The ability of plants to monitor their surroundings, for instance the perception bacteria, is crucial importance. microorganism-derived molecules and effector proteins best understood these monitoring processes. In addition, perceive bacterial quorum sensing (QS) used cell-to-cell communication between bacteria. Here, we propose a mechanism how N-acyl-homoserine lactones (AHLs), group QS molecules, influence host defense fortify resistance in Arabidopsis thaliana against pathogens....
In plants, the topological organization of membranes has mainly been attributed to cell wall and cytoskeleton. Additionally, few proteins, such as plant-specific remorins have shown function protein lipid organizers. Root nodule symbiosis requires continuous membrane re-arrangements, with bacteria being finally released from infection threads into membrane-confined symbiosomes. We found that mutations in symbiosis-specific SYMREM1 gene result highly disorganized perimicrobial membranes....
Summary The implementation of beneficial microorganisms for plant protection has a long history. Many rhizobia bacteria are able to influence the immune system host plants by inducing resistance towards pathogenic microorganisms. In this report, we present translational approach in which demonstrate resistance‐inducing effect E nsifer meliloti ( S inorhizobium ) on crop that have significant impact worldwide economy and human nutrition. is usually associated with root nodulation legumes...
The initiation of intracellular host cell colonization by symbiotic rhizobia in Medicago truncatula requires repolarization root hairs, including the rearrangement cytoskeletal filaments. molecular players governing microtubule (MT) reorganization during rhizobial infections remain to be discovered. Here, we identified M. DEVELOPMENTALLY REGULATED PLASMA MEMBRANE POLYPEPTIDE (DREPP), a member MT binding DREPP/PCaP protein family, and investigated its functions infections. We show that drepp...
Salmonella is one of the most prominent causes food poisoning and growing evidence indicates that contaminated fruits vegetables are an increasing concern for human health. Successful infection demands suppression host immune system, which often achieved via injection bacterial effector proteins into cells. In this report we present function protein in plant cell, supporting new concept trans-kingdom competence bacterium. We screened a range Typhimurium interference with immunity. Among...
Abstract Background N -3-oxo-tetradecanoyl- L -homoserine lactone (oxo-C14-HSL) is one of the -acyl homoserine lactones (AHL) that mediate quorum sensing in Gram-negative bacteria. In addition to bacterial communication, AHL are involved interactions with eukaryotes. Short-chain easily taken up by plants and transported over long distances. They promote root elongation growth. Plants typically do not uptake hydrophobic sidechain such as oxo-C14-HSL, although they prime for enhanced...
Nitrogen is an essential macronutrient and a key cellular messenger. Plants have evolved refined molecular systems to sense the nitrogen status. This exemplified by root nodule symbiosis between legumes symbiotic rhizobia, where nitrate availability inhibits this mutualistic interaction. Additionally, also functions as metabolic messenger, resulting in signaling cascades which intensively crosstalk with other physiological pathways. Nodule inception-like proteins (NLPs) are players regulate...
Abstract Organization of membrane topologies in plants has so far been mainly attributed to the cell wall and cytoskeleton. Taking rhizobial infections legume root cells, where plasma membranes undergo dynamic large-scale topology changes, as an initial model, we challenged this paradigm tested whether additional scaffolds such plant-specific remorins that accumulate on highly curved often wall-less domains, control local dynamics. Indeed, loss-of-function mutants remorin protein SYMREM1...
Abstract The initiation of intracellular host cell colonization by symbiotic rhizobia in Medicago truncatula requires repolarization root hairs, which includes the re-arrangement cytoskeletal filaments. molecular players governing microtubule (MT) re-organization during infection remain to be discovered. Here, we identified M. DREPP protein and investigated its functions rhizobial infections. We show that drepp mutant roots as well transgenic over-expressing is impaired. re-localizes into...
Abstract Quorum sensing (QS) molecules mediate communication between bacterial cells. N -acyl homoserine lactones (AHL) are one of the best-studied groups QS molecules. In addition to communication, AHL involved in interactions with eukaryotes. Short side-chain readily taken up by plants. They induce root elongation and growth promotion. Hydrophobic long usually not transported over distances although, they may prime plants for enhanced resistance. Unfortunately, studies elucidating plant...
