Rev. Plant Biol., 59, p.225-251, 20083 aBioactive gibberellins (GAs)are diterpene plant hormones that are biosynthesized through complex pathways and control diverse aspects of growth and development. Biochemical, genetic, and genomic approaches have led to the identification of the majority of the genes that encode GA biosynthesis and deactivation enzymes. Recent studies have highlighted the occurrence of previously unrecognized deactivation mechanisms. It is now clear that both GA biosynthesis and deactivation pathways are tightly regulated by developmental, hormonal, and environmental signals, consistent with the role of GAs as key growth regulators. In some cases, the molecular mechanisms for fine-tuning the hormone levels are beginning to be uncovered. In this review, I summarize our current understanding of the GA biosynthesis and deactivation pathways in plants and fungi, and discuss how GA concentrations in plant tissues are regulated during development and in response to environmental stimuli.14aBIOSYNTHESIS14aCYTOCHROME P450 MONOOXYGENASE14aDEACTIVATION14a2-OXOGLUTARATE-DEPENDENT DIOXYGENASE14aPLANT HORMONES14aTERPENE SYNTHASES12aYamaguchi, S.40uhttps://drive.google.com/file/d/1oMIBuJ7XydHCqtFswLEB5SiTXEJW0TXp/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx250602s9999    xx |||||s2   |||| ||und|d
