“…Together, these cellular architectural elements constitute the bulwark of cellular senomic awareness. In our Cellular Basis of Consciousness (CBC) theory (Reber, 2019;Reber et al 2023), we proposed that the plasma membrane not only protects cells from the challenging environment but also allows the generation of the senome-based charged molecules, including diverse ions, and reactive radical species including charged molecules such as lipids, sugars, peptides, proteins and cytoskeletal polyelectrolyte-like biopolymers which all contribute to individual cellular subjective experiences (Baluška & Miller, 2018;Baluška & Mancuso, 2019;Tuszynski, 2019;Cruz et al, 2021;Alva et al, 2022;Hunley & Marucho, 2022). Sensory events at the plasma membrane modify the architectures of diverse intracellular senomic fields via the ordered release and annihilation of charged biomolecules.…”

Cells evolved some 4 billion years ago, and since then the integrity of the structural and functional continuity of cellular life has been maintained via highly conserved and ancient processes of cell reproduction and division. The plasma membrane as well as all the cytoplasmic structures are reproduced and inherited uninterruptedly by each of the two daughter cells resulting from every cell division. Although our understanding of the evolutionary emergence of the very first cells is obscured by the extremely long timeline since that revolutionary event, the generally accepted position is that the de novo formation of cells is not possible; all present cells are products of other prior cells. This essential biological principle was first discovered by Robert Remak and then effectively coined as Omnis Cellula e Cellula (every cell of the cell) by Rudolf Virchow: all currently living cells have direct structural and functional connections to the very first cells. Based on our previous theoretical analysis, all cells are endowed with individual sentient cognition that guides their individual agency, behaviour and evolution. There is a vital consequence of this new sentient and cognitive view of cells: when cells assemble as functional tissue ecologies and organs within multicellular organisms, including plants, animals and humans, these cellular aggregates display derivative versions of aggregate tissue‐ and organ‐specific sentience and consciousness. This innovative view of the evolution and physiology of all currently living organisms supports a singular principle: all organismal physiology is based on cellular physiology that extends from unicellular roots.

“…Action potentials are fundamental for facilitating long-distance signaling in plants and animals, and their functional linkage with the actin cytoskeleton associated with membranes is of utmost importance [261]. The actin cytoskeleton functions downstream of action potentials, which are accomplished through excitable membranes.…”

“…The plant-specific actin-based endocytic motor is involved in the myosin-actin-based gating of plant plasmodesmata, which is important for the transmission of action potentials between cells [268][269][270]. Action potentials regulate various aspects of plant life [261]. Precise connections between the inherent bioelectricity of eukaryotic membranes and the actin cytoskeleton are still under-investigated, and studies in this field serve as a fundamental pillar in our pursuit to comprehend actin-related cellular life activities.…”

The plant actin cytoskeleton is characterized by the basic properties of dynamic array, which plays a central role in numerous conserved processes that are required for diverse cellular functions. Here, we focus on how actins and actin-related proteins (ARPs), which represent two classical branches of a greatly diverse superfamily of ATPases, are involved in fundamental functions underlying signal regulation of plant growth and development. Moreover, we review the structure, assembly dynamics, and biological functions of filamentous actin (F-actin) from a molecular perspective. The various accessory proteins known as actin-binding proteins (ABPs) partner with F-actin to finely tune actin dynamics, often in response to various cell signaling pathways. Our understanding of the significance of the actin cytoskeleton in vital cellular activities has been furthered by comparison of conserved functions of actin filaments across different species combined with advanced microscopic techniques and experimental methods. We discuss the current model of the plant actin cytoskeleton, followed by examples of the signaling mechanisms under the supervision of F-actin related to cell morphogenesis, polar growth, and cytoplasmic streaming. Determination of the theoretical basis of how the cytoskeleton works is important in itself and is beneficial to future applications aimed at improving crop biomass and production efficiency.

“…Notably, the anterior-like heterotrophic root part is specialized for active searching for water and mineral nutrients while the posterior-like shoot part accomplishes photosynthesis and sexual reproduction [9]. Despite their typical modular nature [10][11][12][13][14][15], vascular plants are unitary organisms integrated via their vascular systems which support the plantspecific but neural-like communication via chemical, electrical and hydraulic long-distance signalling [10,[16][17][18][19][20][21].…”

“…In vascular plants having roots underground and shoots aboveground, supracellular systems integrating the whole plant body into a coherent unit are represented by vascular systems composed of vascular elements of xylem and phloem that are embedded within the vascular parenchyma. Although these vascular systems are studied mostly with respect to transport of solutes, minerals, hormones and other signals, as well as photosynthates, it is well known that vascular systems also allow rapid long-distance signalling and communication via electric, hydraulic and ROS/calcium waves [18][19][20][21][35][36][37][38].…”

Vascular plants are integrated into coherent bodies via plant-specific synaptic adhesion domains, action potentials (APs) and other means of long-distance signalling running throughout the plant bodies. Plant-specific synapses and APs are proposed to allow plants to generate their self identities having unique ways of sensing and acting as agents with their own goals guiding their future activities. Plants move their organs with a purpose and with obvious awareness of their surroundings and require APs to perform and control these movements. Self-identities allow vascular plants to act as individuals enjoying sociality via their self/non-self-recognition and kin recognition. Flowering plants emerge as cognitive and intelligent organisms when the major strategy is to attract and control their animal pollinators as well as seed dispersers by providing them with food enriched with nutritive and manipulative/addictive compounds. Their goal in interactions with animals is manipulation for reproduction, dispersal and defence. This article is part of the theme issue ‘Basal cognition: multicellularity, neurons and the cognitive lens’.
