Insights into nitric oxide-mediated water balance, antioxidant defence and mineral homeostasis in rice (Oryza sativa L.) under chilling stress

Popis výsledku v původním jazyce

Being a chilling-sensitive staple crop, rice -Oryza sativa L.- is vulnerable to climate change. The competence of rice to withstand chilling stress should, therefore, be enhanced through technological tools. The present study employed chemical intervention like application of sodium nitroprusside -SNP- as nitric oxide -NO- donor and elucidated the underlying morpho-physiological and biochemical mechanisms of NO-mediated chilling tolerance in rice plants. At germination stage, germination indicators were interrupted by chilling stress -5,0 +/- 1,0 degrees C for 8 h day-1-, while pretreatment with 100 mu M SNP markedly improved all the indicators. At seedling stage -14-day-old-, chilling stress caused stunted growth with visible toxicity along with alteration of biochemical markers, for example, increase in oxidative stress markers -superoxide, hydrogen peroxide, and malondialdehyde- and osmolytes -total soluble sugar, proline and soluble protein content, SPC-, and decrease in chlorophyll -Chl-, relati
