Water deficit is the major stress factor magnified by climate change that causes most reductions in plant productivity. Knowledge of photosystem II (PSII) response mechanisms underlying crop vulnerability to drought critical better understanding consequences on plants. Salicylic acid (SA) application under may stimulate PSII function, although exact mechanism remains essentially unclear. To reveal celery plants sprayed with water (WA) or SA, we employed chlorophyll fluorescence imaging analysis at 48 h, 96 and 192 h after watering. The results showed up watering, stroma lamellae SA-sprayed leaves appeared dilated, efficiency declined, compared WA-sprayed plants, which displayed a function. However, was restored, while SA boosted synthesis, ameliorating osmotic potential it resulted higher relative leaf content acting as an antioxidant stress, suppressed phototoxicity, thereby offering photoprotection, together enhanced effective quantum yield photochemistry (ΦPSII) decreased quantity singlet oxygen (1O2) generation photoprotection induced triggered non-photochemical quenching (NPQ), strategy protect chloroplast from photo-oxidative damage dissipating excess light energy heat. This photoprotective mechanism, NPQ adequate keeping, especially high-light conditions, equal fraction open reaction centers (qp) non-stress conditions. Thus, activates regulatory network partitioning signaling can mitigate, extent, functioning.

Summary Abiotic stress severely hinders plant growth and development, resulting in a considerable reduction crop yields. Salicylic acid (SA) serves as central signal mediating abiotic responses plants. Real‐time fluorescence tracking using specific probes can enhance our understanding of the SA‐triggered modulation underlying these events. However, complicated living microenvironments, selective recognition bioimaging SA is great challenge for scientists due to severe background interference analogues. Herein, an efficient probing technology employing highly rhodamine probe—phoxrodam was developed, which realizes precise salt‐stressed seedlings. Experimental findings reveal that phoxrodam demonstrates exceptional selectivity (fluorescence intensity: I Phoxrodam+SA / analogues > 4.29‐fold), high sensitivity (limit detection = 6.42 nM, quantum yield: Φ 0.36) good anti‐interference properties. Furthermore, we confirmed accurately detects roots wheat seedlings, low‐temperature resistance Nicotiana benthamiana heavy metal pea seeds, vivo confocal imaging. This study provides feasible strategy efficiently signalling molecules promotes in‐depth research SA‐mediated physiological mechanisms, laying key foundation future development new immune activation inducers.

Abstract Green technology, encompassing sustainable practices in food production, extends to dietary fiber extraction. This study aimed enhance extraction from the selected barley varieties (Jou‐17, Sultan‐17, and Pearl‐21) using ultrasonic‐assisted (UAE) technique. process involved washing, drying, de‐fatting (using ethanol as green solvent), protein removal steps. The response surface methodology (RSM) technique was used optimize yield of soluble (SDF; β‐glucan) with time, temperature, power. Optimal conditions yielded highest SDF (5.21%) all after 17.5 min at 41.70°C 130.5 W. FTIR pattern confirmed functional group tested sample. TGA DSC spectra determined thermal (β‐glucan). Monosaccharide composition that (β‐glucan) is glucose nature. Proximate analysis indicated Jou‐17 had moisture (13.4%) crude (10.10%) content. on other hand, maximum levels ash (2.75%), fat (1.22%), (8.84%). NFE, water‐holding capacity, oil‐holding foaming capacity extracted “Pearl‐21” variety were be 78.37%, 14.07 g/g, 6.99 126.17%, whereas foaming‐stability (96.26%) observed variety. PCA also association studied variables. In a nutshell, optimizing technology its favorable properties opens up promising paths for future endeavors contributes advancement health‐conscious industry.
