title: DELLA-PIF Modules: Old Dogs Learn New Tricks.
abstract: DELLA proteins are central regulators in gibberellin (GA) signaling that interact with PHYTOCHROME-INTERACTING FACTORS (PIFs) and block their DNA-binding capacity, impairing their function in integrating light signals. A recent report demonstrates that DELLAs also negatively control PIF stability, thus providing a new layer of coordination of light and GA signaling.
