WebALTHOUGH phloroglucinol itself seldom occurs in plants it has been implicated in the biosynthesis of ring A of the flavonoid compounds 1,2. In Pseudomonas fluorescens, biosynthesis of phloroglucinol is performed with a type III polyketide synthase. The synthesis begins with the condensation of three malonyl-CoAs. Then decarboxylation followed by the cyclization of the activated 3,5-diketoheptanedioate product leads to the formation of phloroglucinol. ecf s.d. indiana
