THE DEVELOPMENT OF CHLOROPLASTS IN ROOT MERISTEMATIC TISSUE OF

摘要: Proplastids of the meristematic region roots rye, Secale cereale, seedlings can be induced to develop into chloroplasts after a lengthy period continuous exposure light. The transformation involves formation prolamellar bodies which eventually become source membrane material for organization granal and intergranal thylakoids. process is also accompanied by two-step increase in number plastidial ribosomes coincides with extension intraplastidial system progressive accumulation photosynthetic pigments development Hill reaction activity. Overall mature root tissue compare well both structurally functionally those from leaves same plant.
