The study of Comorian red alga Halymenia durvillei showed a significant biochemical composition with high ash and polysaccharide content the presence n-3 n-6 essential fatty acid molecules. Seasonal monitoring real change in depending on harvesting period. On an annual average basis, algae contained 35.59 ± 2.55% dw ashes, 0.7 0.19% soluble proteins, 0.27 0.02% total lipids, 35.09 6.14% polysaccharides. pigment was 130 µg/g R-phycoerythrin, 1.49 chlorophyll a, 0.09 carotenoids. most abundant identified palmitic (C16:0), which accounted for almost 43.33% acids. Oleic (C18:1n-9) unsaturated acid, at 11.58%. Linoleic (C18:2n-6) reported to be polyunsaturated durvillei. profile also characterized by arachidonic (C20:4n-6) eicosapentaenoic (C20:5n-3).

Combined Effects of Marine Heatwaves and Light Intensity on the Physiological, Transcriptomic, and Metabolomic Profiles of Undaria pinnatifida

Plants, Год журнала: 2025, Номер 14(10), С. 1419 - 1419

Marine heatwaves (MHWs) are spreading across global oceanic regions with unprecedented intensity, frequency, and duration, often accompanied by changes in underwater light, thereby imposing multiple stressors on coastal macroalgae. In this study, the effects of MHW intensities (moderate: +3 °C; severe: +6 °C) light (normal: 90 μmol photons m−2 s−1; high: 270 s−1) cultivated Undaria pinnatifida were investigated through an integrated analysis physiological, transcriptomic, metabolomic responses. Under moderate conditions, U. exhibited enhanced growth photosynthetic performance, increased pigment content, improved electron transport, early activation antioxidant defenses. Following severe exposure, partial recovery some physiological traits was observed, while capacity, membrane integrity, energy metabolism remained impaired, oxidative damage not fully resolved. High stress further aggravated responses under both disrupting photoprotection weakening defense systems. These results suggest that exhibits adaptive capacity MHWs delayed incomplete MHWs. exacerbates responses, ultimately affecting yield quality.
