Synergistic action of silicon nanoparticles and indole acetic acid in alleviation of chromium (Cr) toxicity in Oryza sativa seedlings.

The present study investigates ameliorative effect of silicon nanoparticles (SiNPs) and indole acetic acid (IAA) alone and in combination against hexavalent chromium (Cr) toxicity in rice seedlings. The results of the study revealed protective effects of SiNPs and IAA against Cr toxicity. The 100 μM of Cr imposed toxic effects in rice seedlings at morphological, physiological and biochemical levels which coincided with increased level of intracellular Cr and declined level of endogenous nitric oxide (NO).

Silicon and nitric oxide interplay alleviates copper induced toxicity in mung bean seedlings.

The present study was aimed to investigate copper (Cu) toxicity alleviatory potential of silicon in Vigna radiata L. (mung bean) seedlings. Moreover, attention has also been paid to find out whether endogenous nitric oxide (NO) has any role in Si-governed alleviation of Cu stress.

Aluminum toxicity and aluminum stress-induced physiological tolerance responses in higher plants.

Aluminum (Al) precipitates in acidic soils having a pH < 5.5, in the form of conjugated organic and inorganic ions. Al-containing minerals solubilized in the soil solution cause several negative impacts in plants when taken up along with other nutrients.

Silicon tackles butachlor toxicity in rice seedlings by regulating anatomical characteristics, ascorbate-glutathione cycle, proline metabolism and levels of nutrients.

Reckless use of herbicides like butachlor (Buta) in the fields represents a serious threat to crop plants, and hence to their productivity. Silicon (Si) is well known for its implication in the alleviation of the effects of abiotic stresses; however, its role in mitigating Buta toxicity is not yet known. Therefore, this study was carried out to explore the role of Si (10 µM) in regulating Buta (4 µM) toxicity in rice seedlings.

Are the biopositive effects of X-rays the only benefits of repetitive mammograms?

Breast cancer mortality rates fell between 1990 and 2000. When something positive occurs in medicine attempts are usually made to explain the observation or claim the credit. In this case, credit has been given to improvements in standard treatments and to increased use of mammography, each said to have made a contribution.
