Cold acclimation of the Arabidopsis dgd1 mutant results in recovery from photosystem I-limited photosynthesis [link]Paper  doi  abstract   bibtex   
We compared the thylakoid membrane composition and photosynthetic properties of non- and cold-acclimated leaves from the dgd1 mutant (lacking \textgreater90% of digalactosyl–diacylglycerol; DGDG) and wild type (WT) Arabidopsis thaliana. In contrast to warm grown plants, cold-acclimated dgd1 leaves recovered pigment-protein pools and photosynthetic function equivalent to WT. Surprisingly, this recovery was not correlated with an increase in DGDG. When returned to warm temperatures the severe dgd1 mutant phenotype reappeared. We conclude that the relative recovery of photosynthetic activity at 5°C resulted from a temperature/lipid interaction enabling the stable assembly of PSI complexes in the thylakoid.
