摘要: This chapter emphasizes recent biochemical advancements in alkaloid biosynthesis and on the biological aspects of nicotine biosynthesis. Nicotine is principal alkaloid, usually accounting for greater than 90% fraction, commercial tobacco. Nornicotine, anatabine, anabasine are other predominant alkaloids tobacco, but seldom do they individually accumulate to more 5% total fraction. Genes at two nonlinked loci, Nicl , Nic2 primarily control content The Nic genes expressed mainly plant roots result expression measured as leaf content. biology likely evaluate transformed root tissues growth regulator effects synthase catalyzes last step biosynthesis, decarboxylation, condensation.
