Transgenic plants with controlled distribution of a trait to progeny

A process of producing transgenic multi-cellular plants or parts thereof expressing a trait (1) and a trait (2) of interest, wherein said process comprises

• (i) producing a first plant having in a first locus of a nuclear chromosome a first heterologous nucleotide sequence comprising:
• a first fragment of a nucleotide sequence encoding trait (1) and a first fragment of a nucleotide sequence encoding trait (2);
• (ii) producing a second plant 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 a nucleotide sequence encoding trait (1) and a second fragment of a nucleotide sequence encoding trait (2);
• and
• (iii) hybridising said first and said second plant to generate progeny exhibiting said functional trait (1) due to intein-mediated trans-splicing between a protein or polypeptide encoded by said first fragment of a nucleotide sequence encoding trait (1) and a protein or polypeptide encoded by said second fragment of a nucleotide sequence encoding trait (1);
• and exhibiting said functional trait (2) due to intein-mediated trans-splicing between a protein or polypeptide encoded by said first fragment of a nucleotide sequence encoding trait (2) and a protein or polypeptide encoded by said second fragment of a nucleotide sequence encoding trait (2);
• trait (1) being a selectable marker and trait (2) being male sterility.
