Abstract

A process of producing transgenic multi-cellular plants or parts thereof expressing a trait of interest that has a controlled distribution of said trait to progeny, comprising (i) producing a first plant or a cell thereof having in a first locus of a nuclear chromosome a first heterologous nucleotide sequence comprising a first fragment of a nucleotide sequence encoding said trait of interest, (ii) producing a second plant or a cell thereof having in a second locus of a nuclear chromosome homologous to said nuclear chromosome of step (i), a second heterologous nucleotide sequence comprising a second fragment of the nucleotide sequence encoding said trait of interest, and (iii) hybridising said first and said second plants or cells thereof to generate progeny exhibiting said functional trait of interest. Also disclosed is a process of producing hybrid seeds for agriculture.
