Summary: Most microalgae use a CO2-concentrating mechanism (CCM) to acquire inorganic carbon in aquatic environments. This study found that the localization of a specific protein LCIB in the green alga Chlamydomonas reinhardtii undergoes changes in response to different CO2 concentrations, and this process is regulated by LCIC.

Summary: The development of a recombineering pipeline allowed for successful parallel cloning of genes from a Chlamydomonas bacterial artificial chromosome collection, with an overall cloning success rate of 77%. The cloning success was independent of gene size and complexity, with cloned genes reaching sizes as large as 23 kb. This technology has the potential to open up new possibilities in algal and plant research.

Summary: Researchers have developed a proximity labeling technique using TurboID to identify the protein composition of a crucial organelle in Chlamydomonas reinhardtii called the pyrenoid. The resulting high-confidence proteome revealed new insights into the role of the pyrenoid in RNA-associated processes and redox-sensitive iron-sulfur cluster metabolism.

Summary: The calcareous skeletons of stony corals consist of low-crystalline core and fibrous crystals. The formation of fibrous aragonite around the core is primarily regulated by abiotic environmental parameters. The coral's total mineralization is controlled by biological activities.

Summary: Using a transcriptomic data compendium of Chlamydomonas reinhardtii, we reconstructed a gene regulatory network and identified transcriptional regulators of photoprotection. Our study showed that the CCM regulator LCR1 also controls photoprotection, and QER7, a Squamosa Binding Protein, suppresses photoprotection and CCM-gene expression under the control of Phototropin. This study provides insights into gene expression regulation in microalgae.

Summary: Giant clams harbor symbiotic dinoflagellates that possess their own carbon concentration mechanism and are influenced by light exposure. The study indicates that light enhances the gene and protein expression levels of the symbiotic dinoflagellates in the clam's outer mantle, and different species may vary in their ability to generate CO2.

Summary: Allometric relationships of cell sizes within and across tissues and their associations with leaf dimensions and light-saturated photosynthetic rate were tested in grasses. The results showed similarities and exceptions to eudicots, highlighting the generality of evolutionary allometries within the grass lineage and their coordination with development and function.

Summary: Photosynthetic algae have evolved mechanisms to cope with suboptimal light and CO2 conditions. Depletion of CO2 can drive photoprotection and carbon acquisition even in the absence of light, previously believed to be indispensable for these processes.

Summary: Recent studies have quantified eCA and its activity in oceans for the first time, suggesting its potential as a biochemical indicator in biomonitoring programs and future research studies. The influence of environmental stressors on phytoplankton eCA activity highlights the need for further research to better understand its role in the marine carbon cycle in changing oceans.

Summary: A study has found that taurine can significantly promote the growth and photosynthesis efficiency of Symbiodinium sp., as well as positively affect its biomass and major metabolites. Taurine may also influence the metabolic pathways and transcription processes of Symbiodinium sp. through various mechanisms, while controlling the population density and initiating a series of response mechanisms.

Summary: This study provides the first comprehensive characterization of H+ transporters that may contribute to the homeostatic acid-base balance in coral cells, including members of the Na+/H+ exchanger, vacuolar-type electrogenic H+-ATP hydrolase, and voltage-gated proton channel families, as well as a novel member of the HvCN gene family. Key residues contributing to substrate specificity, protein function and regulation were identified, along with tissue-specific expression patterns and minimal impact of seawater acidification on most of these proteins.

Summary: The study suggests that scleractinian corals likely acquired the ability to calcify between approximately 308 and 265 million years ago through lineage-specific gene duplications and the co-option of existing genes. The evolution of coral calcification did not require extensive changes, but rather a few coral-specific gene duplications and gradual optimizations of ancestral proteins.

Summary: Research indicates that ocean acidification has a positive impact on the gene expression of coral endosymbionts, but leads to significant impairment in photosynthetic performance. This suggests that the over-expression of photosynthesis-related genes is not a beneficial effect of OA, but rather an acclimation response to different water chemistries.

Summary: Ocean warming and acidification, direct consequences of climate change, affect coral reefs worldwide. This study found that ocean acidification has stronger effects on the active microbial community associated with corals, compared to the resident community. The results suggest that rDNA- and rRNA-based sequencing are complementary tools for investigating the effects of environmental change on microbial assemblage structure and activity.

Summary: Members of the ammonium transporter family are found in all domains of life, but their molecular characterization in animals is limited. Recent studies have shown that ammonium plays various physiological roles in marine invertebrates, including in calcification. A specific ammonium transporter in the scleractinian coral Stylophora pistillata has been identified with potential involvement in coral calcification.
