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...

Thermo-sensitivity and Photoperiod Sensitivity Genes Controlling Heading Time and Flower Bud Initiation in Sorghum, Sorghum bicolor Moench
AFLP complementary gene effect daylength heading response inheritance
2011/2/24
The timing of heading and flower bud initiation is critical for reproductive success. In sorghum (Sorghum bicolor Moench), which is a facultative short-day plant, we propose that the thermo-sensitivit...
