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.

The heavy metal cadmium (Cd) is a major threat to food safety and human health. Phytoremediation the most widely used remediation technology, how improve efficiency of phytoremediation has become key issue. In this study, we constructed an intensive technology for Cd-contaminated soil with biodegradable chelating agent plant growth regulator combined maize investigated mechanism technology. results showed that best effect was achieved in treatment 10 −6 mol l −1 gibberellic acid (GA 3 ) 6 mmol kg aspartate diethoxysuccinic (AES) maize. treatment, total biomass extraction were 3.6 8.67 times higher than those control, respectively, antioxidant enzyme activities also increased. enriched dominant bacterial genera promote metabolism tolerance stress, which turn promoted Cd accumulation. Structural equation modelling indicated large concentration activity on extraction. enhanced good potential safe use soil.

Abstract Copper (Cu) is an essential element for plant growth but toxic when present in excess. In this study we the functional characterization of a petunia (Petunia hybrid) P1B-type heavy-metal ATPases (HMAs), PhHMA5II1. Heterologous expression PhHMA5II1 yeast (Saccharomyces cerevisiae) showed Cu transport activity. The PhHMA5II1 roots and shoots was unaffected by excess Cu. CRISPR/Cas9-edited mutant lines overexpressing transgenic plants were generated to investigate functions petunia. knockout hypersensitive accumulated more compared wild-type Overexpression enhanced tolerance reduced accumulation roots. Furthermore, localized endoplasmic reticulum, localization Yeast two-hybrid experiments bimolecular fluorescence complementation assays demonstrate that interact with copper chaperons, PhATX1 PhCCH. Finally, RNA-sequencing revealed affected genes involved cell wall organization, ion homeostasis, response oxidative stress. Taken together, plays important role detoxification
