Summary: Harmful algal blooms are a global threat to marine ecosystems and human health. This study used translatome sequencing to investigate the molecular mechanisms of the Prorocentrum donghaiense algae. Through analyzing the translatome and proteome, the study found that up-regulation of energy and material production pathways in phosphor-rich conditions led to exponential growth of the algae in HABs. The researchers also demonstrated that mild translation delay using low concentrations of cycloheximide can control algal blooms without harming other aquatic organisms or humans.

Summary: A polymerase chain reaction-nucleic acid chromatography strip (PCR-NACS) method was established for the detection of Prorocentrum donghaiense. The PCR-NACS method is easy, sensitive, and visual, providing a potential new approach for the identification of P. donghaiense in natural water samples.

Summary: Prodigiosin can effectively control Prorocentrum donghaiense blooms by impacting chloroplasts and mitochondria, leading to lipid peroxidation and membrane damage. While it can arrest the cell cycle of P. donghaiense, surviving cells are able to repair and continue cycling after prodigiosin is removed by photodegradation. Prodigiosin shows potential for bloom control, but should be applied at night in small doses to minimize environmental impact.

Summary: Prorocentrum donghaiense is a bloom-forming dinoflagellate species that occurs annually in the East China Sea, with distinct succession patterns correlated with environmental factors. The blooms have impacts on marine ecosystems and further research is needed on nutrient budgets and socio-economic impacts.

Summary: This study provides a more feasible and universal seeding mechanism, the formation of resting cysts of the armored dinoflagellate Prorocentrum donghaiense. Through morpho-molecular methods, the research confirmed the distribution of P. donghaiense resting cysts in Chinese seas, filling a knowledge gap about the species' life history.

Summary: The research shows that modified clay can effectively reduce the biomass of harmful algal blooms through various mechanisms, including inducing programmed cell death. After application in residual blooms, modified clay alters the physiological state of the cells, leading to growth inhibition and increased reactive oxygen species production.

Summary: The study quantitatively compared the protein expression profiles of the dinoflagellate under different phosphorus conditions and found differential response mechanisms to DIP or DOP resupplementation. The results suggest that efficient DOP assimilation may be a key factor driving bloom formations of the dinoflagellate in a low DIP environment.

Summary: Blooms of the non-toxic dinoflagellate Prorocentrum donghaiense in the East China Sea significantly changed the structure and functions of the zooplankton community, leading to an increase in species richness and biodiversity after the bloom. During the bloom, the zooplankton community was dominated by carnivorousand egg-brooding- lineages represented by small jellyfish, chaetognaths, and copepods.

Summary: Bibliometric network analysis reveals that microplastics have detrimental effects on marine organisms. However, the combined effects of microplastics and climate change are not well understood. This study investigates the combined effects of microplastics and simulated ocean warming on a red tide species, Prorocentrum donghaiense. The results show that microplastics decrease cell growth, pigment contents, and electron transfer rate, but increase reactive oxygen species and antioxidant enzyme levels at low temperature. High temperatures have positive and negative effects depending on microplastic concentrations. These findings expand our knowledge on microalgae responses to increasing microplastic pollution in future warming scenarios.

Summary: The proliferation of toxin-producing microorganisms in marine and freshwater environments leads to water and seafood contamination, with harmful algal blooms increasing in frequency and intensity due to global climate change. Specifically, okadaic acid and dinophysistoxins are commonly found in EU waters, causing diarrhetic shellfish poisoning. Fish are also exposed to these toxins, but further research is needed to understand the ecological and food safety risks related to contamination with DSP toxins.

Summary: This study investigated the changes of zooplankton communities during a bloom of P. donghaiense in the coastal waters of southern Zhejiang Province, China. The results showed that the bloom could be divided into three major phases: growth, maintenance, and dissipation. The bloom had significant impacts on the abundance and species composition of zooplankton, particularly copepods.

Summary: This study highlights the high potential of Prorocentrum donghaiense, a dominant bloom-causing dinoflagellate, for lipid production. Compared to other oleaginous microalgae, P. donghaiense shows greater practical application potential due to its higher biomass and lipid contents. Nutrient deficiency and the algicidal bacterium Paracoccus sp. strain Y42 enhance the suitability of P. donghaiense lipid profile for biodiesel production, contributing to reductions in production costs.

Summary: Oyster production in Brazil is directly impacted by the quality of the environment, with harmful algal blooms, particularly O. cf. ovata, affecting oyster physiology and defense mechanisms. The study shows that C. gasar oysters are resilient to P. lima exposure but more susceptible to O. cf. ovata, which impairs oyster physiology and defense mechanisms, potentially leading to increased susceptibility to parasite infections.
