The Arabidopsis AtIPT8/PGA22 gene encodes an isopentenyl transferase that is involved in de novo cytokinin biosynthesis.

Original language description

Cytokinin plays a critical role in plant growth and development by stimulating cell division and cell differentiation. Despite many years' research efforts, our current understanding of this hormone is still limited regarding both its biosynthesis and signaling. To genetically dissect the cytokinin pathway, we have used a functional screen to identify Arabidopsis gain-of-function mutations that enable shoot formation in the absence of exogenous cytokinins. By using a chemical-inducible activation tagging system, we have identified over 40 putative mutants, designated as pga (plant growth activators), which presumably were affected in key components of cytokinin biosynthesis and signaling pathway. Here, we report a detailed characterization of pga22, arepresentative mutant from this collection. A gain-of-function mutation in the PGA22 locus resulted in typical cytokinin responses. Molecular and genetic analyses indicated that PGA22 encodes an isopentenyl transferase (IPT) previously id
