Abstract: The ability of plants to use photoreceptors, such as phytochrome, to sense and respond to changes in light quality and intensity is essential for their survival and photosynthetic efficiency. Activation of photoreceptors by the right wavelength of light causes plants to alter their development and physiological processes, such as enzyme activity and gene expression. Phytochrome mediates responses to red (640-680 run) and far-red (>680 nm) light and some effects of blue light and ultraviolet radiation. It has been previously shown that the expression of specific genes encoded in chloroplast DNA is activated by light. These genes include rbcL (encodes the large subunit of Rubisco responsible for C02 fixation) and 16s rrn(encodes RNAs for ribosomal subunits needed for protein synthesis). However, very little information is available on the wavelength of light involved in activating gene expression and whether gene transcription is activated or mRNA stability is enhanced.
