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.

The Circadian-clock Regulates the Arabidopsis Gravitropic Response

Gravitational and Space Research.

By: J. Tolsma n, K. Ryan n, J. Torres*, J. Richards*, Z. Richardson n, E. Land n, I. Perera n, C. Doherty n

TL;DR: Gravitropic responses were disrupted in plants with disrupted circadian clocks, including plants overexpressing Circadian-clock Associated 1 (CCA1) and elf3-2, in the reorientation assay and on a 2D clinostat suggesting the variation is circadian-regulated. (via Semantic Scholar)
