Factors influencing the stable carbon isotopic composition of suspended and sinking organic matter in the coastal Antarctic sea ice environment [PDF]
A high resolution time-series analysis of stable carbon isotopic signatures in particulate organic carbon (δ<sup>13</sup>C<sub>POC</sub>) and associated biogeochemical parameters in sea ice and surface waters provides an

Stay-green regulates chlorophyll and chlorophyll-binding protein degradation during senescence [PDF]
Stay-green mutants are delayed in leaf senescence and have been identified from different plant species, including many crops. Functional stay-greens have the potential to increase plant productivity. In cosmetic stay-greens, however, retention of chlorophyll during senescence is uncoupled from a decline of photosynthetic capacity in these mutants. For

Abstract Chlorophyll (Chl) serves a number of essential functions, capturing and converting light energy as a component of photosystem supercomplexes. Chl degradation during leaf senescence is also required for adequate degeneration of chloroplasts and salvaging of nutrients from senescent leaves.

The response of diatom central carbon metabolism to nitrogen starvation is different from that of green algae and higher plants [PDF]
The availability of nitrogen varies greatly in the ocean and limits primary productivity over large areas. Diatoms, a group of phytoplankton that are responsible for about 20% of global carbon fixation, respond rapidly to influxes of nitrate and are ...

Changes in chlorophyll (Chl) degrading enzyme activities were determined to clarify the pathway of Chl degradation in stored broccoli (Brassica oleracea L.) florets. Chl content in the florets decreased greatly after 2 days of storage at 15°C, whereas at 3°C they showed almost no change during storage.

Identification of genes associated with chlorophyll accumulation in flower petals. [PDF]
Plants have an ability to prevent chlorophyll accumulation, which would mask the bright flower color, in their petals. In contrast, leaves contain substantial amounts of chlorophyll, as it is essential for photosynthesis. The mechanisms of organ-specific

Degradation of Chlorophyll Luminescence in Plants
The chlorophyll photoluminescence intensity degradation of Vallisneria spiralis L. water plant is studied. It is shown that the degradation curve is rather well described by a sum of two hyperbolic functions. The rate of intensity degradation reduces at low temperatures.
