Abstract
Cell plate formation during cytokinesis entails multiple stages occurring concurrently and requiring orchestrated vesicle delivery, membrane remodelling, and timely deposition of polysaccharides, such as callose. Understanding such a dynamic process requires dissection in time and space; this has been a major hurdle in studying cytokinesis. Using lattice light sheet microscopy (LLSM), we studied cell plate development in four dimensions, through the behavior of yellow fluorescent protein (YFP)-tagged cytokinesis-specific GTPase RABA2a vesicles. We monitored the entire duration of cell plate development, from its first emergence, with the aid of YFP-RABA2a, in both the presence and absence of cytokinetic callose. By developing a robust cytokinetic vesicle volume analysis pipeline, we identified distinct behavioral patterns, allowing the identification of three easily trackable cell plate developmental phases. Notably, the phase transition between phase I and phase II is striking, indicating a switch from membrane accumulation to the recycling of excess membrane material. We interrogated the role of callose using pharmacological inhibition with LLSM and electron microscopy. Loss of callose inhibited the phase transitions, establishing the critical role and timing of the polysaccharide deposition in cell plate expansion and maturation. This study exemplifies the power of combining LLSM with quantitative analysis to decode and untangle such a complex process.

Abstract
Division plane positioning is critical for proper growth and development in many organisms. In plants, the division plane is established before mitosis, by accumulation of a cytoskeletal structure called the preprophase band (PPB). The PPB is thought to be essential for recruitment of division site localized proteins, which remain at the division site after the PPB disassembles. Here, we show that a division site localized protein, TANGLED1 (TAN1), is recruited independently of the PPB to the cell cortex at sites, by the plant cytokinetic machinery, the phragmoplast. TAN1 recruitment to de novo sites on the cortex is partially dependent on intact actin filaments and the myosin XI motor protein OPAQUE1 (O1). These data imply a yet unknown role for TAN1 and possibly other division site localized proteins during the last stages of cell division when the phragmoplast touches the cell cortex to complete cytokinesis.

Abstract
Asymmetric cell division generates different cell types and is a feature of development in multicellular organisms. Prior to asymmetric cell division, cell polarity is established. Maize (Zea mays) stomatal development serves as an excellent plant model system for asymmetric cell division, especially the asymmetric division of the subsidiary mother cell (SMC). In SMCs, the nucleus migrates to a polar location after the accumulation of polarly localized proteins but before the appearance of the preprophase band. We examined a mutant of an outer nuclear membrane protein that is part of the LINC (linker of nucleoskeleton and cytoskeleton) complex that localizes to the nuclear envelope in interphase cells. Previously, maize linc kash sine-like2 (mlks2) was observed to have abnormal stomata. We confirmed and identified the precise defects that lead to abnormal asymmetric divisions. Proteins that are polarly localized in SMCs prior to division polarized normally in mlks2. However, polar localization of the nucleus was sometimes impaired, even in cells that have otherwise normal polarity. This led to a misplaced preprophase band and atypical division planes. MLKS2 localized to mitotic structures; however, the structure of the preprophase band, spindle, and phragmoplast appeared normal in mlks2. Time-lapse imaging revealed that mlks2 has defects in premitotic nuclear migration toward the polarized site and unstable position at the division site after formation of the preprophase band. Overall, our results show that nuclear envelope proteins promote premitotic nuclear migration and stable nuclear position and that the position of the nucleus influences division plane establishment in asymmetrically dividing cells.

Abstract
Land plants depend on oriented cell divisions that specify cell identities and tissue architecture. As such, the initiation and subsequent growth of plant organs require pathways that integrate diverse systemic signals to inform division orientation. Cell polarity is one solution to this challenge, allowing cells to generate internal asymmetry both spontaneously and in response to extrinsic cues. Here, we provide an update on our understanding of how plasma membrane-associated polarity domains control division orientation in plant cells. These cortical polar domains are flexible protein platforms whose positions, dynamics, and recruited effectors can be modulated by varied signals to control cellular behavior. Several recent reviews have explored the formation and maintenance of polar domains during plant development [1-4], so we focus here on substantial advances in our understanding of polarity-mediated division orientation from the last five years to provide a current snapshot of the field and highlight areas for future exploration.
