Researchers discover key gene for toxic alkaloid in barley

All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley‚ one of the world's most widely-grown cereals. Gramine provides protection against herbivorous insects and grazing animals and inhibits the growth of other plants. Despite long-standing interest‚ the key gene for the formation of gramine remained elusive.
