Multi-omics integration identifies GmISO5 as a key regulator of seed isoflavone biosynthesis and implicates it in the response to soybean mosaic virus.
INTRODUCTION Isoflavones are specialized metabolites that accumulate abundantly in soybean seeds, contributing to nutritional quality, human health benefits, and plant defense. Although the core isoflavone biosynthetic pathway has been well characterized, its upstream regulatory network and potential relationship with...
