| truncated ubiquitin 5' regulatory region from erianthus arundinaceus drives enhanced transgene expression in heterologous systems. | characterization of novel plant gene promoters underpins the development of transgenic crop plants. here, we report a novel 5' regulatory sequence (eriubi d7) of the ubiquitin gene from erianthus arundinaceus, a wild relative of sugarcane resistant to many biotic and abiotic stresses. a 3.2-kb regulatory sequence of ubiquitin gene was isolated through random amplification of genomic ends technique and characterized in rice, tobacco, and sugarcane. in silico analysis revealed that the regulatory ... | 2015 | 25985900 |
