Chlorophyll Breakdown in Senescent Leaves.
The biosynthetic pathway of Chl, probably the most important pigment in the biosphere, has been studied in considerable detail and is mentioned in plant physiology textbooks. Oddly enough, however, the breakdown of Chl is barely mentioned. Yet, as pointed out by Hendry et al. (1987), an estimated one billion tons of Chl are broken down every year, seemingly without leaving a trace. The only enz...
متن کاملChlorophyll breakdown in senescent Arabidopsis leaves. Characterization of chlorophyll catabolites and of chlorophyll catabolic enzymes involved in the degreening reaction.
During senescence, chlorophyll (chl) is metabolized to colorless nonfluorescent chl catabolites (NCCs). A central reaction of the breakdown pathway is the ring cleavage of pheophorbide (pheide) a to a primary fluorescent chl catabolite. Two enzymes catalyze this reaction, pheide a oxygenase (PAO) and red chl catabolite reductase. Five NCCs and three fluorescent chl catabolites (FCCs) accumulate...
متن کاملChlorophyll regulates accumulation of the plastid-encoded chlorophyll proteins P700 and D1 by increasing apoprotein stability.
Chlorophyll protein accumulation in barley (Hordeum vulgare L.) chloroplasts is controlled posttranscriptionally by light-induced formation of chlorophyll a. The abundance of translation initiation complexes associated with psbA, psaA, and rbcL mRNAs was measured using extension and inhibition analysis in plants grown in the dark for 4.5 d and then illuminated for up to 16 h. Light-induced accu...
متن کاملEffect of chloramphenicol on chlorophyll synthesis of bean leaves.
Chloramphenicol has been found to inhibit the decrease in lag phase of chlorophyll accumulation in bean leaves that is brought about by a brief illumination followed by a prolonged dark period. The effectiveness of chloramphenicol depends on time of application. It is more effective when applied at the beginning of the dark period than at the end.
