Use of streptavidin bound to biotinylated DNA structures as model substrates for analysis of nucleoprotein complex disruption by helicases [PDF]

, 2016
Helicases are a subfamily of translocases that couple the directional translocation along a nucleic acid lattice to the separation of nucleic acid duplexes using the energy derived from nucleoside triphosphate hydrolysis.

Mycoflora in Exhumed Seeds of Opuntia tomentosa and Its Possible Role in Seed Germination

Applied and Environmental Soil Science, Volume 2011, Issue 1, 2011., 2011
The funicular cover of the Opuntia tomentosa seed limits imbibition; germination occurs only when the funicle is weakened or the funicular valve is removed. We investigated the role of fungi in funicular weakening and seed germination. Seeds that had been either buried in one of two sites or stored in the laboratory were germinated with and without a ...

Spatial Representativeness of MexFlux as a Regional FLUXNET Network

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Environmental observatory networks are fundamental in advancing scientific understanding of biogeochemical processes. FLUXNET is a global network of regional eddy covariance networks that measure ecosystem‐scale exchanges of greenhouse gases (e.g., CO2, CH4, H2O) and energy between the biosphere and the atmosphere.
