Growth and anthocyanin accumulation in carrot cell suspension cultures growing in fructose, glucose, or their mixtures

Carrot suspension cultures have been grown on glucose, fructose, and mixtures of these two sugars and the effects of these sugars on growth and anthocyanin accumulation measured. Several parameters of growth decrease with increasing glucose in the medium. The anthocyanin accumulated remains relative...

Description
Summary:Carrot suspension cultures have been grown on glucose, fructose, and mixtures of these two sugars and the effects of these sugars on growth and anthocyanin accumulation measured. Several parameters of growth decrease with increasing glucose in the medium. The anthocyanin accumulated remains relatively low and constant until the glucose exceeds 50% of the sugar, when the anthocyanin accumulation increases with increased glucose. The data suggest that glucose and fructose are metabolized differently in these carrot cultures despite the interconversion of their 6‐phosphates in glycolysis. Ways in which the metabolism of these sugars might differ are discussed, as is the possibility of increasing the accumulation of anthocyanin by alterations in the way these sugars are made available to the cultures.
