In Arabidopsis thaliana, local wounding and herbivore feeding provoke leaf-to-leaf propagating Ca2+ waves that are dependent on the activity of members glutamate receptor-like channels (GLRs). systemic tissues, GLRs needed to sustain synthesis jasmonic acid (JA) with subsequent activation JA-dependent signaling response required for plant acclimation perceived stress. Even though role is well established, mechanism through which they activated remains unclear. Here, we report in vivo,...
Ca2+ signaling is central to plant development and acclimation. While Ca2+-responsive proteins have been investigated intensely in plants, only a few Ca2+-permeable channels identified, our understanding of how intracellular fluxes facilitated remains limited. Arabidopsis thaliana homologs the mammalian channel-forming mitochondrial calcium uniporter (MCU) protein showed transport activity vitro. Yet, evolutionary complexity MCU proteins, as well reports about alternative systems unperturbed...
Plants evolved in the presence of Earth's magnetic field (or geomagnetic field, GMF). Variations MF intensity and inclination are perceived by plants as an abiotic stress condition with responses at genomic metabolic level, changes growth developmental processes. The reduction GMF to near null (NNMF) values use a triaxial Helmholtz coils system was used evaluate requirement for Lima bean (Phaseolus lunatus L.) photosynthesis reactive oxygen species (ROS) production. leaf area, stomatal...
The geomagnetic field (GMF) is a natural component of the biosphere, and, during evolution, all organisms experienced its presence while some evolved ability to perceive magnetic fields (MF). We studied response 14-3-3 proteins and plasma membrane (PM) proton pump H+-ATPase reduced GMF values by lowering intensity near-null (NNMF). Seedling morphology, activity content, protein binding PM phosphorylation, gene expression, ROS quantification were assessed in maize (Zea mays) dark-grown...
The geomagnetic field (GMF) is a natural component of Earth’s biosphere. GMF reduction to near-null values (NNMF) induces gene expression modulation that generates biomolecular, morphological, and developmental changes. Here, we evaluate the effect NNMF on reactive oxygen species (ROS) production in time-course experiments Arabidopsis thaliana. Plants exposed triaxial Helmholtz coils system were sampled from 10 min 96 h differentially expressed genes (DEGs) oxidative stress responses by...
Phytopathogens are well known for their devastating activity that causes worldwide significant crop losses. However, exploitation welfare is relatively unknown. Here, we show the microbial volatile organic compound (mVOC) profile of bacterial phytopathogen, Erwinia amylovora, enhances Arabidopsis thaliana shoot and root growth. GC-MS head-space analyses revealed presence typical volatiles, including 1-nonanol 1-dodecanol. E. amylovora mVOCs triggered early signaling events plasma...
Two-Spotted Spider Mites (TSSMs, Tetranychus urticae Koch 1836 (Acari: Tetranychidae)) is one of the most important pests in many crop plants, and their feeding activity based on sucking leaf cell contents. The purpose this study was to evaluate interaction between TSSMs host Lima bean (Phaseolus lunatus) by analyzing metabolomics pigments transcriptomics TSSM guanine production. We also used epifluorescence, confocal laser scanning, transmission electron microscopies morphology structure...
