Rotenone Effects On Phtosynthesis

After 15 h of rotenonetriton x-100 treatment, we found an induction of both transcripts, (about 3- and 5-fold, respectively). Iib- intech universidad nacional de general san martn (unsam) chascoms, buenos aires, argentina centro de estudios fotosintéticos y bioqumicos (cefobi-conicet) universidad nacional de rosario rosario, argentina leaves with rotenone is presented. Rotenone had no or small effect on glycine oxidation, whereas the role of cyanide-resistant path increased in the presence of atp.

In this work, we present a simple and reproducible method for the addition of rotenone in (var. Moreover, rotenonetriton x-100 incubated leaves presented an inhibition of oxygen uptake. Lanes 1, 5 water, lane 2, 6 0.

Triton, c 40 m rotenone, d 40 m rotenone plus 0. Ci contains more than 30 nuclear and mitochondrial-encoded proteins, and genome coordination is required for full activity. The incubation of leaves in the presence of rotenone and triton x-100 showed decreased oxygen uptake and induction in the transcription of in summary, the present work describes a simple and reliable procedure for the introduction of rotenone, a specific complex i inhibitor, in leaves.

This process is catalyzed by 5 respiratory complexes located in the inner mitochondrial membrane. Calibration was achieved by a simple 2-point calibration between air (21 o ) and the injection or removal of a known volume of air from the chamber. However, the oxidation of nadh in plant mitochondria is only partially sensitive to rotenone.

Detached arabidopsis leaves (200 to 300 mg) were placed in the oxygen electrode chamber. Furthermore, it has been described that several genes participating in protein import to mitochondria, molecular chaperones and genes codifying proteins involved in respiratory chain assembly are highly expressed after treatment of however, some methodological problems remain to be solved when used rotenone directly on leaves instead of cell cultures. Plants were cultivated on soil in greenhouse conditions at 25c under fluorescent lamps (grolux, sylvania and cool white, philips) with an intensity of 150 mol.

Semi-quantitative rt-pcr analysis was performed on the amplification of products after 16, 20, 24, 28 and 30 pcr cycles. This is because the existence of additional nadh dehydrogenases involved in nadh oxidation in the plant organelle. Metabolism of glycine in isolated mitochondria and protoplasts was investigated in photosynthetic, etiolated (barley and pea leaves) and fat-storing (maize scutellum) tissues using methods of 1-(14)cglycine incorporation and counting of 14co2 evolved, oxymetric measurement of glycine oxidation and rapid fractionation of protoplasts incubated in photorespiratory conditions with consequent determination of atpadp ratios in different cell compartments. An aliquot (1 l) of the cdna obtained from rt reaction was used as template in pcr reactions with specific oligonucleotides. Oxygen consumption was measured at 25c using an air-tight chamber fitted with a clark type electrode (hansatech leaf disc electrode unit, hansatech, uk).

The nadhubiquinone oxidoreductase (called complex i, ci, ec 1. It has been reported that the inhibition of ci activity results in an increase of mitochondrial biogenesis. The use of knock out mutants or ci inhibitors is important to better understand the role or function of mitochondrial ci.

    Total rna was isolated from leaves from 6-week-old plants using the tri reagent. Metabolism of glycine in isolated mitochondria and protoplasts was investigated in photosynthetic, etiolated (barley and pea leaves) and fat-storing (maize scutellum) tissues using methods of 1-(14)cglycine incorporation and counting of 14co2 evolved, oxymetric measurement of glycine oxidation and rapid fractionation of protoplasts incubated in photorespiratory conditions with consequent determination of atpadp ratios in different cell compartments. The actin gene was used as internal control. Total rna was extracted from leaves and reversed transcribed using random hexamers and then amplified using specific primers (see methods section). Department of plant physiology and biochemistry, voronezh university, russia. These results are in good agreement with the induction of these 2 genes in cell cultures. This complex catalyzes the oxidation of nadh and the subsequent transfer of electrons to ubiquinone, coupled to proton transport across the inner mitochondrial membrane. This is because the existence of additional nadh dehydrogenases involved in nadh oxidation in the plant organelle.
