TLDR
Sufficient information about the relationship of Frankia strains to other bacteria, and to each other, is now available to warrant the creation of some species based on phenotypic and genetic criteria.About:

Plant invasions--the role of mutualisms.
TL;DR: The view that tightly coevolved, plant‐vertebrate seed dispersal systems are extremely rare is supported and perspectives on mutualisms in screening protocols will improve the ability to predict whether a given plant species could invade a particular habitat.

TL;DR: Actinobacteria are Gram-positive bacteria with high G+C DNA content that constitute one of the largest bacterial phyla, and they are ubiquitously distributed in both aquatic and terrestrial ecosystems.

Infection and Invasion of Roots by Symbiotic, Nitrogen-Fixing Rhizobia during Nodulation of Temperate Legumes
TL;DR: Root hair growth, how root hair growth is influenced by rhizobial signaling molecules, infection of root hairs, infection thread extension down root hairs), infection thread growth into root tissue, and the plant and bacterial contributions necessary for infection thread formation and growth are summarized.

TL;DR: Strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies is found, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets.
Journal ArticleDOI
Symbiotic Nitrogen Fixation.
TL;DR: This review describes the early steps of the interaction between rhizobia and legumes that result in the formation of a nitrogen-fixing nodule and focuses on the role of specific lipooligosaccharides secreted by Rhizobia in the induction of these early steps.

The 3′-Terminal Sequence of Escherichia coli 16S Ribosomal RNA: Complementarity to Nonsense Triplets and Ribosome Binding Sites
John Shine,Lynn Dalgarno +1 more
TL;DR: It is suggested that this region of the RNA is able to interact with mRNA and that the 3'-terminal U-U-A(OH) is involved in the termination of protein synthesis through base-pairing with terminator codons.

Biomass Burning in the Tropics: Impact on Atmospheric Chemistry and Biogeochemical Cycles
TL;DR: Widespread burning of biomass serves to clear land for shifting cultivation, to convert forests to agricultural and pastoral lands, and to remove dry vegetation in order to promote agricultural productivity and the growth of higher yield grasses, but it may also disturb biogeochemical cycles, especially that of nitrogen.
Journal ArticleDOI
How close is close: 16S rRNA sequence identity may not be sufficient to guarantee species identity.
TL;DR: Although 16S rRNA sequences can be used routinely to distinguish and establish relationships between genera and well-resolved species, very recently diverged species may not be recognizable.
