Prohibitin 3 gives birth to a new lateral root primordium.

PHB3 regulates lateral root primordia formation via NO-mediated degradation of AUXIN/INDOLE-3-ACETIC ACID proteins ACID proteins. The molecular network of PHB3 and NO in regulating LR initiation Prohibitin 3 (PHB3) induces nitric oxide (NO) accumulation to promote lateral root (LR) initiation. This process is activated by an auxin/indole-3-acetic acid (AUX/IAA)-AUXIN RESPONSE FACTOR (ARF)-dependent auxin signaling cascade.
