Overexpression of a methyl-CpG-binding protein gene OsMBD707 leads to larger tiller angles and reduced photoperiod sensitivity in rice

Abstract Background Methyl-CpG-binding domain (MBD) proteins play important roles in epigenetic gene regulation, and have diverse molecular, cellular, biological functions plants. MBD been functionally characterized various plant species, including Arabidopsis , wheat, maize, tomato. In rice, 17 sequences were bioinformatically predicted as putative proteins. However, very little is known regarding the function of rice. Results We explored expression patterns rice OsMBD family genes identified 13 OsMBDs with active tissues. further a class I protein OsMBD707, demonstrated that OsMBD707 constitutively expressed localized nucleus. Transgenic overexpressing displayed larger tiller angles reduced photoperiod sensitivity—delayed flowering under short day (SD) early long (LD). RNA-seq analysis revealed overexpression led to sensitivity changes regulator Ehd1-Hd3a / RFT1 pathway. Conclusion The results this study suggested plays growth development, should lead studies on growth, or other processes
