Transporter proteins for oxoderivatives of nitrogen-containing heterocyclic compounds and coding nucleic acids

摘要

Nucleic acid (I) comprising a coding region for a transport protein for nitrogenous heterocyclics, particularly their oxy-derivatives, where the encoded region binds and transports an oxy-derivative with at least two oxy groups in the ring system excluding caffeine, or at least three oxy groups in the ring system, is new. Independent claims are also included for: (1) nucleic acid has a coding region for a transport protein for nitrogenous heterocyclics, particularly their oxy-derivatives, having: (a) a DNA sequence encoding a peptide having the one of the 17 residue amino acid sequences fully defined in the specification; (b) a sequence complimentary to (a); (c) an RNA or DNA/RNA equivalent of (a); or (d) a sequence which hybridizes to the complement of (a); (2) a nucleic acid construct, vector or mobile genetic element comprising the claimed nucleic acid, preferably in antisense orientation; (3) a host cell comprising the claimed nucleic acid, preferably in antisense orientation; (4) a plant or it's parts transformed with the claimed nucleic acid, preferably in antisense orientation; (5) transgenic seeds from the above transformed plant; (6) a transport protein for nitrogenous heterocyclics, particularly their oxy-derivatives, which binds and transports an oxy-derivative with at least two oxy groups in the ring system excluding caffeine, or at least three oxy groups in the ring system; and (7) producing a transgenic plant comprising introducing the claimed nucleic acid to a plant cell and regenerating a plant from the cell.
