Protein phosphorylation landscape in photosystem I of the desert algae Chlorella sp

ABSTRACT: The regulation of photosynthesis in response to varying light conditions is primarily controlled through the phosphorylation of thylakoid proteins. This process is most extensively studied in the context of the phosphorylation of photosystem II (PSII) and light-harvesting complex II (LHCII) subunits. However, there is comparatively less understanding of the changes induced by light stress in photosystem I and light-harvesting complex I (LHCI). In this study, we examined the alterations in protein phosphorylation of PSI-LHCI in Chlorella ohadii, an extremely light-tolerant desert green alga, when grown under low light (LL) and high light (HL) conditions.

The phosphorylation of photosystem II (PSII) and its antenna (LHCII) proteins has been studied, and its involvement in state transitions and PSII repair is known. Yet, little is known about the phosphorylation of photosystem I (PSI) and its antenna (LHCI) proteins. Here, we applied proteomics analysis to generate a map of the phosphorylation sites of the PSI-LHCI proteins in Chlorella ohadii cells that were grown under low or extreme high-light intensities (LL and HL). Furthermore, we analyzed t ...[more]

Density Transfer Data for Lachancea waltii DNA Replication Profile

Project description:Array data detailing the progression of DNA replication in the yeast Lachancea waltii. L. waltii cells were pregrown in heavy isotope medium and synchronized at early S phase. They were then released into normal medium, wherein DNA replication proceeds. Replicated DNA molecules are thus of heavy-light (HL) composition as compared to unreplicated molecules, which are heavy-heavy (HH). 4 time points were taken and the percent of heavy-light DNA was determined at each time point. The heavy-heavy and heavy-light DNA molecules were separated by ultracentrifugation, differentially labeled, and hybridized to a genomic array for L. waltii. The array thus shows the progression of DNA replication.

Comparison of the photoprotection mechanism in Chlorella Ohadii and Chlamydomonas reinhardtii

Project description:Light is the driving force of photosynthesis. However, excessive light can be harmful. Photoinhibition, or lightinduced photodamage, is one of the key processes limiting photosynthesis. When the absorbed light exceeds the amount that can be dissipated by photosynthetic electron flow and other processes, damaging radicals are formed that mostly inactivate photosystem II (PSII). A well defined mechanism that protects the photosynthetic apparatus from photoinhibition has been described in the model green alga Chlamydomonas reinhardtii and plants. Chlorella ohadii is a green microalga, isolated from biological desert soil crusts, that thrives under extreme high light (HL) in which other organisms do not survive. Here, we show that this alga evolved unique protection mechanisms distinct from those of C. reinhardtii and plants. When grown under extreme HL, significant structural changes were noted in the C. ohadii thylakoids, including a drastic reduction in the antennae and the formation of stripped core PSII, lacking its outer and inner antennae. This is accompanied by a massive accumulation of protective carotenoids and proteins that scavenge harmful radicals. At the same time, several elements central to photoinhibition protection in C. reinhardtii, such as psbS, the stress related light harvesting complex (LHCSR), PSII protein phosphorylation and state transitions are entirely absent or were barely detected in C. ohadii.

Gill Transcriptomic Responses to Toxin-producing Alga Prymnesium parvum in Rainbow Trout

Project description:Prymnesium parvum is regarded as one of the most notorious harmful algal bloom (HAB) species worldwide. In recent years, it has frequently formed toxic blooms in coastal and brackish waters of America, Europe, Australia, Africa and Asia, causing large-scale mortalities of wild and cultured fish and other gill-breathing animals. In the last decade, blooms of P. parvum have expanded to inland fresh waters in the USA, presumably due to changes in environmental conditions. The aim of the experiment was to establish the gill transcriptomic responses to P. parvum in rainbow trout. We used 2 different concentrations of P. parvum and identified fish with low and moderate responses to the algae. Based on the dose of and the fish response, fish were classified into 4 groups with high exposure/moderate response (HM), high exposure/low response (HL), low exposure/low response (LL) and control group (C) with no exposure/no response. Gene expression profiling of the gill tissue was performed using a microarray platform developed and validated for rainbow trout.

A unique photoprotection mechanism in Chlorella species

A carotenoid biosynthesis related protein (CBR) is largely accumulated in the LHCII remains of HL cells and in the absence of psbS and LHCSR can function in sensing the HL and protecting from PI. Taken together, a unique photoinhibition protection mechanism evolved in C. ohadii, enabling the species to thrive under extremelight intensities where other photosynthetic organisms fail to survive.

Effect of long-term vitamin D supplementation on colonic gene expression in IL-10 Knockout mice at young adulthood

Project description:Low vitamin D status has been implicated in the progression of inflammatory bowel disease (IBD). This study used interleukin (IL)-10 knockout (KO) mice, that develop an intestinal inflammation when housed in a non-sterile environment, to determine if supplementation with vitamin D throughout life impacts colonic gene expression. Results provide important information on the intestinal response to vitamin D in inflamed mice. Female IL-10 knock out mice were randomized to 25 (Low, L) or 5000 (High, H) IU vitamin D/kg of diet throughout pregnancy and lactation. At weaning, offspring received the same or opposite diet as their mother until age 3 months. This resulted in four vitamin D interventions: HH, HL, LH, or LL where the first letter represents the diet consumed by dams during pregnancy and lactation and the second letter represents the diet consumed by offspring from weaning through to 3 months of age. Global gene expression was analyzed in the proximal colon of 3 months old mice (n=6 per group, for a total of 24 samples; samples came from different litters and moms IDs are given in the samples table below). Samples were stored at -80C.

Proteomic comparison of Chlamydomonas wildtype and calredoxin knock-down mutants via 14N/15N metabolic labeling

Project description:Calcium (Ca2+) and redox signaling play important roles in acclimation processes from archaea to eukaryotic organisms. Herein we characterized a unique protein from Chlamydomonas reinhardtii that has the competence to integrate Ca2+- and redox-related signaling. This protein, designated as calredoxin (CRX), combines four Ca2+-binding EF-hands and a thioredoxin (TRX) domain. A crystal structure of CRX, at 1.6 Å resolution, revealed an unusual calmodulin-fold of the Ca2+-binding EF-hands, which is functionally linked via an inter-domain communication path with the enzymatically active TRX domain. CRX is chloroplast-localized and interacted with a chloroplast 2-Cys-peroxiredoxin (PRX1). Ca2+-binding to CRX is critical for its TRX activity and for efficient binding and reduction of PRX1. Thereby, CRX represents a new class of Ca2+-dependent "sensor-responder" proteins. Genetically engineered Chlamydomonas strains with strongly diminished amounts of CRX revealed altered photosynthetic electron transfer and were affected in oxidative stress response underpinning a function of CRX in stress acclimation.

STN7 kinase-dependent Light-harvesting complex (LHC) protein phosphorylations in the moss Physcomitrium (Physcomitrella) patens

Project description:Photosystem (PS) I and PSII enclose the reaction center subunits and cofactors responsible for the conversion of sunlight into chemical energy. In the thylakoid membrane of oxygenic photosynthetic organisms, PSII splits the water molecules and donates electrons to the electron transfer chain, and further via PSI to form NADPH. Proteins of the light-harvesting complexes (LHC) I and II are mainly associated with PSI and PSII, respectively, but also provide dynamics for the adjustments of the absorption cross-section of PSII and PSI upon changing light conditions. LHCII proteins N-terminal phosphorylation affects their interaction either with PSI or with PSII, and is a molecular mechanism present from green algae and early land plants to higher plants. The kinase STN7 is responsible for N-terminal phosphorylation of the LHCII proteins in algae and flowering plants model species, but the specific targets and role of STN7-dependent reversible phosphorylation in formation of various PS-LHC complexes in evolutionarily early land plants like mosses is poorly studied. The aim of this project was to identify the phosphorylated residues of the LHCII subunits of the moss Physcomitrium (Physcomitrella) patens (hereafter: P. patens), i.e. the LHCBM proteins, and to determine which of the phosphosites are phosphorylated by the STN7 kinase. Subsequently, the goal has been to identify which of the LHCBM subunits that are part of PSI-LHCI-LHCII complex (state complex), and of the moss-specific PSI-Large complex, are N-terminally phosphorylated in the STN7-dependent fashion.

Probing the biogenesis pathway and dynamics of thylakoid membranes_C4PR_LIV

Project description:Thylakoid membranes are the specialized internal membrane system produced in plants, algae, and cyanobacteria to convert sunlight to chemical energy via oxygenic photosynthesis. Cyanobacterial thylakoid membranes harbor the protein complexes and electron transport molecules that are necessary for photosynthetic light reactions and respiratory electron flow. The thylakoid membranes sit between the plasma membrane and the central cytoplasm, leading to intricate cellular compartmentalization. How thylakoid membranes are generated to form the functional network and how protein complexes are recruited into thylakoids remain elusive. Here, we developed a method to modulate thylakoid biogenesis in the model cyanobacterium Synechococcus elongatus PCC7942 and probed the spatial-temporal stepwise biogenesis process of cyanobacterial thylakoid membranes, using electron microscopy, in situ cryo-electron tomography, confocal microscopy, mass spectroscopy, and biochemical approaches. Our results revealed that the plasma membrane and regularly-arranged concentric thylakoid layers have no physical connections. The newly synthesized thylakoid membrane fragments commerce between the plasma membrane and pre-existing thylakoids, where the initial biogenesis of Photosystem II occurs. Photosystem I monomers appear in thylakoid membranes earlier than other photosystem assemblies. Redistribution of photosynthetic protein complexes during thylakoid biogenesis ensures establishment of the spatial organization of the functional thylakoid membrane network. This study provides insights into the molecular processes of the photosynthetic machinery biosynthesis and organization.
