Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

ABSTRACT Microalgae are promising platforms for producing diverse biocompounds relevant to multiple commercial sectors, and the use of genomic technologies in microalgae is rapidly expanding. To examine the research trends, we conducted a bibliographic analysis (systematic map) of this rapidly developing field. Our study presents a descriptive overview

Effect of Nitrogen-Fixing Cyanobacteria on the Growth of Wheat Crop [PDF]
Isolation and purification of cyanobacteria from kafr El-Sheikh soil samples revealed that, two isolates (Anabaena cylindrica and Nostoc clacicola) were acquired as bacterial free cyanobacteria and nitrogen fixed.

Abstract The degree to which N2‐fixation compensates for reduced external nitrogen loading has significant implications for eutrophication recovery. We analyzed 45 years of monitoring data from the shallow, polymictic Lake Müggelsee during which external P‐ and N‐loading declined by about 80% and there were extended periods of N‐limitation in summer ...

Photoreactions and Structural Changes of Anabaena Sensory Rhodopsin [PDF]
Anabaena sensory rhodopsin (ASR) is an archaeal-type rhodopsin found in eubacteria. The gene encoding ASR forms a single operon with ASRT (ASR transducer) which is a 14 kDa soluble protein, suggesting that ASR functions as a photochromic sensor by activating the soluble transducer. This article reviews the detailed photoreaction processes of ASR, which

Abstract The C : N : P of nitrogen‐fixing cyanobacteria regulates phosphate‐limited nitrogen fixation in the ocean yet the causes and range in variation C : N : P is not well constrained. Here we quantify the C : N : P and underlying macromolecular composition of Crocosphaera.

Ecological niches and biogeography of nitrogen‐fixing plants in Europe
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Phycobilisomes: modular light‐harvesting systems of cyanobacteria and red algae
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...

Shifting ice phenology and ice extent linked to harmful algal bloom severity
Abstract Ice cover on lakes can have far‐reaching and profound effects on ecosystem structure and function. However, the duration and spatial extent of ice cover is changing rapidly with warming aquatic ecosystems. This loss of ice creates an urgent need to understand how lakes will function without ice cover, both during the ice‐on and ice‐free season,
