|a To characterize the hormonal regulation of nitrogen remobilization from source to pod filling in Brassica napus, the hormonal level, proteolytic process, and amino acid transport were assessed in mature leaves of pod-removed or control at the early pod-filling stage. Pod (sink) removal decreased salicylic acid (SA), and significantly increased jasmonic acid (JA). The SA/JA ratio decreased with pod removal, accompanied by low degradation of foliar proteins and Rubisco content. A significant decrease in protease activity was observed in pod-removed leaves, confirmed by in-gel staining of protease. Pod removal reduced the expression of four amino acid transporter genes (BnAAP1, BnAAP2, BnAAP4, and BnAAP6) in mature leaves and reduced amino acid loading into phloem. These results indicated that a decrease in SA resulting from pod removal down-regulated nitrogen remobilization accompanied by a decrease in proteolytic activity and amino acid transport in mature leaves at the pod-filling stage
