Frontiers in Plant Science, 2016 Leaf senescence is a typical symptom in plants exposed to dark and may be regulated by plant growth regulators. The objective of this study was to determine whether exogenous application of melatonin (N-acetyl-5-methoxytryptamine) suppresses dark-induced

The invertebrate Caenorhabditis elegans biosynthesizes ascorbate. [PDF]
, 2015 l-Ascorbate, commonly known as vitamin C, serves as an antioxidant and cofactor essential for many biological processes. Distinct ascorbate biosynthetic pathways have been established for animals and plants, but little is known about the presence or ...

Molecular Cloning and Functional Expression of Rat Liver Glutathione-dependent Dehydroascorbate Reductase [PDF]
Journal of Biological Chemistry, 1998 We have isolated a cDNA clone for a novel glutathione-dependent dehydroascorbate reductase from a rat liver cDNA library in lambdagt11 by immunoscreening. The authenticity of the clone was confirmed as follows: first, the antibody that had been purified through affinity for the protein expressed by the cloned lambdagt11 phage recognized only the enzyme

Meta‐Analysis of Iron Excess Stress in Rice: Genes and Mechanisms of Tolerance to Acidic Soil
Physiologia Plantarum, Volume 177, Issue 5, September/October 2025.ABSTRACT Iron toxicity, predominantly stemming from excessive levels of ferrous iron (Fe2+) in acidic soils, poses a considerable challenge for crop production. Hypoxic conditions induced by waterlogging can exacerbate Fe2+ availability, which significantly impacts the cultivation and productivity of rice (Oryza sativa), a staple food for millions ...

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]
, 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 ...

American Journal of Botany, Volume 112, Issue 8, August 2025.Abstract Premise Soil salinization is a growing global challenge that significantly reduces agricultural productivity by impairing seed germination, growth, and yield. While conventional crops have limited tolerance to high salinity, halophytes are promising biological models for developing strategies to sustain agriculture in saline environments and ...
