Problems solved by technology

The pmi selection system has also been used in rice transformation research (Lucca et al.2001; He et al.2004; Ding et al.2006), but the reported transformation efficiencies are very low (only about 6%), which is not suitable for production on an industrial scale

Abstract

The invention provides a method of effectively introducing exogenous genes into rice cells by utilizing PMI (phosphomannose isomerase) selective marker, a transformation system, as well as a preparation method of genetically modified rice by utilizing the method.

Description

technical field [0001] The invention relates to the fields of plant genetics and genetic engineering. More specifically, the present invention relates to a method for preparing transgenic rice using Agrobacterium-mediated and PMI selectable markers. Background technique [0002] Rice (Oryza sativa) is the staple food for more than half of the world's population, especially in Asian countries. As the population expands and arable land decreases, rice production is becoming increasingly difficult to meet demand. By 2050, the world population will increase from the current 6.7 billion to 9.2 billion (United Nations, 2007), which requires an additional 50% increase in food supply by 2050. With the popularization of semi-dwarf varieties and hybrid rice, transgenic methods are expected to become another breakthrough point for increasing rice production. After the completion of the rice genome sequencing in 2002, the functional annotation of open reading frames and the applicati...
