Plants produce an immensely broad array of lipids, including components of membrane bilayers, storage oils, protective coatings, the photosynthetic machinery and signal transduction systems. The concentration of acetyl-COA in chloroplasts is only 30 to 50 BM (Post-Beittenmiller et al., 1992), which is sufficient to supply the needs of fatty acid synthesis for only a few seconds. Here, we demonstrate that Arabidopsis (Arabidopsis thaliana) basal autophagy contributes to triacylglycerol (TAG) synthesis, whereas inducible autophagy contributes to LD degradation. In higher plants, it was thought that CGG encoded for tryptophan and not arginine; however, the codon in the processed RNA was discovered to be the UGG codon, consistent with the standard genetic code for tryptophan.
