Update publication information. In this study, LC-MS/MS combined with isobaric chemical labeling technique (iTRAQ) was used to quantify dynamic changes of proteins in N. flagelliforme during the rehydration processes. Approximately 113 proteins were identified to be differentially expressed in photosynthesis, defense response, biosynthesis, antioxidant system, and energy and carbohydrate metabolism. Among them, protective proteins including high light inducible proteins, and antioxidases showed a down regulation trend during the rehydration process, while proteins involved in photosynthesis, biosynthesis and signaling pathways and regulation of gene expression tends to be up-regulated. These results shed light on possible model for the N.flagelliforme response to hydration.
