Abstract

Increase in the atmospheric ozone concentration has been shown to affect plant growth in several ways; from decreased photosynthetic activity to visible dames and in some extreme situations even to tissue death. Plants protect themselves from the damaging effect of ozone by inducing several physiological reactions. For example, increases in ethylene production, polyamine and phenylpropanoid synthesis have been observed in stress reaction induced by increased atmospheric ozone. similar changes, which are often called general stress reactions, are induced by several other biotic and which are often called general stress reactions, are induced by several other biontic and abiotic factors, e.g., plant pathogens. It has been shown previously that the production of stress ethylene can partly be responsible for the ozone damage formation in plants. Induction of stress-polyamine synthesis can prevent ethylene formation and is higher in some ozone-tolerant plants. We have exposed ozone sensitive and resistant birch clones to ozone (150 ppb. 8 hours) to analyze ozone-induced changes in the phenylpropanoid and polyamine metabolisms and gene expression. The polyamine and phenylpropanoid contents of the experimental material are currently being analyzed and the results will be presented. We have also cloned by PCR gene probes for birch ACC-synthase, arginine decarboxylase (ADC)more »« less

Ozone stress induces the expression of ACC synthase in potato plants

Conference Schlagnhaufer, C; Arteca, R; Pell, E - Plant Physiology; (United States)

When potato plants (Solanum tuberosum L. cv Norland) are subjected to oxone stress ethylene is emitted. Increases in ethylene production are often the result of increased expression of the enzyme ACC synthase. We used the polymerase chain reaction (PCR) to clone a cDNA encoding an ozone-induced ACC synthase. After treating potato plants with 300 ppb ozone for 4 h, RNA was extracted using a guanidinium isothiocyanate method. Using degenerate oligonucleotides corresponding to several conserved regions of ACC synthase sequences reported from different plant tissues as primers, we were able to reverse transcribe the RNA and amplify a cDNA for ACCmore »« less
Biochemical plant responses to ozone. 1. Differential induction of polyamine and ethylene biosynthesis in tobacco

Journal Article Langebartels, C; Kerner, K; Leonardi, S; ... - Plant Physiology; (United States)

Polyamine metabolism was examined in tobacco (Nicotiana tabacum L.) exposed to a single ozone treatment (5 or 7 hours) and then postcultivated in pollutant-free air. The levels of free and conjugated putrescine were rapidly increased in the ozone-tolerant cultivar Bel B and remained high for 3 days. This accumulation was preceded by a transient rise of L-arginine decarboxylase (ADC, EC 4.1.1.19) activity. The ozone-sensitive cultivar Bel W3 showed a rapid production of ethylene and high levels of 1-aminocyclopropane-1-carboxylic acid after 1 to 2 hours of exposure. Induction of putrescine levels and ADC activity was weak in this cultivar and wasmore »« less

Effect of ozone on indicators of leaf aging. [Solanum tuberosum]

Conference Ni, Yisheng; Dai, Yaoren; Negm, Fayek; ... - Plant Physiology, Supplement; (United States)

Ozone (O{sub 3}) stress induces accelerated foliar senescence, as measured by a decline in ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco). The authors wish to determine (1) whether the decline in rubisco is under genetic regulation and (2) what role is played by ethylene and polyamines in modulating this response. Plants of Solanum tuberosum L. cv. Norland were grown in a charcoal filtered greenhouse and treated with 0.15 {mu}1 1{sup {minus}1} O{sub 3} in continuous stirred tank reactors for 4 h. Immediately, 4 h and 20 h after O{sub 3} exposure, the fourth, seventh and tenth leaves from the apex were harvested and themore »« less
A genomics investigation of partitioning into and among flavonoid-derived condensed tannins for carbon sequestration in Populus

Technical Report Tsai, Chung-jui

The project set out to use comparative (genotype and treatment) and transgenic approaches to investigate the determinants of condensed tannin (CT) accrual and chemical variability in Populus. CT type and amount are thought to effect the decomposition of plant detritus in the soil, and thereby the sequestering of carbon in the soil. The stated objectives were: 1. Genome-wide transcriptome profiling (microarrays) to analyze structural gene, transcription factor and metabolite control of CT partitioning; 2. Transcriptomic (microarray) and chemical analysis of ontogenetic effects on CT and PG partitioning; and 3. Transgenic manipulation of flavonoid biosynthetic pathway genes to modify the controlmore »« less

Influence of vitamin E on polyamine metabolism in ozone-exposed rat lungs

Journal Article Elsayed, N - Arch. Biochem. Biophys.; (United States)

The influence of vitamin E (E) on lung polyamine metabolism of rats exposed to ozone (O/sub 3/) was examined. Rats fed diets either E-deficient or supplemented with 1000 IU E/kg were exposed to 0.5 +/- 0.05 ppm O/sub 3/ or filtered room air continuously for 5 days. They were then sacrificed and their lungs were analyzed for biochemical changes. Lung E content was strongly associated with the dietary level, and increased (36%, P less than 0.05) after O/sub 3/ exposure only in E-supplemented rats. Lung polyamine metabolism was not affected in the air-control rats by E level, but increased aftermore »« less
