A Complex Regulatory Network Governs the Expression of Symbiotic Genes in Sinorhizobium Fredii HH103
(Frontiers Media, 2023)
Introduction: The establishment of the rhizobium-legume nitrogen-fixing symbiosis relies on the interchange of molecular signals between the two symbionts. We have previously studied by RNA-seq the effect of the symbiotic ...

NolR Regulates Diverse Symbiotic Signals of Sinorhizobium fredii HH103
(The American Phytopathological Society, 2004)
We have investigated in Sinorhizobium fredii HH103-1 (=HH103 Strr ) the influence of the nolR gene on the production of three different bacterial symbiotic signals: Nod factors, signal responsive (SR) proteins, and ...

A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes
(Sociedad Española de Microbiología. Viguera Editores, 2007)
Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media. The mutated gene, pyrF, codes for an ...

Inactivation of the "Sinorhizobium fredii" HH103 "rhcJ" gene abolishes nodulation outer proteins (Nops) secretion and decreases the symbiotic capacity with soybean
(Sociedad Española de Microbiología, Viguera Editores, 2006)
Se ha propuesto que las proteínas externas de nodulación (Nops) impiden la nodulación efectiva de Sinorhizobium fredii USDA257 con las sojas americanas. S. fredii HH103 nodula de forma natural tanto conlas sojas asiáticas ...

A transcriptomic analysis of the effect of genistein on Sinorhizobium fredii HH103 reveals novel rhizobial genes putatively involved in symbiosis
(Nature Publishing Group, 2016)
Sinorhizobium fredii HH103 is a rhizobial soybean symbiont that exhibits an extremely broad host-range. Flavonoids exuded by legume roots induce the expression of rhizobial symbiotic genes and activate the bacterial protein ...
