    Landscape diversity promotes landscape functioning in North America by Sarah Mayor, Florian Altermatt, Thomas W. Crowther, Iris Hordijk, Simon Landauer, Jacqueline Oehri, Merin Reji Chacko, Michael E. Schaepman, Bernhard Schmid, Pascal A. Niklaus

    Published 2025-01-01
    “…However, it remains unclear whether these findings apply in real-world landscapes that resemble a heterogeneous mosaic of different ecosystem and plant types that interact through biotic and abiotic processes. Here, we show that landscape-level diversity, measured as number of land-cover types (different ecosystems) per 250×250 m, is positively related to landscape-wide remotely-sensed primary production across all of North America, covering 16 of 18 ecoregions of Earth. …”

    Nano-selenium strengthens potato resistance to potato scab induced by Streptomyces spp., increases yield, and elevates tuber quality by influencing rhizosphere microbiomes by Haixu Liu, Yan Zhang, Lili Zhang, Yingjie Liu, Yufei Chen, Ying Shi

    Published 2025-02-01
    “…IntroductionThe application of selenium could directly or indirectly modulate the activity of antioxidant enzymes in crops, thereby mitigating the detrimental effects of abiotic and biotic stresses on crop health. However, there are few studies on the effects of nano-selenium fertilizer on potato scab caused by Streptomyces spp., potato yield and tuber quality.MethodsWe aimed to elucidate the impact of nano-selenium fertilizer on potato disease resistance, yield, tuber quality, antioxidant enzyme activity and rhizosphere soil bacterial communities, and to determine the optimal frequency and growth stages of nano-selenium fertilizer spraying.Results and discussionThe application of nano-selenium fertilizer twice during the seedling stage significantly reduced the disease index of potato scab, enhanced potato yield, tuber quality (dry matter, Vitamin C, crude protein, and selenium content), and antioxidant enzyme activity (glutathione peroxidase, peroxidase, polyphenol oxidase, superoxide dismutase, and phenylalanine ammonia lyase). …”

    Development and some applications of enzyme-linked immunosorbent assay system for murine macrophage inflammatory protein-2 (MIP-2) by H. Ochiai, S. Sakai, T. Kogure, T. Hirabaytashi, K. Nakajima, K. Terasawa

    Published 1996-01-01
    “…The specificity of antibody was confirmed by Western blotting analysis of 20-h conditioned medium from lipopolysaccharide (LPS)-stimulated RAW264.7 cells, a murine macrophage cell line; antibody gave a single band with a molecular weight of approximately 6000, which is identical to that of murine MIP-2 reported previously. Biotin–streptavidin sandwich ELISA could detect quantitatively MIP-2 at concentration range of 20 to 1000 pg/ml. …”

    Microarrays as Model Biosensor Platforms to Investigate the Structure and Affinity of Aptamers by Jennifer A. Martin, Yaroslav Chushak, Jorge L. Chávez, Joshua A. Hagen, Nancy Kelley-Loughnane

    Published 2016-01-01
    “…An indirect labeling method, where the target was labeled with a biotin followed by a brief Cy3-streptavidin incubation, provided a higher signal-to-noise ratio and over two orders of magnitude improvement in limit of detection, compared to direct Cy3-protein labeling. …”

    RNase P cleavage of pseudoknot substrates reveals differences in active site architecture that depend on residue N-1 in the 5’ leader by David M. Kosek, J. Luis Leal, Ema Kikovska-Stojanovska, Guanzhong Mao, Shiying Wu, Samuel C. Flores, Leif A. Kirsebom

    Published 2025-12-01
    “…We show that a small biotin-binding RNA aptamer that folds into a pseudoknot structure acts as a substrate for bacterial RNase P RNA (RPR) with and without the RNase P C5 protein. …”

    Commercial bioinoculants improve colonization but do not alter the arbuscular mycorrhizal fungal community of greenhouse-grown grapevine roots by Mariam P. Berdeja, Nicole K. Reynolds, Teresa Pawlowska, Justine E. Vanden Heuvel

    Published 2025-01-01
    “…Abstract Background Arbuscular mycorrhizal fungi (AMF) are beneficial root symbionts contributing to improved plant growth and development and resistance to abiotic and biotic stresses. Commercial bioinoculants containing AMF are widely considered as an alternative to agrochemicals in vineyards. …”

    Population persistence, phenotypic divergence, and metabolic adaptation in yarrow (Achillea millefolium L.) by Gianalberto Losapio, Baptiste Doussot, Fabrizio Araniti, Leonardo Bruno, Roger Guevara, Rodolfo Dirzo

    Published 2024-12-01
    “…These findings suggest that ongoing adaptation is constrained by long‐term changes in temperature and precipitation as well as by local biotic interactions. Preserving locally adapted populations and their metabolic diversity is key for conservation efforts in the face of accelerating climate change.…”
