“…These daily patterns are a good indication of a rapid turnover of the pigments in the natural environment. Rapid turnover of chlorophyll has also been shown in algae (35,162,163), and it was larger than that of higher plants (164). Thus the excess of light could reduce the amount of pigments in the natural environment in highly exposed algae (48,54).…”

“…Some measurements of the turnphyllides, the immediate precursors of the light-over of chlorophyll and precursors in etiolated and requiring step at NADPH-protochlorophyllide oxi-greening tissues suggest that these catabolic systems doreductase (POR). This tells us that the section of are surprisingly active (Stobart & Hendry, 1984; the biosynthetic pathway between ALA dehydratase Hendry & Stobart, 1986). …”

SUMMARY The metabolism of chlorophylls and related tetrapyrroles directly influences, and is influenced by, the proteins and cell structures with which they are associated. During net accumulation, de‐greening and at the steady state chlorophyll and its derivatives are important elements in the post‐translational regulation of the expression of genes for chloroplast proteins. At the same time, they represent potential photodynamic hazards against which green cells need to have protective mechanisms. This review deals with genetic, chemical and environmental perturbations of chlorophyll biosynthesis that impact on protein stability, membrane organization and susceptibility to photodamage. NADPH‐protochlorophyllide oxidoreductase is considered in detail as a pigment– protein regulating, and regulated by, chlorophyll metabolism. The question of the extent and significance of chlorophyll turnover at the steady state is addressed, with particular emphasis on the dynamics of the photosystem II reaction centre. The pathway of chlorophyll catabolism is described, along with its interrelationship with protein mobilization in chloroplast senescence. Finally, the structural basis of pigment‐protein interaction and stability is examined, and the discussion ends by expressing some general thoughts about the control of protein lifetimes in the living cell.

“…Vol 105, 1994 and barley leaves is between 35 and 77 h (Stobart and Hendry, 1984;Hendry and Stobart, 1986). During senescence, because of higher activity of Chl-catabolizing enzymes and especially that of chlorophyllase (Klein and Vishniac, 1961;McFeeters et al, 1971;Thimann, 1980;Terpstra, 1981), the life span of a Chl molecule is expected to decrease.…”
