DURHAM, N.C. -- A team of botanists is untangling the subterranean travels of plant roots by using DNA analysis to identify samples of roots that have pushed their way into caves. The scientists' insights into this topsy-turvy "underground forest" will contribute not only to a better understanding of the strategies plants use to seek life-giving water and nutrients, but also to improved ecosystem models of how vegetation and climate might interact in a future of global change.
