| additional information | generation of transgenic rice lines by RNA interfering or overexpressing gene OscZOG1, encoding a putative zeatin-O-glucosyltransferase. The RNAi transgenic lines exhibit a higher plant height, whereas the plant height of the overexpression lines is reduced with respect to the wild-type seedlings when grown in liquid culture conditions in greenhouse for 2 weeks, drastic enhancement of tiller numbers in the RNAi transgenic lines. Overexpressing OscZOG1 leads to accumulation of cZOG in transgenic plants | Oryza sativa |

| additional information | OscZOG1 is preferentially expressed in shoot and root meristematic tissues and nascent organs. Th strong hybridization signals in the meristematic tissues of inflorescence suggests that OscZOG1 expression is targeted to cells in rapidly growing regions. The early activation of OscZOG1 expression in SAM, leaf primordia and young leaves suggest that OscZOG1 may play a critical role in early seedling growth | Oryza sativa | - |

| spikelet | during early developmental stages of spikelets, the strong hybridization signals are observed in floral meristem (FM) and the primordia of glumes, palea and lemma in out whorls While the stamen primordia are continuing to grow, OscZOG1 expression concentrates on the remaining tissue of the central meristem and developing stamens. At a late stage of spikelet development, the strong hybridization signals are observed in anther locules and filaments | Oryza sativa | - |

| malfunction | constitutive expression of OscZOG1 leads to negative effects on the formation of the grain-yielding traits with a marked increase in the accumulation levels of cis-zeatin O-glucoside (cZOG) in the transgenic rice plants. Growth of lateral roots is stimulated in OscZOG1 overexpression lines, but inhibited in OscZOG1 RNA interference lines. Modulation of OscZOG1 expression affects lateral root development in rice. The RNAi transgenic lines exhibit a higher plant height, whereas the plant height of the overexpression lines is reduced with respect to wild-type seedlings when grown in liquid culture conditions in greenhouse for 2 weeks, drastic enhancement of tiller numbers in RNAi transgenic lines, phenotypes, overview | Oryza sativa |
| physiological function | putative zeatin O-glucosyltransferase OscZOG1 regulates root and shoot development and formation of agronomic traits in rice. Cytokinin plays a central role in regulating the activity of the reproductive shoot apical meristem (SAM), which is one parameter determining seed yield in crop plants. OscZOG1 regulates lateral root development. OscZOG1 is highly expressed in shoot meristematic tissues and functions in early seedling growth and tillering. OscZOG1 modulates adult plant height and flag leaf senescence. OscZOG1 regulates panicle development and seed formation | Oryza sativa |
