Physiological acclimation of plants to an everchanging environment is governed by complex combinatorial signaling networks that perceive and transduce various abiotic biotic stimuli. Reactive oxygen species (ROS) serve as one the second messengers in plant responses hyperosmotic stress. The molecular bases ROS production primary cellular processes they target were investigated Arabidopsis (Arabidopsis thaliana) root. Combined pharmacological genetic approaches showed RESPIRATORY BURST...
Cells maintain a constant dialog between the extracellular matrix and their plasma membrane to fine tune signal transduction processes. We found that receptor kinase FERONIA (FER), which is proposed cell wall sensor, modulates phosphatidylserine accumulation nano-organization, key regulator of Rho GTPase signaling in Arabidopsis. demonstrate FER required for both Rho-of-Plant 6 (ROP6) nano-partitioning at downstream production reactive oxygen species upon hyperosmotic stimulus. Genetic...
Diverging from conventional cell division models, plant cells undergo incomplete to generate plasmodesmata communication bridges between daughter cells. Although fundamental for multicellularity, the molecular events leading bridge stabilization, as opposed severing, remain unknown. Using electron tomography, we mapped transition plate fenestrae plasmodesmata. We show that endoplasmic reticulum (ER) connects across fenestrae, and matures, contract, causing plasma membrane (PM) mold around...
Membrane contact sites (MCSs) are fundamental actors of intracellular communication, but their role in intercellular communication remains unexplored. Here we show that plants, plasmodesmata cytoplasmic bridges function as atypical endoplasmic reticulum (ER)-plasma membrane (PM) tubular MCSs, operating at cell-cell interfaces. Similar to other ER-PM apposition within is controlled by a protein-lipid tethering complex. Unlike MCS however, regulation contacts primarily serves communication....
Abstract During their growth, plants encounter and respond to a variety of environmental signals. However, the mechanisms underlying integration specificity signals remain poorly understood. Rho Plant (ROP) signaling plays central role in various processes, including polar cell growth responses different stimuli, relies on stimuli-dependent membrane nanodomains. The effector composition ROP6 nanodomains varies depending signal may be involved downstream specificity. In this study, we explore...
Diverging from conventional cell division models, plant cells undergo incomplete to generate plasmodesmata communication bridges between daughter cells. While fundamental for multicellularity, the molecular events leading bridge stabilization, as opposed severing, remain unknown. Using electron tomography, we mapped transition plate fenestrae plasmodesmata. We show that ER connects across fenestrae, and matures, contract, causing PM mold around constricted tubes. The ER's presence prevents...
Abstract Iron (Fe) is an essential metal ion that plays a major role as cofactor in many biological processes. The balance between the Fe 2+ and 3+ forms central for cellular homeostasis because it regulates its transport, utilization, storage. Contrary to reduction crucial uptake by roots deficiency conditions, ferroxidation has been much less studied. In this work, we have focused on molecular characterization of two members MultiCopper Oxidase family (MCO1 MCO3) share high identity with...
Membrane contact sites (MCS) are fundamental for intracellular communication, but their role in intercellular communication remains unexplored. We show that plants, plasmodesmata bridges function as atypical endoplasmic reticulum (ER)-plasma membrane (PM) tubular MCS, operating at cell-cell interfaces. Similar to other ER-PM apposition is controlled by a protein-lipid tethering complex, uniquely, this serves communication. Combining high-resolution microscopy, molecular dynamics,...
ABSTRACT In the course of their growth and development plants have to constantly perceive react environment. This is achieved in cells, by coordination complex combinatorial signaling networks. However, how signal integration specificity are this context unknown. With a focus on hyperosmotic stimulus, we use live super-resolution light imaging methods demonstrate that Rho GTPase, Rho-of-Plant 6 (ROP6), forms stimuli-dependant nanodomains within PM. These necessary sufficient transduce...
Compared to other types of infrastructure (road, rail infrastructure), the energy sector is quite favorable. However, analysis shows that there scope for improvement through increased investment in power generation renewable sources and improving efficiency. Electricity an important production input, whereby price electricity has significant impact on overall level prices economy. In this context, increasing efficiency productivity electricity, reducing consumption GDP increase transmission...
