Plant cell separation and expansion require pectin degradation by endogenous pectinases such as polygalacturonases, few of which have been functionally characterized. Stomata are a unique system to study both processes because stomatal maturation involves limited between sister guard cells responses reversible elongation contraction. However, the molecular mechanisms for how pores form walls facilitate dynamic remain poorly understood. We characterized POLYGALACTURONASE INVOLVED IN...
Abstract Pectins are abundant in the cell walls of dicotyledonous plants, but how they interact with other wall polymers and influence integrity growth has remained mysterious. Here, we verified that QUASIMODO2 (QUA2) is a pectin methyltransferase determined QUA2 required for normal biosynthesis. To gain further insight into affects assembly maintenance, investigated cellulose biosynthesis, organization, cortical microtubules, signaling two mutant alleles Arabidopsis (Arabidopsis thaliana)...
Abstract For fertilization to occur in plants, the pollen tube must be guided enter ovule via micropyle. Previous reports have implicated actin filaments, binding proteins, and tip-focused calcium gradient as key contributors polar growth of tubes; however, regulation directional is largely unknown. We reported previously that Arabidopsis thaliana MICROTUBULE-ASSOCIATED PROTEIN18 (MAP18) contributes cell cortical microtubule organization. The preferential expression MAP18 tubes suggests also...
Abstract Stomatal guard cells are pairs of specialized epidermal that control water and CO2 exchange between the plant environment. To fulfill functions stomatal opening closure driven by changes in turgor pressure, cell walls must be both strong flexible, but how structure dynamics enable function remains poorly understood. address this question, we applied biological genetic analyses to investigate their relationship Arabidopsis (Arabidopsis thaliana). Using live-cell spinning disk...
One key aspect of cell division in multicellular organisms is the orientation plane. Proper plane establishment contributes to normal plant body organization. To determine importance geometry orientation, we designed a three-dimensional probabilistic mathematical model directly test century-old hypothesis that divisions mimic soap-film minima. According this hypothesis, daughter cells have equal volume and occurs where surface area at minimum. We compared predicted planes microtubule array...
Stomata function as osmotically tunable pores that facilitate gas exchange at the surface of plants. Stomatal opening and closure are regulated by turgor changes in guard cells result mechanically deformations cell walls. However, how molecular, architectural, mechanical heterogeneities exist walls affect stomatal dynamics is unclear. In this work, stomata wild type Arabidopsis thaliana plants or mutants lacking normal cellulose, hemicellulose, pectins were experimentally induced to close...
Stomatal pores are vital for the diffusion of gasses into and out land plants are, therefore, gatekeepers photosynthesis transpiration. Although much published literature has described intercellular signaling transcriptional regulators involved in early stomatal development, little is known about cellular details local separation between sister guard cells that give rise to pore or how formation this achieved. Using three-dimensional (3D) time-lapse imaging, we found Arabidopsis (Arabidopsis...
Cell walls are likely to be essential determinants of the amazing strength and flexibility guard cells that surround each stomatal pore in plants, but surprisingly little is known about cell wall composition, organization, dynamics cells. Recent analyses organization function Arabidopsis thaliana mutants with defects cellulose xyloglucan have allowed for development new hypotheses relative contributions these components function. Advanced image analysis methods can allow automated detection...

The seismic performance RC columns confined different NiTiNb SMA spacing and heights is compared through series quasi-static tests. are tested under compression loadings. that as-built column. test results demonstrate significantly improves ductility energy dissipation capacity, has slight effect peak strength piers. reduce crashing...
Abstract One key aspect of cell division in multicellular organisms is the orientation plane. Proper plane establishment contributes to normal organization plant body. To determine importance geometry orientation, we designed a threedimensional probabilistic mathematical modeling approach directly test century-old hypothesis that divisions mimic “soap-film minima” or daughter cells have equal volume and resulting local surface area minimum. Predicted planes were compared microtubule array...
