Experiments Regarding the Problem of Differentiation in Multicellular Systems

摘要: The temporal pattern of control by phytochrome the enzyme lipoxygenase (EC 1.13.1.13) in mustard seedling (Sinapis alba L.) is described. biosynthetic system which produces does not respond to (Pfᵣ) up 33.25 h after sowing (25°C). By this time Pfᵣ comes suddenly and fully into play. At 48 escapes from Pfᵣ. Neither beginning nor end period influenced phytochrome. Interpretation data requires a double action mechanism. It argued that such mechanism necessarily characteristic development multicellular organism.
