Hydrogen sulfide (H2S) is closely related to physiological diseases, environmental pollution, food safety, and plant growth. Herein, a new nopinone-based near-infrared fluorescent probe has been developed detect H2S with superior performance, including large Stokes shift, low detection limit, good selectivity, fast response time. NPD-H2S was used in water wine samples quantitatively. In addition, could be fabricate nanofiber membranes as portable tool for sensitively detecting vapor using smartphone. Moreover, effectively image HeLa cells, MCF-7 zebrafish. More importantly, the monitored presence of upregulation processes Arabidopsis thaliana under salt stress by bioimaging. This work provides concept intervention external stresses cultivation. Therefore, can monitor fluctuation environment living systems.

Hydrogen sulfide (H2S) plays a vital role in plant physiology and stress adaptation, but the detection of endogenous H2S remains challenge. In this work, near-infrared fluorescent probe (NIR-BOD-HS) was synthesized using boron-dipyrromethene (BODIPY) as raw material, which showed good linear relationship concentration range 0.1-70 μM limit 56 nM. The long-wavelength emission (712 nm) reduced interference autofluorescence improved imaging quality. combined with fluorescence technology nondestructively realized spatiotemporal distribution signal deep tissues plants. addition, dynamic changes content during seed germination seedling growth under abiotic were also demonstrated through signals. This study helps to understand physiological response mechanism plants provides scientific basis for further research on agricultural production.

Journal of Agricultural and Food Chemistry, Год журнала: 2025, Номер 73(18), С. 10701 - 10735

Опубликована: Апрель 28, 2025

Plants are constantly exposed to various stressors that can severely hinder their growth and threaten agricultural productivity. Recent advancements in plant imaging using fluorescent probes have opened new avenues for exploring the intricate processes involved stress perception signaling. This review represents comprehensive effort consolidate recent advances probe technologies, encompassing small-molecule probes, nanoprobes, genetically encoded indicators, as revolutionary tools deciphering stress-induced physiological dynamics. We present a classification of designed detecting key biomolecules responses, including reactive species, phytohormones, enzymes, other signaling molecules. By critically evaluating design principles, practical applications, distinct advantages over conventional analytical methods, we aim empower scientists unraveling spatiotemporal regulation networks. Finally, propose strategic directions overcome current technical bottlenecks maximize potential fluorescence-based sensing advancing sustainable agriculture.
