Light and plant development : [proceedings of the 22nd University of Nottingham Easter School in Agricultural Science, held at Sutton Bonington from april 1975

Light and Plant Development presents the Proceedings of the 22nd University of Nottingham Easter School in Agricultural Science. It discusses the spectral sensitivity of inhibition of flowering by light. It addresses the action spectrum for leaf enlargement and stem growth inhibition. Some of the topics covered in the book are the nature of the blue light photoreceptor in higher plants and fungi; re-examination of photochemical properties and absorption characteristics of phytochrome using high-molecular-weight preparations; and intermediates in the photoconversion of phytochrome. The high irradiance reaction is fully covered. The physiological evidence and localised responses, intracellular localisation and action of phytochrome are discussed in detail. The text describes in depth the immunological visualisation of phytochrome. The fractionation procedures and terminology are presented completely. A chapter is devoted to the photocontrol of enzyme levels. Another section focuses on the ribosomal RNA synthesis in developing leaves. The book can provide useful information to botanists, chemists, students, and researchers.
