Abstract: Background: Glutathione (GSH) is important for plants to resist abiotic stress, and a large amount of energy is required in the process. However, it is not clear how the energy status affects the accumulation of GSH in plants under cold stress. Results: Two rice pure lines, Zhongzao39 (ZZ39) and its recombinant inbred line 82 (RIL82) were subjected to cold stress for 48 h. Under cold stress, RIL82 suffered more damages than ZZ39 plants, in which higher increases in APX activity and GSH content were showed in t… Show more

“…Substrate inhibition was also found at ATP concentrations exceeding 4 mM. If we convert literature data (25-35 nmol g −1 fw; e.g., Yu et al, 2020) into molar levels on the assumption of an intracellular volume (excluding vacuoles) equal to about 2-4% of the total water content in rice leaves, the concentration of ATP in the cell should range from 0.6 to 1.5 mM. It is therefore likely that such inhibition does not have a physiological role.…”

“…The cold stress inducing changes in the plant growth and development is tightly linked to the intracellular auxin gradient (Rodrigues et al 2009 ; Rahman 2013 ). Glutathione (GSH) is one of the most important factors for rice plants to resist cold stress, and a large amount of NAD + is required in this process (Yu et al 2020 ). ONT.3262.1 encodes l-aspartate oxidase in I. indigotica , and ATASPO is a key metabolic step to catalyze NAD + synthesis (Hao et al 2018 ).…”

“…Low temperatures increase the GSH level many folds which in turn alters the redox status of GSH (Wildi and Lütz, 1996;Karpinski et al, 1997). GSH accumulation was seen to be more evident in cold tolerant varieties of rice as compared to non-tolerant (Yu et al, 2020). Cold stress can inhibit some metabolic activity of plants (Shi Y. et al, 2018).…”
