IntroductionPhytohormones shape the plant above and below ground to enable grounding, interaction with the soil microbiome and with surrounding plants, water and nutrient uptake, organ production, photosynthesis optimization, and seed production. The plant aerial architecture results from the dynamic processes of shoot branching, leaf and flower production following phyllotaxis, and reproduction that originate from the post-embryonic activity of the shoot apical meristem. Hormones influence and coordinate plant development and physiology at the...
