Identification of Novel Candidate Genes Associated With the Symbiotic Compatibility of Soybean With Rhizobia Under Natural Conditions. [PDF]

open access: yesPlant Direct
ABSTRACT A robust symbiotic relationship between soybean and rhizobia can enhance the yield and quality of soybeans by reducing nitrogen fertilizer input, thereby contributing to sustainable agriculture. However, the genetic interplay between soybean cultivars and the rhizobial species colonizing their roots under natural conditions is yet to be ...

Sinorhizobium fredii Strains HH103 and NGR234 Form Nitrogen Fixing Nodules With Diverse Wild Soybeans (Glycine soja) From Central China but Are Ineffective on Northern China Accessions [PDF]

open access: yes, 2018
Sinorhizobium fredii indigenous populations are prevalent in provinces of Central China whereas Bradyrhizobium species (Bradyrhizobium japonicum, B. diazoefficiens, B. elkanii, and others) are more abundant in northern and southern provinces.

Insights on biotic and abiotic 2,4‐dichlorophenoxyacetic acid degradation by anaerobic iron‐cycling bacteria

open access: yesJournal of Environmental Quality, Volume 52, Issue 6, Page 1092-1101, November/December 2023., 2023
Abstract The use of the phenoxy herbicide 2,4‐dichlorophenoxyacetic acid (2,4‐D) has been steadily increasing in recent years due to its selectivity against broad‐leafed weeds and use on genetically modified crops resistant to 2,4‐D. This increases the likelihood of 2,4‐D persisting in agriculturally impacted soils, sediments, and aquatic systems ...

Atypical homodimerization revealed by the structure of the (S)‐enantioselective haloalkane dehalogenase DmmarA from Mycobacterium marinum

open access: yesActa Crystallographica Section D, Volume 79, Issue 11, Page 956-970, November 2023., 2023
Crystallographic structures of the (S)‐enantioselective haloalkane dehalogenase DmmarA from the waterborne pathogenic microbe Mycobacterium marinum were determined at 1.6 and 1.85 Å resolution. The structures reveal a previously unobserved mode of homodimerization, which is predominantly mediated through unusual L5‐to‐L5 loop interactions.Haloalkane ...

Multimeric structure of a subfamily III haloalkane dehalogenase‐like enzyme solved by combination of cryo‐EM and x‐ray crystallography

open access: yesProtein Science, Volume 32, Issue 10, October 2023., 2023
Abstract Haloalkane dehalogenase (HLD) enzymes employ an SN2 nucleophilic substitution mechanism to erase halogen substituents in diverse organohalogen compounds. Subfamily I and II HLDs are well‐characterized enzymes, but the mode and purpose of multimerization of subfamily III HLDs are unknown.

Isolation, characterization and selection of indigenous Bradyrhizobium strains with outstanding symbiotic performance to increase soybean yields in Mozambique. [PDF]

open access: yes, 2017
Article purchasedSoybean inoculation with effective rhizobial strains makes unnecessary the use of N-fertilizers in the tropics. A frequently reported problem is the failure of the inoculant strains to overcome the competition imposed by indigenous ...
