Corn plant event MON87460 and compositions and methods for detection thereof

A method of producing a drought tolerant corn plant, the method comprising crossing a drought tolerant first parent corn plant comprising a SEQ ID NO:1 and a heterologous transgenic insert comprising a truncated rice actin promoter that is operably linked to a cspB gene, and a second parent corn plant, thereby producing a plurality of drought tolerant progeny plants.

A method for obtaining a water deficit tolerant corn plant that lacks an intact selectable marker gene comprising the steps of:

• exposing a corn chromosome comprising SEQ ID NO:1 and a heterologous transgene insert to one or more recombination-inducing agents, wherein said heterologous transgene insert comprises a truncated rice actin promoter that is operably linked to a cspB gene, and a selectable marker gene;
• selecting a corn plant comprising SEQ ID NO:1 and a truncated rice actin promoter that is operably linked to a cspB gene wherein said selectable marker gene or a portion thereof has been eliminated or disrupted, thereby obtaining a water deficit tolerant corn plant that lacks an intact selectable marker gene.
