Wolfgang Busch, Ph.D., associate professor in the plant molecular and cellular biology laboratory at Salk, presented "To grow or not to grow - novel genetic and molecular mechanisms that determine root growth" as part of the Research Seminar Series at 9 a.m., Thursday, Oct. 5.
Auxins, which are naturally found in plants, trigger root formation. Scientists are testing ways to improve how auxins are absorbed and used by plant cells.
Researchers at Noble are developing tools to better understand how roots sense their environment, including the soil in which they grow. By studying calcium as a carrier of messages within the root, they expect to build knowledge that will lead to grazing lands that are more resilient to harsh environments.
