Biosynthesis, accumulation and emission of carotenoids, alpha-tocopherol, plastoquinone, and isoprene in leaves under high photosynthetic irradiance.

abstract：:In many ways, the 1963 conference at Airlie House was an unusual event. The meeting convincingly demonstrated that photosynthetic research, previously reported mostly at conferences of botany and/or plant physiology, had become an independent and important field of biological research. New techniques had been develope...
