Richelia intracellularis is a symbiotic heterocystous cyanobacterium that is capable of forming associations with several genera of diatoms. nifH, 16S rRNA and hetR sequences were amplified and cloned from field populations of Richelia associated with Hemiaulus hauckii (N. Atlantic), with Rhizosolenia clevei (N. Pacific), and from a cultivated isolate of Calothrix associated with Chaetoceros from station ALOHA (N. Pacific). Sequence identity was highest (98.2%) among the 16S rRNA sequences, and… Expand
Isolation and Characterization of a Rhizobium Bacterium Associated with the Toxic Dinoflagellate Gambierdiscus balechii
TLDR
This study detects, isolated, and characterized a Rhizobium species from the toxic benthic dinoflagellate Gambierdiscus culture, the first report of such bacterium being recorded to be associated with a din oflageLLate in this genus, providing new insights into the dinof lagellates-bacteria association for future research.

Microbiome of Trichodesmium Colonies from the North Pacific Subtropical Gyre
TLDR
It is proposed that the unique microbial consortium inhabiting colonies has a significant impact on the biogeochemical functioning of Trichodesmium colonies in pelagic environments. Expand
The genetic diversity and evolution of diatom-diazotroph associations highlights traits favoring symbiont integration
TLDR
The evolutionary nature of DDAs is presented and new genetic and phenotypic information for these biogeochemically relevant populations is provided and that the adaptive radiation to the marine environment was likely facilitated by the symbiosis. Expand
The luggage hypothesis: Comparisons of two phototrophic hosts with nitrogen-fixing cyanobacteria and implications for analogous life strategies for kleptoplastids/secondary symbiosis in dinoflagellates
TLDR
It is shown that dinoflagellates are organisms that exemplify both types of strategies that is either preying or harbouring a permanent organelle, and the luggage theory offers an explanation to why some dinof lagellate species contain kleptoplastids, while others have permanent, secondary plastids and some have tertiaries.

Epiphytic cyanobacteria of the seagrass Cymodocea rotundata: diversity, diel nifH expression and nitrogenase activity.
TLDR
Data show that C. rotundata is colonized by diverse diazotrophic cyanobacteria species and suggest that these may be beneficial partners of seagrasses in nitrogen-depleted waters, which combined nitrogen may limit their production. Expand
Genomic deletions disrupt nitrogen metabolism pathways of a cyanobacterial diatom symbiont
TLDR
The genome of Richelia is an example of metabolic streamlining that has implications for the evolution of N2-fixing symbiosis and potentially for manipulating plant–cyanobacterial interactions. Expand
Trichome Lengths of the Heterocystous N2-Fixing Cyanobacteria in the Tropical Marginal Seas of the Western North Pacific
Calothrix rhizosoleniae and Richelia intracellularis are heterocystous cyanobacteria found in the tropical oceans. C. rhizosoleniae commonly live epiphytically on diatom genera Chaetoceros (C-C) andExpand
C 5 glycolipids of heterocystous cyanobacteria track symbiont abundance in the diatom Hemiaulus hauckii across the tropical North Atlantic
TLDR
The presence of the same C5 HGs in surface sediment provides evidence that they are effectively transported to the sediment and hence have potential as biomarkers for studies of the contribution of DDAs to the paleo-marine N cycle. Expand
Comparative genomics reveals surprising divergence of two closely related strains of uncultivated UCYN-A cyanobacteria
TLDR
The results suggest that UCYN-A1 and UCyn-A2 had a common ancestor and diverged after genome reduction, suggesting that these two variants may reflect adaptation of the host to different niches, which could be coastal and open ocean habitats. Expand

Host specificity in the Richelia-diatom symbiosis revealed by hetR gene sequence analysis.
TLDR
Sequences from R. intracellularis-Hemiaulus membranaceus sampled in the Atlantic and Pacific Oceans were almost identical, demonstrating that the genetic relatedness was not dependent on geographical location and all sequences displayed a deep divergence between symbionts from different genera and a high degree of host specificity.

Resolution of Prochlorococcus and Synechococcus Ecotypes by Using 16S-23S Ribosomal DNA Internal Transcribed Spacer Sequences
TLDR
The results provide further evidence that natural populations of Prochlorococcus and Synechococcus consist of multiple coexisting ecotypes, genetically closely related but physiologically distinct, which may vary in relative abundance with changing environmental conditions. Expand

Temporal Patterns of Nitrogenase Gene (nifH) Expression in the Oligotrophic North Pacific Ocean
TLDR
The temporal separation of nifH expression by the various phylotypes suggests that open ocean diazotrophic cyanobacteria have unique in situ physiological responses to daily fluctuations of light in the upper ocean. Expand
