“…Importantly, such complex redox contexts are not unique. The plant’s microbiome (the narrow rhizosphere surrounding its roots) is similarly complex with the roots supplying a local source of oxygen, − both the root “host” and its microbiome providing diffusible redox-active metabolites, and the extracellular matrix rich in redox-active humic substances. − Both these examples illustrate that redox signaling occurs within a complex redox context and conveys information across biological kingdoms (the host and its microbiome).…”

Biology uses well-known redox mechanisms for energy harvesting (e.g., respiration), biosynthesis, and immune defense (e.g., oxidative burst), and now we know biology uses redox for systems-level communication. Currently, we have limited abilities to "eavesdrop" on this redox modality, which can be contrasted with our abilities to observe and actuate biology through its more familiar ionic electrical modality. In this Perspective, we argue that the coupling of electrochemistry with diffusible mediators (electron shuttles) provides a unique opportunity to access the redox communication modality through its electrical features. We highlight previous studies showing that mediated electrochemical probing (MEP) can "communicate" with biology to acquire information and even to actuate specific biological responses (i.e., targeted gene expression). We suggest that MEP may reveal an extent of redox-based communication that has remained underappreciated in nature and that MEP could provide new technological approaches for redox biology, bioelectronics, clinical care, and environmental sciences.

“…Variations in water depth greatly impact the growth and development of submerged macrophytes (Coops et al., 2003 ; Ersoy et al., 2020 ), due to changes in multiple environmental factors, especially the underwater light intensity (Wang, Wang, et al., 2021 ; Yuan et al., 2018 ). Behaving like shade‐adapted species, submerged macrophytes generally have a low tolerance of high light intensity in shallow‐water environments (Bowes & Salvucci, 1989 ; Hussner et al., 2010 ), whereas reduced light availability in deep waters can hamper their photosynthesis or root respiration (Han et al., 2019 ). The optimal water depth range has been identified for numerous species (Liu et al., 2016 ), outside of these ranges, macrophytes have to make adjustments.…”
