Core Viewpoint - The article discusses recent research that uncovers the biosynthesis pathway of salicylic acid in plants, which is crucial for their defense mechanisms and has implications for developing disease-resistant crop varieties [4][14][20]. Group 1: Research Findings - A team from Sichuan University published a study in Nature revealing a three-step biosynthesis pathway of salicylic acid from benzoyl-CoA in plants [4][5]. - The study identified three key enzymes involved in this pathway: BEBT, BBO, and BSH, which are conserved across various plant species [13][14]. - The research provides a molecular basis for understanding the differences in disease resistance among different plant groups, particularly major food crops [6][14]. Group 2: Comparative Studies - Concurrently, two other studies from Zhejiang University and Zhejiang Normal University also published in Nature focused on the biosynthesis of salicylic acid from phenylalanine, contributing to a more comprehensive understanding of this process [16][18][20]. - These studies collectively address the long-standing gaps in knowledge regarding salicylic acid biosynthesis pathways in plants [20].
