Abstract
The present invention is related to a method for increasing shoot-to-root ratio of a plant comprising the step of inhibiting the activity of an invertase in the root tissue of said plant.
Claims47
A method for increasing shoot-to-root ratio of a plant comprising the step of inhibiting the activity of an invertase in the root tissue of said plant.
A method for increasing seed production of a plant comprising the step of inhibiting the activity of an invertase in the root tissue of said plant.
A method for increasing resistance to a disease of a plant comprising the step of inhibiting the activity of an invertase in the root tissue of said plant.
A nucleic acid molecule, preferably coding for an invertase, having a nucleic acid sequence, whereby be nucleic acid sequence is selected from the group of nucleic acid sequences SEQ.ID.No. 1 to 36, or a nucleic acid essentially complementary thereto.
Use of a nucleic acid construct for the modification of the genome of a plant, whereby the construct comprises
- (i) a root specific promoter;
- and
- (j) a nucleic acid coding for an invertase inhibitor,
- wherein the promoter and the nucleic acid coding for the invertase are operably linked to each other.
Use of a nucleic acid construct for inhibiting the activity or presence of an invertase, preferably an invertase in root and/or root tissue, whereby the construct comprises
- (k) a root specific promoter;
- and
- (l) a nucleic acid coding for an invertase inhibitor,
- wherein the promoter and the nucleic acid coding for the invertase are operably linked to each other.
Use of a nucleic acid construct for increasing shoot-to-root ratio, seed production and/or resistance to disease of a plant, whereby the construct comprises
- (m) a root specific promoter;
- and
- (n) a nucleic acid coding for an invertase inhibitor,
- wherein the promoter and the nucleic acid coding for the invertase are operably linked to each other.
Use of a nucleic acid construct for the manufacture of a medicament for the treatment of a plant disease, whereby the construct comprises
- (o) a root specific promoter;
- and
- (p) a nucleic acid coding for an invertase inhibitor,
- wherein the promoter and the nucleic acid coding for the invertase are operably linked to each other.
Use of a nucleic acid construct for the generation of a transgenic plant, whereby the transgenic plant preferably shows one or more of an increase in shoot-to-root ratio, increase in seed production and increase in resistance to pathogens and/or diseases.
