Rhizobacteria protective hydrogel to promote plant growth and adaption to acidic soil

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Feb. 16, 2025

Endophytic plant growth promoting rhizobacteria (PGPRs) could replace chemical fertilizers in sustainable agriculture. Unfortunately, they are susceptible to harsh environmental conditions. Here, we proposed a polymeric hydrogel (PMH) consisting of carboxymethyl chitosan, sodium alginate, and calcium chloride for loading protecting endophytic PGPR. This can load PGPRs not only boost its growth-promoting efficiency, but also help them adapt more effectively environments. Using PGPR Ensifer C5 as model bacteria Brasscia napus host, demonstrate that the PMH facilitate colonization apical lateral root primordia regions. Further analysis indicates modulate suberin deposition endodermal cell layers regulate accumulation auxin at tip. Meanwhile, enhances antioxidant capacity disease resistance properties plants by increasing content arachidonic acid metabolism intermediates plant. Importantly, combination increases yields B. approximately 30% field. Furthermore, attenuates loss activity acidic Overall, this microbial encapsulation strategy is promising way protect fragile microorganisms, providing attractive avenues Plant fertilizers, authors report on protective enhance improve adaptability soil.

Light-based improvement technology for postharvest fruits and vegetables flavor and regulation mechanism: a review

Critical Reviews in Food Science and Nutrition, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 23

Published: Jan. 30, 2025

Fruits and vegetables (FVs) are consumed by humans for the distinctive flavors. Postharvest flavor declines limit its edible commercial value. Light, as a novel non-thermal technology, is becoming key strategy enhancing FVs flavor. This review integrated light treatment processes, summarized effects, mechanisms factors of emitting diodes (LEDs), ultraviolet (UV), pulsed (PL) γ-irradiation on Based photosensitization, photothermal photochemical four treatments demonstrate positive impacts compounds. They enhance 9%-48% amino acid, 7%-41.5% organic acids 4%-800% soluble sugar content. LEDs effectively boost taste aroma, most widely researched technology. UV PL exhibit outstanding effects aroma release, sweetness enhancement astringency bitterness mitigation, with also alleviating sourness degradation. γ-Radiation has been less explored, promotion effect accumulation observed. Factors such quality dose not overlooked. reduction future research should focus elucidating role photoreceptors in transcription regulation precise energy metabolism or other pathways regulating responding to signals.
