trans-Ribosylzeatin: Its Biosynthesis in Zea mays Endosperm and the Mycorrhizal Fungus, Rhizopogon roseolus.
When [8-(14)C]-N(6)-(Delta(2)-isopentenyl) adenosine is incubated with the endosperm of corn (2 weeks after pollination), it is converted to [(14)C]-N(6)-(4-hydroxy-3-methylbut-2-trans-enyl) adenosine, trans-ribosylzeatin. This biosynthetic step, N(6)-(Delta(2)-isopentenyl) adenosine to ribosylzeatin, also occurs in the mycorrhizal fungus, Rhizopogon roseolus.
