The contents of another loculus were separated in a pollen and tapetum fraction. The following enzymes involved in phenylpropanoid metabolism were present in the tapetum fraction: shikimate dehydrogenase; phenylalanine ammonialyase; cinnamic acid 4-hydroxylase; SAM (S-adenosylmethionine): caffeate 3-O-methyltransferase; hydroxycinnamate: CoA ligase;(More)
After separation of the contents of anthers into pollen and tapetum fractions, the subcellular localization of tapetum enzymes involved in phenylpropanoid metabolism have been studied by differential centrifugation and by sucrose density gradient centrifugation. The experiments showed that nearly all the activity of both phenylalanine ammonia-lyase and an(More)
