    Notes: Abstract With a view towards the characterization of microstructural anisotropy of fibrous materials, we have shown that the mean intercept figure for a planarN-net system of straight lines is a convex 2N-sided polygon. A very simple method of constructing the mean intercept figure for a planarN-net system is presented. It is shown, by example, that there is an inversion process by which one may construct a planarN-net system from its mean intercept polygon. The significance of these results with respect to the characterization of microstructural anisotropy of fibrous materials is discussed.

    Notes: Abstract Cotyledons from germinating seeds of the soybean cultivar Peking were inoculated with virulent Agrobacterium tumefaciens strain A281:pZA-7 which carries a wild type Ti plasmid pTiBo542 and a disarmed Ti plasmid (a binary vector)pZA-7 which contains the βglucuronidase (uidA) and neomycin phosphotransferase (nptII) genes. Tumors were produced on all inoculated explants and 82% of these tumor lines were cotransformed by the nptII gene from the binary vector pZA-7 as shown by PCR analysis (18 of 22 lines tested). Eleven of these 18 lines were also resistant to kanamycin. Eleven lines expressed β-glucuronidase activity (GUS), six of which were also kanamycin resistant. Since there is a high rate of coexpression of genes carried by the binary vector, this system provides a simple and rapid method for the expression of genes of interest in transformed soybean tissue which has been used successfully to test constructs designed for soybean transformation.
