✦ Synopsis

Mixotrophic cell cultures of Chenopodium rubrum were found to synthesize 5 to 33 times more monogalactosyldiacylglycerols and 5 to 16 times more digalactosyldiacylglycerols than heterotrophic ones, The monogalactosyldiacylglycerols and digalactosyldiacylglycerols from mixotrophic cultures contained higher levels of linolenic acid as compared to heterotrophic cultures. It is concluded that the active synthesis of these galactolipids with high levels of constituent linolenic acid is associated with the onset of photosynthesis in plant cell cultures, as is the case in intact plants.

Lipids from callus cultures and suspension cultures of higher plants constitute 5 to 8% of the dry tissue's weight. The predominant lipid classes are the sterols, steryl esters, steryl glycosides and esterified steryl glycosides. Considerable amounts of a variety of sterylglycolipids, whose structur

Rape (Brassiea napus cv. Target) and turnip rape (Brassica campestrb cv. Echo) were grown as callus cultures. The lipids isolated from these cultures were found to contain substantial amounts of monogalactosyl diglycerides, digalactosyl diglycerides, and phosphatidyl glycerol, whereas sulfolipids, e

## Abstract The pattern of lipid classes in plant tissue cultures is similar to that in non‐photosynthetic plants and plant organs, mono‐galactosyl diglycerides, digalactosyl diglycerides, sulfoquinovosyl diglycerides and phosphatidyl glycerol being very low or absent. In contrast, photosynthetic p
