Project description:Lonicera japonica Thunb., known as Jin Yin Hua or Japanese honeysuckle, is an herbal medicine in Asian countries. Its flowers have been used as folk medicine for clinical practice or used as food or making healthy beverage for 1500 years in China. To investigate the molecular developmental processes from L. japonica buds to flowers under UV radiation, comparative proteomics analyses of buds and flowers were performed. Fifty-four differential proteins were identified including 42 increased proteins and 12 decreased proteins. The abundance of proteins related to glycolysis, TCA/organic acid transformation, major carbohydrate metabolism, oxidative pentose phosphate, stress, secondary metabolism, hormone, and mitochondrial electron transport were increased during flower opening process under UV radiation. Six metabolites were identified and relatively quantified by LC-MS/MS in L. japonica buds and flowers. The 1,1-diphenyl-2-picrylhydrazyl assay revealed that antioxidant activity of L. japonica buds was better than that of flowers. These results suggest that UV-B radiation could induce the production of endogenous ethylene in L. japonica buds, which facilitate the buds blossom and activate the antioxidant system. Additionally, the higher content of metabolites and antioxidant capability in L. japonica buds indicates that L. japonica buds stage might be the better harvest time compared to the flower.

Project description:Lonicera japonica Thunb is a typical Chinese medicinal material with the homology of medicine and food. Post-translational modification (PTM) of proteins can significantly affect protein structure and function, and plays a very important regulatory role in plant development. However, to date, little is known about the functions of PTM in L. japonica. Therefore, the study of lysine succinylation during the floral developmental stages will help to understand the mechanism of the secondary metabolism of L. japonica. In this study, we first analyzed lysine succinylation exist in L. japonica, and found lysine succinylation is highly abundant in juvenile bud stage than gold flowering stage. Then a highly efficient enrichment method for succinylation peptides was used to identify 586 succinylation modification sites in 303 proteins in L. japonica. Our bioinformatics analysis further revealed that the succinylated proteins are involved in many important biological processes including TCA, amino acid metabolism and secondary metabolism. With the development of flowering stage of L. japonica, the succinylation degree of aspartate transaminase was up-regulated while 4-coumarate-CoA ligase was down-regulated, suggesting that succinylation of proteins is important for the bioactive compounds’ biosynthesis process in L. japonica. Protein modification in vitro also verified the impact of succinylation on both 4CL and AT enzyme activity would be changed. As a consequence, current examine provides new insight into the molecular mechanism underlying the accumulation of active ingredients in L. japonica at the post-translational modification level.
