[PMID: 38036295 DOI: 10.1093/plphys/kiad634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 10/18/2023] [Accepted: 11/07/2023] [Indexed: 12/02/2023]
Abstract
Root growth is sustained by cell division and differentiation of the root apical meristem (RAM), in which brassinosteroid (BR) signaling mediated via the dynamic targeting of BRASSINOSTEROID-INSENSITIVE1 (BRI1) plays complex roles. BRI1 is constitutively secreted to the plasma membrane (PM), internalized, and recycled or delivered into vacuoles, whose PM abundance is critical for BR signaling. Vesicle-target membrane fusion is regulated by heterotetrameric SNARE complexes. SNARE proteins have been implicated in BRI1 targeting, but how SNAREs affect RAM development is unclear. We report that Arabidopsis (Arabidopsis thaliana) YKT61, an atypical R-SNARE protein, is critical for BR-controlled RAM development through the dynamic targeting of BRI1. Functional loss of YKT61 is lethal for both male and female gametophytes. By using weak mutant alleles of YKT61, ykt61-partially complemented (ykt61-pc), we show that YKT61 knockdown results in a reduction of RAM length due to reduced cell division, similar to that in bri1-116. YKT61 physically interacts with BRI1 and is critical for the dynamic recycling of BRI1 to the PM. We further determine that YKT61 is critical for the dynamic biogenesis of vacuoles, for the maintenance of Golgi morphology, and for endocytosis, which may have a broad effect on development. Endomembrane compartments connected via vesicular machinery, such as SNAREs, influence nuclear-controlled cellular activities such as division and differentiation by affecting the dynamic targeting of membrane proteins, supporting a retro-signaling pathway from the endomembrane system to the nucleus.

TPLATE complex-dependent endocytosis attenuates CLAVATA1 signaling for shoot apical meristem maintenance. EMBO Rep 2023; 24:e54709.

Abstract
Endocytosis regulates the turnover of cell surface localized receptors, which are crucial for plants to rapidly respond to stimuli. The evolutionary ancient TPLATE complex (TPC) plays an essential role in endocytosis in Arabidopsis plants. Knockout or knockdown of single TPC subunits causes male sterility and seedling lethality phenotypes, complicating analysis of the roles of TPC during plant development. Partially functional alleles of TPC subunits however only cause mild developmental deviations. Here, we took advantage of the partially functional TPLATE allele, WDXM2, to investigate a role for TPC-dependent endocytosis in receptor-mediated signaling. We discovered that reduced TPC-dependent endocytosis confers a hypersensitivity to very low doses of CLAVATA3 peptide signaling. This hypersensitivity correlated with the abundance of the CLAVATA3 receptor protein kinase CLAVATA1 at the plasma membrane. Genetic and biochemical analysis as well as live-cell imaging revealed that TPC-dependent regulation of CLAVATA3-dependent internalization of CLAVATA1 from the plasma membrane is required for shoot stem cell homeostasis. Our findings provide evidence that TPC-mediated endocytosis and degradation of CLAVATA1 is a mechanism to dampen CLAVATA3-mediated signaling during plant development.

Abstract
The endomembrane system is critical for plant growth and development and understanding its function and regulation is of great interest for plant biology research. Small-molecule targeting distinctive endomembrane components have proven powerful tools to dissect membrane trafficking in plant cells. However, unambiguous elucidation of the complex and dynamic trafficking processes requires chemical probes with enhanced precision. Determination of the mechanism of action of a compound, which is facilitated by various chemoproteomic approaches, opens new avenues for the improvement of its specificity. Moreover, rational molecule design and reverse chemical genetics with the aid of virtual screening and artificial intelligence will enable us to discover highly precise chemical probes more efficiently. The next decade will witness the emergence of more such accurate tools, which together with advanced live quantitative imaging techniques of subcellular phenotypes, will deepen our insights into the plant endomembrane system.

Abstract
At the center of cell biology is our ability to image the cell and its various components, either in isolation or within an organism. Given its importance, biological imaging has emerged as a field of its own, which is inherently highly interdisciplinary. Indeed, biologists rely on physicists and engineers to build new microscopes and imaging techniques, chemists to develop better imaging probes, and mathematicians and computer scientists for image analysis and quantification. Live imaging collectively involves all the techniques aimed at imaging live samples. It is a rapidly evolving field, with countless new techniques, probes, and dyes being continuously developed. Some of these new methods or reagents are readily amenable to image plant samples, while others are not and require specific modifications for the plant field. Here, we review some recent advances in live imaging of plant cells. In particular, we discuss the solutions that plant biologists use to live image membrane-bound organelles, cytoskeleton components, hormones, and the mechanical properties of cells or tissues. We not only consider the imaging techniques per se, but also how the construction of new fluorescent probes and analysis pipelines are driving the field of plant cell biology.

Abstract
Several small-molecule perturbagens of the plant endomembrane system are known, but few selectively disrupt endoplasmic reticulum (ER) structure and function. We conducted a microscopy-based screen for small-molecule disruptors of ER structure and discovered eroonazole, a 1,2-4-triazole that induces extensive ER vesiculation in Arabidopsis seedlings. To identify eroonazole targets, we synthesized a clickable photoaffinity derivative and used it for whole-seedling labeling experiments. These reveal that the probe labels multiple oleosins, plant membrane proteins that stabilize ER-derived lipid droplets. Oleosin labeling is absent in an oleosin1234 quadruple mutant and reduced using an inactive analog. Cellular analyses of the ER in the quadruple mutant demonstrate that oleosins are required for normal ER structure during seed germination and suggest that perturbation of oleosin function by eroonazole underlies its effects on seedling ER structure.

Abstract
The widely used non-steroidal anti-inflammatory drugs (NSAIDs) are derivatives of the phytohormone salicylic acid (SA). SA is well known to regulate plant immunity and development, whereas there have been few reports focusing on the effects of NSAIDs in plants. Our studies here reveal that NSAIDs exhibit largely overlapping physiological activities to SA in the model plant Arabidopsis. NSAID treatments lead to shorter and agravitropic primary roots and inhibited lateral root organogenesis. Notably, in addition to the SA-like action, which in roots involves binding to the protein phosphatase 2A (PP2A), NSAIDs also exhibit PP2A-independent effects. Cell biological and biochemical analyses reveal that many NSAIDs bind directly to and inhibit the chaperone activity of TWISTED DWARF1, thereby regulating actin cytoskeleton dynamics and subsequent endosomal trafficking. Our findings uncover an unexpected bioactivity of human pharmaceuticals in plants and provide insights into the molecular mechanism underlying the cellular action of this class of anti-inflammatory compounds.

Abstract
The exocytosis process delivers proteins, lipids, and carbohydrates to the plasma membrane or the extracellular space to sustain plant cell growth, development, and response to environmental stimuli. Plant exocytosis is highly dynamic and requires the coordinated functions of multiple cellular components such as tethering complexes, GTPase signaling, and vesicle fusion machinery. Accurate spatio-temporal control of plant exocytosis is critical for the proper functions of plant cells. Live-cell imaging of fluorescence-tagged cargo proteins allows for quantitative analysis of exocytosis dynamics in plant cells. Small molecule inhibitors that target important components in the exocytosis machinery allow for transient manipulation of the exocytosis process. In this chapter, we describe procedures that use Endosidin2 (ES2) and Brefeldin A (BFA) as small molecule inhibitors to disrupt plant exocytic processes and use fluorescent protein-tagged PIN-formed 2 (PIN2) and Cellulose Synthase (CESA) as cargo proteins to quantify exocytosis dynamics in plant cells.

Abstract
Auxin is a key hormonal regulator, that governs plant growth and development in concert with other hormonal pathways. The unique feature of auxin is its polar, cell-to-cell transport that leads to the formation of local auxin maxima and gradients, which coordinate initiation and patterning of plant organs. The molecular machinery mediating polar auxin transport is one of the important points of interaction with other hormones. Multiple hormonal pathways converge at the regulation of auxin transport and form a regulatory network that integrates various developmental and environmental inputs to steer plant development. In this review, we discuss recent advances in understanding the mechanisms that underlie regulation of polar auxin transport by multiple hormonal pathways. Specifically, we focus on the post-translational mechanisms that contribute to fine-tuning of the abundance and polarity of auxin transporters at the plasma membrane and thereby enable rapid modification of the auxin flow to coordinate plant growth and development.

Abstract
Plants, like other multicellular organisms, survive through a delicate balance between growth and defense against pathogens. Salicylic acid (SA) is a major defense signal in plants, and the perception mechanism as well as downstream signaling activating the immune response are known. Here, we identify a parallel SA signaling that mediates growth attenuation. SA directly binds to A subunits of protein phosphatase 2A (PP2A), inhibiting activity of this complex. Among PP2A targets, the PIN2 auxin transporter is hyperphosphorylated in response to SA, leading to changed activity of this important growth regulator. Accordingly, auxin transport and auxin-mediated root development, including growth, gravitropic response, and lateral root organogenesis, are inhibited. This study reveals how SA, besides activating immunity, concomitantly attenuates growth through crosstalk with the auxin distribution network. Further analysis of this dual role of SA and characterization of additional SA-regulated PP2A targets will provide further insights into mechanisms maintaining a balance between growth and defense. SA modulates root development independently of NPR1-mediated canonical signaling SA attenuates growth through crosstalk with the auxin transport network SA upregulates the phosphorylation status of PIN auxin efflux carriers through PP2A SA directly targets A subunits of PP2A, inhibiting the activity of the complex

Abstract
Abiotic stresses, including drought, salinity, extreme temperature, and pollutants, are the main cause of crop losses worldwide. Novel climate-adapted crops and stress tolerance-enhancing compounds are increasingly needed to counteract the negative effects of unfavorable stressful environments. A number of natural products and synthetic chemicals can protect model and crop plants against abiotic stresses through induction of molecular and physiological defense mechanisms, a process known as molecular priming. In addition to their stress-protective effect, some of these compounds can also stimulate plant growth. Here, we provide an overview of the known physiological and molecular mechanisms that induce molecular priming, together with a survey of the approaches aimed to discover and functionally study new stress-alleviating chemicals.

Abstract
The regulated dynamic transport of materials among organelles through endomembrane trafficking pathways is essential for plant growth, development, and environmental adaptation, and thus is a major topic of plant biology research. Large-scale chemical library screens have identified small molecules that could potentially inhibit different plant endomembrane trafficking steps. Further characterization of these molecules has provided valuable tools for understanding plant endomembrane trafficking and uncovered novel regulators of trafficking processes.
