Effect of Cyanobacteria Isolates on Rice Seeds Germination in Saline Soil

مجلة بغداد للعلوم, 2018
Cyanobacteria are prokaryotic photosynthetic communities which are used in biofertilization of many plants especially rice plant. Cyanobacteria play a vital role to increase the plant's ability for salinity tolerance.

Synergistic influence of deficit irrigation and Nostoc algae extract on wheat growth and water productivity in a sandy calcareous soil

Circular Agricultural Systems
Water scarcity and the rising cost of chemical fertilizers pose major challenges to sustainable crop production in Egypt, particularly in sandy soils with low fertility.

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

Anabaenopeptins from Nostoc edaphicum CCNP1411

International Journal of Environmental Research and Public Health, 2022
Cyanobacteria of the Nostoc genus belong to the most prolific sources of bioactive metabolites. In our previous study on Nostoc edaphicum strain CCNP1411, the occurrence of cyanopeptolins and nostocyclopeptides was documented. In the current work, the production of anabaenopeptins (APs) by the strain was studied using genetic and chemical methods ...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Molecular and phylogenetic characterization of two species of the genus Nostoc (Cyanobacteria) based on the cpcB-IGS-cpcA locus of the phycocyanin operon [PDF]

Journal of BioScience and Biotechnology, 2012
Traditionally, the taxonomy of the genus Nostoc is based on morphological and physiological characters. The extreme morphological variability of the Nostoc species, due to their life cycle and environmental conditions, hampers the correct identification ...

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Enabling Sustainability in Local Food Supply Chains: A Life Cycle Assessment‐Based Approach

Sustainable Development, EarlyView.
ABSTRACT In response to escalating environmental and food security challenges, this study explores how Local Food Systems (LFS) and Short Food Supply Chains (SFSCs) can be redesigned to support sustainability goals. Drawing on a case study of a microalgae‐based food producer, the research applies a Resource Nexus Approach combined with Life Cycle ...

Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

Journal of Phycology, EarlyView.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of
