Abstract: The present study investigates ameliorative effect of silicon nanoparticles (SiNPs) and indole acetic acid (IAA) alone and in combination against hexavalent chromium (CrVI) toxicity in rice seedlings. The results of the study revealed protective effects of SiNPs and IAA against CrVI toxicity. The 100 μM of CrVI imposed toxic effects in rice seedlings at morphological, physiological and biochemical levels which coincided with increased level of intracellular CrVI and declined level of endogenous nitric oxide (NO). The CrVI enhanced levels of superoxide radicals (SOR) (59.51% and 50.1% in shoot and root, respectively) and H2O2 (19.5% and 23.69% in shoot and root, respectively). However, when SiNPs and IAA were applied to plants under CrVI stress, they enhanced tolerance and defence mechanisms as manifested in terms of increased biomass, endogenous NO, photosynthetic pigments, and antioxidants level. It was also noticed that CrVI arrested cell cycle at G2/M phase whereas growth was restored as compared to control when SiNPs and IAA were supplemented. Thus, the hypothesis that combined application of SiNPs and IAA will be effective in alleviating CrVI toxicity is validated from the results of this study. Moreover, in SiNPs and IAA-mediated mitigation of CrVI toxicity, endogenous NO has a positive role. The importance of the study will be that the combination of SiNPs and IAA can be utilized against heavy metal stress and even when supplied alone, they will enhance the crop productivity parameters with and without stress conditions.

TL;DR: The effects of COVID-19 not only causes negative impact on social, economic, educational but also in every sphere of human life such as faith, religion, etc as mentioned in this paper.
Abstract: Corona virus disease (COVID-19) is one of the largest pandemics that the world is experiencing now. The disease has infected about 52.44 million people out of which about 1.29 million people have died as on 12th November 2020 and still the counting is on. Although around 36.67 million people have recovered from the disease, still all 220 countries, areas or territories with active cases are under the grip of the deadly Corona virus. Lockdowns and shutdowns are two socials move considered as the available preventive measures against COVID-19. The measure effects of COVID-19 not only causes the negative impact on social, economic, educational but also in every sphere of human life such as faith, religion, etc. The disease has imparted its tremendous effects on many functional and structural aspects in sectors such as social, educational, economical and religions level. Irrespective of the geographic location or richness, COVID-19 has affected all countries directly. Socio-economic, educational and religious sectors are adversely affected by COVID-19. Some of the religious events found to have also positive effects on spreading of the pandemic. However, such adverse of COVID-19 effects are likely to continue because of the uncertainty on the eradication of the disease as specific medicine or vaccine is still not available against COVID-19. COVID-19 has paramount effects on socioeconomic, education and religious sectors. Since, the world is not going to be free of COVID-19 in near future as the world is yet waiting for specific vaccine or medicine against the disease, all must learn how to live with COVID-19. However, the world must learn from the current effects of COVID-19 and use to imply them as spotlights to institute future policies to protect the society.
