    Notes: The morphology of sodium-neutralized carboxytelechelic ionomers has been characterized by SAXS (small-angle X-ray scattering) for varying degrees of neutralization between 20 and 100%. The good-quality data covering a broad q range have been fitted with a functional form of the intensity. It has been found that the aggregates grow as more chain ends are neutralized while the electron density is kept constant, in agreement with the multiplet model. The excess scattering at small angles was found to vary systematically with the degree of neutralization, confirming the ionic origin of this feature.

    Notes: Abstract Six molecular markers were mapped to a 7.4-cM region of rice chromosome 11 containing the Xa21 gene, which confers resistance to the pathogen Xanthomonas oryzae pv oryzae. Three markers, RG103, 248 and 818, co-segregated with Xa21 in a population of 1141 plants. Multiple copies of all marker loci were present within the region that was introgressed from Oryza longistaminata into O. sativa. The marker loci were cloned and primers were designed that defined sequence-tagged sites. Physical mapping of the three tightly linked central markers revealed that RG103, the marker that hybridizes to the Xa21 gene, resides on a separate DNA fragment from the other two markers.
