Chlorophyllase activities and chlorophyll degradation during leaf senescence in non-yellowing mutant and wild type of Phaseolus vulgaris L
Introduction Leaf senescence involves degradation of proteins, The activities of chlorophyllase, contents of pigments chlorophylls, nucleic acids, membranes, and subsequent including chlorophyll a and b, chlorophyllide a and b, transport of some of the degradation products to other and phaeophorbide a during leaf senescence under parts of the plant (Buchanan-Wollaston, 1997; Noodén, low oxygen ...
متن کاملRegulated Chlorophyll Degradation in Spinach Leaves during Storage
Degradation of chlorophyll in spinach (Spinacia olearacea L. cv. Hybrid 612) appeared to be regulated through the peroxidase-hydrogen peroxide pathway, which opens the porphyrin ring, thus resulting in a colorless compound. This conclusion was arrived at from the analysis of chlorophylls (Chls) and their metabolizes by HPLC and of enzyme activities catalyzing the degradative reactions. Chls dec...

15 صفحه اولMechanism of glycolate transport in spinach leaf chloroplasts.
The incorporation of (14)CO(2) into glycolate by intact spinach leaf (Spinacia oleracea L. var. Kyoho) chloroplasts exposed to (14)CO(2) (NaH(14)CO(3), 1 millimolar) in the light was determined as a function of O(2) concentrations in the reaction media. A hyperbolic saturation curve was obtained, apparent K(m) (O(2)) of 0.28 millimolar, indicating that glycolate is produced predominantly by rib...
