Auxin Pathway
The auxin pathway represents a core plant hormone system governing stem elongation, root development, and apical dominance—traits of direct relevance to cannabis breeding. Auxin (indole-3-acetic acid, or IAA) and its signaling cascade influence plant architecture, branching patterns, and internodal spacing. Breeders working in this category often select for auxin-responsive phenotypes to achieve desired canopy structure, height control, and lateral branching intensity. Mutations or natural variation in auxin biosynthesis and transport genes can produce compact, bushy forms or tall, columnar types. Understanding auxin regulation is foundational to developing cultivars suited to specific growing environments and production goals.

Breeders leverage auxin pathway genetics to manipulate plant structure without chemical regulators. Selections for enhanced or suppressed lateral branch formation, internode length, and root vigor rely on heritable auxin-signaling variation.
