Endogenous Nod-Factor-like Signal Molecules Promote Early Somatic Embryo Development in Norway Spruce

Embryogenic cultures of Norway spruce (Picea abies) are composed of pro-embryogenic masses (PEMs) and somatic embryos of various developmental stages. Auxin is important for PEM formation and proliferation. In this report we show that depletion of auxin blocks PEM development and causes large-scale...
