Abstract: The present invention provides a purified, homogeneous plant enzyme that adds a ?-1,2-linked xylose to the ?-linked mannose on the N-linked oligosaccharides of storage glycoproteins. This ?1,2-xylosyltransferase was purified from the microsomal fraction of soybean cells approximately 51,000-fold. Also provided is an antibody recognizing this ?1,2-xylosyltransferase.

Abstract: There is disclosed a building structure partially covered with siding panels, the outer surface of which are transparent to solar energy, the panels being slightly spaced from an insulating wall of the building to allow a fluid flow, preferably air, therebetween with effective heat exchange from a solar radiation absorbing surface with the fluid being selectively utilizable for space heating purposes or other purposes. The air can be moved by fans or convection or both. A preferred embodiment employs small horizontal lenticular lenses in the transparent material on the surface of the siding together with a mask, which may be three dimensional, on the back of the siding with the result that when the siding is viewed from the horizontal it displays a decorative color while it is highly reflective for solar rays at high angles of elevation and is transparent for solar rays at low angles of elevation, as during winter months.

Abstract: Description and specifications of a new and distinct nectarine tree variety which originated from an F2 population of seed produced by a hand pollinated cross of Arkansas Peach Selection 190 (non-patented) and Arkansas Nectarine Selection 178 (non-patented) is provided. This new nectarine variety can be distinguished by its large, attractive, very firm fruit, good yielding abilities, good storage and shipping characteristics, and high levels of genetic resistance to the disease bacterial spot.
