Even closely related plants produce their own natural chemical cocktails, each set uniquely adapted to the individual plant’s specific habitat. Comparing anti-fungals produced by tobacco and henbane, an international team of researchers discovered that only a few mutations in a key enzyme are enough to shift the whole output to an entirely new product mixture. Making fewer changes led to a mixture of henbane and tobacco-specific molecules and even so-called “chemical hybrids,” explaining how plants can tinker with their natural chemical factories and adjust their product line to a changing environment without shutting down intracellular chemical factories completely.
