Observations on the mechanism of light harvesting in algae: Light assimilation is of utmost importance to living creatures. Indeed , all matter is produced by lightwaves slowing down to become matter- wave /particle/wave -it is a with a keeness that I say now that effects of various means to cover our oceans, blanketing them with ( space algae) chemtrails, oil, jet fuel,ect. is meant as a means to deprive the oceans and water of sunlight and interfere with the natural process of assimilating light and producing electron charges in the air which produce lightening and storms hwhich maintain the ionosphere and magnetic feild of the Earth...( as I understand it). Algae needs the sunlight to produce and it needs good growing conditions to be stable... "Plants, green algae and cyanobacteria perform photosynthetic conversion of sunlight into chemical energy in a permanently changing natural environment, where the efficient utilization of light and inorganic carbon represent the most critical factors. Photosynthetic organisms have developed different acclimation strategies to adapt changing light conditions and insufficient carbon source supply in order to survive and to assure optimal growth and protection. This thesis provides further insights into the molecular mechanisms of the acclimation response of the green algae Chlamydomonas reinhardtii. An important acclimation mechanism to altering light conditions involves the posttranscriptional regulation of the nuclear-encoded photosystem II (PSII)-associated lightharvesting complex (LHCII) genes via cytosolic translational control mediated through the RNA-binding protein NAB1. In the active state, NAB1 represses the cytosolic translation of LHCII mRNAs by sequestration into translational silent messenger ribonucleoprotein complexes (mRNPs). The overexpression of NAB1 decreases LHCII protein amount whereas NAB1 knockout leads to an increased level of LHCII proteins. Consequently, NAB1 is part of a control system regulating the size and composition of the LHCII complex at the posttranscriptional level. The repressor activity of this specific factor is controlled by two posttranslational modifications: i) by methylation of arginines in the glycine-arginine rich (GAR) motif of the protein, ii) by the thiol status of two C-terminal cysteines. This work provides evidence that arginine methylation represents a slowly reacting modulator, which is required for the maintenance of the repressor activity of NAB1 and is responsive to the availability of light. At the same time, cysteine modification is regarded as the fine-tuning mechanism that dynamically responds to changes in the cytosolic redox-state. Moreover, the observations suggest that the regulation via arginine methylation operates independently from cysteine-based redox control, with its extent strongly depending on the growth conditions. The high methylation state is found under photoautotrophic, and the low methylation state under heterotrophic growth conditions. Photosynthetic performance is also dependent on inorganic carbon (Ci) supply, because the light-harvesting capacity and the utilization of captured energy have to be balanced. The insufficient Ci-availability can be compensated by diverse organic carbon sources" ...From the work of Wilhelm Reich, which I am still reading... We need to now empower the Earth to produce this algae to counteract the toxic effects. We need to restore the water back to its' original state. Many of you here know I believe I may have a solution- which must be further tested, but please let us not ignore this very important bio-function. Our lives depend on it. molecular-mechanism-adjustment-phototrophic-light-harvesting.pdf
The Ocean's Living Carbon Pumps October 23, 2014 Satellite image showing a patch of bright waters associated with a bloom of phytoplankton in the Barents Sea off Norway.

"When we talk about global carbon fixation -"pumping" carbon out of the atmosphere and fixing it into organic molecules by photosynthesis - proper measurement is key to understanding this process. By some estimates, almost half of the world's organic carbon is fixed by marine organisms called phytoplankton - single-celled photosynthetic organisms that account for less than one percent of the total photosynthetic biomass on Earth. Dr. Assaf Vardi, a marine microbiologist in the Weizmann Institute's Plant and Environmental Sciences Department, and Prof. Ilan Koren, a cloud physicist, and Dr. Yoav Lehahn, an oceanographer, both from the Earth and Planetary Sciences Department, realized that by combining their interests, they might be able to start uncovering the role that these minuscule organisms play in regulating the carbon content of the atmosphere. Tiny as they are, phytoplankton can be seen from space: They multiply in blooms that can reach thousands of kilometers in area, coloring patches of the ocean that can be tracked and measured by satellites." snip http://www.spacedaily.com/reports/The_Oceans_Living_Carbon_Pumps_999.html
