Control by light of hypocotyl growth in de-etiolated mustard seedlings : II. Sensitivity for newly-formed phytochrome after a light to dark transtition.

abstract：:Light causes growth of dicotyledonous leaves by stimulating proton efflux, cell wall acidification and loosening, and solute accumulation for turgor maintenance. For cells still undergoing cell division at the base of expanding tobacco ( Nicotiana tabacum L. cv. Xanthi) leaves, light-stimulated growth depends on K+ up...
