    Characterization of Bradyrhizobium japonicum chromosomal genes involved in the regulation of hup gene expression in free-living conditions and in controlling hydrogenase activity

    Nucleotide sequence analysis of Bradyrhizobium japonicum chromosomal DNA, 9 kb downstream of the hup genes (hydrogenase structural genes), revealed one incomplete and three complete open reading frames. These wer...

    Quantitative Measurement of Azospirillum Plant Cell Attachment

    A quantitative plant assay system is described for measuring the attachment of Azospirillum spp. to plant cells. The attachment of different Azospirillum strains was assayed by mixing 14C-leucine labeled bacteria...

    The density distribution of gene loci over the genetic map ofEscherichia coli: Its structural, functional and evolutionary implications

    A quantitative analysis was carried out on the dispersion of gene loci over theE. coli genetic map. Therefore, the map was divided into regions characterized by an homogeneous gene density. This created a distrib...
