K1 Fenilalanina - Síntesis
AB Plants rely on the biosynthesis of L-Phenylalanine as building block for the synthesis ofproteins but also as precursor for a tremendous range of plant-derived compoundsessential for its grown, development and defense. Polymerization of secondary cell wallin trees involves the massive biosynthesis, among others, of the Phe-derived compoundlignin. Thus, these plants require an accurate metabolic coordination between Phe andlignin biosynthesis to ensure its normal development. We have here identified that thepine arogenate dehydratase, whose enzyme activity limits the biosynthesis of Phe inplants, is transcriptionally regulated through direct interaction with PpMyb8. We havealso shown that this transcription factor is directly involve in secondary cell wallbiogenesis and cell death processes. Together these results indicate that a singletranscription factor coordinates lignin accumulation and the proper biosynthesis of itsessential precursor L-Phe.
