Application of surface-enhanced resonance Raman spectroscopy to chlorophyll and chlorophyll derivatives
<p>Chlorophylls and chlorophyll derivatives are fundamental components of green plants and are directly involved in light trapping and electron transfer during photosynthesis. In Sections 1-3 surface-enhanced resonance Raman spectroscopy (SERRS) has been employed to obtain Raman vibrational spectra …

Biochemische Untersuchungen an der Chlorophyll Synthase aus Avena sativa
Die Chlorophyll Synthase ist ein äußerst hydrophobes Transmembranprotein und sitzt in der Thylakoidmembran im Chloroplasten. Sie verestert Chlorophyllid und Phytylpyrophosphat zu Chlorophyll. In dieser Arbeit sind Untersuchungen zur Lage der Transmembranbereiche, zum aktiven Zentrum bzw. zu …

Validation and application of the MERIS Terrestrial Chlorophyll Index.
… operational product called the MERlS Terrestrial Chlorophyll Index (MTCI). The MTCI is related to the position of the red edge in vegetation spectra and can be used to estimate the chlorophyll content of vegetation. The MTCI therefore provides a powerful product to monitor phenology, stress and …

Computational analysis of upstream regulatory elements regulating plant chlorophyll degradation
"Chlorophyll is a vital compound in photosynthesis in plants and as such both its biosynthesis and degradation are tightly regulated. Disruption of the regulatory pathway for chlorophyll breakdown by exposure to cold temperature episodes in canola seed is the basis of the economically significant …

Chlorophyll diagenesis in the water column and sediments of the Black Sea
This thesis examines the degradation pathways of chlorophyll in the Black Sea water column and sediments. Measurements are made of total chlorophyll in sediment traps from two locations and depths in the water column, and at two locations in surface sediments. Individual chlorophyll degradation …
