Remember, chlorophylls and carotenoids are hydrophobic or nonpolar and will dissolve in less polar solvents, whereas anthocyanins are extractable and soluble in more polar solvents like water. What are the 4 types of chlorophyll? There are four types of chlorophyll: chlorophyll a, found in all hig...
What is a cathode ray? What is the absolute threshold of brightness? What is chlorophyll? What is a dispersion medium? What is refraction during an eye exam? What is the refractive index of a glass slab? What is carbon film tint?
Q Bo,AJ Gabric,PA Matrai - 《Polar Biology》 被引量: 66发表: 2006年 Diatoms and the Ecological Conditions of Their Growth in Sea Ice in the Arctic Ocean The chlorophyll content of this layer is 100 times more than that of the surrounding sea waters; this has led to a hypothesis that ...
oceanica that the level of Chlorophyll a depends on carotenoids particularly violaxanthin, as Chlorophyll a was well-correlated with carotenoids including violaxanthin when carotenoids changed responding to NoZEP manipulation (Additional file 1: Fig. S10). The level of polar membrane lipids is also ...
Phylogenetic relation- ships between Glaucocystis species were examined based on analyses of the concatenated sequences (2,211 base pairs) of the photosystem I P700 chlorophyll a apoprotein A2 (psaB) gene (1,461 base pairs) and the photosystem II P680 chlorophyll a apoprotein D1 (psbA) gene...
(SIA; solid) and sea ice retreat (SIR; dashed).bChange in the average proportion of total chlorophyll-a(Chl-a) concentration attributed to each season from 2001–2010 to 2011–2020 in the WAP (regions DRA, BRS and GES). Spring: September-November, Summer: December-February, Autumn: ...
The transcription of apo-phycoerythrin was found to be downregulated in green mutant strain, but the expression of chlorophyll–protein complex increased. The optical activation of phycoerythrin required the binding of apo-phycoerythrin to phycoerythrobilin. Similarly, genes related to the synthesis of ...
Daily changes in the chlorophyll a concentration in phytoplankton are often explained by alternation of low and high illumination intensities or cellular circadian rhythms [2, 8, 9]. Here, we focused on the short-period daily changes in the chlorophyll a concentration in the estuarial pelagic ...
chlorophyll index, and biochemical structure of basil were analyzed at 90th time. The (Chlorella vulgaris) + (Serendipita indica) (MI + F) therapy increased chlorophyll index by 61.7% (SPAD) in comparison to manage. (Chlorella vulgaris) had the best growth hormones, including GA3 at 158.2 ppb...
1.67 m (core E), sea ice thickness was very low for spring conditions, but is in agreement with the observed reduction of sea ice in the Fram Strait36and Central Arctic38. The highest concentrations of ice algal biomass, as indicated by chlorophyll a, were mostly found in the lowest ...
