joseph F. Petolino, Dayakar R. Pareddy, Nicole L. Hopkins, Katherine Armstrong

  • Regulatory sequences useful for gene expression in plant embryo tissue
    Patent number: 6410828
    Abstract: This invention relates to compositions and methods useful in the production of transgenic plants. In particular, the invention relates to maize metallothionein gene transcription regulatory sequences which are useful for directing expression of heterologous DNAs in plant embryo tissue. The invention also relates to expression cassettes containing the promoter sequences and to transgenic plants containing the expression cassettes.
