Abstract: Disclosed is a PHD protein regulating the differentiation of plant phloem; a recombinant vector containing a gene encoding the same; a plant transformed with the recombinant vector; a seed of the plant; and a method for regulating the development and formation of plant phloem by using the gene encoding the PHD protein. Regulated is the development of phloem, which plays the role in moving a photosynthetic product and finally storing the same in starch and sugar forms in a plant storage organ, so as to regulate the function of phloem, thereby having an effect of controlling the size and storage capacity of the plant storage organ. The development of phloem can be improved by allowing the PHD gene to be silent in plants, and thus it is expected that the function of plant phloem can be increased through the regulation of PHD gene expression by using genetic engineering techniques.

A method and apparatus for increasing transmission capacity are needed, which can transmit a large-capacity high-speed signal in order to transmit a signal through a united OTN by adapting signals from various tributary signal networks which have been independently operated for voice, image, or data transmission. Although various types of techniques such as Time Division Multiplexing (TDM), Wavelength Division Multiplexing (WDM), and an optical Printed Circuit Board (PCB) method have been performed, the techniques have various limitations. Therefore, a method and apparatus is provided for embodying a large-capacity optical transmission network, which overcome the limitations by using a Virtual Concatenation (VC) method.

Abstract: The present invention relates to none return to zero (NRZ) modulation method. The NRZ optical modulation is performed by combining a clock signal and NRZ data at a sending end and signal distortion capable of being generated when the clock signal and the NRZ data are combined is optimized by controlling the magnitude and phase of the clock signal. At the receiving end, the clock signal is extracted by performing narrow band band-pass filtering of the detected optical signal transmitted from a transmitter and data is recovered using the clock signal. Therefore, a receiver structure for clock extraction is simpler, an error rate of data recovery is lower by clearly extracting the clock signal, and transmission distance of the optical signal is longer.
