Chemical profiling of insect-resistant rice shows that geographical variations produce greater differences in chemical composition than genetic modifications
Genetically modified (GM) rice (event, Bt-T) contains the Bacillus thuringiensis gene for insecticidal properties. To evaluate changes in the chemical compositions of Bt-T and non-GM rice cultivated in two region...

The Tomato Juhwang Mutant Accumulates a High Level of β-Carotene and has a Long Shelf-Life
Carotenoids have diverse functions in plants and animals. In tomato (Solanum lycopersicum), the red color of fruits is due to the accumulation of the carotenoid lycopene during fruit ripening. Here, the effect of...
