Cyanidin 3-O-b-D-glucoside (C3G) of a typical anthocyanin pigment could lower the serum thiobarbituric acid-reactive substance concentration and increase the oxidation resistance of the serum to lipid peroxidation in rats [52]. In vitro enzymatic and non-enzymatic polyunsaturated fatty acid per oxidation was significantly inhibited in a dose-dependent manner by anthocyanin [53], a deep-red color pigment from carrot cell cultures. 

Individual measurement of all five tryptophan pathway enzymes have been reported from tobacco and carrot cell cultures, wheat, corn, and peas (Widholm, 1973 Singh and Widholm, 1974 Hankinsa/, 1976). The relative amounts of the enzymes assayed in vitro differ with the various sources. However, Singh and Widholm (1974) reported extractable quantities of each enzyme in wheat, regardless of the tissue source or plant age, sufficient to synthesize the amount of tryptophan present within the same tissue in 48 h. No in vitro aggregation of any of the tryptophan branch enzymes was ob-...

In a recent review Cote and Crain [5] have pointed to three phenomena which they thought particularly convenient to study the physiological role of phosphoinositides in plants. These were 1) the turgor changes in stomatal guard cells, paiticulaiiy after a treatment with abscisic acid which provokes the closure of stomata, 2) the osmotic stress in Dunaliella salina or carrot cell cultures and 3) the deflagellation of Chlamydomonas reinhardtii after exposure of the alga to acid pH, elevated temperature or ethanol. Nevertheless the rates of apparition of inositolphosphates after stimulation have been found very different in various plant tissues (from 30 sec to 30 min).
