Appl Environ Microbiol
. 2014 May;
80(14):4286-93.
PMID: 24814784
To evaluate the dose-response effects of endogenous indole-3-acetic acid (IAA) on Medicago plant growth and dry weight production, we increased the synthesis of IAA in both free-living and symbiosis-stage rhizobial...

Microbiology (Reading)
. 2006 Jul;
152(Pt 8):2421-2431.
PMID: 16849805
The physiological changes induced by indoleacetic acid (IAA) treatment were investigated in the totally sequenced Escherichia coli K-12 MG1655. DNA macroarrays were used to measure the mRNA levels for all...

Bianco C, Imperlini E, Calogero R, Senatore B, Amoresano A, Carpentieri A, et al.
Arch Microbiol
. 2006 Mar;
185(5):373-82.
PMID: 16555073
Indole-3-acetic acid (IAA) is a ubiquitous molecule playing regulatory roles in many living organisms. To elucidate the physiological changes induced by IAA treatment, we used Escherichia coli K-12 as a...

J Biotechnol
. 2001 Sep;
91(2-3):223-36.
PMID: 11566393
The ultimate objective of PhIMED, in which two European (Germany, Italy) and two Mediterranean (Morocco, Egypt) countries collaborate, is to improve the cultivation of French bean (Phaseolus vulgaris) under arid...

Pandolfini T, Storlazzi A, Calabria E, Defez R, Spena A
Mol Microbiol
. 2000 Apr;
35(6):1326-34.
PMID: 10760134
Agrobacterium rhizogenes transfers DNA (T-DNA) from its Ri plasmid to plant cells. All T-DNA genes are expressed in plant cells. The rolA gene is the only T-DNA gene that contains...

LUKA S, Patriarca E, Riccio A, Iaccarino M, Defez R
J Bacteriol
. 1996 Dec;
178(24):7138-43.
PMID: 8955394
Rhizobium bacteria fix atmospheric nitrogen during symbiosis with legume plants only after bacterial division is arrested. The role of the major vegetative sigma factor, SigA, utilized by Rhizobium bacteria during...

Martino M, Riccio A, Defez R, Iaccarino M, Patriarca E
FEBS Lett
. 1996 Jun;
388(1):53-8.
PMID: 8654590
Rhizobium sigma vegetative-dependent promoters are different from those of enteric bacteria and have never been characterized before. We report here the biochemical characterization of the ORF1-ntrBC promoter of Rhizobium etli....

FEBS Lett
. 1994 Oct;
354(1):89-92.
PMID: 7957908
The DNA-binding activity of the NtrC protein can be demonstrated in gel retardation assays with concentrated protein extracts of Rhizobium etli. Using extracts from either the wild type or a...

Mol Microbiol
. 1994 Feb;
11(4):685-93.
PMID: 7910937
We isolated a Rhizobium leguminosarum mutant strain altered in the glnB gene. This event, which has never been described in the Rhizobiaceae, is rare in comparison to mutants isolated in...

330(1):95-8.
PMID: 8370467
Permeabilization with cetyl trimethyl ammonium bromide was used to study the post-translational modification of the PII protein in Rhizobium leguminosarum. Upon incubation with radioactive UTP a single band was obtained...
