Genetic analysis of calcium spiking responses in nodulation mutants of Medicago truncatula
Wais, Rebecca J., Galera, Christine, Oldroyd, Giles, Catoira, Romy, Penmetsa, R. Varma, Cook, Douglas, ...
The symbiotic interaction between Medicago truncatula and Sinorhizobium meliloti results in the formation of nitrogen-fixing nodules on the roots of the host plant. The early stages of nodule...
Production and Characterization of Diverse Developmental Mutants of Medicago truncatula1
Penmetsa, R. Varma, Cook, Douglas R.
The diploid annual legume Medicago truncatula has been developed as a tractable genetic system for studying biological questions that are unique to, or well suited for study in legume species. An...
Differential Regulation of a Family of Apyrase Genes from Medicago truncatula1
Cohn, Jonathan R., Uhm, Taesik, Ramu, Senthil, Nam, Yong-Woo, Kim, Dong-Jin, Penmetsa, R. Varma, ...
Four putative apyrase genes were identified from the model legume Medicago truncatula. Two of the genes identified from M. truncatula (Mtapy1 and Mtapy4) are expressed in roots and are inducible...
Four Genes of Medicago truncatula Controlling Components of a Nod Factor Transduction Pathway
Catoira, Romy, Galera, Christine, De Billy, Francoise, Penmetsa, R. Varma, Journet, Etienne-Pascal, Maillet, Fabienne, ...
Rhizobium nodulation (Nod) factors are lipo-chitooligosaccharides that act as symbiotic signals, eliciting several key developmental responses in the roots of legume hosts. Using nodulation-defective...
Dual Genetic Pathways Controlling Nodule Number in Medicago truncatula1
Penmetsa, R. Varma, Frugoli, Julia A., Smith, Lucinda S., Long, Sharon R., Cook, Douglas R.
We report the isolation and characterization of a new Medicago truncatula hyper-nodulation mutant, designated sunn (super numeric nodules). Similar to the previously described ethylene-insensitive...
Kuppusamy, Kavitha T., Endre, Gabriella, Prabhu, Radhika, Penmetsa, R. Varma, Veereshlingam, Harita, Cook, Douglas R., ...
Ethyl methanesulfonate mutagenesis of the model legume Medicago truncatula has previously identified several genes required for early steps in nodulation. Here, we describe a new mutant that is...
Veereshlingam, Harita, Haynes, Janine G., Penmetsa, R. Varma, Cook, Douglas R., Sherrier, D. Janine, Dickstein, Rebecca
To investigate the legume-Rhizobium symbiosis, we isolated and studied a novel symbiotic mutant of the model legume Medicago truncatula, designated nip (numerous infections and polyphenolics). When...
Choi, Hong-Kyu, Kim, Dongjin, Uhm, Taesik, Limpens, Eric, Lim, Hyunju, Mun, Jeong-Hwan, ...
A core genetic map of the legume Medicago truncatula has been established by analyzing the segregation of 288 sequence-characterized genetic markers in an F(2) population composed of 93 individuals....

A Medicago truncatula phosphate transporter indispensable for the arbuscular mycorrhizal symbiosis
Javot, Hélène, Penmetsa, R. Varma, Terzaghi, Nadia, Cook, Douglas R., Harrison, Maria J.
The arbuscular mycorrhizal (AM) symbiosis is a mutualistic endosymbiosis formed by plant roots and AM fungi. Most vascular flowering plants have the ability to form these associations, which have a...
Middleton, Patrick H., Jakab, Júlia, Penmetsa, R. Varma, Starker, Colby G., Doll, Jake, Kaló, Péter, ...
Rhizobial bacteria activate the formation of nodules on the appropriate host legume plant, and this requires the bacterial signaling molecule Nod factor. Perception of Nod factor in the plant leads...
