[1] Soil moisture control on evapotranspiration is poorly understood in ecosystems experiencing seasonal greening. In this study, we utilize a set of multi-year observations at four eddy covariance sites along a latitudinal gradient in vegetation greening to infer the ET-q relation during the North American monsoon. Results reveal significant seasonal, interannual and ecosystem variations in th...

Dark-grown etiolated cells of Cyanidium caldarium mutant III-C lacking >/=99% of their normal chlorophyll content and inactive for photosynthesis were greened in continuous light. Measurements of oxygen evolution and fluorescence kinetics indicate that during greening: (a) the photosystem II (PSII) antenna containing between 30 and 40 chlorophyll a per center undergoes little change in size fro...

The northern latitudes have warmed by about 0.8 C since the early 1970s, but not all areas have warmed equally. Eurasia shows an overall warming trend, while North America exhibits warming at a lower rate and even a slight cooling trend during the last 50 years in the Eastern USA. We analyzed a recently developed satellite normalized di erence vegetation index (NDVI) data set (July 1981 to Dece...

Changes in the amount of P700-chlorophyll a protein complex, plastocyanin, and cytochrome b(6)/f complex during greening of pea (Pisum sativum L.), wheat (Triticum aestivum L.), and barley (Hordeum vulgare L.) leaves were analyzed by an immunochemical quantification method. Neither subunit I nor II of P700-chlorophyll a protein complex could be detected in the etiolated seedlings of all three p...

We combined a satellite-derived Leaf Area Index (LAI) dataset and a gridded climate dataset to analyse trends in vegetation activity and their correlation with climate variability in China between 1982 and 1998. Vegetation activity over the growing season increased 11.03% in China during the 17-year period, which is broadly consistent with the greening trend in the northern high latitudes in Eu...

The proteins of prolamellar bodies of etioplasts and of thylakoid membranes of greening and mature chloroplasts from Zea mays were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Three classes of proteins were distinguished: those present in etioplasts and disappearing during greening, those absent in etioplasts and appearing during greening, and those present in both et...

Von Maj Munch Andersen he recent rise of greening as a corporate issue forms a part of what some environmental researchers see as the emergence of a new green techno-economic paradigm (1). The greening process is seen as revolutionary in character, entailing a paradigm shift resulting in major cognitive and technological changes. This paradigm change is expected to have thorough structural effe...

ELIPs (early light-induced proteins) are thylakoid proteins transiently induced during greening of etiolated seedlings and during exposure to high light stress conditions. This expression pattern suggests that these proteins may be involved in the protection of the photosynthetic apparatus against photooxidative damage. To test this hypothesis, we have generated Arabidopsis (Arabidopsis thalian...

The flora of vacuum-packaged dark, firm, dry meat included thred organisms not usually found on vacuum-packaged meat, Yersinia enterocolitica, Enterobacter liquefaciens, and Alteromonas putrefaciens. Y. enterocolitica did not affect the meat quality. Production of spoilage odors by E. liquefaciens could be prevented by addition of glucose or citrate to the meat. Greening of meat could be preven...
