Modulating light response pathways in plants, increasing light-related tolerances in plants, and increasing biomass in plants

A plant cell comprising an exogenous nucleic acid,

• said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence encoding a polypeptide having 80 percent or greater sequence identity to an amino acid sequence selected from the group consisting of SEQ ID NO:3, SEQ ID NO:634, SEQ ID NO:953, SEQ ID NO:1540, and SEQ ID NO:1635;
• wherein a plant produced from said cell has increased low light tolerance or SD+EODFR tolerance as compared to a control plant that does not comprise said nucleic acid.

A plant comprising an exogenous nucleic acid, said exogenous nucleic acid comprising:

• (a) a nucleotide sequence encoding a polypeptide having 80 percent or greater sequence identity to an amino acid sequence selected from the group consisting of SEQ ID NO:3, SEQ ID NO:634, SEQ ID NO:953, SEQ ID NO:1540, and SEQ ID NO:1635;
• wherein the plant has increased low light tolerance or SD+EODFR tolerance as compared to a control plant that does not comprise said nucleic acid.
