Purdue research plots new field in plant genomics

Purdue University researchers have developed a new field called 'ionomics,' which studies how genes regulate all the ions in a cell. This research holds promise for creating mineral-efficient plants that need little fertilizer, crops with better nutritional value, and plants that can remove contamination from the soil.
