Differential Expression of Eight Chitinase Genes in Medicago truncatula Roots During Mycorrhiza Formation, Nodulation, and Pathogen Infection
Molecular Plant-Microbe Interactions - Tập 13 Số 7 - Trang 763-777 - 2000
Peter Salzer, Athos Bonanomi, Katinka Beyer, Regina Vögeli‐Lange, Roger A. Aeschbacher, J. Lange, Andres Wiemken, Dong-Jin Park, Albert Vandenberg, Thomas Boller
Expression of eight different chitinase genes, representing members of five chitinase classes, was studied in Medicago truncatula roots during formation of arbuscular mycorrhiza with Glomus intraradices, nodulation with Rhizobium meliloti, and pathogen attack by Phytophthora megasperma f. sp. medicaginis, Fusarium solani f. sp. phaseoli (compatible interactions with root rot symptoms), Ascochyta p... hiện toàn bộ
Production ofSinorhizobium meliloti nodGene Activator and Repressor Flavonoids fromMedicago sativaRoots
Molecular Plant-Microbe Interactions - Tập 11 Số 8 - Trang 784-794 - 1998
José Ângelo Silveira Zuanazzi, Pierre Henri Clergeot, Jean‐Charles Quirion, H.‐P. HUSSON, Ádám Kondorosi, Pascal Ratet
During symbiosis between leguminous plants and rhizobia, flavonoids exuded by the plants act as chemoattractants and nodulation (nod) gene regulators in the other partner. To better understand the role of these compounds during the early steps of the alfalfa-Sinorhizobium meliloti symbiosis and the regulation of their production we have isolated nod gene inducers from alfalfa roots. All the compou... hiện toàn bộ
Involvement of the Octadecanoid Pathway in Bluegreen Aphid Resistance in Medicago truncatula
Molecular Plant-Microbe Interactions - Tập 20 Số 1 - Trang 82-93 - 2007
Ling‐Ling Gao, Jonathan P. Anderson, J. Klingler, Ramakrishnan M. Nair, Owain Edwards, Karam B. Singh
Aphids are major insect pests of plants that feed directly from the phloem. We used the model legume Medicago truncatula Gaert. (barrel medic) to elucidate host resistance to aphids and identified a single dominant gene which confers resistance to Acyrthosiphon kondoi Shinji (bluegreen aphid). To understand how this gene conditions resistance to bluegreen aphid, transcription profiling of 23 defen... hiện toàn bộ
Ethylene Signaling Modulates Herbivore-Induced Defense Responses in the Model Legume Medicago truncatula
Molecular Plant-Microbe Interactions - Tập 28 Số 5 - Trang 569-579 - 2015
Jamuna Risal Paudel, Jacqueline C. Bede
One or more effectors in the labial saliva (LS) of generalist Noctuid caterpillars activate plant signaling pathways to modulate jasmonate (JA)-dependent defense responses; however, the exact mechanisms involved have yet to be elucidated. A potential candidate in this phytohormone interplay is the ethylene (ET) signaling pathway. We compared the biochemical and molecular responses of the model leg... hiện toàn bộ
Recognition of Avirulence Gene AvrLm1 from Hemibiotrophic Ascomycete Leptosphaeria maculans Triggers Salicylic Acid and Ethylene Signaling in Brassica napus
Molecular Plant-Microbe Interactions - Tập 25 Số 9 - Trang 1238-1250 - 2012
Vladimír Šašek, Miroslava Nováková, Barbora Jindřichová, Károly Bóka, Olga Valentová, Lenka Burketová
Interaction of a plant with a fungal pathogen is an encounter with hundreds of molecules. In contrast to this, a single molecule often decides between the disease and resistance. In the present article, we describe the defense responses triggered by AvrLm1, an avirulence gene from a hemibiotrophic ascomycete, Leptosphaeria maculans, responsible for an incompatible interaction with Brassica napus. ... hiện toàn bộ
Homologs of Caenorhabditis elegans Chemosensory Genes Have Roles in Behavior and Chemotaxis in the Root-Knot Nematode Meloidogyne incognita
Molecular Plant-Microbe Interactions - Tập 32 Số 7 - Trang 876-887 - 2019
Tagginahalli N. Shivakumara, Tushar K. Dutta, Sonam Chaudhary, Stephan H. von Reuß, Valerie M. Williamson
Nematode chemosensation is a vital component of their host-seeking behavior. The globally important phytonematode Meloidogyne incognita perceives and responds (via sensory organs such as amphids and phasmids) differentially to various chemical cues emanating from the rhizosphere during the course of host finding. However, compared with the free-living worm Caenorhabditis elegans, the molecular int... hiện toàn bộ
MicroRNA844-Guided Downregulation of Cytidinephosphate Diacylglycerol Synthase3 (CDS3) mRNA Affects the Response of Arabidopsis thaliana to Bacteria and Fungi
Molecular Plant-Microbe Interactions - Tập 28 Số 8 - Trang 892-900 - 2015
Hwa Jung Lee, Young Ju Park, Kyung Jin Kwak, Dong-Hyun Kim, June Hyun Park, Jae Yun Lim, Chanseok Shin, Kwang‐Yeol Yang, Hunseung Kang
Despite the fact that a large number of miRNA sequences have been determined in diverse plant species, reports demonstrating the functional roles of miRNAs in the plant response to pathogens are severely limited. Here, Arabidopsis thaliana miRNA844 (miR844) was investigated for its functional role in the defense response to diverse pathogens. Transgenic Arabidopsis plants overexpressing miR844 (35... hiện toàn bộ
Nod Factor Thin-Layer Chromatography Profiling as a Tool to Characterize Symbiotic Specificity of Rhizobial Strains: Application toSinorhizobium saheli,S.teranga,andRhizobiumsp. Strains Isolated fromAcaciaandSesbania

Multiresistance Genes of Rhizobium etli CFN42
Molecular Plant-Microbe Interactions - Tập 13 Số 5 - Trang 572-577 - 2000
Ramón González-Pasayo, Esperanza Martı́nez-Romero
Multidrug efflux pumps of bacteria are involved in the resistance to various antibiotics and toxic compounds. In Rhizobium etli, a mutualistic symbiont of Phaseolus vulgaris (bean), genes resembling multidrug efflux pump genes were identified and designated rmrA and rmrB. rmrA was obtained after the screening of transposon-generated fusions that are inducible by bean-root released flavonoids.

Phylogenetic Perspectives on the Origins of Nodulation
Molecular Plant-Microbe Interactions - Tập 24 Số 11 - Trang 1289-1295 - 2011
Jeff J. Doyle
Recent refinements to the phylogeny of rosid angiosperms support the conclusion that nodulation has evolved several times in the so-called N2-fixing clade (NFC), and provide dates for these origins. The hypothesized predisposition that enabled the evolution of nodulation occurred approximately 100 million years ago (MYA), was retained in the various lineages that radiated rapidly shortly thereafte... hiện toàn bộ
