摘要: Nitrogen (N) is one of the basic nutrients and signals for plant development and deficiency of it would always limit the productions of crops in the field. Quantitative research on expression of N-stress responsive proteins on a proteome level remains elusive. In order to gain a deep insight into the proteins responding to nitrogen stress in rapeseed (Brassica napus L.), comparative proteomic analysis was performed to investigate changes of protein expression profiles from the root, stem and leaf under different N concentrations, respectively. More than 200 dif-ferential abundance proteins (DAPs) were detected and categorized into groups according to annotations, includ-ing "binding and catalytic activity", "involved in primary metabolism and cellular processes", "stress-response" and so on. Variation in chlorophyll (Chl) content and antioxidant activities further revealed that oxidative stress raised with the increase of N concentration. Bioinformatics analysis based on the expression level of total proteins suggested these DAPs might play important roles in adaptation to N-stress conditions. Generally, these results provides a new aspect into N-stress responding proteins in Brassica plants.
