Novel plant polysaccharide synthesis genes and polypeptides encoded by such genes are provided. The fluid coupler enables fluid-tight connecting between fixed position components and allows for separating the hydraulic appliances without decoupling the coupler while maintaining fluid-tightness of both appliances after separation. The white video information is altered such that the alteration decreases the amount of power required to display the white video information. Corresponding computer program products and methods are also provided.
