Growth Characteristics of an Estuarine Heterocystous Cyanobacterium

Frontiers in Microbiology, 2017
A new estuarine filamentous heterocystous cyanobacterium was isolated from intertidal sediment of the Lagoa dos Patos estuary (Brazil). The isolate may represent a new genus related to Cylindrospermopsis.

Cellular differentiation and nitrogenase activity in the cyanobacteriumAnabaena

Biologia Plantarum, 1982
Nitrogenase activity at periods of differentiation of heterocysts and akinetes was assayed by the acetylene reduction technique. There was no nitrogenase activity in ammoniumgrown, non-heterocystousAnabaena sp.; the activity appeared only after a lag-phase of about 17 – 21 h after the ammonium-grown culture had been transferred to medium free of ...

Systems‐Level Plant Responses Reveal Pseudomonas‐Mediated Growth Promotion in Brachypodium Under Nitrogen Limitation

Plant, Cell &Environment, Volume 49, Issue 9, Page 6396-6412, September 2026.
ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...

Survey on nitrogenase evolution by considering the importance of nitrogenase, its structure, and mechanism of nitrogenase

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Nitrogenase is a complicated enzyme that actives the ATP-dependent reduction of dinitrogen (N2) to ammonia (NH3). The aim of this manuscript is to review the nitrogenase evolution with considering nitrogenase, structure of nitrogenase, action mechanism ...

A Plasmonic Biohybrid With an Intracellular Biogenic S‐Scheme Nano‐Heterojunction Toward Wide‐Spectrum Solar‐To‐Chemical Conversion Beyond Nature

Aggregate, Volume 7, Issue 8, August 2026.
Bioinorganic hybrids show promise for solar‐to‐chemical conversion, yet are limited by poor light absorption and charge separation. A plasmonic biohybrid (CuS/CdS@yeast), featuring an intracellular S‐scheme heterojunction to achieve efficient electron‐hole separation, is fabricated via in‐situ mineralization for wide‐spectrum solar‐to‐chemical ...

Functional expression of an oxygen-labile nitrogenase in an oxygenic photosynthetic organism

Scientific Reports, 2018
Transfer of nitrogen fixation ability to plants, especially crops, is a promising approach to mitigate dependence on chemical nitrogen fertilizer and alleviate environmental pollution caused by nitrogen fertilizer run-off. However, the need to transfer a

Coinoculation of Bradyrhizobium and Azospirillum to Mitigate the Effects of Drought Stress in Soybean Plants

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Bacteria of the genus Azospirillum have been used to mitigate negative effects of drought stress. Since there is few information on interaction of new strains of A. brasilense and soil water status, we evaluated the effects of coinoculation of A. brasilense strains (Ab‐V5/Ab‐V6 and HM053) on soybean plants grown either with (40% of field capacity) or ...

A Non‐Covalent [4Fe–4S]/[2Fe] Interface in HydF Guides [FeFe]‐Hydrogenase Maturation

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Bridged or not? 57Fe NRVS reveals a non‐covalent, electronically coupled interaction between the HydF [4Fe–4S] cluster and the [2Fe] precursor. Boltz‐2 structure predictions suggest that the cubane organizes lipoate‐dependent Hmet chemistry, positioning intermediates for assembly of the CH2–NH–CH2 bridge during H‐cluster biosynthesis.
