Arrest of chlorophyll accumulation prior to anthocyanin formation in Euphorbia pulcherrima

Kannangara, C Gamini and Hansson, Mats LU (1998) In Plant Physiology and Biochemistry 36(12). p.843-848
Abstract
Euphorbia pulcherrima Klotz plants exposed to short days (11 h light/13 h dark) for a period of eight weeks, developed flowers and a red canopy consisting of bracts and few true leaves. Plants maintained for three weeks under short day conditions, failed to produce flower primordia or a red canopy in the following 5 weeks in continuous light. Between the 4th and 5th short day week, the youngest leaves began to accumulate anthocyanin and turned red while the apical meristems differentiated into flower primordia. Chlorophyll accumulation ceased at the onset of anthocyanin synthesis and the protein content per unit leaf area declined. mRNA for glutamyl-tRNAGlu synthetase (EC 6.1.1.17) and glutamyl-tRNAGlu reductase also declined during this...

Euphorbia pulcherrima Klotz plants exposed to short days (11 h light/13 h dark) for a period of eight weeks, developed flowers and a red canopy consisting of bracts and few true leaves. Plants maintained for three weeks under short day conditions, failed to produce flower primordia or a red canopy in the following 5 weeks in continuous light. Between the 4th and 5th short day week, the youngest leaves began to accumulate anthocyanin and turned red while the apical meristems differentiated into flower primordia. Chlorophyll accumulation ceased at the onset of anthocyanin synthesis and the protein content per unit leaf area declined. mRNA for glutamyl-tRNAGlu synthetase (EC 6.1.1.17) and glutamyl-tRNAGlu reductase also declined during this period. Western blot analysis revealed a loss of glutamyl-tRNAGlu reductase, glutamate 1-semialdehyde (EC 5.4.3.8) and the Mg-chelatase subunits, Olive and CH42, in the last 2 to 4 weeks of the photoperiod.
