Nitrogen Status Rewires Transcriptional Regulation of Dhurrin, a Dual-Purpose Defense Metabolite in <i>Sorghum bicolor</i>. [PDF]
ABSTRACT Dhurrin, a cyanogenic glucoside, plays an important role in Sorghum bicolor physiology and defense. The concentration of dhurrin in sorghum is influenced by both nitrogen status and stage of plant organ development. While nitrogen resupply activates the expression of genes for dhurrin biosynthesis, the molecular mechanisms underlying this ...

A supercritical fluid workflow for the quality assessment of herbal drugs and commercial preparations from Rhodiola rosea. [PDF]
Abstract Introduction Preparations from the Rhodiola rosea are experiencing an increase in popularity: extracts of dried roots and rhizomes are used as adaptogen to treat stress, fatigue, and weakness. To meet high pharmaceutical standards, fast and reliable methods to assess phytochemical variations in respect of quality control are needed.

Subcellular Mechanisms of Se(IV) Reduction in Stenotrophomonas bentonitica: Linking Environmental Detoxification and Antimicrobial Activity of Se Nanostructures Within a Circular Economy Framework. [PDF]
Stenotrophomonas bentonitica reduces Se(IV) via compartment‐specific pathways in the cytoplasm and membrane, yielding amorphous SeNPs coated with a protein‐rich organic corona. Biogenic SeNPs trigger strain‐specific toxicity: ROS‐mediated oxidative and genotoxic stress in Escherichia coli, and early membrane disruption in Staphylococcus aureus ...

Abstract The Chinese pangolin is a critically endangered and biologically unique species, yet information on its status, distribution, and habitat preferences is still scarce in Nepal, which limits effective conservation action. This study identified the current burrow density status, distribution pattern, and important habitat parameters associated ...

In a tree diversity experiment where different mycorrhizal host species were planted in monospecific stands and in mixtures, we found that combining arbuscular or ectotrophic mycorrhizae affect mycorrhization rates and richness of AM and EM fungi. Glomeromycota richness was larger in monotypic AM tree combinations than in mixtures of AM‐EM host trees ...

Tree Species Vulnerability to Fire Increases at Dry Range Edge
Following severe drought and fire, some tree species experience increased tree mortality, topkill (death of above‐ground biomass) and lower rates of seedling recruitment at the dry edge of their ranges, while other species maintain resilience, exhibiting low rates of mortality and topkill and high rates of recruitment across their ranges.

Co‐inoculation with Bacillus and Cp2‐Exopolysaccharides (EPS) promotes salt stress tolerance and productivity in alfalfa. CK1 (control1): distilled water, DN2: Bacillus strain DN2, EPS: Exopolysaccharide, CK2 (control2): 100 mmol·L‐1 NaCl, S: Salt. Abstract Background Alfalfa is one of the most important forage crops in the world, and its performance ...

Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (

A macroecological perspective on strategic bat conservation in the U.S. National Park Service
Abstract North American bat populations face unprecedented threats from disease and rapid environmental change, requiring a commensurate strategic conservation response. Protected‐area networks have tremendous potential to support coordinated resource protection, disease surveillance, and population monitoring that could become a cornerstone of 21st ...
