Comparative analysis of the transcriptomes from regenerated plants and root explants of endangered Oplopanax elatus.

Background: Oplopanax elatus is a plant of therapeutic significance in oriental medicine; however, its mass cultivation is limited owing to the difficulties in propagating it from seeds.

Methods: In this study, we investigated the transcriptome profiles and transcriptional regulatory factors expressed during plantlet regeneration from root tissues of the endangered O. elatus.

The effect of different LED wavelengths on the components and biosynthesis of isoflavonoid in sprout Astragalus membranaceus.

An artificial light source is the optimal element for studying the usability of the medicinal plant Astragalus membranaceus as a sprout vegetable. Based on artificial light source conditions, formononetin (FO) level was the highest (2.6 mg/L) in A.
