“…In addition, the expression of OsCNGC9 is enhanced by OsDREB1A, leading to enhanced OsCNGC9-mediated Ca 2+ influx and chilling tolerance in rice (Figure 7). Our model is consistent with earlier reports that OsSAPK8 functions as a positive regulator of responses to abiotic stresses, including cold stress (Zhong et al, 2020), and that Arabidopsis OST1, a homolog of rice OsSAPK8, positively regulates cold tolerance by phosphorylating critical regulators upstream of CBFs (Ding et al, 2015(Ding et al, , 2018(Ding et al, , 2019. Together with these previous findings, our results suggest that a conserved regulatory mechanism composed of SnRKs-CNGCs may regulate cold-triggered cytoplasmic calcium elevation and chilling tolerance in both monocots and dicots.…”

“…To further test whether OsSAPK8 plays a role in the regulation of rice chilling tolerance, we conducted a chilling tolerance assay using two independent OsSAPK8 knockout lines (Supplemental Figure 9). Consistent with a previous study (Zhong et al, 2020), the survival rate of the OsSAPK8 knockout mutant plants was clearly lower than that of the corresponding WT (Nipponbare) seedlings after chilling treatment (Figure 5A and 5B; Supplemental Figure 2D). Interestingly, a Ca 2+ flux assay showed that root cells of Nipponbare but not those of the OsSAPK8 knockout mutants exhibited more significant Ca 2+ influx after cold treatment ( Figure 5C and 5D).…”

“…Members from plant SnRK2 subfamily usually participate in response to various abiotic stresses. For examples, SnRK2.3 regulates drought response in Arabidopsis; SAPK8 and TaSnRK2.3 regulate freezing, drought and salt tolerance of rice and wheat respectively (Tian et al 2013;Tan et al 2018;Zhong et al 2020).…”

“…There are three subfamilies of SnRKs, including SnRK1s, SnRK2s and SnRK3s [25,26]. The SnRK2 and SnRK3 subfamily are mostly involved in stress and abscisic acid (ABA) signaling [27][28][29][30][31], while SnRK1s regulate carbohydrate metabolism and is crucial for normal development and response to stress [32][33][34]. The SnRK1 exist as heterotrimeric holoenzyme, comprising a catalytic α subunit, a regulatory γ or βγ subunit, and β subunit as a scaffold linking α and γ subunits [35,36].…”
