“…In plants, they have been classified but not deeply studied (Kerk et al, 2003). Indeed, an USP was found to be induced in rice under submergence and to be positively regulated by ethylene, suggesting a role in adaptation to this stress (Sauter et al, 2002).…”

Reactive Oxygen Species-Driven Transcription in Arabidopsis under Oxygen Deprivation

et al. 2012

Reactive oxygen species (ROS) play an important role as triggers of gene expression during biotic and abiotic stresses, among which is low oxygen (O 2 ). Previous studies have shown that ROS regulation under low O 2 is driven by a RHO-like GTPase that allows tight control of hydrogen peroxide (H 2 O 2 ) production. H 2 O 2 is thought to regulate the expression of heat shock proteins, in a mechanism that is common to both O 2 deprivation and to heat stress. In this work, we used publicly available Arabidopsis (Arabidopsis thaliana) microarray datasets related to ROS and O 2 deprivation to define transcriptome convergence pattern. Our results show that although Arabidopsis response to anoxic and hypoxic treatments share a common core of genes related to the anaerobic metabolism, they differ in terms of ROS-related gene response. We propose that H 2 O 2 production under O 2 deprivation is a trait present in a very early phase of anoxia, and that ROS are needed for the regulation of a set of genes belonging to the heat shock protein and ROS-mediated groups. This mechanism, likely not regulated via the N-end rule pathway for O 2 sensing, is probably mediated by a NADPH oxidase and it is involved in plant tolerance to the stress.

“…A universal stress protein (USP) was originally reported to be induced in response to growth arrest or DNA damage in bacteria (Nystrom and Neidhardt 1994;Gustavsson et al 2002). Then a gene, OsUsp1, which is induced by submergence as well as ethylene, was reported to be a member of the USP family (Sauter et al 2002). Hypothetical proteins included 15 diVerent clones isolated in this study.…”

“…In the case of anoxic Arabidopsis, more than 600 out of over 22,500 genes were predicted by Loreti et al (2005) to be induced. From rice, the most tolerant plant species to anoxia among major crops, many genes up-regulated by Xooding stress have been isolated by subtractive hybridization methods (Agarwal and Grover 2005;Qi et al 2005;Sauter et al 2002). Caturla et al (2002) used suppression subtractive hybridization to isolate genes enhanced by submergence in adventitious root primordial of Sesbania rostrata.…”

Pondweed (Potamogeton distinctus A. Benn.), a monocot aquatic plant species, has turions, which are overwintering buds forming underground as an asexual reproductive organ. Turions not only survive for more than one month but also elongate under strict anoxia, maintaining high-energy charge by activation of fermentation. We cloned 82 cDNA fragments of genes, that are up-regulated during anoxic growth of pondweed turions, by suppression subtractive hybridization. The transcript levels of 44 genes were confirmed to be higher under anoxia than those in air by both Northern blot analysis and a semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) method. A homology search for their nucleotide sequences revealed that some of them are highly homologous to known sequences of genes from other plants. They included alcohol dehydrogenase, pyruvate decarboxylase (PDC), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), vacuolar H(+)-translocating pyrophosphatase and a plasma membrane intrinsic protein. Time courses of transcript accumulation of some genes under anoxia were different from those in air. The activity of PDC increased under anoxic conditions but the activities of GAPDH and pyrophosphatase remained constant after anoxic treatment. Anoxically up-regulated genes are possibly involved in physiological events to control energy production, pH regulation and cell growth under anoxia. These results suggest that transcriptional regulation of these genes serves as an essential part of survival and growth of pondweed turions under anoxia.

“…Corresponding electronic northern data were in accordance with spot variation. In rice, it is supposed to play a role in ethylene-mediated stress adaptation (Sauter et al, 2002). Apart from antioxidant proteins, some proteins related to dehydration stress were overexpressed during ripening, suggesting an effect of environmental conditions in the greenhouse during fruit ripening.…”

Tomato (Solanum lycopersicum) is a model plant for studying fleshy fruit development. Several genetic and molecular approaches have been developed to increase our knowledge about the physiological basis of fruit growth, but very few data are yet available at the proteomic level. The main stages of fruit development were first determined through the dynamics of fruit diameter and pericarp cell number. Then, total proteins were extracted from pericarp tissue at six relevant developmental stages and separated by two-dimensional gel electrophoresis. Protein patterns were markedly different between stages.Proteins showing major variations were monitored. We identified 90 of 1,791 well-resolved spots either by matrix-assisted laser-desorption ionization time-of-flight peptide mass fingerprinting or liquid chromatography-mass spectrometry sequencing and expressed sequence tag database searching. Clustered correlation analysis results pointed out groups of proteins with similar expression profiles during fruit development. In young fruit, spots linked to amino acid metabolism or protein synthesis were mainly expressed during the cell division stage and down-regulated later. Some spots linked to cell division processes could be identified. During the cell expansion phase, spots linked to photosynthesis and proteins linked to cell wall formation transiently increased. In contrast, the major part of the spots related to C compounds and carbohydrate metabolism or oxidative processes were up-regulated during fruit development, showing an increase in spot intensity during development and maximal abundance in mature fruit. This was also the case for spots linked to stress responses and fruit senescence. We discuss protein variations, taking into account their potential role during fruit growth and comparing our results with already known variations at mRNA and metabolite-profiling levels.
