Open AccessTrichomeLess Regulator 3 is required for trichome initial and cuticle biosynthesis in Artemisia annua
Artemisinin is primarily synthesized and stored in the subepidermal space of the glandular trichomes of Artemisia annua. The augmentation of trichome density has been demonstrated to enhance artemisinin yield. Ho...

Open AccessStructure-based engineering of substrate specificity for pinoresinol-lariciresinol reductases
Pinoresinol–lariciresinol reductases (PLRs) are enzymes involved in the lignan biosynthesis after the initial dimerization of two monolignols, and this represents the entry point for the synthesis of 8-8′ lign...

Open AccessTargeted expression of Vitreoscilla hemoglobin improves the production of tropane alkaloids in Hyoscyamus niger hairy roots
Under hypoxic conditions, the expression of Vitreoscilla hemoglobin (VHb) in plants is proposed to increase the productivity of certain oxygen-requiring metabolic pathways by promoting the delivery of oxygen. Tro...

Characterization of a novel ERF transcription factor in Artemisia annua and its induction kinetics after hormones and stress treatments
The full-length cDNA sequence of AaERF3 was cloned and characterized from Artemisia annua. The bioinformatic analysis and phylogenetic tree analysis implied that the AaERF3 encoded a putative protein of 193 amino...
