Résumé: | Copyright © 2023 Elsevier Masson SAS. All rights reserved. Longan (Dimocarpus longan) is a precious subtropical fruit with high nutritional value. The somatic embryogenesis (SE) affects the quality and yield of fruit. Apart from clonal propagation, SE has extensive applications in genetic improvement and mutation. Thus, understanding the molecular basis of embryogenesis in longan will help to develop strategies for mass production of quality planting material. Lysine acetylation (Kac) plays an important role in diverse cellular processes, but limited knowledge is available regarding acetylation modifications in plant early SE. In this study, the proteome and acetylome of longan embryogenic callus (ECs) and globular embryos (GEs) were investigated. In total, 7232 proteins and 14,597 Kac sites were identified, and this resulted in the discovery of 1178 differentially expressed proteins and 669 differentially expressed acetylated proteins. KEGG and GO analysis showed that glucose metabolism, carbon metabolism, fatty acid degradation, and oxidative phosphorylation pathways were influenced by Kac modification. Furthermore, sodium butyrate (Sb, a deacetylase inhibitor) led to reduced the proliferation and delayed the differentiation of ECs by regulating the homeostasis of reactive oxygen species (ROS) andindole-3-acetic acid (IAA). Our study provides a comprehensive proteomic and acetylomic analysis to aid in understanding the molecular mechanisms involved in early SE, representing a potential tool for genetic improvement of longan |
