Abstract
In needles of Scots pine the galactolipid content is similar in summer and in winter needles, while the molar ratio between monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG) is approx. 2.0 in summer and 0.8 in winter (Selstam, unpublished). The low ratio of MGDG to DGDG found in winter needles of Scots pine and other extremely frost resistant plants may be an important characteristic of thylakoid membrane acclimated to freezing temperatures since MGDG and DGDG have very different physicochemical properties.
