"CHARACTER REMOVAL CONSTRUCT, METHOD FOR REMOVING A TRANSGENE THAT CODES A GENERAL CHARACTER IN A PLANT CELL, METHOD FOR CONDITIONAL ACTIVATING A TRANSGENE IN A SECOND GENERATION PLANT, A TRANSITIONAL METHOD OF TRANSACTION FOR ETHICAL EXPRESSION FOR THE CONDITIONAL EXPRESSION OF MALE STERILITY IN THE FIRST GENERATION PLANT, METHOD FOR EXPRESSING THE CONDITIONAL MALE STERILITY IN THE FIRST AND SECOND GENERATIONS, METHOD OF EXPRESSING THE CONDITIONAL MALE STERILITY IN A PLAN, A METHOD OF REMOVAL TRANSFORMATION MARKER, METHOD FOR CONDITIONAL GAMETOPHYTIC EXPRESSION OF MALE STERILITY, METHOD FOR CONDITIONAL EXPRESSION OR EXCISION OF A TRANSGENE IN A PLANT AND METHOD FOR THE SPECIFIC EXPRESSION OF A "GERMINATIVE TRANSLATION LINE. The present invention presents constructs for conditional or regulated expression or excision of transgenes in plants using site-specific recombinase systems. The constructs comprise a variety of constitutive, induced, specific tissue and developmental stage promoters operationally linked to a transgene or to the elements of one or more site-specific recombinase systems. Through the combination of promoters, responsive to various inducers, plant tissues or stages of plant development with recombinase systems, blocking fragments and transgenes, virtually any character can be expressed or excised at any stage of plant development or at any stage. plant generation.
