Emergence of isochorismate-based salicylic acid biosynthesis within Brassicales

Proceedings of the National Academy of Sciences, Volume 122, Issue 29, July 2025.
SignificanceThe evolution of nonclustered biosynthetic pathways involving multiple genes remains a fundamental question in evolutionary biology. The isochorismate (IC) pathway for salicylic acid (SA) biosynthesis exemplifies how a complex, nonclustered …
