    Notes: Summary It has been previously shown that in the genome of maize the multiple copies of the histone H3 and H4 multigenic families are organized into eight to ten subfamilies each containing a variable number of copies. Each subfamily is characterized by a specific proximal environment and thus can be revealed by blot-hybridization with its specific 5′ probe. Restriction fragment length polymorphism (RFLP) combined with monosomic analysis was used to localize several H3 and H4 subfamilies on maize chromosomes. H3 and H4 genes were found to be located on most, possibly all of the chromosomes, revealing a remarkably dispersed organization of these multigenic families.

    Notes: Abstract  The centromere of maize chromosome 4 was previously localized to a 26-cM interval using molecular markers and B-A translocations. The objective of the present study was to refine the placement of the centromere using secondary trisomics. Two independently isolated secondary trisomics (having an isochromosome plus two normal homologs) for 4S were recovered. RFLP analysis of populations segregating for them placed the centromere of chromosome 4 between bnl15.45 and bnl7.20, two RFLP loci that are 5.4-cM apart on the UMC map and 11.5-cM apart on the BNL map.

    The determination of organotin compounds in fruit juices using gas chromatography-atomic absorption spectrometry (1992)

    Notes: A method for extracting butyl-, cyclohexyl-, octyland phenyl-tin compounds in fruit juices was developed using 0.05% tropolone in 25% pentane/diethyl ether. Methyl derivatives formed by Grignard reaction were quantified by gas chromatography-atomic absorption spectrometry. Several fruit juices contained low ng cm-3 levels of butyl- and octyl-tins. Gas chromatography-mass spectrometry, used for the confirmation of the butyl- and octyl-tins, also detected phenyl- and cyclohexyl-tin compounds at levels below the GC AA detection limits (0.03-0.05 ng Sn cm-3).
