Efficacy of Put and Spd sprayed on leaves from Brassica juncea plants against Cd2+-induced oxidative stress

چکیده
16 17 The protective effect exerted by polyamines (Put and Spd) against cadmium (Cd) 18 stress was investigated in Brassica juncea plants. Treatment with CdCl2 (75 μM) 19 resulted in a rise of Cd accumulation, a decrease of fresh and dry weights in every 20 plant organ, an increase of free polyamine content at limb and stem levels as well as a 21 decrease at root level. On the other hand, the total conjugated polyamine levels in the stem 22 tissues were unaffected by Cd. In the leaf tissues, this metal caused a reduction of chlorophyll 23 a content, a rise of guaiacol peroxidase (GPOX) activity and an increase of malondialdehyde 24 (MDA), soluble glucide, proline and amino acid contents. 25 Manuscript Click here to view linked References

Alleviation of oxidative stress induced by drought stress through priming by β-aminobutyric acid (BABA) in Rapeseed (Brassica napus L.) plants. Neda Mohamadi1,2, Amin Baghizadeh3*, Sara Saadatmand1, Zahra Asrar4
The objective of this study was to investigate the role of β-aminobutyric acid(BABA) (0, 300µM) in reduction of oxidative damages in leaves and roots of Brassica napus L. under drought stress (0, -0.2, -0.4 MPa). β-aminobutyric acid was investigated as an internal regulator hormone and its role in defense mechanisms against biotic and abioticstresses. In this study, BABA pretreatment prevented...
متن کاملCadmium-induced accumulation of putrescine in oat and bean leaves.
The effects of Cd2+ on putrescine (Put), spermidine (Spd), and spermine (Spm) titers were studied in oat and bean leaves. Treatment with Cd2+ for up to 16 hours in the light or dark resulted in a large increase in Put titer, but had little or no effect on Spd or Spm. The activity of arginine decarboxylase (ADC) followed the pattern of Put accumulation, and experiments with alpha-difluoromethy...
متن کاملPhytotoxicity and oxidative stress perspective of two selected nanoparticles in Brassica juncea
This study elaborates the consequences of oxidative stress caused by copper oxide (CuO) and titanium dioxide (TiO2) nanoparticles (NPs) in Brassica juncea. Effect of these two NPs on plant physiology, reactive oxygen scavenging enzyme system (ascorbate peroxidase, catalase, superoxide dismutase), proline content and lipid peroxidation has been estimated in leaves as well as root tissues. Bioacc...
متن کاملOverexpression of gamma-tocopherol methyl transferase gene in transgenic Brassica juncea plants alleviates abiotic stress: physiological and chlorophyll a fluorescence measurements.
Tocopherols (vitamin E) are lipid soluble antioxidants synthesized by plants and some cyanobacteria. We have earlier reported that overexpression of the gamma-tocopherol methyl transferase (gamma-TMT) gene from Arabidopsis thaliana in transgenic Brassica juncea plants resulted in an over six-fold increase in the level of alpha-tocopherol, the most active form of all the tocopherols. Tocopherol ...
متن کاملRegulation of Cadmium-Induced Proteomic and Metabolic Changes by 5-Aminolevulinic Acid in Leaves of Brassica napus L.
It is evident from previous reports that 5-aminolevulinic acid (ALA), like other known plant growth regulators, is effective in countering the injurious effects of heavy metal-stress in oilseed rape (Brassica napus L.). The present study was carried out to explore the capability of ALA to improve cadmium (Cd2+) tolerance in B. napus through physiological, molecular, and proteomic analytical app...
