Pattern formation by two-layer Turing system with complementarysynthesis

► We study a two-layer Turing system with complementary synthesis of molecules ► The Turing condition of this system is determined by a linear stability analysis ► The system needs strong regulatory interactions of molecules for the Turing condition ► Pattern formation by the system is examined in fixed or expanding 2D space ► We use this system to explain pattern formation in the shoot meristem ofplants
