Abstract

In plants, the developmental relaxation of transposable element silencing (DRTS) occurs at distinct spatial and temporal points in the normal development of a wild-type individual. Several examples of DRTS have now been described, including in maize shoot apical meristems, and in Arabidopsis meiocytes, endosperm and nurse cells of gametophytes. In this opinion article, we review the known DRTS events and speculate on the function, if any, of DRTS in plants.
