Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, EarlyView.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

A Novel Dual‐Target Compound Designed With Potent Herbicidal and Fungicidal Activity Inspired by Conserved Phytoene Synthase Domains

Plant Biotechnology Journal, EarlyView.
ABSTRACT The development of dual‐target inhibitors represents a cost‐effective strategy for integrated pest management. Here, we report the first dual‐target inhibitors designed against the evolutionarily conserved domain of phytoene synthase (PSY), a key enzyme in carotenoid biosynthesis.

Tandem MADS‐Box Genes FUL2 and MADS1 Form a Regulatory Module to Repress Serotonin Biosynthesis via Direct ASMT5 Activation in Tomato Fruit

Plant Biotechnology Journal, EarlyView.
ABSTRACT The regulation of serotonin metabolism during fruit development and ripening remains poorly understood, despite its potential roles in plant defence and human nutrition. Here, we demonstrated that the MADS‐box transcription factor FUL2 acts as a key repressor of serotonin accumulation in tomato by forming a functional module with MADS1. CRISPR‐
