  • HIGH-THROUGHPUT EVALUATION OF RUBISCO AND PLANT PHOTOSYNTHETIC PERFORMANCE IN VIVO
    Publication number: 20080271209
    Abstract: The present invention provides a method for determining a level of a RuBP, PGA, 2-PA in a photosynthetic cellular extract by resolving at least one RuBP, PGA, or 2-PA or combinations thereof in a photosynthetic cellular extract obtained from a plant. In another aspect, it provides for detecting at least one resolved RuBP, PGA, or 2-PA or combinations, thereby determining a level of the resolved RuBP, PGA, or 2-PA or combinations. In one aspect the photosynthetic cellular extract is obtained from a plant subjected to an abiotic stress. A method of the invention can be useful, for example, for identifying plants with increased photosynthetic performance. Also included herein is a high throughput system for identifying a plant with increased photosynthetic performance.

  • METHODS OF IDENTIFYING AND CREATING RUBISCO LARGE SUBUNIT VARIANTS WITH IMPROVED RUBISCO ACTIVITY, COMPOSITIONS AND METHODS OF USE THEREOF
    Publication number: 20080256666
    Abstract: Methods for identifying one or more amino acid substitutions in a Rubisco large subunit polypeptide (variant) that confer increased Rubisco activity in a unicellular photosynthetic organism and transferring those substitutions to a Rubisco large subunit polypeptide of a higher plant cell are described herein. Methods and compositions for modulating plant productivity using the modified Rubisco large subunit polypeptide variants are provided. The Rubisco large subunit sequences are used in a variety of methods including increasing plant productivity in a plant. Transformed plants, plant cell, tissues, seed, and expression vectors are also provided.
