Abstract: The present invention includes modified phytochrome A (PHYA) nucleic acid molecules in which DNA sequences coding for “active site” amino acid residues have been mutated to generate hyperactive phytochromes. In particular; a serine/threonine residue at the hinge between the N- and C-terminal domains as well as at the N-terminal serine/threonine cluster of phytochromes (e.g., serine-598 and serine-7 in oat phytochrome A) for (a) Pr/Pfr-dependent phosphorylation and (b) dephosphorylation by a phytochrome phosphatase (PP2A) was substituted with alanine. (c) In addition, amino acid residues within the phytochrome chromophore pocket are mutated to generate the bathchromic shift of the Pr-absorption band of both wild type and above-mentioned mutant phytochromes.
