Tree size and structure are major drivers of orchard productivity, labor efficiency, and overall sustainability. Our research focuses on uncovering the physiological and molecular processes that shape citrus canopy architecture, with particular interest in the mechanisms that generate naturally compact or semi-dwarf trees. By integrating developmental studies with genomic, transcriptomic, and molecular analyses, we aim to define the regulatory networks that control growth patterns. These insights support the design of next-generation orchards- high-density, high-yield systems that are easier to manage and better suited to modern agricultural challenges.
