Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description It encodes for the enzyme cytokinin nucleoside 5'-monophosphate
phosphoribohydrolase that converts the cytokinin nucleotide such as iPRMP and
tZRMP to the free-base form and ribose 5'-monophosphate. The active cytokinin
species are free-base forms isopentenyladenosine (iP) and trans-Zeatin (tZ,
cytokinin). The gene in involved in cytokinin biosynthesis and meristem
maintenance in the shoot apical meristem (SAM). gene is expressed in SAM,
inflorescence and flower meristems. The mutant plants show reduced number of
active meristematic cells in SAM, arrest of inflorescence lateral meristem
leading to few inflorescence brances and small size of panicle, , floral
meristem flattens and its differentiation is arrested just before the pistil
primordium formation. The flowers lack pistil (the female part), therefore the
gene was named "lonely guy".
