Salk researchers chart landscape of genetic and epigenetic regulation in plants

LA JOLLA—A new technique developed by Salk Institute scientists for rapidly mapping regions of DNA targeted by regulatory proteins could give scientists insight into what makes some plants drought tolerant or disease resistant, among other traits.

Revealing this landscape of protein-binding zones on DNA, collectively dubbed the “cistrome,” shows how plants control where and when genes are expressed. Previous methods for mapping the cistrome in plant cells were difficult and slow, but the new approach, detailed in the May 19, 2016 issue of Cell, overcomes those hurdles to offer a sweeping view of this critical aspect of genetic regulation.
