“…NO also plays an important role in the cell cycle ( Correa-Aragunde et al., 2006 ; Novikova et al., 2017 ) and auxin-mediated activation of cell division ( Ötvös et al., 2005 ). In the same way, Sánchez-Vicente et al. (2021) indicated that NO altered the pattern of auxin maxim and PIN-FORMED1 (regulates auxin basipetal transport) during shoot development.…”

Nitric oxide (NO), an ancient molecule with multiple roles in plants, has gained momentum and continues to govern plant biosciences-related research. NO, known to be involved in diverse physiological and biological processes, is a central molecule mediating cellular redox homeostasis under abiotic and biotic stresses. NO signaling interacts with various signaling networks to govern the adaptive response mechanism towards stress tolerance. Although diverging views question the role of plants in the current greenhouse gases (GHGs) budget, it is widely accepted that plants contribute, in one way or another, to the release of GHGs (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3)) to the atmosphere, with CH4 and N2O being the most abundant, and occur simultaneously. Studies support that elevated concentrations of GHGs trigger similar signaling pathways to that observed in commonly studied abiotic stresses. In the process, NO plays a forefront role, in which the nitrogen metabolism is tightly related. Regardless of their beneficial roles in plants at a certain level of accumulation, high concentrations of CO2, CH4, and N2O-mediating stress in plants exacerbate the production of reactive oxygen (ROS) and nitrogen (RNS) species. This review assesses and discusses the current knowledge of NO signaling and its interaction with other signaling pathways, here focusing on the reported calcium (Ca2+) and hormonal signaling, under elevated GHGs along with the associated mechanisms underlying GHGs-induced stress in plants.

“…Also, NO levels are regulated by the phytohormone ethylene. The accumulation of NO has been detected in meristematic zones and throughout the petioles of Arabidopsis seedlings (Sánchez‐Vicente, Lechón, Fernández‐Marcos, Sanz, & Lorenzo, 2021). Katano, Oi, and Suzuki (2020) detected NO during pollen‐stigma interaction in sunflower under heat stress using DAF‐2DA.…”

The free radical nitric oxide (NO) has emerged as an important signal molecule in plants, due to its involvement in various plant growth, development, and stress responses. For elucidating the role of NO, it is very important to precisely determine, localize, and quantify NO levels. Due to a relatively short half‐life and its rapid, complex reactivity with other radicals, together with its capacity to diffuse from the source of production, the quantification of NO in whole plants, tissues, organelles, and extracts is notoriously difficult. Hence, it is essential to employ sensitive procedures for precise detection of NO. Currently available methods can fulfill many requirements to precisely determine NO, but each method has several advantages and pitfalls. In this article, we describe a detailed procedure for the measurement of NO by diaminofluorescein (DAF) in cell‐permeable forms (DAF‐FM‐DA). In this method, the tissues are immersed in DAF‐FM DA, leading to their diffusion from the plasma membrane to the inside of the cell, where intracellular esterases cleave the ester bonds, leading to DAF‐FM release. The resulting DAF‐FM reacts with intracellularly generated NO and forms highly fluorescent triazolofluorescein (DAF‐FMT), which can be localized and monitored by fluorescence or confocal microscopy, and can also be detected via fluorimetry and flow cytometry. DAF dyes are very popular as they are non‐invasive, relatively easy to handle, and commercially available. Another precise and very sensitive method is chemiluminescence detection of NO, where NO reacts with ozone (O3), leading to emission of a quantum of light from which NO can be calculated. Using chickpea seedlings, we describe in detail the measurement of NO using DAF‐FM‐DA and chemiluminescence methods. © 2022 Wiley Periodicals LLC.

“…The lack of GSNOR1 inhibits the endocytosis of PINs by an uncertain mechanism. Both GNOM and PID have hypothetical SNO modifications ( Ni et al, 2017 ; Sanchez-Vicente et al, 2021 ). The influence of GSNOR also indicates that PIN polarity may be affected by NO.…”

Auxin regulates plant growth and tropism responses. As a phytohormone, auxin is transported between its synthesis sites and action sites. Most natural auxin moves between cells via a polar transport system that is mediated by PIN-FORMED (PIN) auxin exporters. The asymmetrically localized PINs usually determine the directionality of intercellular auxin flow. Different internal cues and external stimuli modulate PIN polar distribution and activity at multiple levels, including transcription, protein stability, subcellular trafficking, and post-translational modification, and thereby regulate auxin-distribution-dependent development. Thus, the different regulation levels of PIN polarity constitute a complex network. For example, the post-translational modification of PINs can affect the subcellular trafficking of PINs. In this review, we focus on subcellular trafficking and post-translational modification of PINs to summarize recent progress in understanding PIN polarity.
