Patent application filed by The Department of Primary Industries of Queensland
The present disclosure refers to transformation of monocot cells through Agrobacterium. The explant to be transformed can be from any monocotyledonous plant. An advantage of the disclosed method according to the applicant is that the transformed monocot cells form an organogenic callus instead of an embryogenic callus. A modified monocot plant is regenerated from the organogenic callus formed by the selected transformed plant cells.
The application does not provide a definition for either organogenic or embryogenic callus. According to commonly accepted definitions in the scientific literature (which may or may not be used to construe the patent claims), during the development of an organogenic callus, the shoot or root organ, usually a shoot, is induced to form first, followed by root or shoot formation from that shoot or root. In an embryogenic callus type, embryo-like structures develop, called somatic embryos, that then simultaneously develop shoots and roots. Use of embryogenic callus, according to the applicant, is time consuming, labor intensive and not always successful.
