Sarasa-Buisan C, Nieves-Morion M, Arevalo S, Helm R, Sevilla E, Luque I, et al.
mBio
. 2024 Feb;
15(3):e0323123.
PMID: 38334377
Microbial extracellular proteins and metabolites provide valuable information concerning how microbes adapt to changing environments. In cyanobacteria, dynamic acclimation strategies involve a variety of regulatory mechanisms, being ferric uptake regulator...

. 2023 Aug;
14(5):e0098323.
PMID: 37650636
Multicellular organization is a requirement for the development of complex organisms, and filamentous cyanobacteria such as represent a paradigmatic case of bacterial multicellularity. The filament can include hundreds of communicated...

PNAS Nexus
. 2023 Jun;
2(6):pgad194.
PMID: 37383020
A few genera of diatoms are widespread and thrive in low-nutrient waters of the open ocean due to their close association with N-fixing, filamentous heterocyst-forming cyanobacteria. In one of these...

Front Microbiol
. 2022 Apr;
13:799362.
PMID: 35369505
The symbiosis between the diatom and the heterocyst-forming cyanobacterium makes an important contribution to new production in the world's oceans, but its study is limited by short-term survival in the...

Nieves-Morion M, Flores E, Whitehouse M, Thomen A, Foster R
mBio
. 2021 Aug;
12(4):e0131421.
PMID: 34399619
Under diazotrophic conditions, the model filamentous, heterocyst-forming cyanobacterium sp. strain PCC 7120 develops a metabolic strategy based on the physical separation of the processes of oxygenic photosynthesis, in vegetative cells,...

Arevalo S, Nenninger A, Nieves-Morion M, Herrero A, Mullineaux C, Flores E
mSphere
. 2021 Jan;
6(1).
PMID: 33441411
In filamentous heterocyst-forming (N-fixing) cyanobacteria, septal junctions join adjacent cells, mediating intercellular communication, and are thought to traverse the septal peptidoglycan through nanopores. Fluorescence recovery after photobleaching (FRAP) analysis with...

Environ Microbiol
. 2020 Apr;
22(6):2027-2052.
PMID: 32281201
In the open ocean, some phytoplankton establish symbiosis with cyanobacteria. Some partnerships involve diatoms as hosts and heterocystous cyanobacteria as symbionts. Heterocysts are specialized cells for nitrogen fixation, and a...

Life (Basel)
. 2018 Dec;
9(1).
PMID: 30577420
Heterocyst-forming cyanobacteria are multicellular organisms that grow as chains of cells (filaments or trichomes) in which the cells exchange regulators and nutrients. In this article, we review the morphological, physiological...

Environ Microbiol Rep
. 2017 Nov;
10(1):40-48.
PMID: 29159995
Cyanobacteria are generally capable of photoautotrophic growth and are widely distributed on Earth. The model filamentous, heterocyst-forming strain Anabaena sp. PCC 7120 has long been considered as a strict photoautotroph...

. 2017 Jan;
199(7).
PMID: 28096449
When deprived of combined nitrogen, some filamentous cyanobacteria contain two cell types: vegetative cells that fix CO through oxygenic photosynthesis and heterocysts that are specialized in N fixation. In the...
