Isolation and characterization of a urobilinogenoidic chlorophyll catabolite from Hordeum vulgare L.
نویسندگان
چکیده
A new type of chlorophyll catabolite was isolated from extracts of de-greened primary leaves of barley (Hordeum vulgare cv. Lambic). Its constitution was elucidated by one-dimensional and two-dimensional [(1)H,(13)C]-homo- and heteronuclear NMR spectroscopic techniques and by high resolution mass spectroscopy. The isolated catabolite, a water-soluble, colorless, and nonfluorescent linear tetrapyrrole, resembles urobilinogen in which one of the propionic side chains forms a five membered isocylic ring system, indicating its origin from the chlorophylls.

Chlorophyll b to chlorophyll a conversion precedes chlorophyll degradation in Hordeum vulgare L.
This study reveals by in vivo deuterium labeling that in higher plants chlorophyll (Chl) b is converted to Chl a before degradation. For this purpose, de-greening of excised green primary leaves of barley (Hordeum vulgare) was induced by permanent darkness in the presence of heavy water (80 atom % (2)H). The resulting Chl a catabolite in the plant extract was subjected to chemical degradation b...
متن کاملA Dioxobilane as Product of a Divergent Path of Chlorophyll Breakdown in Norway Maple**
Chlorophyll breakdown is a hallmark of leaf senescence and a major contributor to the emergence of the fall colors. Strikingly, essential pieces of the puzzle of this biological phenomenon have been solved only within the last two decades. A breakthrough was the identification and structure elucidation of a colorless tetrapyrrolic chlorophyll catabolite, thereafter named Hv-NCC-1. The further c...
متن کاملEvaluation of cement dust effects on soil microbial biomass and chlorophyll content of Triticum aestivum L. and Hordeum vulgare L.
ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
متن کاملIsolation and Characterization of a New Minor Chlorophyll a/b-Protein Complex (CP24) from Spinach.
We have identified a new minor chlorophyll a/b-protein complex in the thylakoid membranes of spinach (Spinacia oleracea L.), which migrates as a green band below CPII on mildly denaturing polyacrylamide gels. This complex, designated CP24, was isolated from octyl glucoside/sodium dodecyl sulfate solubilized spinach grana membrane fractions by preparative gel electrophoresis and has been charact...
متن کاملFurther Chemical and Morphological Characterization of Chloroplast Membranes from a Chlorophyll b-less Mutant of Hordeum vulgare.
A comparative study of peptide composition and freeze-fracture morphology of chloroplast membranes from a chlorophyll b-less mutant and a normal barley plant (Hordeum vulgare L.) is reported in this work. Using a high resolution, discontinuous sodium dodecyl sulfate-acrylamide gel electrophoretic system, we show that the mutant chloroplast membranes not only completely lack the 25-kilodalton pe...
