Abstract

To explore the adaptation mechanisms of Kandelia candel (L.) Druce in response to daily flooding, a large-scale quantitative lysine acetylome was carried out using immunoaffinity enrichment of Lys-acetylated peptides and liquid chromatography linked to tandem mass spectrometry. A total of 1041 lysine acetylation (LysAc) sites, 1021 Lys-acetylated peptides and 617 Lys-acetylated proteins were identified. Six conserved sequence motifs of the LysAc sites, including a new motif KxxxxK, were detected. Among these proteins, 260 were differentially acetylated in response to flooding, which were preferentially predicted to participate in carbon metabolism and photosynthesis pathways based on KEGG pathway category enrichment analysis. Consistently, the transcriptional level of acetyltransferase and the consumption of acetyl-CoA were up-regulated under flooding conditions. Most of physiological parameters and mRNA expression levels related to carbon metabolism and photosynthesis were found to be insignificantly affected by flooding. Taken together, reversible protein LysAc is likely to be a post-translational mechanism contributing to the mangrove K. candel's adaptation to daily flooding.
