The hormonal responses differed between the clones; the O(3)-sensitive clone 51 had higher ET evolution than the tolerant clone 200 during the exposure, whereas the free salicylic acid concentration in clone 200 was higher than in clone 51. The cellular redox status, measured as glutathione redox balance, did not differ between the clones suggesting that the O(3) lesions were not a result of deficient antioxidative capacity. The buildup of salicylic acid during chronic O(3) exposure might have prevented the up-regulation of ET biosynthesis in clone 200. Blocking of ET perception with 1-methylcyclopropene protected both clones from the decrease in net photosynthesis during chronic exposure to O(3). After a pretreatment with low O(3) for 9 d, an acute 1.5-fold O(3) elevation caused necrosis in the O(3)-sensitive clone 51, which increased substantially when ET perception was blocked. The results suggest that in hybrid aspen, ET signaling had a dual role depending on the severity of the stress. ET accelerated leaf senescence under low O(3), but under acute O(3) elevation, ET signaling seemed to be required for protection from necrotic cell death."],["dc.identifier.doi","10.1104/pp.102.018630"],["dc.identifier.pmid","12746525"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7451"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15145"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Differential Effects of Elevated Ozone on Two Hybrid Aspen Genotypes Predisposed to Chronic Ozone Fumigation.

Based on their chemical and physical properties three different molecular mechanisms of heavy metal toxicity can be distinguished: (a) production of reactive oxygen species by autoxidation and Fenton reaction; this reaction is typical for transition metals such as iron or copper, (b) blocking of essential functional groups in biomolecules, this reaction has mainly been reported for non-redox-reactive heavy metals such as cadmium and mercury, (c) displacement of essential metal ions from biomolecules; the latter reaction occurs with different kinds of heavy metals. Transition metals cause oxidative injury in plant tissue, but a literature survey did not provide evidence that this stress could be alleviated by increased levels of antioxidative systems. The reason may be that transition metals initiate hydroxyl radical production, which can not be controlled by antioxidants. Exposure of plants to non-redox reactive metals also resulted in oxidative stress as indicated by lipid peroxidation, H2O2 accumulation, and an oxidative burst. Cadmium and some other metals caused a transient depletion of GSH and an inhibition of antioxidative enzymes, especially of glutathione reductase. Assessment of antioxidative capacities by metabolic modelling suggested that the reported diminution of antioxidants was sufficient to cause H2O2 accumulation. The depletion of GSH is apparently a critical step in cadmium sensitivity since plants with improved capacities for GSH synthesis displayed higher Cd tolerance. Available data suggest that cadmium, when not detoxified rapidly enough, may trigger, via the disturbance of the redox control of the cell, a sequence of reactions leading to growth inhibition, stimulation of secondary metabolism, lignification, and finally cell death. This view is in contrast to the idea that cadmium results in unspecific necrosis. Plants in certain mycorrhizal associations are less sensitive to cadmium stress than non-mycorrhizal plants. Data about antioxidative systems in mycorrhizal fungi in pure culture and in symbiosis are scarce. The present results indicate that mycorrhization stimulated the phenolic defence system in the Paxillus-Pinus mycorrhizal symbiosis. Cadmium-induced changes in mycorrhizal roots were absent or smaller than those in non-mycorrhizal roots. These observations suggest that although changes in rhizospheric conditions were perceived by the root part of the symbiosis, the typical Cd-induced stress responses of phenolics were buffered. It is not known whether mycorrhization protected roots from Cd-induced injury by preventing access of cadmium to sensitive extra- or intracellular sites, or by excreted or intrinsic metal-chelators, or by other defence systems. It is possible that mycorrhizal fungi provide protection via GSH since higher concentrations of this thiol were found in pure cultures of the fungi than in bare roots. The development of stress-tolerant plant-mycorrhizal associations may be a promising new strategy for phytoremediation and soil amelioration measures."],["dc.identifier.doi","10.1093/jexbot/53.372.1351"],["dc.identifier.isi","000175693600012"],["dc.identifier.pmid","11997381"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/43832"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Oxford Univ Press"],["dc.publisher.place","Oxford"],["dc.relation.conference","Annual Meeting of the Society-for-Experimental-Biology"],["dc.relation.eissn","1460-2431"],["dc.relation.eissn","0022-0957"],["dc.relation.eventlocation","UNIV KENT, CANTERBURY, ENGLAND"],["dc.relation.issn","1460-2431"],["dc.relation.issn","0022-0957"],["dc.title","Plant responses to abiotic stresses: heavy metal-induced oxidative stress and protection by mycorrhization"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

How do plants perceive heavy metals and which signalling cascades are triggered leading to plant adaptation or injury? Copper (Cu) and cadmium (Cd) are reviewed as examples for heavy metals with contrasting physicochemical properties and functions in plants. Cu is an essential ligand for the catalytic activity of many enzymes. Its uptake and trafficking are tightly regulated and mediated by specific transporters and chaperones. Cu serves as a signalling intermediate for ethylene reception. Excess Cu is sensed by binding to transcription factors, thereby, activating an arsenal of abiotic stress defences including increased expression of metallothioneins, phytochelatins, and antioxidants which contribute to remove “free” Cu and to re-establish cellular ion and redox homeostasis. In contrast to Cu, no specific uptake systems are known for Cd. Cd enters cells by metal transporters with broad substrate specificities and probably also via Ca channels. It is toxic because of its high reactivity with sulphhydryl groups and causes oxidative stress by depletion of antioxidative systems and stimulation of H2O2-producing enzymes. As a result, Cd triggers stress signalling pathways similar to those activated by Cu including cascades leading to programmed cell death. Important cross-talk exists between heavy metal and other abiotic stress signalling pathways (drought, oxidative stress). Excess heavy metals affect root functions at multiple levels and cause accumulation of abscisic acid (ABA). We propose a model how ABA and Cd signalling may interact at the organismic level to influence plant water status. Cytokinins act as antagonists of Cd indicating that the plant internal hormonal status may critically affect heavy metal tolerance."],["dc.identifier.doi","10.1007/978-3-540-39402-0_8"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/56833"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.publisher","Springer"],["dc.publisher.place","Berlin, Heidelberg"],["dc.relation.crisseries","Topics in Current Genetics"],["dc.relation.isbn","978-3-540-20037-6"],["dc.relation.isbn","978-3-540-39402-0"],["dc.relation.ispartof","Plant Responses to Abiotic Stress"],["dc.relation.ispartofseries","Topics in Current Genetics; 4"],["dc.title","Heavy metal signalling in plants: linking cellular and organismic responses"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Cd (50 microM, 6 h) initially increased superoxide dismutase, inhibited the systems involved in H(2)O(2) removal (glutathione/glutathione reductase, catalase [CAT], and ascorbate peroxidase [APX]), and caused H(2)O(2) accumulation. Elongation of the roots was completely inhibited within 12 h. After 24 h, glutathione reductase activities recovered to control levels; APX and CAT were stimulated by factors of 5.5 and 1.5. Cell death was increased. After 48 h, nonspecific peroxidases and lignification were increased, and APX and CAT activities were decreased. Histochemical analysis showed that soluble phenolics accumulated in the cytosol of Cd-treated roots but lignification was confined to newly formed protoxylem elements, which were found in the region of the root tip that normally constitutes the elongation zone. Roots exposed to 5 microM Cd showed less pronounced responses and only a small decrease in the elongation rate. These results suggest that in cells challenged by Cd at concentrations exceeding the detoxification capacity, H(2)O(2) accumulated because of an imbalance of redox systems.
