Heterchronic shifts in a timing-keeping microRNA are associated with multiple instances of neoteny in plants

Aaron R. Leichty, R. Scott Poethig

This study investigates neoteny in Acacia plants and finds that prolonged juvenile traits are linked to changes in miR156 expression timing, not loss of adult trait capacity.

Low light intensity delays vegetative phase change in Arabidopsis thaliana

Mingli Xu, Tieqiang Hu, R. Scott Poethig

This study shows that low light intensity in Arabidopsis thaliana delays vegetative phase change by increasing miR156/miR157 and reducing SPL expression, independent of photoreceptors involved in shade avoidance.
