Arabidopsis telomerase takes off by uncoupling enzyme activity from telomere length maintenance in space

NATURE COMMUNICATIONS, 14(1).

By: B. Barcenilla *, A. Meyers *, C. Castillo-Gonzalez *, P. Young*, J. Min *, J. Song *, C. Phadke*, E. Land n  ...

TL;DR: No changes in telomere length in space-flown Arabidopsis seedlings are observed, despite a dramatic increase in telomerase activity (up to 150-fold in roots), as well as elevated genome oxidation, and it is proposed that genome oxidation is inversely correlated with telomersase activity levels.
