In this work, CdS nanoparticles (CdS NPs) biosynthesized through Arabidopsis thaliana phytochelatin synthase-modified Escherichia coli (CdS/AtPCS1-E. coli) with fluorescence (FL) performance for detection of pyrogallol and gallic acid was investigated. Through expression of the AtPCS1 gene inside E.
l-Galactose dehydrogenase (l-GalDH), a novel enzyme that oxidizes l-Gal to l-galactono-1,4-lactone (l-GalL), has been purified from pea seedlings and cloned from Arabidopsis thaliana. l-GalL is a proposed substrate for ascorbate biosynthesis in plants, therefore the function of l-GalDH in ascorbate
