Biosynthesis of chlorophyll b

Canadian Journal of Biochemistry, 1977
Using [14C]chlorophyll a derived from a mutant of wheat lacking chlorophyll b, spinach thylakoids from very young leaves and cucumber thylakoids of irradiated, etiolated cotyledons convert chlorophyll a to b with apparent yields of 19% and 5%, respectively.

Simultaneous determination of chlorophyll a and chlorophyll b by derivative spectrophotometry

Analytical and Bioanalytical Chemistry, 2004
Chlorophyll a (Chl a) and chlorophyll b (Chl b) plant pigments, which are important in the food industry and are beneficial as environmental pollution indicators, have been extracted with a novel solvent mixture (1:1 v/v acetone-propanol) not containing chloroform and simultaneously determined by first-derivative spectrophotometry.

Conversion of Chlorophyll b to Chlorophyll a by Isolated Cucumber Etioplasts

Archives of Biochemistry and Biophysics, 1993
Chlorophyllide b was converted to chlorophyll a when incubated with cucumber etioplasts in the presence of phytol, ATP, and MgCl2. Chlorophyll a was identified by retention time on HPLC, absorption, fluorescence, and excitation spectra. It is suggested that the interconversion of chlorophyll a and b plays a significant role in the establishment of the ...

Biosynthesis of chlorophyll b and the chlorophyll cycle

Photosynthesis Research, 2002
Recent progress in the knowledge of chlorophyll b biosynthesis from chlorophyllide a and reduction of chlorophyll b to chlorophyll a is described. The minireview includes a description of the enzymes involved in these reactions and, where appropriate, of the genes encoding these enzymes.

Chlorophyll a/b binding-specificity in water-soluble chlorophyll protein

Nature Plants, 2018
We altered the chlorophyll (Chl) binding sites in various versions of water-soluble chlorophyll protein (WSCP) by amino acid exchanges to alter their preferences for either Chl a or Chl b. WSCP is ideally suited for this mutational analysis since it forms a tetrameric complex with only four identical Chl binding sites.

Remote Sensing of Chlorophyll a, Chlorophyll b, Chlorophyll a+b, and Total Carotenoid Content in Eucalyptus Leaves

Remote Sensing of Environment, 1998
Abstract Algorithms based on reflectance band ratios have been developed for the remote estimation of chlorophyll a , chlorophyll b , chlorophyll a+b , and total carotenoid content of Eucalyptus leaves. Reflectance spectra over the 400–2500 nm range with a spectral resolution of 2 nm and the content of chlorophylls a , b , a+b , and total ...
