Isolation of a choline monooxygenase cDNA clone from Amaranthus tricolor and its expressions under stress conditions
Plants synthesize the osmoprotectant glycine betaine (GB) via choline→ betaine aldehyde→glycine betaine1. Two enzymes are involved in the pathway, choline monooxygenase (CMO) and betaine aldehyde dehydrogenase (B...

Molecular cloning and functional characterization of two kinds of betaine-aldehyde dehydrogenase in betaine-accumulating mangrove Avicennia marina (Forsk.) Vierh.
Glycinebetaine is an important osmoprotectant in bacteria, plants, and animals, but only little information is available on the synthesis of glycinebetaine in tree plants. Among four mangrove species, glycineb...

Ri-mediated transformation of Artemisia annua with a recombinant farnesyl diphosphate synthase gene for artemisinin production
A transgenic system was developed for Artemisia annua L. via Agrobacterium rhizogenes-mediated transformation. Using this system a cDNA encoding farnesyl diphosphate synthase (FDS) placed under a CaMV 35S promote...

Plant regeneration from protoplasts isolated from callus ofGentiana crassicaulis
Fast growing calli induced from hypocotyl segments ofGentiana crassicaulis were used for preparation of protoplasts. High yields of viable protoplasts were produced in an enzyme solution containing 1–2% cellulase...
