A study was conducted to measure concentrations of potentially active ceftiofur derivatives, in plasma, in uterine tissues (endometrium and caruncles) and in uterine secretions at different time points after a single subcutaneous administration of ce

In a previous study, we showed that in bacteroids, transcription of the inducible nod genes does not occur and expression of nodD is decreased by 65% (H. R. M. Schlaman, B. Horvath, E. Vijgenboom, R.J.H. Okker, and B. J. J. Lugtenberg, J. Bacteriol.

By the use of antibodies raised against a fusion protein of lacZ'-nodI (produced in Escherichia coli) which specifically react with NodI protein, it was shown that in wild-type Rhizobium leguminosarum biovar viciae NodI protein (i) is recovered with

The highly conserved nod box sequence in the promoters of the inducible nodulation genes of rhizobia is required for transcription activation together with NodD, a LysR-type transcriptional regulator, and a flavonoid as a coinducer. DNA fragments con

The expression of nod genes of Rhizobium leguminosarum bv. viciae in nodules of Pisum sativum was investigated at both the translational and transcriptional levels. By using immunoblots, it was found that the levels of NodA, NodI, NodE, and NodO prot

Expression ofnodgenes during symbiosis: The expression of inducible nod genes of Rhizobium requires three components: (i) an inducible nod gene promoter, (ii) a functional nodD gene, whose product acts as a positive regulator when activated, and (iii

Thirty Tn5- or Tn1831-induced nodulation (nod) mutants of Rhizobium leguminosarum were examined for their genetic and symbiotic properties. Thirteen mutants contained a deletion in Sym plasmid pRL1JI. These deletions cover the whole nod region and ar

The symbiosis between bacteria of the genus Rhizobium and their leguminous host plants results in the formation of root nodules in a species-specific way, in that a particular bacterial species can nodulate only a limited number of host species. In f
