摘要： The present disclosure provides a transgenic plant comprising one or more nucleotide sequences encoding polypeptides selected from photosystem II subunit S (PsbS), zeaxanthin epoxidase (ZEP), and violaxanthin de-epoxidase (VDE), operably linked to at least one expression control sequence. Expression vectors for making transgenic plants, and methods for increasing biomass production and/or carbon fixation and/or growth in a plant comprising increasing expression of at least one of PsbS, ZEP and VDE polypeptides are also provided.

摘要： The impact of plastid size change in both monocot and dicot plants has been examined. In both, when plastid size is increased there is an increase in biomass relative to the parental lines. Thus, provided herein are methods for increasing the biomass of a plant, comprising decreasing the expression of at least one plastid division protein in a plant. Optionally, the level of chlorophyll in the plant is also reduced.

摘要： Aspects of the present disclosure relate to methods of cultivating genetically altered plants with increased activity of the PsbS protein. These genetically altered plants have increased water use efficiency and substantially similar photosynthetic efficiency as compared to WT plants grown under the same conditions.

摘要： Disclosed herein are transgenic plants and plant cells having increased photosynthetic rate, increased biomass production, and/or improved cold tolerance compared to control plants (such as non-transgenic plants of the same species as the transgenic plants). In some examples, the transgenic plants/plant cells contain a plant transformation vector including a nucleic acid encoding a pyruvate orthophosphate dikinase (PPDK) polypeptide. Also disclosed herein are methods for making the transgenic plants, for instance by introducing into progenitor cells of the plant a plant transformation vector including a nucleic acid that encodes a PPDK polypeptide, and growing the transformed progenitor cells to produce a transgenic plant, in which the PPDK nucleic acid is expressed. Further disclosed herein are PPDK-encoding nucleic acids, PPDK polypeptides, and plant transformation vectors of use in producing the transgenic plants or plant cells.
