Hydrogen sulfide: Environmental factor or signalling molecule? (2013)
Journal Article

Hydrogen sulfide (H2S) has traditionally been thought of as a phytotoxin, having deleterious effects on the plant growth and survival. It is now recognized that plants have enzymes which generate H2S, cysteine desulfhydrase, and remove it, O-acetylse... Read More about Hydrogen sulfide: Environmental factor or signalling molecule?.

Low dose ionizing radiation produces too few reactive oxygen species to directly affect antioxidant concentrations in cells (2012)
Journal Article

It has been hypothesized that radiation-induced oxidative stress is the mechanism for a wide range of negative impacts on biota living in radioactively contaminated areas around Chernobyl. The present study tests this hypothesis mechanistically, for...

NO synthase? Generation of nitric oxide in plants (2012)
Journal Article

Differential redox potential between the human cytosolic and mitochondrial branched-chain aminotransferase (2012)
Journal Article

The human branched-chain aminotransferase (hBCAT) isoenzymes are CXXC motif redox sensitive homodimers central to glutamate metabolism in the central nervous system. These proteins respond differently to oxidation by H 2O 2, NO, and S-glutathionylati...

In planta conditions induce genomic changes in Pseudomonas syringae pv. phaseolicola (2011)
Journal Article

The co-evolution of bacterial plant pathogens and their hosts is a complex and dynamic process. Plant resistance can impose stress on invading pathogens that can lead to, and select for, beneficial changes in the bacterial genome. The Pseudomonas syr...

The relationship of proline content and metabolism on the productivity of maize plants (2011)
Journal Article

The free proline content in maize ear-leaves, silk and pollen were analyzed in field grown plants which had matured to the pollination stage. Using maize hybrids PR34F02, PR35P12 and PR36B08 field trials were set up at two locations in eastern croati...

Translationally controlled tumour protein (TCTP) is a novel glucose-regulated protein that is important for survival of pancreatic beta cells (2011)
Journal Article

Aims/hypothesis: This study used proteomics and biochemical approaches to identify novel glucose-regulated proteins and to unveil their role in pancreatic beta cell function. Translationally controlled tumour protein (TCTP) was identified to be one s...

Hydrogen sulfide and signaling in plants (2011)
Journal Article

Nitric oxide and ABA in the control of plant function (2011)
Journal Article

Abscisic acid (ABA) and nitric oxide (NO) are both extremely important signalling molecules employed by plants to control many aspects of physiology. ABA has been extensively studied in the mechanisms which control stomatal movement as well as in see... Read More about Nitric oxide and ABA in the control of plant function.

Hydrogen sulfide effects on stomatal apertures (2011)
Journal Article

A novel hydrogen sulfide donor causes stomatal opening and reduces nitric oxide accumulation (2010)
Journal Article

Effects of hydrogen sulfide (H2S) on plant physiology have been previously studied, but such studies have relied on the use of NaSH as a method for supplying H2S to tissues. Now new compounds which give a less severe H2S shock and a more prolonged ex... Read More about A novel hydrogen sulfide donor causes stomatal opening and reduces nitric oxide accumulation.

Assessment of the influence of different sample processing and cold storage duration on plant free proline content analyses (2010)
Journal Article

Introduction - A method which is widely accepted for the analysis of free proline content in plant tissues is based on the use of 3% sulfosalicylic acid as an extractant, followed by spectrophotometric quantification of a proline-ninhydrin complex in...

A proteomic analysis of oligo(dT)-bound mRNP containing oxidative stress-induced Arabidopsis thaliana RNA-binding proteins ATGRP7 and ATGRP8 (2010)
Journal Article

Plants are highly adapted to respond to a range of environmental stresses commonly by altering their gene expression and metabolism as a result of cell signalling which may be mediated by reactive oxygen species. The glycine-rich RNA-binding proteins... Read More about A proteomic analysis of oligo(dT)-bound mRNP containing oxidative stress-induced Arabidopsis thaliana RNA-binding proteins ATGRP7 and ATGRP8.

The role of redox mechanisms in cell signalling (2009)
Journal Article

Functioning and efficient cell signalling is vital for the survival of cells. Over the years various components have been identified and recognised as crucial for the transduction of signals in cells. Many of the mechanisms allow for a relatively rap...
