Nitrogen Status Rewires Transcriptional Regulation of Dhurrin, a Dual-Purpose Defense Metabolite in <i>Sorghum bicolor</i>. [PDF]

open access: yesPlant Direct
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]

open access: yesPhytochem Anal, 2021
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]

open access: yesMicrob Biotechnol
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 ...

Factors affecting the occupancy of Chinese pangolins (Manis pentadactyla) suggest a highly specialized ecological niche

open access: yesEcosphere, Volume 14, Issue 1, January 2023., 2023
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 ...

Mixing tree species associated with arbuscular or ectotrophic mycorrhizae reveals dual mycorrhization and interactive effects on the fungal partners

open access: yesEcology and Evolution, Volume 11, Issue 10, Page 5424-5440, May 2021., 2021
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 ...

Variation in IgE binding potencies of seven Artemisia species depending on content of major allergens

open access: yesClinical and Translational Allergy, Volume 10, Issue 1, 2020., 2020
Abstract Background Artemisia weed pollen allergy is important in the northern hemisphere. While over 350 species of this genus have been recorded, there has been no full investigation into whether different species may affect the allergen diagnosis and treatment.

Tree Species Vulnerability to Fire Increases at Dry Range Edge

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
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 exopolysaccharide Cp2‐exopolysaccharides promotes salt stress tolerance and productivity in alfalfa

open access: yesGrassland Research, Volume 5, Issue 2, Page 119-131, June 2026.
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 ...

Renewed coexistence as a conceptual reframing of animal reintroductions to foster sustainable human–wildlife coexistence

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
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

open access: yesEcosphere, Volume 7, Issue 11, November 2016., 2016
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 ...
