Plant light energy conversion efficiency associated protein and encoding gene and application thereof

The invention discloses plant light energy conversion efficiency correlated protein and encoding gene and application thereof. The protein provided by the invention is the protein (a) or (b) as follows: (a) protein with an amino acid sequence shown as the sequence 1 in a sequence table; or (b) protein which is derived from the sequence 1 by substituting and/or deleting and/or adding one or more amino acid residues on the amino acid sequence as the sequence 1, and is associated with the plant light energy conversion efficiency. The invention provides a method for culturing a transgenic plant, i.e. the encoding gene of the protein is transferred into a target plant to acquire a transgenic plant of which the growing ability and/or light energy conversion efficiency is higher than that of the target plant. The invention provides a genetic material and foundation for researching and acquiring a new species of high photosynthetic resistant and strong stress crop.
