14. Mitochondria.
From a quantitative viewpoint, in most cell types, mitochondria
are thought to be the largest contributors to intracellular oxidant
production.
Mitochondria generate ATP in an oxygen-dependent manner,
during which the flow of electrons down the respiratory chain
eventually culminates at complex IV with the reduction of
molecular oxygen to water.
Throughout this process, molecular oxygen can also undergo a
one-electron reduction to generate a superoxide anion.
15. 2014 ROS … NATURE REVIEWS | MOLECULAR CELL BIOLOGY VOLUME 15 |
JUNE 2014 |
The concept that oxidants can function as part of signal transduction pathways is a fairly new idea that has gained credence in the past two
decades (2,3). Both superoxide and hydrogen peroxide have been implicated as potential messengers, although the greater stability of
hydrogen peroxide seems to make it better equipped to function as a signalling intermediate. Given the chemical simplicity of most
ROS, the basis of how redox signalling achieves any measure of specificity has been difficult to understand. Recent evidence that
oxidants and their targets might be spatially confined within the cell could provide at least part of the answer (4). Although many
questions remain, ever growing numbers of observations regarding ROS biology are rapidly shaping our understanding of a range of
topics, including metabolic regulation, innate immunity, stem cell biology, the pathogenesis of cancer, and why and how
we age….
Finally, although mitochondrial oxidants have been historically viewed as purely toxic in nature, as discussed here they can also regulate
important intracellular signalling pathways (9–11)…
… a condition that is characterized by recurrent bacterial and fungal infections
Other enzymes. Mitochondria and the NOX family of enzymes are the best-characterized intracellular sources of ROS, but a wide range of
enzymes, such as xanthine oxidase, nitric oxide synthase, cyclooxygenases, cytochrome P450 enzymes and lipoxygenases, can all
produce ROS …This view has changed as a result of the growing appreciation that ROS reversibly modulate several important
intracellular pathways.
… reversible oxidation and reduction of other amino acids can occur, and emerging evidence indicates that Met residues, the other sulphur-
containing amino acid, might provide an analogous redox-dependent system (34)
… Interestingly, this general mechanism seems to be a conserved strategy for inducing a coordinated transcriptional response to a
rise in ROS levels.
… Thus, in this setting, oxidants seem both to mediate a direct host defence response and to have an important signalling function. A
similar, dual role for ROS is also evident in lower organisms(49).
… The hypothesis that ROS levels need to be tightly controlled is supported by studies of embryonic stem cells in which both
increasing and decreasing ROS levels can lead to genomic instability(71).
… Finally, another potential pathway whereby ROS might modulate stem cell fate comes from the emerging link between oxidants
and epigenetics. The first clear connection between ROS and chromatin modification has resulted from elegant studies in model
organisms such as yeast(78).

ROS and ageing
There is a long, historic association between ROS and ageing, which started more than 50 years ago with the studies of
Denham Harman, who initially proposed the free radical theory of ageing1. Since the initial formulation of this theory,
several studies have lent support to the argument that oxidants have a central role in the ageing process, although an
equivalent number of studies have come to different conclusions (98).
…The confusion regarding the link between ROS and ageing has recently taken another interesting turn with data from model
organisms indicating that oxidants might have a beneficial role in regulating lifespan. This line of evidence relates to the
phenomenon of hormesis — the concept that a little stress protects the cell or organism from a subsequent larger stress.
…) in yeast(108). Whether this paradigm extends to higher organisms remains mostly untested. Nevertheless, a small clinical
study showed that the beneficial effects of physical exercise were eliminated in patients who were given antioxidant
supplements, which might have inhibited a ROS-dependent hormetic response (109).
…Summary:
The idea that ROS function purely in a harmful and direct manner has given way to a more nuanced view that these molecules
can specifically modulate various biologically relevant pathways. Similarly to the phosphorylation and
dephosphorylation of Ser and Thr residues, the oxidation and reduction of Cys and Met residues provide a mechanism to
rapidly and reversibly alter protein function (FIG. 6). Challenges remain, as considerable gaps in our knowledge persist.
…Finally, the precise role of ROS in disease remains mostly unknown. Do oxidants protect from or promote cancers? Does
the release of ROS cause or prevent ageing? Nonetheless, from a biological point of view, it is beginning to look as if
ROS are neither cellular heroes nor villains — but instead something that occupies that always entertaining,
captivating and fertile middle ground.
17. Comprehensive Transcriptional Analysis of the Oxidative Response in Yeast*□ S
Press,April17,2008,DOI10.1074/jbc.M800295200
The lack of parallelism between the evolution of the mRNA amount and transcription rate predicts changes in mRNA stability
during stress. Genes for ribosomal proteins and rRNA processing enzymes are abundant among those whose mRNAs are
predicted to destabilize. The number of genes whose mRNAs are predicted to stabilize is lower, although some protein
folding or proteasomal genes are among the latter
…This study indicates that the oxidative stress response in yeast cells is not only conditioned by gene transcription but also by
them RNA decay dynamics and that this complex response may be particularly relevant to explain the temporary down-
regulation of protein synthesis occurring during stress.
Introduction.
Cells react against environmental stresses through multiple responses that occur at transcriptional and post-transcriptional
levels to adapt them selves to the new conditions and counteract the possible macromolecular damage caused by the
stress situation. Most systematic studies on such responses focus on changes in mRNA amounts (mRNA amount or
concentration (i.e. amount per cell), indicated as RA)caused by the environmental stress, using the DNA array
technology.
…When applied to a nutritional shift from glucose to galactose, the GRO methodology showed that TR was t he main
determinant of RA, although some groups of genes were modulated at the mRNA decay level(4).
…A general correlation was also found between mRNA decay rates and the physiological function of the gene products(8).
However, the experimental conditions employed for switching off transcription in the above studies caused a stress
situation per se in yeast cells, which discards using a similar approach or analysing mRNA kinetics after an
experimentally induced stress(16).
… Results indicate that for some functional groups of genes, changes in mRNA decay rates play an important role in the
adaptation to oxidative stress.
….Genes belonging to ribosome biogenesis categories and organic acid transport are specially controlled by changes in their
mRNA stability. This is the first time that such a detailed analysis of mRNA stability has been done for a dynamic
situation in any organism.
18. JOURNAL OF BIOLOGICAL CHEMISTRY VOLUME283 • NUMBER26 •JUNE27,2008
.As expected (34), initial mRNA decay rates followed first-order kinetics, and half-lives were calculated from the slopes of the log curves.
From a half life value of 14.3 min during exponential growth, this increased to18.6min after 20min of applying the stress, to decrease
to7.6 min after 60 min in stress conditions.
…Members of clusters 19 and 20 experience a much higher and rapid increase in mRNA levels than in TR upon the oxidative stress, which
consequently predicts a temporary stabilization of mRNA
…Thus, the experimental work using the regulatable tet promoter system confirmed the prediction of a stress induced mRNA
destabilization. Correlation between Transcription Parameters and Gene Function—mRNA level profiles in response to environmental
stresses tend to correlate among functionally related genes (36,37).Thus, levels of mRNA for RP and for rRNA processing proteins
decrease upon oxidative stress (1).
… This increase preceded that of mRNA levels. TR for mostmRNAscodingfortheproteasomecorecomplexiscoordinatelyup-
regulatedimmediatelyaftertheonsetoftheoxidativestress,andthisisfollowedbylaterepression.This by itself can explain the delayed
parallel changes in mRNA levels. The coordinated behaviour of TR for core proteasome genes can be related to the role of the Rpn4
transcription factor as regulator of expression of most proteasome yeast genes (38).
DISCUSSION. This work, we have extended previous studies on the effect of oxidative stress on mRNA amounts at the whole
transcriptome level(1,2).
…In most of the 4757 genes (about 80% of the yeast genome) for which complete TR and RA data were obtained in this study, changes in
one or both parameters occurred during the oxidative stress response.
….We may conclude that the down-regulation in the expression of ribosome-related genes and the subsequent inhibition of protein synthesis
after an oxidative stress result from additive contributions of inhibition of transcription and increased decay rate of the respective
mRNAs. Most of the clusters from 8 to25 display an immediate induction of TR upon the oxidative stress.
….Induction of a number of pathways of amino acid biosynthesis as a response to the moderate stress conditions employed here may be an
adaptive strategy to prepare cells for protein synthesis recovery. Particularly relevant is the strong induction of the biosynthetic
pathway for sulfur amino acids observed in this study. Such induction has not been reported in other studies on oxidative stress
responses where a higher oxidant concentration was employed(1).
….Glutathione is the substrate for glutaredoxins, a group of thiol oxidoreductases participating in the oxidative stress response (42,
43). These, together with other oxidoreductases and additional enzymes detoxifying reactive oxygen species were induced in our
study.

Irrigation efficiency and water-policy implications for river basin resilience
C. A. Scott1, S. Vicuña2, I. Blanco-Gutiérrez3, F. Meza2, and C. Varela-Ortega3
Abstract. Rising demand for food, fiber, and biofuels drives expanding irrigation withdrawals from surface water and groundwater.
Irrigation efficiency and water savings have become watchwords in response to climate-induced hydrological variability, increasing
freshwater demand for other uses including ecosystem water needs, and low economic productivity of irrigation compared to most
other uses. We identify three classes of unintended consequences, presented here as paradoxes. Ever-tighter cycling of water has been
shown to increase resource use, an example of the efficiency paradox. In the absence of effective policy to constrain irrigated area
expansion using “saved water”, efficiency can aggravate scarcity, deteriorate resource quality, and impair river basin resilience through
loss of flexibility and redundancy. Water scarcity and salinity effects in the lower reaches of basins (symptomatic of the scale paradox)
may partly be offset over the short-term through groundwater pumping or increasing surface water storage capacity. However,
declining ecological flows and increasing salinity have important implications for riparian and estuarine ecosystems and for non-
irrigation human uses of water including urban supply and energy generation, examples of the sectoral paradox. This paper briefly
considers three regional contexts with broadly similar climatic and water-resource conditions – central Chile, southwestern US, and
south-central Spain – where irrigation efficiency directly influences basin resilience.
The comparison leads to more generic insights on water policy in relation to irrigation efficiency and emerging or overdue needs for
environmental protection.

for ribosomal proteins and rRNA processing enzymes are abundant
among those whose mRNAs are predicted to destabilize. The number of
genes whose mRNAs are predicted to stabilize is lower, although some
protein folding or protea somal genes are among the latter. We have
confirmed the mathematical predictions for several genes pertaining to
different clusters by experimentally determining mRNA decay rates using
