Cloning of Choline Monooxygenase (CMO) Gene and Expression Analysis of the Key Glycine Betaine Biosynthesis-Related Genes in Tea Plant (Camellia sinensis)

Objective) Choline monooxygenase gene (CMO), one of the key enzyme genes in biosynthesize pathway of glycine betaine (GB) in plant, was cloned from tea plant (Camellia sinensis). The expression patterns of CsCMO and the other GB biosynthesis-related gene, CsBADH (betaine aldehyde dehydrogenase), under different abiotic stresses and in different cold resistant
