RESOURCE USE EFFICIENCY IMPROVEMENT IN PLANTS

摘要

Polynucleotides and polypeptides incorporated into expression vectors are introduced into plants and were ectopically expressed. These polypeptides may confer at least one regulatory activity and increased yield, increased resource use efficiency, increased water use efficiency, increased light use efficiency, increased photosynthetic capacity, increased photosynthetic rate, increased photosynthetic resource use efficiency, greater vigor, and/or greater biomass as compared to a control plant.

主权项

1. A transgenic plant having greater photosynthetic resource use efficiency than a control plant;
wherein the transgenic plant comprises an exogenous recombinant polynucleotide comprising a photosynthetic tissue-enhanced promoter and a nucleic acid sequence that encodes a polypeptide comprising SEQ ID NOs: 2, 62, 106, 138, 174, 204, 246, or 282, or SEQ ID NOs: 2n where n=1 to 164; wherein the promoter regulates expression of the polypeptide in a photosynthetic tissue to a level that is effective in conferring greater photosynthetic resource use efficiency in the transgenic plant relative to the control plant; wherein the control plant does not comprise the recombinant polynucleotide; wherein the promoter does not regulate protein expression in a constitutive manner; and wherein expression of the polypeptide under the regulatory control of the promoter confers greater photosynthetic resource use efficiency in the transgenic plant relative to the control plant.
