Integrated metabolomic and transcriptomic profiling uncovers a citrus terpene synthase with in vivo–in vitro catalytic divergence and psyllid-attracting ecological function
Citrus plants produce a rich diversity of volatile organic compounds (VOCs) that play important roles in fruit aroma, essential oils, and defense against biological stresses in aboveground tissues, yet volatile profiles in citrus roots remain poorly understood. Here, we employed an integrated metabolomic a...
