“…However, the molecular mechanism of heat-tolerance in N. yezoensis is still largely unknown. Our previous study reported that pre-treatment with SHE, a biostimulant extracted from Sargassum horneri, enhanced the heat-tolerance of N. yezoensis (Han et al, 2022). In the present study, we analyzed the transcriptomic regulation of heat-tolerance in N. yezoensis induced by SHE, which provided more information about heattolerance in N. yezoensis and the function of seaweed based biostimulants.…”

“…The clean thalli were then dried under 60°C and ground finely into powder using MM400 ball mill (Retsch, Germany). The biostimulant was prepared using the autoclaving method described in our previous study (Han et al, 2022). In brief, 8 g seaweed powder was added into 800 mL distilled water and stirred.…”

“…In addition to commercial biostimulants, some new biostimulants have been developed and tested in seaweed cultivation. Our previous study tested the effects of extraction methods on the activity of biostimulants from the bloom-forming brown alga, Sargassum horneri, and found the biostimulant extracted using boiling and autoclaving methods significantly enhanced the heat-tolerance of N. yezoensis gametophyte at 20°C (Han et al, 2022). The results suggest S. horneri extract has potential application in seaweed aquaculture.…”

IntroductionHeat stress is one of the main threats for the seaweed aquaculture, leading to the decay of the blades and causing serious economic losses. A newly developed biostimulant, Sargassum horneri extract (SHE), can enhance the heat-tolerance in Neopyropia yezoensis, which can be applied in the seaweed aquaculture. However, the molecular mechanism underlying this acquired heat-tolerance is still unclear.MethodIn this study, we examined the transcriptional regulation of N. yezoensis under heat stress after the SHE pre-treatment by performing the RNA-Seq on illumina Novaseq platform and differentially expressed gene analysis.Result and discussionOur results show that, under heat stress, the SHE pre-treatment can alleviate the suppression of genes involved in normal cell activities, such as ribosome biogenesis, photosynthesis, respiration and cell cycle. On the other hand, SHE pre-treatment can also induce some key genes involved in the heat-tolerance. We also found that the combination of SHE pre-treatment and heat stress can induce some genes related to epigenetic modification, suggesting that SHE may facilitate the formation of heat stress memory in N. yezoensis. Our study provides information for understanding the molecular mechanism of heat-tolerance in N. yezoensis and for promoting the application of seaweed-derived biostimulants in the seaweed aquaculture.

“…In turn, an acetone:ethanol extract of S. glaucescens rich in fucoxanthin caused a decrease in LPS-induced ROS and O 2 •− production in the same cell line at concentrations ranging from 25 µg/mL to 100 µg/mL [ 122 ]. The anti-inflammatory properties of fucoxanthin are further evidenced by in vivo studies in rodents [ 129 , 130 ], including scenarios of induced asthma [ 131 ] and induced colon inflammation [ 132 ].…”

“…S. vulgare extracts were also reported to increase the germination of Triticum durum [ 181 ] and Phaseolus vulgaris [ 130 ] under salt stress. Regarding crop protection, Shahriari and coworkers [ 129 ] recently highlighted the potential of S. angustifolium extracts to the improvement of drought tolerance in Brassica napus L., while Han et al [ 131 ] remarked the positive effect of S. horneri extracts on the thermal tolerance of Neopyropia yezoensis algae. In a different approach, the treatment of Solanum lycopersicum with S. tenerrimum and S. fusiforme extracts was found to enhance its resistance to the fungi Macrophomina phaseolina, [ 132 ] and to reduce the late blight and gray mold diseases [ 182 ], respectively.…”

Sargassum is one of the largest and most diverse genus of brown seaweeds, comprising of around 400 taxonomically accepted species. Many species of this genus have long been a part of human culture with applications as food, feed, and remedies in folk medicine. Apart from their high nutritional value, these seaweeds are also a well-known reservoir of natural antioxidant compounds of great interest, including polyphenols, carotenoids, meroterpenoids, phytosterols, and several others. Such compounds provide a valuable contribution to innovation that can translate, for instance, into the development of new ingredients for preventing product deterioration, particularly in food products, cosmetics or biostimulants to boost crops production and tolerance to abiotic stress. This manuscript revises the chemical composition of Sargassum seaweeds, highlighting their antioxidant secondary metabolites, their mechanism of action, and multiple applications in fields, including agriculture, food, and health.

metals are frequently found in the wastewater of many industries such as mining, foundry, electroplating (coating and protective treatments), surface finishing, battery manufacturing. Other strategic elements, such as rare earth elements (REEs) [3] (or noble metals [4] ) are also discharged into the environment through industrial wastewater, also joining the food chain as they are not biodegradable. Increasingly strict legislation, together with the sustainability objectives proposed by the United Nations as well as proactive policies, make new waste recycling processes necessary to save resources and achieve sustainable development. Cadmium is mainly used in batteries (about 80% of production); another common use of this metal protective compound concerns electroplate steel (especially for aircrafts and oil platforms). Less developed application concerns the control of atomic fission in nuclear reactors (for neutron absorption). [5] Therefore, removing this metal from wastewater is of crucial importance. Along with Cd, other heavy metals such as Ni, Hg, Zn, Cu, Pb, or Cr are often found in wastewater; [1a] therefore, nickel may be another interesting tracer of metal contamination for developing alternative sorption processes. On the other hand, rare earths are extracted from their ores (after leaching step) by ion exchange and solvent extraction, which generates waste streams that are harmful to the environment. [6] Rare earths have also become strategic metals in high-tech industry; 90% of the world's extraction and production is mainly controlled by China. [7] The REE supply recently became a geostrategic and political issue worldwide for industries based on energy storage, [8] and electronic devices. [9] Cadmium and nickel are frequently associated with industrial waste (such as in rechargeable Ni-Cd batteries). On the other hand, LaNi alloys are used for hydrogen storage, they are also associated in metal hybrid batteries for hybrid cars.There are many processes to recover or remove metals from wastewater streams, such as chemical precipitation, filtration membranes or ion exchange resins, among others. [1a,3a,10] However, most of these methods are generally expensive, they are not eco-friendly, they are inefficient especially at low metal concentrations, [11] and they can also generate new residues that, in turn, need to be treated. [12] Techniques such as bioremediation [13] or biosorption [14] can take advantage of the
