 Phylogenetic relationship among type-A response regulator proteins from rice (OsRR), maize (ZmRR), and Arabidopsis (ARR). The unrooted tree was generated using ClustalX program by neighbor-joining method and visualized by Treeview. Scale bar represents 0.1 amino acid substitution per site.

 The induction of OsRR genes by cytokinin even in the absence of de novo protein synthesis qualifies them to be primary cytokinin response genes.
 OsRR3 and OsRR5 mainly act as negative regulators of cytokinin signaling, as indicated by the reduced sensitivity of OsRR3 and OsRR5 overexpressors to exogenous ytokinins.
 ===Expression===
 Three A-type RR genes(OsRR4, OsRR9and OsRR10 for O. sativa RR) showed cytokinin-induced expression, and three (OsRR8, OsRR12andOsRR13) showed expression in flower.

 With increasing cytokinin:auxin ratios, larger calli were formed and green shoots were longer (Figure 4A). Both pACT1:OsRR3 and pACT1:OsRR5 formed smaller calli and shorter shoots with concentrations of hormones that were able to induce ZH11 calli (Figure 4B and C). The decrease in sensitivity to hormones of pACT1:OsRR3 and pACT1:OsRR5 in callus and shoot formation showed that both OsRR3 and OsRR5 act as negative regulators of the cytokinin-signaling system.

 Analysis of root elongation and lateral root formation during overexpression of OsRR3 and OsRR5 in transgenic rice and ZH11 (CK) in the presence of exogenous hormones. A., B., C.Seeds were grown on plates supplemented with the specified concentrations of BA, 2,4-D, ABA, or DMSO control, under a 16-h photoperiod
 at  23°C.  Error  bars  represent  SE  (N =  30).  D. Seeds  were  grown  on  plates  supplemented  with  the  specified concentrations of BA control under a 16-h photoperiod at 23°C. The total number of lateral roots was determined at 15 days. Error bars represent SE (N= 30). E.Phenotypes of roots for 16-day-old seedlings of (from left to right) ZH11, pACT1:OsRR3, and pACT1:OsRR5 treated with 0.5 μM BA under a 16-h photoperiod.
