WEREWOLF, a regulator of root hair pattern formation, controls flowering time through the regulation of FT mRNA stability.

abstract：:Membrane trafficking and cytoskeletal dynamics are important cellular processes that drive tip growth in root hairs. These processes interact with a multitude of signaling pathways that allow for the efficient transfer of information to specify the direction in which tip growth occurs. Here, we show that AGD1, a class...
