amoA-based consensus phylogeny of ammonia-oxidizing archaea and deep sequencing of amoA genes from soils of four different geographic regions
Ammonia-oxidizing archaea (AOA) play an important role in nitrification and many studies exploit their amoA genes as marker for their diversity and abundance. We present an archaeal amoA consensusExpand
Living inside plants: bacterial endophytes.
As current research activities have focused on symbiotic or parasitic plant-microbe interactions, other types of associations between plants and microorganisms are often overlooked. EndophyticExpand
Root colonization and systemic spreading of Azoarcus sp. strain BH72 in grasses.
The invasive properties of Azoarcus sp. strain BH72, an endorhizospheric isolate of Kallar grass, on gnotobiotically grown seedlings of Oryza sativa IR36 and Leptochloa fusca (L.) Kunth were studied.Expand
Azoarcus gen. nov., Nitrogen-Fixing Proteobacteria Associated with Roots of Kallar Grass (Leptochloa fusca (L.) Kunth), and Description of Two Species, Azoarcus indigens sp. nov. and Azoarcus
Among the nitrogen-fixing bacteria associated with roots of Leptochloa fusca (L.) Kunth in saline-sodic soils in the Punjab of Pakistan, we repeatedly found yellow-pigmented, straight to curved,Expand
Complete genome of the mutualistic, N2-fixing grass endophyte Azoarcus sp. strain BH72
Azoarcus sp. strain BH72, a mutualistic endophyte of rice and other grasses, is of agrobiotechnological interest because it supplies biologically fixed nitrogen to its host and colonizes plants inExpand
Endophytic colonization of rice by a diazotrophic strain of Serratia marcescens.
Six closely related N2-fixing bacterial strains were isolated from surface-sterilized roots and stems of four different rice varieties. The strains were identified as Serratia marcescens by 16S rRNAExpand
Life in grasses: diazotrophic endophytes.
N2-fixing bacteria such as Azoarcus spp., Herbaspirillum spp, and Acetobacter diazotrophicus can infect the interior of gramineous plants without causing symptoms of plant disease but do not surviveExpand
Azoarcus grass endophytes contribute fixed nitrogen to the plant in an unculturable state.
The extent to which the N2-fixing bacterial endophyte Azoarcus sp. strain BH72 in the rhizosphere of Kallar grass can provide fixed nitrogen to the plant was assessed by evaluating inoculated plantsExpand
Effect of N-fertilization, plant genotype and environmental conditions on nifH gene pools in roots of rice.
Terminal restriction fragment length polymorphism (T-RFLP) analysis of PCR-amplified nitrogenase gene (nifH) fragments is a rapid technique for profiling of diazotrophic microbial communities withoutExpand
Comparative genome analysis of Burkholderia phytofirmans PsJN reveals a wide spectrum of endophytic lifestyles based on interaction strategies with host plants
Burkholderia phytofirmans PsJN is a naturally occurring plant-associated bacterial endophyte that effectively colonizes a wide range of plants and stimulates their growth and vitality. Here weExpand
