incubated in medium containing 1000 ng/ml ...
Optimization of the Cry2Aa gene and development of insect-resistant and herbicide-tolerant photoperiod-sensitive genic male sterile rice
Bar gene Cry2Aa# gene herbicide tolerance insect resistance PGMS line rice
2014/3/31
In this study, an optimized Cry2Aa gene was obtained after codon optimization based on the preferred codons in rice. The novel fusion gene Cry2Aa# was designed by adding the sequence coding the signal...
