  • 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.
