Pigment Accumulation During Growth and Development at Low Temperature
Abstract
Recently, it has been shown that the thylakoid membranes from winter rye (Secale cereale L. cv Puma) undergo significant structural and functional alterations upon growth and development at cold-hardening temperatures (Huner et al 1983, Elfman et al 1983, Huner, Hopkins 1983) even though the basic composition (i.e. polypeptide, pigment, lipid and fatty acid components) remained unchanged. We hypothesized that one possibility which could account for this apparent discrepancy was that although the basic components of cold-hardened (RH) and non-hardened (RNH) thylakoids were similar, the manner in which they are assembled into functional units may be different. To determine the validity of this hypothesis, we initiated an investigation into the kinetics of thylakoid membrane assembly by monitoring the greening process in winter rye at normal (20°C) and cold-hardening temperatures (5°C).
