| Abstract/Contents: | "Tillering is key to turfgrass establishment and recovery. Understanding the molecular mechanism of tillering in turfgrass is of great importance for molecular breeding. Here we cloned the ortholog of teosinte branched1 (tb1) in maize, which we named as FaTB1 in tall fescue and found it localized in the nuclear. FaTB1 was most abundantly expressed in the tiller bud. Transgenic tall fescue plants that overexpressing FaTB1 produced fewer tillers than the control plants. Further analysis showed that tiller reduction was specially caused by tiller bud arrest. 13 FaHD-Zip I genes were cloned and one of the factor (FaHOX12) exhibited co-expression pattern as FaTB1. In addition, FaHOX12 was up-regulated in the transgenic plants which indicated it may act downstream of FaTB1. Yeast one hybrid showed that FaTB1 could bind to the cis-element in FaHOX12 promoter. This study first reported the FaTB1/FaHD-Zip I pathway in monocotyledonous plants that specially regulate tiller bud outgrowth in turfgrass species." |
