Abstract excerpt
Genes for histidyl-aspartyl (His-Asp) phosphorelay components (His-containing phosphotransfer proteins, HP, and response regulators, RR) were isolated from Zea mays L. to characterize their function in cytokinin signaling. Six type-A RRs (ZmRR1, ZmRR2, ZmRR4-ZmRR7), 3 type-B RRs (ZmRR8-ZmRR10), and 3 HPs (ZmHP1-ZmHP3) were found in leaves. All type-A RR genes expressed in leaves were up-regulated by exogenous...
