Protein lysine acylation, such as succinylation and acetylation are important posttranslational modification (PTM) mechanisms, with key roles in the regulation of diverse metabolic and cellular processes. Antibody-based affinity enrichment, high-resolution LC-MS/MS analysis and integrated bioinformatics analysis, were used to characterize the lysine succinylome (Ksuc) and acetylome (Kace) in rice leaves. Rice (Oryza sativa., Wuyunjing 7) was kindly provided byJiangsu Academy of Agricultural Sciences, Jiangsu Province, China. Rice seeds were surface-sterilized with 5% NaClO for 20 min, washed extensively with distilled water and then germinated in distilled water at 28ÂșC for 2 days. Germinated seeds were cultivated on half-strength ammonium-free Murashige and Skoog (MS) medium. For oxidative stress treatments, 14-days-old rice seedlings were transferred to 1/2 MS medium in the absence or presence of 1 mM H2O2 for 6 days. Rice seedlings were then harvested for protein extraction.
