Abstract: The present invention relates generally to the field of molecular biology and concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a yield increasing polypeptide selected from the group consisting of: phosphoenolpyruvate carboxylase (PEPC), Class III U-Box protein and PQQC protein. The present invention also concerns plants having modulated expression of a nucleic acid encoding yield increasing polypeptide selected from the group consisting of: phosphoenolpyruvate carboxylase (PEPC), Class III U-Box protein and PQQC protein, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.

Abstract: An expression cassette of selection marker for plant transformation includes the following sequences that are operably linked in a 5? to 3? direction: (i) a promoter sequence; (ii) a coding sequence for an enzyme which degrades toxoflavin; and (iii) a 3?-untranslated terminator sequence. A method of producing a transgenic plant using the above-describe expression cassette includes (i) transforming plant cells with a recombinant vector that includes the above-described expression cassette to produce transgenic plant cells; (ii) proliferating said transgenic plant cells in a media comprising toxoflavin to produce selected transgenic plant cells; and (iii) growing a transgenic plant from said selected transgenic plant cells.

Abstract: The present invention relates to an agent for controlling plant diseases containing vitamin B1, or salts or derivatives thereof as an active ingredient, which exhibits excellent disease controlling effects by rapid induction of defense-related genes in plants infected with pathogens.
