Endogenous phytohormone profiles during Norway spruce somatic embryogenesis
Somatic embryogenesis (SE) in conifers is governed by a complex network of hormonal metabolic and signaling pathways. Changes in the patterns and concentrations of endogenous phytohormones including auxins, cytokinins (CKs), abscisic acid (ABA), jasmonates, and salicylic acid (SA) were analyzed in the course of SE in Norway spruce (Picea abies).
