    摘要: Improved compositions and methods for transformation and regeneration of plants from embryogenic callus are disclosed that include, for example: use of an intermediate-incubation medium after callus induction to increase the competence of the transformed cells for regeneration; dim light conditions during early phases of selection; use of green callus tissue as a target for microprojectile bombardment; and media with optimized levels of phytohormones and copper concentrations.

    摘要: Methods for transforming plants, particularly commercially important elite maize inbreds, are provided. The methods involve transformation of meristematic organogenic tissue or immature embryos, and include the use of defined plant growth media. The methods disclosed provide more stable transgenic plants, and permit the transformation of varieties of cereals that are not amenable to transformation by conventional approaches.
