Abstract
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.
