A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses [PDF]

open access: yes, 2002
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs,

Pulsed-field gel electrophoresis studies of Rhizobiaceae

open access: yes, 2018
The migration properties of circular, covalently closed (ccc) and linear DNAs were studied in pulsed-field gel electrophoresis as a model system for resolving large plasmids in the Rhizobiaceae. The effects of varying pulse time and agarose concentration on the electrophoretic mobility cccDNAs, ranging from 2 kilobase pairs (kb) to 16 kb, was ...

The ntrPR Operon of Sinorhizobium meliloti Is Organized and Functions as a Toxin-Antitoxin Module

open access: yesMolecular Plant-Microbe Interactions, 2006
The chromosomal ntrPR operon of Sinorhizobium meliloti encodes a protein pair that forms a toxin-antitoxin (TA) module, the first characterized functional TA system in Rhizobiaceae. Similarly to other bacterial TA systems, the toxin gene ntrR is preceded

Apparent N Balance in Organic and Conventional Low Input Cropping Systems [PDF]

open access: yes, 2007
The determination of nutrient surplus is one of the indicators of potential N losses from the agricultural system to the environment. An experiment was started in 1998 in Central Italy to evaluate the soil surface N balance of an organic and a ...
