The shift in plants from vegetative growth to floral development is regulated by red-far-red light receptors (phytochromes) and blue-ultraviolet A (cryptochromes). mutation the Arabidopsis thaliana CRY2 gene encoding a blue-light receptor apoprotein (CRY2) allelic late-flowering mutant, fha. Flowering cry2/fha mutant only incompletely responsive photoperiod. Cryptochrome 2 (cry2) positive regulator of flowering-time CO, expression which Analysis flowering cry2 phyB mutants response different wavelengths indicated that antagonistic actions cry2.
