Rapid evolutionary change of common bean (Phaseolus vulgaris L) plastome, and the genomic diversification of legume chloroplastsXianwu Guo
Programa de Genómica Evolutiva, Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Apartado Postal 565 A, C P 62210, Cuernavaca, Morelos, Mexico
BMC Genomics 8:228. 2007..In contrast to what we know about their great diversity or economic importance, our knowledge at the genomic level of chloroplast genomes (cpDNAs or plastomes) for these crops is limited...
Horizontal gene transfer and diverse functional constrains within a common replication-partitioning system in Alphaproteobacteria: the repABC operonSantiago Castillo-Ramírez
Programa de Genómica Evolutiva, Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Cuernavaca, Morelos, Mexico
BMC Genomics 10:536. 2009..Here, we tested whether there is a common evolutionary history within the repABC operon. We further examined different incompatibility groups in terms of their differentiation and degree of adaptation to their host...
Genomic lineages of Rhizobium etli revealed by the extent of nucleotide polymorphisms and low recombinationJosé L Acosta
Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Av Universidad N C Col Chamilpa, Apdo Postal 565 A, Cuernavaca 62210, Mexico
BMC Evol Biol 11:305. 2011..Here, we compared draft genomic sequences versus complete genomic sequences to obtain reliable measures of genetic diversity and then estimated the role of recombination in the generation of genomic diversity among Rhizobium etli...
Factors affecting the concordance between orthologous gene trees and species tree in bacteriaSantiago Castillo-Ramírez
Programa de Genómica Evolutiva, Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Apartado Postal 565 A, CP 62210, Cuernavaca, Morelos, Mexico
BMC Evol Biol 8:300. 2008....
Conserved symbiotic plasmid DNA sequences in the multireplicon pangenomic structure of Rhizobium etliVictor Gonzalez
Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Av Universidad N C Col Chamilpa, Apdo Postal 565 A, Cuernavaca 62210, Mexico
Appl Environ Microbiol 76:1604-14. 2010..We concluded that R. etli has a pangenomic structure with a core genome composed of both chromosomal and plasmid sequences, including a highly conserved symbiotic plasmid, despite the overall genomic divergence...
The partitioned Rhizobium etli genome: genetic and metabolic redundancy in seven interacting repliconsVictor Gonzalez
Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, AP565 A Cuernavaca, Morelos, 62210, Mexico
Proc Natl Acad Sci U S A 103:3834-9. 2006..Twenty-three putative sigma factors, numerous isozymes, and paralogous families attest to the metabolic redundancy and the genomic plasticity necessary to sustain the lifestyle of R. etli in symbiosis and in the soil...
Evolutionary dynamics of insertion sequences in relation to the evolutionary histories of the chromosome and symbiotic plasmid genes of Rhizobium etli populationsLuis Lozano
Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Cuernavaca, Morelos, Mexico
Appl Environ Microbiol 76:6504-13. 2010..These results suggest that the R. etli populations diverged recently in Mexico, that the symbiotic plasmid also had a recent origin, and that the IS elements have undergone a process of cyclic infection and expansion...
Transfer of the symbiotic plasmid of Rhizobium etli CFN42 requires cointegration with p42a, which may be mediated by site-specific recombinationSusana Brom
Programa de Genetica Molecular de Plasmidos Bacterianos, Centro de Investigacion Sobre Fijacion de Nitrogeno, UNAM, Cuernavaca, Morelos, Mexico
J Bacteriol 186:7538-48. 2004....
DNA diversification in two Sinorhizobium speciesXianwu Guo
Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Ap Postal 565 A, Cuernavaca, Morelos, Mexico
J Bacteriol 189:6474-6. 2007..genomes clearly demonstrate that DNA recombination among closely related bacteria is a major event in the diversification of this genome, especially in pSymA, resulting in mosaic structure...
Diversification of DNA sequences in the symbiotic genome of Rhizobium etliMargarita Flores
, , Ap. Postal 565-A, Cuernavaca, Morelos,
J Bacteriol 187:7185-92. 2005..We propose that the horizontal transfer of homologous DNA segments among closely related organisms is a major source of genomic diversification...
The Rhizobium etli RpoH1 and RpoH2 sigma factors are involved in different stress responsesJaime M Martínez-Salazar
Programa de Ingeniería Genómica, Centro de Ciencias Genomicas, Departamento de Biologia Molecular de Plantas, Universidad Nacional Autonoma de Mexico, Apartado Postal 565 A, CP 62210 Cuernavaca, Morelos, Mexico
Microbiology 155:386-97. 2009..In conclusion, the two RpoH proteins operate under different stress conditions, RpoH1 in heat-shock and oxidative responses, and RpoH2 in osmotic tolerance...
The Rhizobium etli sigma70 (SigA) factor recognizes a lax consensus promoterMiguel A Ramírez-Romero
Programa de Genómica Evolutiva, Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Apartado Postal 565 A, C P 62210, Cuernavaca, Morelos, Mexico
Nucleic Acids Res 34:1470-80. 2006....
Conjugative transfer of p42a from rhizobium etli CFN42, which is required for mobilization of the symbiotic plasmid, is regulated by quorum sensingCristina Tun-Garrido
Programa de Genetica Molecular de Plasmidos Bacterianos, Centro de Investigacion Sobre Fijacion de Nitrogeno, UNAM, Cuernavaca, Morelos, Mexico
J Bacteriol 185:1681-92. 2003..Finally, we did not detect expression of traM, indicating that in p42a TraM may be expressed so weakly that it cannot inhibit conjugal transfer, leading to the unrepressed transfer of p42a...
Recurrent DNA inversion rearrangements in the human genomeMargarita Flores
