  • NUCLEIC ACID CONSTRUCTS, PLANTS WITH INCREASED TUBER YIELD, AND METHODS FOR INCREASING TUBER YIELD IN A PLANT
    Publication number: 20240093218
    Abstract: The present invention relates to a nucleic acid construct. The nucleic acid construct includes a nucleic acid molecule configured to silence or reduce the expression of StBEL11 and/or StBEL29 and variants thereof, a 5? DNA promoter sequence, and a 3? terminator sequence, where the first nucleic acid molecule, the promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the first nucleic acid molecule. The present invention is also directed to vectors, host cells, transgenic plants, and transgenic plant seeds, as well as non-transgenic mutant plants, and methods for altering tuber yield in a plant.

  • Mobile RNA acts as a signal to regulate plant growth and development
    Patent number: 7579150
    Abstract: The present invention relates to isolated nucleic acid molecules which encode a BEL transcription factor from potato (Solanum tuberosum L.) and the amino acid sequences encoded by such nucleic acid molecules. The present invention also relates to a method of screening a biomolecule for its ability to assist in mediating long-distance movement of a mobile RNA in a plant.

  • POTATO TRANSCRIPTION FACTORS, METHODS OF USE THEREOF, AND A METHOD FOR ENHANCING TUBER DEVELOPMENT
    Publication number: 20080184396
    Abstract: The present invention relates to isolated nucleic acid molecules which encode a BEL transcription factor from potato (Solanum tuberosum L.) and the amino acid sequences encoded by such nucleic acid molecules. Additional aspects of the present invention relate to methods of using isolated nucleic acid molecules which encode BEL transcription factors from potato to enhance growth and to regulate flowering in plants. The present invention is also directed to a method for enhancing tuber development in a plant. This method includes transforming a tuberous plant with a DNA construct including a nucleic acid molecule encoding a BEL transcription factor or a KNOX transcription factor, and an operably linked promoter and 3? regulatory region, whereby tuber development is enhanced in the plant.
