It is generally accepted that early chlorophytes gave rise to the plants. Cells of the Chlorophyta contain organelles called chloroplasts in which photosynthesis occurs; the photosynthetic pigments chlorophyll a and chlorophyll b, and various carotenoids, are the same as those found in plants and are...
Regression analysis of reflectance (R rs) ratio and absorption coefficient of phytoplankton (a ph) indicates a close correlation between them, which means that it is possible to retrieve absorption coefficient of phytoplankton using ocean color remote sensing data in optically complex coastal waters....
Thus, the authors deduced that ROS produced during the treatments were responsible for the pigment degradation. Furthermore, it was also hypothesized that the application of plasma produced partial denaturation of enzymes, which may have slowed down chlorophylls catabolism operated by enzymes such as ...
Perhaps, you’ve been told that the plants are green because of their green pigment. But have you wondered, of all the colors, why green? Before we try to figure out the answer to that, let’s define pigment. In essence, a pigment means a coloring material; it is a dye, a paint....
For measuring plant stress responses, it is claimed that the Fv/Fm ratio is a more reliable parameter than the Fv/F0 [8]. Its optimal value is approximately 0.830, which is observed in most of the healthy plants [7], however in stressed plants, Fv/Fm values decrease, indicating possible...
Chlorophyll is a very important pigment involved in photosynthesis, while plant acyl-CoA biosynthesis is derived from plastid-localized fatty acids (FAs). Until now, the regulation of the acyl-CoA pathway for chlorophyll biosynthesis is still unknown. He
Chlorophyll is found in plants, algae, cyanobacteria, protists, and a few animals. Although chlorophyll is the most common photosynthetic pigment, there are several others, including the anthocyanins. The word "chlorophyll" comes from the Greek wordschloros, which means "green", andphyllon, which...
This means that models are trained on log-transformed (base 10) in situ measured Chla, and the conditional distribution of log Chla is then normally distributed with a mean (μ), which is a function of explanatory variables, and a fixed standard deviation (σ). Existing OC algorithms use a...
The results are not inconsistent with the assumption that the true quantum requirement for the photochemical transport of 1 electron is 1 for each of the two pigment systems. 4. 4. A new "differential" flow attachment for a fluorescence apparatus was constructed by means of which small changes...
Then, they focused on refining the design of the light-guiding layer, the first structure light encounters as it comes back from the leaf. This is a possible source of error as light naturally deviates with the type and width of material it goes through. The team found that a light-guidin...
