A Purdue University scientist has found genetic evidence of how some plants adapt to live in unfavorable conditions, a finding he believes could one day be used to help food crops survive in new or changing environments. David Salt, a professor of horticulture, noticed several years ago that a variant of the research plant Arabidopsis thaliana that could tolerate higher levels of sodium had come from coastal areas. To test the observation, Salt grew more than 300 Arabidopsis thaliana plants...

Isolating a gene that allows a type of fern to tolerate high levels of arsenic, Purdue University researchers hope to use the finding to create plants that can clean up soils and waters contaminated by the toxic metal. The fern Pteris vittata can tolerate 100 to 1,000 times more arsenic than other plants. Jody Banks, a professor of botany and plant pathology, and David Salt, a professor of horticulture, uncovered what may have been an evolutionary genetic event that creates an arsenic pump of...

Manipulating a natural waxy substance found in plants allows for easier absorption of beneficial nutrients, a Purdue University scientist in Indiana said. Botanists have long believed the substance suberin acted as a barrier for the movement of water in plants. David Salt, a plant molecular physiologist, confirmed the theory by testing a mutant form of the plant Arabidopis, which has twice as much suberin as other varieties of that plant, Purdue said in a release Friday. It's been known for...
