or plant tissues in order to prime said plants immune system as used herein the term u201c homologous u201d or u201c homology u201d denotes structural similarity between two macromolecules particularly between two polynucleotides irrespective of whether said similarity is or is not due to shared ancestry conventionally homology denotes the level of sequence identity measured in percent sequences that are substantially homologous can be identified by comparing the sequences using standard software available in sequence data banks or in a southern hybridization experiment under for example stringent conditions as defined for that particular system defining appropriate hybridization conditions is within the skill of the art see e g sambrook et al 1989 supra the regeneration development and cultivation of plants from single plant protoplast transformants or from various transformed explants is well known in the art weissbach and weissbach in methods for plant molecular biology academic press san diego calif 1988 this regeneration and growth process typically includes the steps of selection of transformed cells culturing those individualized cells through the usual stages of embryonic development through the rooted plantlet stage transgenic embryos and seeds are similarly regenerated the resulting transgenic rooted shoots are thereafter planted in an appropriate plant growth medium such as soil in yet another aspect plants derived from any method of the present invention can be used for the production of seeds fruits stems roots and leaves or other plant derived products the present invention will now be further described in the following examples with reference to the accompanying figures and sequences nevertheless without being limited thereto for the purposes of the present invention all references as cited herein are incorporated by reference in their entireties.
