“…An increasing list of signaling components has been shown to shift between adjacent cells through plasmodesmata, thereby inducing nonautonomous functions (Sevilem et al 2012). Growth coordination is also set by mechanical feedback loops imposed by differential growth rates among adjacent cells (Hamant et al 2008;Heisler et al 2010;Uyttewaal et al 2012).…”

Root growth is modulated by differential hormonal sensitivity in neighboring cells

Coherent plant growth requires spatial integration of hormonal pathways and cell wall remodeling activities. However, the mechanisms governing sensitivity to hormones and how cell wall structure integrates with hormonal effects are poorly understood. We found that coordination between two types of epidermal root cells, hair and nonhair cells, establishes root sensitivity to the plant hormones brassinosteroids (BRs). While expression of the BR receptor BRASSINOSTEROID-INSENSITIVE1 (BRI1) in hair cells promotes cell elongation in all tissues, its high relative expression in nonhair cells is inhibitory. Elevated ethylene and deposition of crystalline cellulose underlie the inhibitory effect of BRI1. We propose that the relative spatial distribution of BRI1, and not its absolute level, fine-tunes growth.

“…Plasmodesmata (PD) allow for direct cytoplasmic connections in the plant and facilitate local molecular exchange among neighboring cells (Robards and Lucas, 1990;Blackman and Overall, 2001;Oparka and Roberts, 2001;Cilia and Jackson, 2004;Maule, 2008;Lucas et al, 2009;Burch-Smith et al, 2011;Sevilem et al, 2013). As PDs are initially formed during cell division, virtually all cells are born with plasmodesmal connections with their sister cells by default.…”

“…Yet, our quantitative understanding of these crucial hydraulic properties is hindered 45 by the complex organization and regulation of sub-cellular elements such as aquaporins, 46 which control the cell membrane permeability ( p L ) [Maurel and Chrispeels, 2001; Chaumont 47 and Tyerman, 2014] and plasmodesmata, which connect adjacent cells protoplasts [Maule,48 2008; Sevilem et al, 2013;Brunkard and Zambryski, 2017]. 49…”

Summary: 18-MECHA is a novel mathematical model that computes the flow of water through the 19 walls, membranes and plasmodesmata of each individual cell throughout complete 20 root cross-sections, from a minimal set of cell level hydraulic properties and detailed 21 root anatomical descriptions. 22 -Using the hydraulic anatomical framework of the Zea mays root reveals that 23 hydraulic principles at the cell and root segment scales, derived independently by 24 Katchalsky and Curran [1967] and Fiscus and Kramer [1975]
