Survival of Azorhizobium caulinodans in the Soil and Rhizosphere of Wetland Rice under Sesbania rostrata-Rice Rotation.

Azorhizobium caulinodans Transmembrane Chemoreceptor TlpA1 Involved in Host Colonization and Nodulation on Roots and Stems

Azorhizobium caulinodans ORS571 is a motile soil bacterium that interacts symbiotically with legume host Sesbania rostrata, forming nitrogen-fixing root and stem nodules. Bacterial chemotaxis plays an important role in establishing this symbiotic relationship. To determine the contribution of chemotaxis to symbiosis in A. caulinodans ORS571-S. rostrata, we characterized the function of TlpA1 (t...

A Chemotaxis Receptor Modulates Nodulation during the Azorhizobium caulinodans-Sesbania rostrata Symbiosis.

UNLABELLED Azorhizobium caulinodans ORS571 is a free-living nitrogen-fixing bacterium which can induce nitrogen-fixing nodules both on the root and the stem of its legume host Sesbania rostrata This bacterium, which is an obligate aerobe that moves by means of a polar flagellum, possesses a single chemotaxis signal transduction pathway. The objective of this work was to examine the role that ch...

Effect of Sesbania rostrata on Hirschmanniella oryzae in Flooded Rice.

Microplot experiments on flooded soil infested with Hirschmanniella oryzae were conducted to investigate the influence of the legum Sesbania rostrata as a rotation crop with rice, Oryza sativa L. cv. Moroberekan. To avoid a green manure effect from S. rostrata, all aerial parts were removed at harvest. The dry weight of paddy, culms and leaves, and number of culms of rice following Sesbania wer...

Comparative transcriptome analysis reveals common and specific tags for root hair and crack-entry invasion in Sesbania rostrata.

The tropical legume Sesbania rostrata provides its microsymbiont Azorhizobium caulinodans with versatile invasion strategies to allow nodule formation in temporarily flooded habitats. In aerated soils, the bacteria enter via the root hair curling mechanism. Submergence prevents this epidermal invasion by accumulation of inhibiting concentrations of ethylene and, under these conditions, the bact...
