“…The increased content of citrulline and ornithine is also in agreement with previous results, with the former being an indicator of tolerance to several abiotic stresses in Cucumis melo , while the latter has been shown to accumulate in Chlorella vulgaris during cadmium stress (Kusvuran et al 2013 ). Finally, putrescine is one of the polyamines found in microalgae and known to participate in several molecular mechanisms employed by the cell in order to mitigate the adverse impacts from the environment (Xu et al 2021 ).…”

Microalgae species encounter oxidative stress in their natural environments, prompting the development of species-specific adaptation mechanisms. Understanding these mechanisms can offer valuable insights for biotechnological applications in microalgal metabolic manipulation. In this study, we investigated the response of Tetraselmis chuii, an industrially important microalga, to H2O2-induced oxidative stress. Exposure to 0.5-mM H2O2 resulted in reduced cell viability, and higher concentrations led to a drastic decline. After 1 h of exposure to H2O2, photosynthetic capacity (Qy) was negatively impacted, and this reduction intensified after 6 h of continuous stress. Global multi-omics analysis revealed that T. chuii rapidly responded to H2O2-induced oxidative stress within the first hour, causing significant changes in both transcriptomic and metabolomic profiles. Among the cellular functions negatively affected were carbon and energy flow, with photosynthesis-related PSBQ having a 2.4-fold downregulation, pyruvate kinase decreased by 1.5-fold, and urea content reduced by threefold. Prolonged exposure to H2O2 incurred a high energy cost, leading to unsuccessful attempts to enhance carbon metabolism, as depicted, for example, by the upregulation of photosystems-related PETC and PETJ by more than twofold. These findings indicate that T. chuii quickly responds to oxidative stress, but extended exposure can have detrimental effects on its cellular functions. Key points • 0.5-mM H2O2–induced oxidative stress strongly affects T. chuii • Distinct short- and long-term adaptation mechanisms are induced • Major metabolic adaptations occur within the first hour of exposure

“…RMAR6-6 has the capability to produce bacterioferritin, enhancing iron availability, which could be a vital metabolic interaction for promoting the growth of marine red algae in the ocean. Additionally, polyamines, including putrescine, are known to positively impact photosynthesis, cell proliferation and growth while providing protection against abiotic stresses in marine algae (Lin and Lin 2018 ; Xu et al 2021 ). RMAR6-6, with its ability to produce putrescine, may contribute to the growth enhancement or stress alleviation in marine red algae.…”

Mutualistic interactions between marine phototrophs and associated bacteria are an important strategy for their successful survival in the ocean, but little is known about their metabolic relationships. Here, bacterial communities in the algal sphere (AS) and bulk solution (BS) of nine marine red algal cultures were analyzed, and Roseibium and Phycisphaera were identified significantly more abundantly in AS than in BS. The metabolic features of Roseibium RMAR6-6 (isolated and genome-sequenced), Phycisphaera MAG 12 (obtained by metagenomic sequencing), and a marine red alga, Porphyridium purpureum CCMP1328 (from GenBank), were analyzed bioinformatically. RMAR6-6 has the genetic capability to fix nitrogen and produce B vitamins (B1, B2, B5, B6, B9, and B12), bacterioferritin, dimethylsulfoniopropionate (DMSP), and phenylacetate that may enhance algal growth, whereas MAG 12 may have a limited metabolic capability, not producing vitamins B9 and B12, DMSP, phenylacetate, and siderophores, but with the ability to produce bacitracin, possibly modulating algal microbiome. P. purpureum CCMP1328 lacks the genetic capability to fix nitrogen and produce vitamin B12, DMSP, phenylacetate, and siderophore. It was shown that the nitrogen-fixing ability of RMAR6-6 promoted the growth of P. purpureum, and DMSP reduced the oxidative stress of P. purpureum. The metabolic interactions between strain RMAR6-6 and P. purpureum CCMP1328 were also investigated by the transcriptomic analyses of their monoculture and co-culture. Taken together, potential metabolic relationships between Roseibium and P. purpureum were proposed. This study provides a better understanding of the metabolic relationships between marine algae and algae-associated bacteria for successful growth.

“…The polyamine biosynthetic pathway is conserved in bacteria, animals, and higher angiospermic plants [136]. Polyamines play an important role in physiological metabolism, which eliminates the active oxygen-free radicals, giving the plant tolerance to oxidative stresses [137]. Consequently, polyamines like putrescine and spermidine can help in the acclimation due to the oxidative stress caused by hyposaline conditions in green macroalga Ulva fasciata [47].…”

Plant hormones and pheromones are natural compounds involved in the growth, development, and reproductive processes. There is a plethora of studies on hormones and pheromones in terrestrial plants, but such investigations are few in the phycological literature. There are striking similarities between the chemical diversity, biosynthetic processes, roles, and actions of hormones and pheromones in both higher angiospermic plants and algae. However, there are substantial knowledge gaps in understanding the genes responsible for hormone biosynthesis and regulation in algae. Efforts have focused on identifying the genes and proteins involved in these processes, shedding light on lateral gene transfer and evolutionary outcomes. This comprehensive review contributes to benchmarking data and essential biotechnological tools, particularly for the aquaculture industry where seaweed is economically crucial. Advanced techniques in plant hormones and pheromones can revolutionize commercial aquaculture by using synthetic analogs to enhance growth, yield, and reproductive control, thereby addressing seasonal limitations and enabling sustainable seedling production. To the best of our knowledge, this is the first comprehensive review that focuses on biosynthetic pathways and modes of action (of five plant hormones and five pheromones), roles (of 11 hormones and 29 pheromones), and extraction protocols (of four hormones and six pheromones) reported in the phycological domain.
