Coordinated transcriptional regulation between a reactive oxygen species-responsive gene network and the circadian clock in Arabidopsis thaliana : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Plant Biology at Massey University, Plant Biology, New Zealand [PDF]

open access: yes, 2012
Most organisms have evolved endogenous biological clocks as internal timekeepers to fine-tune physiological processes to the external environment. Energetic cycles such as photosynthesis and glycolytic cycles are physiological processes that have ...

Inoculation response of mycorrhizas on morphology and physiological behaviour of trifoliate orange (Poncirus trifoliata) roots under salt stress

open access: yesThe Indian Journal of Agricultural Sciences, 2016
Citrus is highly sensitive to salt stress, and little efforts have been successful microbiologically to mitigate such abiotic stress. In this background, trifoliate orange [Poncirus trifoliata (L.) Raf.] seedlings were inoculated with Diversispora ...

Inhibition of chickpea seedling copper amine oxidases by tetraethylenepentamine [PDF]

open access: yes
Copper amine oxidases are important enzymes, which contribute to the regulation of monoand polyamine levels. Each monomer contains one Cu(II) ion and 2,4,5-trihydroxyphenylalanine (TPQ) as cofactors.

HPLC–UV assay for the evaluation of inhibitors of plasma amine oxidase using crude bovine plasma

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
Recently, we have described a method for evaluation of plasma amine oxidase (PAO) inhibitors, which monitors the formation of 6-(5-phenyl-2H-tetrazol-2-yl)hexanal from the corresponding amine substrate by HPLC with UV-detection using purified bovine PAO.

High-valent copper in biomimetic and biological oxidations [PDF]

open access: yes, 2016
A long-standing debate in the Cu-O2 field has revolved around the relevance of the Cu(III) oxidation state in biological redox processes. The proposal of Cu(III) in biology is generally challenged as no spectroscopic or structural evidence exists ...

Copurification of actin and desmin from chicken smooth muscle and their copolymerization in vitro to intermediate filaments [PDF]

open access: yes, 1979
Desmin is a 50,000-mol wt protein that is enriched along with 100-A filaments in chicken gizzard that has been extracted with 1 M KI. Although 1 M KI removes most of the actin from gizzard, a small fraction of this protein remains persistently insoluble,

Development of a Capacitance-Based Biosensor for the Determination of Histamine Concentration [PDF]

open access: yes, 2009
Histamine level has been suggested as a rapid fish spoilage indicator. Besides that, a biosensor device with low cost, simple and portable is an advantage for fish freshness monitoring.

Effects of Exogenous Sugar Treatment on Enrichment of γ-Aminobutyric Acid in Peanut Sprouts

open access: yesShipin gongye ke-ji
In order to explore the influence of sugar treatment on the enrichment of γ-aminobutyric acid (GABA) in peanut sprouts, this paper selected the optimal application concentration of different types of exogenous sugars (mannose, sucrose and glucose).
